Foot support for stabilisers

FIELD: machine building.

SUBSTANCE: invention relates to stabilisers of self-propelled cranes. The foot support for stabilisers includes the bearing element the housing of which is implemented in the form of a volume figure from plastic or polymeric material, with a larger base located in the lower part and the smaller base located parallel to the bigger base in the top part of the housing, elements for placement of the separable element with the hydraulic or mechanical rack rod. Elements of the separable connection are located on the smaller base of the housing and contain the spherical cavity located in the housing. The neck of the spherical cavity has the diameter, smaller than the diameter of the spherical element connected with the rack rod.

EFFECT: effective and reliable, but fast and convenient separable connection of the foot support with the end of the hydraulic or mechanical rack rod is achieved.

SUBSTANCE: invention relates to machine building. A device to block the telescopic support of a construction machine comprises a casing welded to the outer tube of the telescopic support, the casing is provided with a through round hole having a groove in the vertical plane which is ended by an annular groove, and a steel pin provided with a cross stud to be placed in the through round hole at vertical stud positioning with a rest against the annular groove and insertion of its other end through the holes in the outer and inner tubes of the telescopic support. The other end of the steel pin is fitted by a lock of "washer" type to fix the said pin against slipping in respect to the casing at horizontal stud positioning with a rest against the annular groove due to the thrust of the "washer" lock protrusion against the casing.

EFFECT: prevention of spontaneous or unathorised movement of a construction machine.

SUBSTANCE: invention relates to elevators, particularly, to their control systems. Proposed method comprises primary and final installation. In repeated installation after setting the jack moving part displacement speed, jack operation time is calculated as relationship between required amount of motion of jack moving part to jack preset speed. Jack moving part displacement speed is calculated as relationship between calculated required time and jack operation time. Time count is started to activate all jacks except for reference jack on setting jack moving part calculated speed. After count time from its start elapsed, all jacks are stopped.

EFFECT: reliable horizontal installation of platform.

SUBSTANCE: proposed external support of lifting-and-conveying machine comprises horizontal guide mounted on the latter and incorporating telescoping beam fitted in the said guide to turn about its lengthwise axis. Aforesaid beam incorporates hydraulic jack and second guide. The guides have cylindrical axial cavities with their walls accommodating retainers. Aforesaid beam is supplemented with the second telescoping beam, both representing hollow structures with two guide channels made in their outer surfaces. The guide channel pouter surface represents a part of cylinder with lengthwise axis aligned with that of the seam to form, with aforesaid inner surfaces of cylindrical axial cavities, a telescoping joint. Note that, on the side of aforesaid surfaces, grooves are made their start representing a lengthwise groove receiving retainer pin, changing over into helical groove that makes a quarter of a turn. Note also that aforesaid groove end represents the second lengthwise groove. The cylindrical axial cavities of the guides and telescoping beams accommodate beams drive representing hydraulic cylinders with their one end fastened to the guide, and their second end coupled with telescoping beam.

EFFECT: higher efficiency and reliability.

SUBSTANCE: wheeled truck platform comprises a base accommodating platform floor and sides. Crane-manipulator (14) is mounted on the platform floor nearby the front side. The platform base is linked up with holder (22) arranged behind crane-manipulator (14) and accommodating the shaft with outrigger fitted thereon. The crane-manipulator is shifted to the platform lateral side under which the said outrigger is mounted. Aforesaid holder is furnished with supports representing the plates welded thereto to form feet with holes to mount the ladders. Note that the support posts are attached to the platform base lengthwise beams to form eyelets for the ladders to be mounted.

EFFECT: simpler design and higher reliability.

FIELD: machine construction.

SUBSTANCE: invention relates to the field of machine construction and can be used during the manufacturing of carrying and lifting machines. Self-levelling device for self-propelled carrying and lifting machines contains four hydraulic cylinders of outriggers and the control unit interacting with them. Moreover on the hydraulic cylinders are mounted sensors, which respond to touch of the plunger pin of the hydraulic cylinder with the supporting surface and which gives a signal to the control unit, and on the non-rotational frame is mutually transversely mounted a sensor, which reacts to its deviation to its longitudinal and transverse planes relative to the horizontal plane and which gives signals to the control unit.

EFFECT: automation of the process of the self-propelled carrying and lifting machines in the horizontal plane, and as a consequence cutting time in the adduction of the crane in the working position and increasing accuracy of alignment.
