VEHICLE FOR EARTH-MOVING AND/OR LOAD-LIFTING OPERATIONS

摘要

1. A vehicle for earth-moving and/or load-lifting operations comprising a support-rotating device, a platform arranged on a rotatable part of said support-rotating device, a working equipment and an electrical drive mounted on said platform, and said annular current receiver encased in a housing, a rotatable part of which is associated with said platform, and the fixed part is associated with a non-rotatable part of said support-rotating device, characterized in that the vehicle is provided with a mechanism coupling said current receiver with said platform and with a bracket for said current receiver, said bracket is arranged on the non-rotating part of the support-rotating device enabling to turn respective to the axis, which is parallel to the axis of the platform turn. 2. The vehicle as claimed in claim 1, characterized in that the housing and the rotatable part of the current receiver are rigidly connected with each other, said coupling mechanism comprises T-shaped pinion carrier, a horizontal strip and a vertical rod of which are connected by a propeller shaft, and V-shaped prisms mounted on the housing of the current receiver, the strip of the pinion carrier is positioned in the prisms of the current receiver, and the rod of the pinion carrier is mounted on the platform enabling to perform alternate/reciprocal motions, wherein its axis is aligned with the axis of the platform turn. 3. The vehicle as claimed in claims 1 and 2, characterized in that the pinion carrier is provided with a catch of the non-working position, wherein the bracket for the current receiver is provided with a catch of the working position.
