Hook retracting device of lorry-mounted crane and lorry-mounted crane

Abstract

The invention provides a hook retracting device of a lorry-mounted crane and the lorry-mounted crane, and relates to the technical field of cranes. The hook retracting device of the lorry-mounted crane comprises a rotating support. The rotating support is rotatably connected to the arm head of the lorry-mounted crane. When the lifting hook assembly of the lorry-mounted crane is in a suspended state, the rotating support is located above the lifting hook assembly and is arranged in the vertical direction, and the rotating axis of the rotating support is offset relative to the center of the lifting hook assembly; and when the lifting hook of the lifting hook assembly is folded, the rotating support can abut against the installation frame of the lifting hook assembly. According to the hook retracting device of the lorry-mounted crane, the lifting hook and the steel wire rope can be retracted so that the swinging of the lifting hook or the steel wire rope is avoided, and the safety threatto the vehicle, the carried goods and the personnel caused by the swinging of the lifting hook or the steel wire rope is eliminated; besides, the lifting hook and the steel wire rope are retracted sothat visual disturbance and driving interference of the driver in the transportation process can be reduced, the driver can drive the vehicle conveniently and the driving safety can be improved.
