OUTRIGGER OF LIFTING MACHINE Russian patent published in 2023 - IPC B66C23/80 

FIELD: hoisting and transport engineering.

SUBSTANCE: invention relates to the field of hoisting and transport engineering, namely to hoisting machines and can be used, in particular, in the design of the support circuit for mobile cranes. The outrigger of the hoisting machine contains a base, in which a vertically oriented suspension hydraulic cylinder is placed, fixed with its upper end to the base and having a ball heel screw at the lower end resting against the thrust bearing. The support is equipped with a retractable beam placed with the possibility of vertical movement and fixation in the base coaxially with the suspension hydraulic cylinder, and the screw at the lower end of the suspension hydraulic cylinder is provided with a union nut on which the retractable beam rests. The base can be provided with a latch with a spring, and holes are made in the retractable beam to receive the latch. The sliding beam is in contact with the side walls of the base through the sliding stops.

EFFECT: elimination of the possibility of subsidence of hydraulic cylinders for hanging outriggers when they are in the working position for a long time.
