The invention relates to the field of lifting and transport machinery, and relates to cranes, formed on the basis of trucks and placed on the frame chassis platform trucks with hydraulic cranes, with multi-tier swivel boom lifting body gripper type.

The inventive crane is designed for loading, transporting from the workpiece to the consumer and mechanized unloading mostly scrap metal.

It can be widely used in various enterprises involved in the Assembly and processing of ferrous and non-ferrous metals, as well as in construction and other sectors of the economy where there is a need in the transportation of materials disordered spatial patterns and sizes, such as construction debris and waste.

From various information sources known number, similar in essential characteristics analogues of both domestic and foreign developments, see, for example, cranes ISS 4032 ZAO BACM (W-l Construction and road machines", No. 10, M., "engineering", 1995, page 31, Fig. 2), ISS A JSC CRUST (W-l Construction and road machines", No. 11, M., "engineering", 1995, page 31, Fig. without a number at the bottom right corner), Loglift-75, Loglift-130 Finnish company LOGLIFT (brochure 2T 1/92,Printed in Finland by Puna Musta, Loglift Oy Ab), G90L, G100L, G125Z German firm EPSILON KRAN GMBH (brochure 9/95, Scharler & Deller, Salzburg), RK 9700 KA, KB Austrian company PALFINGER (brochure 12/92, Printed in Austria by Welsermuhl, Wels), lomboz-samoborski made by the Institute of VNIIPO "Vtorchermet" in cooperation with Czechoslovakia (Publ.

EN 2140367 C1, B 60 P 1/54, dated 27.10.99,, crane metallogeny tipper type based on a car carrier of the German company Mercedes-Benz, General view of which is shown in Fig. 35, page 125 of the book "vehicle with a lifting device for transportation of cargoes in containers and packages", Migratr, Rastan, Vratimov, M., "Transport", 1989 (UDC 6.29.114.4: 656-135-073-235) and other

As a means of transport in many of the famous cranes-manipulators (ISS-4032, ISS-A, RK 9700 KA, KB and others) are used mainly production car haulers, and for placing the transported materials, including metal scrap, ordinary cargo platform in the form of a trough-shaped body with drop sides, small height.

Loading and unloading of materials using this technique is carried out by lifting mechanisms in the form placed behind the cab or at the tail end of the chassis frame of the tractor water is practical multi-link manipulators with swivel boom, equipped with a lifting body gripper type (e.g., clamshell sublevel, bucket or -). In the transport position, lifting the body of the manipulator in most cases placed directly on the transported material.

This solution is not entirely successful, because when touching connected with sagging to the lifting body flexible hoses, hydraulic drive with sharp edges of the transported material, such as metal shavings, etc. can lead to mechanical damage (failure).

A significant drawback of such machines is the low capacity and a sufficiently large time unloading their platforms. The latter circumstance to some extent can be optimized through the use of unloading more efficient specialized devices, such as electromagnetic type, stationary. However, this is not always acceptable, because such a discharge may be made only in specially equipped places.

The oil tank of the hydraulic system of the manipulator cranes of this type have usually side on the spinal side members of the chassis frame of an automotive truck or above on the basis of a turntable specified handling facilities.

In the first case, the AE he is very poor, operating conditions, the area (too low and can zabrasyvaetsya dirt road when driving), and for fixing it requires a revision of the chassis frame of the tractor.

In the second case is considerably complicated the maintenance of the manipulator in the area of the tank.

Due to the above features of the design such cranes are not perfect appearance (appearance)that do not meet the modern level of development of this technique.

Other known cranes consider destination (Loglift-75, Loglift-130, lomboz-samoborski VNIIPO "Vtorchermet"), in contrast, considered, are composed of specialized platform, consisting of najemnik and welded to it a metal trough-shaped body with rear Windows that double leaf door, is equipped with sucker-rod locking device of the valves in the transport position with the lever mechanism for moving the rod.

Practical experience in the operation of such metallogenic cranes clearly confirms the feasibility of using these platforms in their composition compared to normal body performance serial trucks.

However, because of the way they design have most of the resources from the same disadvantages, inherent in the above analogs.

From this group unique in its circuit-layout and design and external appearance substantially excreted crane NSV 4.00.000 in U.S. Pat. EN 2140367 C1.

The specific layout of the specified valve, caused mainly by the presence of special horses laying on him boom manipulator, welded to the upper edge of the rod locking device of the valves in the rear doors of the body metallophones platform, and located behind it, turning the holder lifting body in the transport position, the powered type allows you to completely eliminate the possibility of damage to the flexible hoses of the hydraulic drive past the transported material, as between him and boom no direct contact.

In its technical and operational characteristics, and appearance at the present time he is one of the best domestic samples of this kind of equipment meeting modern standards for global development.

However, it is inherent in one of the most important drawbacks of the above analogues associated with the imperfection of the unloading of the transported material.

In addition, the location of the oil tank of the hydraulic system of the manipulator in the gap the gap between the base of his turntable and the front is Tenkai body metallophones platform irrational, because it entails a corresponding increase in the length necessary to accommodate the work area.

From among the known analogues of the proposed crane closest (prototype), the most similar in essential characteristics, is the crane metallogeny tipper type based on a car carrier of the German company Mercedes-Benz, General view of which is shown in Fig. 35, page 125 above mentioned book "vehicle with a lifting device for transportation of cargoes in containers and packages.

This crane is characterized by:

the presence of a vehicle in the form of a road tractor;

- mounted on the chassis frame of an automotive tractor by means of detachable connections metallophones platform, consisting of najemnik and articulated with him trough-shaped body with rear Windows that double leaf door, is equipped with sucker-rod locking device of the valves in the transport position with the lever mechanism for moving the rod, forcibly tilt back with standalone lift, made in the form placed under the bottom of the body, two coupled multistage hydraulic cylinders single acting with telescopically retractable links and tilting process is digitalnymi heads on the basis of a spherical or other types of hinges, rigidly fixed to the respective Presedintele body and nadramia;

- have metallophones platform device fixing the leaves in the rear doors of the body at the open position;

the presence of a lifting mechanism in the form placed behind the cab car carrier manipulator with fixed or detachable outriggers, multi-link articulated lever rotary shaft, provided with a lifting body gripper type and hydraulic system oil tank.

In the transport position of the boom, manipulator of this known valve is placed in the body metallophones platform directly on the transported material. Therefore, in this respect, and in appearance he is inferior to Metallofizika a crane in U.S. Pat. EN 2140367 C1 with a more rational scheme of laying the boom of the crane in the transport position.

However, the obvious advantage of the design of this crane is the mechanization of the process of unloading the transported material by an appropriate tipping body, almost anywhere, including unequipped special handling devices.

The presence of nadramia significantly increases the angular rigidity of the system the chassis frame of an automotive tractor over the amnic" and allows on this basis, to significantly improve the stability of the crane of this type during mechanical unloading of the transported material.

Due to the fact that this well-known crane-manipulator front part of the body metallophones platform in the transport position is not fixed, when the movement of the crane on rough roads which are affected by vertical accelerations can podbrasyvanija up with isolation from nadramia, and then to fall on him.

While on a chassis frame of an automotive tractor apply load shock of nature. In this case, najemnik not only strengthens the chassis frame of the tractor, but also plays a role of a buffer.

The disadvantages of this crane can, perhaps, be attributed circuit-layout decision concerning the location of the cylinders of the body metallophones platform under his bottom.

A number of trucks, mainly serial execution, this can prevent cross frame chassis, drive shafts, gearbox rear axle assemblies brake systems and other elements of the staff filling the space specified.

The inventive crane metallogeny tipper type contains the motor tractor 1, is attached to the chassis 2 chassis 3 of the tractor by means of detachable connections 4 metallophone platform 5 and 6 hydraulic crane.

Metallofizika platform 5 consists of nadramia 7 and articulated with him all-metal coridoors the CSOs body 8 with the rear opening double-leaf door 9, equipped with rod device 10 locking of the valves 11, 12 in the transport position with the lever mechanism 13 to move the rod 14, forcibly tilt back using the standalone lift 15 made in the form of single or two coupled multistage hydraulic cylinders single-acting telescopic sliding parts 16 and pivoting mounting heads 17, 18 on the basis of a spherical or other types of hinges 19, rigidly fixed to the respective Presedintele 20, 21 of the body and nadramia.

Hydraulic crane 6 is placed behind the cab 22 of the tractor 1, formed in the front part metallophones platform 5 by a corresponding displacement of the body 8 in the direction of the rear nadramia 7, the working space 23. To ensure the necessary stability of the proposed crane from tipping over in the design of the manipulator 6 are stationary or portable outriggers 24. For lifting, moving and lowering scrap, it is equipped with multiple-lever rotary shaft 25 with lifting body 26 clamshell type.

Najemnik metallophones platform in this case is the base element for mounting on a body, independent of the hoist, crane, etc. since it is directly on the frame W is fid serial trucks, often used in composition of such cranes, does not provide the appropriate seats and fastening elements.

Mount these units crane on the chassis frame of an automotive tractor through najemnik provides the necessary stiffness and joint deformation of the frame and nadramia under the action of a operational loads. The presence of nadramia enables you to evenly distribute the load caused by the weight placed on it equipment, the length of the chassis frame of the car truck.

The device 10 of the locking of the valves 11, 12 of the door 9 of the body 8 is made in the form of a rod 14, is placed can be moved in the vertical direction inside the leftmost amplifier 27 right door 12.

The rod 14 is kinematically communicates through located on the lower edge of its cone tip 28 installed underneath the body 8 metallophones platform 5, with the possibility of adjustment in the longitudinal direction, the horizontal support 29.

Bearing 29 provided for this narrowing down of the Central groove 30 of wedge-shaped profile, oriented parallel to the plane of the door 9.

On the rod 14 in its upper part, a cantilever cylindrical mortgage finger 31. The specified finger 31 with a gap passed through aligned vertical the actual grooves 32 of the leftmost amplifier 27 right door 12 and kinematically communicates with the open top and tapering down the slots 33 in the side walls of the bracket 34 of the U-shaped configuration, welded legs to the far right amplifier 35 left shutter 11 of the door 9 opposite the fixed finger.

At the end of the cantilever part of a mortgage finger 31 is formed restrictive flange 36 that interacts with the side surface 37 a U-shaped bracket 34 on the side opposite the parting line 38 of the valves 11, 12 of the door 9 of the body 8. The specified flange 36 blocks the divergence of the valves 11, 12 of the door 9 of the body 8 in the transverse direction.

A lever mechanism 13 to move the rod 14 of the device 10, the locking of the valves 11, 12 of the door 9 of the body 8 metallophones platform 5 is made in the form attached to the bottom side of the leftmost vertical amplifier 27 right door 12, the side opposite the parting line 38 of the valves, can be rotated in a vertical plane and parallel to them, duplicera lever 39 with a handle 40, ending with the other end of the flat duhabi fork 41, skipped through the aligned vertical slots 42, 43 in the side walls of the specified amplifier and rod and kinematically interacting with opposite her and oriented perpendicular to the plane of the door cylindrical axis 44 rigidly mounted inside the rod.

The rod 14 of the device 10, the locking of the valves 11, 12 of the door 9 of the body 8 metallophones platform 5 is supplied welded to its upper edge lodgement 45 for laying on n the th arrows 25 manipulator 6 in the transport position, bearing surface which is profiled on the outer perimeter of the boom. The upper ends of the side walls of lodgement 45 for laying on him boom 25 manipulator 6 is bent outward forming between them extending up the lead-in part, to facilitate semioriental arrows in the process of laying her on the bed.

The device 10 of the locking of the valves 11, 12 of the door 9 of the body 8 metallophones platform 5 is equipped with interchangeable stopper 46 pin-type mechanical blocking unauthorized movement of its rod 14 in the upper direction. Such movement of the rod 14 can occur if you accidentally capture bent outward ends of the side walls of lodgement 45 rising arrow 25 manipulator 6, and during movement of the crane on rough roads, when under the influence of the corresponding vertical accelerations of the body 8 metallophones platform 5, and thus the rod can podbrasyvanija up. While the tapered tip 28 and the cylindrical mortgage finger 31 of the rod 14 can exit respectively of the slots 30 and 33 bearing 29 and a U-shaped bracket 34, which will lead to the unauthorized disclosure of the valves 11, 12 of the door 9 of the body 8 metallophones platform with all the ensuing consequences.

Having specified the stopper 46 eliminates the likelihood of such events

In the design metallophones platform 5 there are two quick-release mechanism 47 coupling type fixing of shutters 11, 12 of the door 9 of the body 8 in the extreme open position.

These mechanisms 47 are made in the form attached to the sides 48, 49 of the body 8 metallophones platform 5 within reach from the ground level compression of the chains 50, put on welded across them to shutters 11, 12 doors 9 hook the hooks 51.

Data locking devices and mechanisms have sufficiently high performance and reliability, and fit perfectly into the design metallophones platform without distortion geometric lines and deterioration of its appearance.

Autonomous body lift 15 8 metallophones platform 5 spatial is a slit opening formed between the front wall 52 of the body and the manipulator 6 is oriented vertically and the kinematic connection of its closing sliding link 16 with the connector body 21 through the back 53 of the flat swinging of the rocker arm 54 of the U-shaped configuration, the ends of which are movably associated with the specified body wall near its bottom by means of two oriented in the transverse direction and coaxially located with respect to each other cylindrical hinge 55.

Such circuit-layout performance standalone is jamnica body metallophones platform has a number of advantages:

it allows the body with a vertically oriented, and not inclined wall, resulting in a corresponding increase in its capacity;

- concentrated load acts on the body in the area of the front wall, having a greater transverse rigidity, while at the location used for body lifting telescopic hydraulic cylinders underneath it acts on the flat bottom of the body, which forces to strengthen its additional load bearing beams;

- when the selected layout easier access to the telescopic cylinder when maintenance is required.

Autonomous lift such performance is perfectly integrated in the design of the proposed crane and essentially virtually invisible from the side, and lifting transforms into a delicate link acicular profile linking najemnik and body, allowing the crane visually perceived extraordinarily graceful and lightweight.

In the design metallophones platform 5 provides a mechanical stop 56 of the rotating body 57 telescopic hydraulic cylinder 15 lifting her body 8 around the longitudinal axis, made in the form of rigidly fixed on nagranie 7 stops kinematically coupled with sformirovannym corresponding Bonke 58 housing, by enabling seamless corner move it together with the swing arm 54 in the plane of the lifting / lowering of the body, a removable grip 59.

This solution is extremely simple and eliminates the twisting body of the telescopic cylinder around its longitudinal axis, and hence the emergency break for this reason, the flexible hose supply the working fluid. Spatial specified limiter is located in the area of najemnik and almost invisible from the side.

Metallofizika platform 5 of the proposed crane provided with a limiter 60 height body 8 made in the form of wire loops of variable length connecting the body with nadramia 7 with the necessary slack her sagging.

The specified delimiter captures the maximum height of the lifting body and greatly increases the security of the proposed crane by insurance body from tipping over on its ascent in case of emergency destruction of telescopic hydraulic cylinder 15. The installation and adjustment extremely simple. Spatial location makes it invisible from the outside.

In the design metallophones platform 5 provides a fast mechanism 61 commit her body 8 in the extreme raised position, the imp is United in the form of two removable technological pins 62, entered in this position provided for this purpose in kinematically matched between the power elements of the body and nadramia 7, near the transverse cylindrical hinges 63 joints corresponding to the mounting holes 64.

In the transport position, these pins are placed in holes 65 a specially formed under the bottom of the body shops 66. They provide the necessary security service of the respective units of the proposed crane when raised to its extreme upper position the body and does not spoil its appearance, since escaped from the steel body.

Metallofizika platform 5 is equipped with raznesennymi between the upper shelves 67 spinal side members 68, 69 nadramia 7 and the bottom of the body 8 flat elastically deformable damper 70. Structurally they can be fixed to the bottom of the body or above the shelves of the spars.

When lowering and tosses the body metallophones platform during movement of the crane on a rough road these absorbers significantly soften the blows him about najemnik.

In the design metallophones platform 5 of the proposed crane has a powered holder 71 hauling 26 arrows 25 in the transport position, made in the form of Sha is Nino mounted on the rear bottom of the body 8, can be rotated in a vertical plane along it, the leash 72 U-shaped configuration, interacting with covering it up to full clamping jaws 73 hauling.

Metallofizika platform 5 is equipped with high-speed on-off mechanism 74 forced commit leash holder 72 71 hauling arrows 25 manipulator 6 in the transport and working positions, made in the form of kinematically coupled with one of the side racks leash, with an offset from the axis of rotation, and the bottom of the body 8, a tension spring 75 to the device 76 lock scattering its parts in case of emergency destruction.

The specified device 76 lock made in the form of missed, with the necessary degree of sagging, through the spring 75, a safety cable 77, the ends of which are fixed in places of fastening of the spring, and put on her protective sheath 78 of high-strength legkodeformiruemyh material, such as a tarpaulin.

In principle, it is possible embodiment of a protective case and two telescopically jointed thin-walled metal pipes.

Implemented in the inventive crane-manipulator design powered holder lifting body of the crane in the transport position, simple and very convenient in exploatatiilor forced commit leash in the extreme upper position, the operator does not present any difficulties when laying arrows on lodgement of the rod locking device of the valves in the rear doors of the body almost blindly, without assistance, to capture its open jaws hauling with the subsequent closing them and the tension on the leash.

In case the leash flexible, for example in the form of a corresponding chain or rope loop, this would require much more time or additional involvement of support staff. Evacuation leash before lifting body under najemnik almost completely eliminates the possibility of accidental breakage when the specified operation. Transfer it from one position to another is easy and almost instantly, within a few seconds. The size and shape of it is quite small and does not spoil the appearance of the proposed crane.

In the design metallophones platform 5 provides a mechanism 79 auto-commit and released the swinging of the rocker arm 54 of the body 8 when lowering and lifting, made in the form formed on the front wall 52 of the body 8, in front of the back 53 of the rocker arm, and behind him, on nagranie 7, controlled by the thickness of the elastically-deformable and two spaced between a hard limiters 80-82 its angular travel, interacting with one hand with backrest specified rocker, and on the other, with a formed at the ends of the mechanical stops 3.

This mechanism eliminates the possibility of collision of the swing beam, and hence the telescopic lift cylinder body metallophones platform with its front wall and a crane when moving the crane. Fixation of the beam using conventional stopper pin type in this case is invalid because the operator may forget to remove it before lifting the body and for this reason, as shown, the telescopic cylinder when performing the specified operation can be broken.

The body 8 metallophones platform 5 is provided with a rigidly fixed at its front wall 52 with a corresponding diversity in height and in the transverse direction of lestnichnyj brackets 84.

These brackets don't clutter up the working area of the proposed crane and provide, if necessary, unhindered access to the upper edge of the body metallophones platform and the back of the swing arm.

As hydraulic Autonomous body lift 15 8 metallophones platform 5 in the inventive crane-manipulator used zadeystvuya from the motor car carrier 1 standard hydraulic system 85 manipulator 6 with the tank 86 and modified for this purpose the valve 87 controls the outriggers 24.

As part of the specified valve 87 OEM home button Flex cable is the TREN designed to enable lift 15 additional working section 88 of spool type with lever arm 89 to move the spool 90, communicated with the working cavity of the lift through the valve 91.

This solution is very convenient for both the manufacturer and user of the inventive crane. It allows in this case to reject the creation of an independent additional hydraulic circuit feeding the working fluid telescopic lift cylinder body metallophones platform and, on this basis, to significantly simplify the design of the proposed crane, to reduce the cost and improve its appearance.

The tank 86 85 hydraulic manipulator 6 is placed on nagranie 7 metallophones platform with a transverse offset it to the periphery with respect to its longitudinal axis, in the alignment between the front wall 52 of the body 8 and one of the outriggers 24 manipulator, opposite the swivel 92.

This placement of the tank is very favourable for its operation. The offset from the front wall of the body metallophones platform to swing stand manipulator allows to minimize the length of the working area of the platform and the respective connection lines hydraulic system. Due to the rather high location, it is practically thrown dirt road during the movement of the crane. Access for maintenance is convenient and does not cause as the difficulty.

On the side of the working platform 23 metallophones platform 5 in the area of the manipulator 6 and lift 15, the side opposite to the placement of the tank 86, fixed ladder 93 hinged type for lifting her staff and leaving her after work.

Arrow 25 manipulator 6 in the transport position by means of an appropriate transformation is stretched in a line with orientation along metallophones platform 5 in the direction of the door 9 of the body 8 and laid her remote section 94 lodgement 45 rod 14 of the device 10 of the locking valves 11,12, with subsequent capture outstretched leash holder 72 71 interlocking thereafter until full contact jaws 73 hauling 26 and tension its corresponding extension of the telescopic section 95 of the boom.

This layout provides a rational laying and fixing of arrows with gruzozahvatnym body of the manipulator without touching them with perevozki body metallophones platform material.

This feature virtually eliminates the possibility of damage have on the boom and lifting the body of the flexible hose for supplying the working fluid perevozki material.

Translation arrows and hauling manipulator according to this scheme of R. the working position to transport position and Vice versa is carried out with the operator's fast enough, in just a few seconds and without additional involvement of support personnel.

Implemented this layout aspect ratios from the lower edge of the wheels of the tractor 1 to the upper edge of the body 8 metallophones platform 5 and the axis 96 of the site pivotally connecting the boom 25 to the steering rack 92 manipulator 6, height and length of the body, the magnitude of the step placement of vertical reinforcing amplifiers 97 on the front surface of the sides 48, 49 of the body and its length respectively of the order 1:(1,1...1,2); 1:(2,7...3,0)and 1:9.

While the first of these ratios provides maximum utilization of the working space of the proposed crane height, with formation of the necessary clearance between the top slice of the body metallophones platform and the boom of the crane in the transport position, excluding mechanical contact her with the transported material.

Second, with respect to the first, as well as features of the structural design of Autonomous lift and placement of the oil tank hydraulic system hydraulic manipulator, provides the maximum possible body metallophones platform at optimality its proportions relative to the other parts of the proposed crane.

The third ratio allows to put into effect the performance on the lateral sides of the body metallophones platform slim system are separated by their length decorative vertical protrusions, significantly improves the appearance of the proposed crane and giving at the same time the necessary rigidity and strength to the body.

The inventive crane is equipped with raznesennymi on the cab 22 car carrier 1 and the body 8 metallophones platform 5 dopolnitelnye side signal reflectors 98 spaced along their length.

When lighting them outside light, for example, headlights of passing cars are clearly visible corresponding dimensions of the proposed crane in the dark.

Works claimed crane as follows. Arriving at the venue operations, choose the position of the crane, providing the most convenient and the front from one installation, place it in the selected position and translate the outriggers 24 manipulator 6 in the working position with the extension of their bearing abutments 99 before contact with the ground. Then by retracting the telescopic section 95 of the arrows 25 weaken the tension of the leash 72 of the holder 71 and Razumkov jaw 73 hauling 26 lifting from the bed 45 of the rod 14 of the device 10, the locking of the valves 11, 12 of the door 9 of the body 8, remove it from engagement with the specified leash.

This leash holder 72 71 remains in its extreme upper position. Further, manipulating, accordingly, the existing image of the arrow 25 manipulator 6, down lifting the body 26 to the immersed material and seize him by the clamping jaws 73.

Then, visually verifying the reliability of the capture material with appropriate movements of the boom 25 transfer it to the body 8 metallophones platform and unload on him, breaking the jaw 73 hauling 26. And so, many times repeating these operations, fully loaded with scrap metal body 8.

Because scrap metal is usually irregular spatial structure, in the process of loading it into the body 8 on its walls are appropriate arching efforts. Under the action of the doors 11, 12 of the door 9 of the body 8 tend to disperse from their connector 38 in the longitudinal and transverse directions. However, inherent in the design of the device locking the valves 11, 12 of the door 9 of the body 8 technical solutions virtually eliminate it.

After full loading them body 8, operating in the reverse order, transfer crane in the transport position.

When translating the crane in the transport position the arrow 25 manipulator 6 transform in line with the orientation along metallophones platform 5 and simultaneously unlock the jaw 73 hauling 26. Then tilt it downward toward the rear door 9 of the body 8 and stack remote CE is of 94 on lodgement 45 rod 14 of the device 10, the locking of the valves 11, 12 doors.

At the end of the lower boom 25 leash holder 72 71 hauling 26 is between its open jaws 73. In this position by means of clamping jaws 73 hauling 26, until they contact, carry out the seizure of their leash holder 72 71 with the subsequent tension by appropriate extension of the telescopic section 95 of the arrows 25 manipulator 6. And only after that, convinced of the reliability of fixing of arrows 25 lifting body 26, is transferred into the transport position the outriggers 24 manipulator 6.

After delivery of scrap metal to the place of consumption unloading his perform dump method.

To do this, again, above the image, translate the outriggers 24 and bolt 25 manipulator 6 in the working position with the last evacuation from the zone of location of the body 8 metallophones platform 5. After you perform this operation manually by an appropriate rotation around its own axis of rotation transfer free leash holder 72 71 lifting body 26 from the top to the lowest position, under najemnik 7 metallophones platform 5. Then, after removing the stopper 46 and using the handle 40 duplicera lever 39 mechanism 13 to move the rod 14 of the device 10, respexit sash 11, 12 of the door 9 of the body .

For this purpose, the handle 40 of the lever 39 is turned down. This duhsasana fork 41 of the lever 39, interacting with the cylindrical axis 44 of the rod 14 moves past up.

When moving the rod up 14 located on the lower edge of its conical tip 28 is withdrawn from engagement with the fixedly mounted underneath the horizontal support 29, and the console is attached to the upper part of the cylindrical rod mortgage finger 31 from the grooves 33 of the bracket 34 and the left shutter 11 of the door 9 of the body 8.

After the release of these valve elements 11, 12 of the door 9 of the body 8 are rusticyanin and open them by turning manually hinged loop hangers 100, toward the respective sides 48, 49 of the body. In the extreme open position of the sash 11, 12 is attached by mechanisms 47 by snapping chains 50 on their hook the hooks 51.

Dumping 8 metallophones platform 5 is then dump path.

For lifting body 8 a corresponding movement of the spool 90 additional work section 88 of the valve 87 by means of the handle 89 serves the working fluid from the sump 86 85 hydraulic manipulator 6 into the working cavity of telescopic hydraulic cylinder 15.

Under the action of pressure coming into the specified cavity telescopic hydro is elendra 15 through pressure opened the window of the spool 90 of the working fluid is the progressive extension of its telescopic links 16 and respectively the rise of the body 8 with automatic unloading in it material.

Required for such discharge limit lift height body metallophones platform is determined by the corresponding amount of slack rope loop limiter 60. In case of emergency destruction of telescopic hydraulic cylinder 15 tipping rising body guaranteed excludes the specified limiter 60, ensuring its appropriate mechanical insurance.

If necessary, stop raising the body 8 in any of the intermediate positions it is done by an appropriate translation of the handle 89 additional work section 88 of the valve 87 in a neutral position. In this case, the pressure window of the spool 90 the specified partition 88 is completely blocked and the working fluid is locked in the cylinder 15, thus preventing accidental lowering of the body 8.

Lowering body 8 after unloading to its original position under the action of its own weight when the outdoor pressure window of the spool 90 additional work section 88 of the valve 87 through which the working fluid respectively displaced from the telescopic cylinder 15 in the tank 86 85 hydraulic manipulator 6.

To open the specified window slide the handle 90 89 additional work section 88 of the valve 87 in this case, move vobrator direction.

During normal operation of the hydraulic system 85 manipulator 6, the working fluid flows through the valve 91 from one cavity to another and back, flowing around his shutoff ball held in open position by the respective spring.

In case of damage (rupture) line power telescopic hydraulic cylinder 15, the pressure of the working fluid in the working cavity starts to fall sharply and shut-off ball shut-off valve 91 under the action of the corresponding velocity head of the fluid that is displaced from the specified cavity, compressing the spring, sits on the valve seat, thus preventing the leakage of liquid from the cylinder, and therefore the emergency lowering of the body 8.

The final part of the landing descending body 8 on najemnik 7 automatically centering the front of the body relative to the longitudinal axis of the chassis 3 car carrier 1 with provision of fixing it in the transverse direction. For this Metallofizika platform 5 is provided with a device 101 automatically coupling and uncoupling the front of the body 8 with its nadramia 7 precluding transverse movement of the body in a lowered position relative to nadramia.

One possible design of such device is shown in Fig drawing.

In this case, it is made of dvuhsotmetrovyh in the area on the side walls 102, 103 ridge shaped side members 68, 69 nadramia 7 with a mirror positioned in front of each other and narrowing upwards, inclined guides 104, 105 and kinematically interact with the lateral wedge grips 106, 107 with identical angles of inclination of their working surfaces rigidly mounted on the lower edge of the body 8 in the same plane with the specified tabs.

When lowering the body on najemnik grips 106, 107, automatically caplease with the tabs 104, 105 device 101, is securely fixed between them in the transverse direction of the body nadramia.

The specified technical solution can significantly improve the dynamic quality of the proposed crane, especially when passing the curved sections of road with great speed.

When lifting body disconnection of the grips 106, 107 with the tabs 104, 105 device 101 is in the automatic mode. Therefore, no restrictions on the freedom of movement of the body in a vertical plane in this case.

In principle, other variants of embodiment of the specified device, for example with its location between spinal spars of nadramia.

At the moment of "landing" of the body 8 on the spinal side members 68, 69 nadramia 7 mechanical blow him about them softened flat providersmichelin dampers 70, whic is its between the bottom of body and top shelves of these spars.

After lowering of the body 8, operating in the reverse order, close the sash 11, 12 of the rear door 9 and fix them by means of locking. For this purpose, the handle 40 of the mechanism 13 to move the rod 14 of the device 10, the locking of the valves 11, 12 of the door 9 of the body 8 is turned down and tightly covering the door leaf. Fixing of shutters 11, 12 of the door 9 is carried out by lowering the rod 14 down, almost under its own weight after you release the handle 40 duplicera lever 39.

When lowering the bar down 14 located on the lower edge of its conical tip 28 is in engagement with the fixedly mounted underneath the horizontal support 29, and the console is attached to the upper part of the cylindrical rod mortgage finger 31 in the grooves 33 a U-shaped bracket 34 left sash 11. Then the rod 14 is blocked by the stopper 46.

After locking the valves 11,12 door 9 of the body 8 raise leash holder 72 71 hauling 26 to its extreme upper position by an appropriate turning it by hand around its own axis of rotation. Then, by performing the above way, the final operation is transferred to the transport position the arrow 25 with lifting body 26 and the outriggers 24 manipulator 6, after which the crane is ready for the next flight.

Sleek shape, symmetry and elegance of lines, the visual is the order of the layout of the proposed crane testify to the high excellence and quality products.

It is beautiful, harmonious and restrained by the strength of their lines and optimal proportions unwittingly attracts the eye and leaves a pleasant impression.
