Vehicle-mounted folding hand-operated crane

Abstract

The invention discloses a vehicle-mounted folding hand-operated crane. The vehicle-mounted folding hand-operated crane comprises a folding support, a hand-cranking hoisting device, a lifting hook device, a rotating base and a rod folding locking device, wherein the folding support comprises a stand rod, a transverse rod and an inclined rod, the hand-cranking hoisting device comprises a gear reducing mechanism, a gear reducing mechanism base, a lifting rope winding and unwinding coiling block and a jiggle bar, and the lifting hook device is arranged on the upper side of the transverse rod and comprises a lifting hook, a lifting rope and a plurality of lifting rope supporting wheels. The vehicle-mounted folding hand-operated crane is small in size, high in bearing force, reliable in structure, convenient to install and convey, and capable of being located in the required direction to be used in a rotating mode, the folding support can be conveniently stored at the vehicle top after falling down, and the height of the folding support does not exceed that of a guard bar at the vehicle top. The shape of the vehicle-mounted folding hand-operated crane is changed by being used vertically, folded and stored, and miniaturization, practicality and beauty of the vehicle-mounted crane are achieved.

Description

technical field [0001] The invention relates to a vehicle-mounted lifting device for a special vehicle, in particular to a foldable and stowable manual crane arranged on the top of a van or vehicle-mounted shelter, and belongs to the technical field of vehicle accessories.
