LORRY-MOUNTED CRANE Russian patent published in 2008 - IPC B66C23/78 

FIELD: transport.

SUBSTANCE: lorry-mounted crane incorporates a jib, a rotary assembly, a fixed assembly, outboard supports with the crane hydraulic cylinder suspending supports (hydraulic supports). The crane can be suspended on all outboard supports. Note that in the crane suspended position, the inclination of one of outboard supports in its lengthwise vertical plane towards the projection of a perpendicular on the plane of the fixed assembly exceeds the inclination of the other outboard supports in their lengthwise vertical planes towards the projections of the perpendicular to the fixed assembly plane.

EFFECT: increase in tolerable inclination of the crane and its load-lifting capacity in operation on notable slopes.
