SELF-LEVELLING DEVICE FOR SELF-PROPELLED CARRYING AND LIFTING MACHINES Russian patent published in 2008 - IPC B66C23/78 B66C5/00 

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.
