MECHANISM OF LIFTING CRANE LEVELING SYSTEM Russian patent published in 2021 - IPC B66C13/00 

FIELD: lifting mechanisms.

SUBSTANCE: invention relates to lifting mechanisms and can be used in construction of railway cranes. The mechanism of lifting crane leveling system contains a platform frame carried by the undercarriages, tilt sensors and hydraulic cylinders controlling the platform tilt, in which the platform frame is supported by wedge-shaped slides on undercarriages in form of railway trolleys through intermediate beams with beveled edges in the sliding zone, and the hydraulic cylinders are double-acting and fixed in the trunnions of secondary beams with rods carried by platform frame. Secondary beams with possibility to rotate in horizontal plane are pivotally connected with platform frame.

EFFECT: alignment of railway crane platform is achieved in the direction transverse to the axis of the track.
