Lifting devices are widely used for maintenance of trucks, tractors and other vehicles. Using these devices, machine post, in whole or in chechenitsky, hydraulic and mechanical lifting devices [1-5].

A common shortcoming of these devices is that they are complex. In addition, the lifts [1-4] are driven from the power plant.

The closest technical solution, selected as a prototype, is vyveshivayuschee device with a support wedge, consisting of a base; two reference-vyvalivaya elements rigidly mounted on a supporting surface with a treadmill and having the opportunity to interact with the beam axle of the vehicle. Each of these items placed on the rack; made with the tip pointing in the direction opposite to the movement of the vehicle when installed on the service, and with emphasis in the form of a ledge [6].

A disadvantage of the known construction is that the hanging bridge is accompanied by an increased friction of the beam on the working faces of the supporting-vyvalivaya elements. In this regard, there are higher energy costs of the process hanging.

The objective of the invention is the creation of energy-efficient lifting device of simple design.

To solve this problem in vymeshivaem device containing osyh on the base and having the opportunity to interact with the beam axle of the vehicle, and including each rack of rectangular or square section and a removable top, made with the working face, which is applied to the lubricant, with the edge directed in the direction opposite to the movement of the vehicle when it is set on the service, and located opposite the tip, a focus for contact with the beam axle of the vehicle, the upper portion of each supporting-vyveshivayuschee element installed on the corresponding rack with adjustable height position, the rack support-vyvalivaya elements mounted on the fixed cross beam can travel along it, referred to the upper part of each support-vyveshivayuschee item is made in longitudinal section in the form of an oblique line with a sharp front and a straight rear corners and the formation of the horizontal working faces on each line treadmill made to deepen respectively for left and right wheel post of the axle of the vehicle, having in longitudinal section the shape of an isosceles trapezoid facing the base, forming with the sides of the trapezoid obtuse angles, down, and each recess width of the foam coasters reference-vyvalivaya elements with the possibility of installing girder bridge on the working faces of the supports, and with the possibility of removing the bridge from these stands when the overrunning wheel of grooves on the bearing surface running track, and on each upper part of the emphasis is on the possibility of its installation in an upper position above the working face of this part, and the bottom is at or below the face.

Deepening can be fitted with protective caps.

The invention is illustrated in the drawings, where Fig.1 shows vyveshivayuschee device, General view, Fig.2 - the same, top view.

The device consists of two supporting-vyvalivaya elements rigidly mounted on a supporting surface of the base 1 between the lines treadmill 8, and two recesses 2 respectively for left and right wheel post bridge machine made one for each line of the above tracks. Each element consists of 7 hours of rectangular or square cross section, the upper part of which is made removable in the form of the stand 3 in the form of a parallelepiped with one of the upper horizontal working edge and edge directed against the movement of the machine when it is installed on the service (the direction of movement of the machine shown by the arrow). In longitudinal section, the stand 3 is of the form l is, opposite the edge attached to the stop 4, made with possibility of installation in two positions: at the top - above the working face of the stand 3 and the bottom is at or below the face (lower position of the stop 4 is not shown). For regulating the stand 3 in height it is installed on the rack 7 with the possibility of vertical movement along the guide rails 6, which are rigidly attached to the cradle 3. In rails 6 between the stand 3 and the rack 7 is provided shims 5, and between these guides and the side faces of the rack - gaps. For adjusting the position of the reference-vyvalivaya elements across the width corresponding to the track service machines, front 7 can be installed on the transverse beam (not shown) to move it in the longitudinal direction. When this beam is still installed on the base 1 between the lines treadmill 8. In addition, the hospital wishes reference-vyveshivayuschee elements through rack 7 can be mounted in the base 1. Field 7 hours or beam under these racks can be similarly installed in the ground. Each recess 2 is a longitudinal cross-section the shape of an isosceles trap is analisemos service. The deepening 2 located relative to the stand 3 with the possibility of installing girder bridge machine on the working faces of the supports 3 at the time of rolling of the wheels with the support surface of the track 8 in the recess 2, as well as the possibility of removing the bridge from these stands when the overrunning wheel of the recesses 2 on this track. In addition, recesses 2 are provided with a removable protective covers (not shown) that are mounted over the recess 2 at the level of the surface of the base 1.

The hanging of the front axle of the vehicle, such as a car, is as follows. Pre (if necessary) adjust the position of the supports 3 height spacers 5 so that the upper horizontal face of each stand 3 was slightly below the bottom of the girder bridge. The working faces of the supports 3 is applied grease. Remove the cover from the recesses 2. The machine runs its course on the treadmill 8 in the direction of the arrow. A beam bridge is over the working faces of the stand 3. At this moment its wheels under the action of gravity roll down from the supporting surface of the treadmill 8 in the recesses 2, without touching their bases. At the same time due to the driving force and the inertia of the vehicle b is egenie. The vehicle moves forward. Under the action of the driving force of the wheel slides out from the recesses 2 on the supporting surface of the treadmill 8: the beam bridge, rising, is removed from the stand 3. Hanging out of the middle, and then the rear axle carried out in the same way. To do this, move the stop 4 in the upper position and, if necessary, adjust the position of the supports 3 height. Then the car continues to move forward, hung out the middle bridge. After his service lowered the stop 4. Take the wheels of the middle axle on the base surface of the treadmill 8 and set the stop 4 in the upper position. Then the car again move forward - hung rear axle. At the completion of the stop 4 lead in the top position. Produce the service of another machine or recesses 2 closed lids.

The proposed device is energy efficient and has a simple structure. The process of posting is transient and lasts for a few seconds, which is due to the fact that the device is equipped with two anchor-vyveshivayuschee elements in the form of supports with a horizontal working faces, a two recesses made on the lines of the treadmill in the form of an isosceles trapezoid, with obtuse angle to the working face of the stand, and after service - removing beams with supports. The hanging bridges is in turn under the action of the driving forces of inertia and gravity service machines. The device can be applied both in the hospital and in the field.
