FIELD: transportation.
SUBSTANCE: invention relates to hoisting machines and can be used in assembling, dismantling and rearranging overhead cranes in a completely assembled state. The hoist comprises a telescopic boom which is mounted by the internal section on the rotary platform of a mobile crane, and carriages of a hydraulic lift with a crossbeam move on the external section of the telescopic boom. The telescopic boom can also be mounted on the rotary platform in a vertical position.
EFFECT: achieving high mobility using a rack-mountable hoist to assemble, dismantle and rearrange cranes in a single pass, enabling use of low-capacity cranes when assembling overhead cranes before hoisting thereof in an assembly and high technological effectiveness of hoisting.
