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.
本发明提供了一种随车起重机收钩装置及随车起重机,涉及起重机技术领域。其中,随车起重机收钩装置包括旋转支架,旋转支架可转动地连接于随车起重机的臂头,当随车起重机的吊钩组件处于悬置状态时,旋转支架位于吊钩组件的上方且沿竖直方向,旋转支架的转动轴线相对于吊钩组件的中心偏置;收起吊钩组件的吊钩时,旋转支架能够与吊钩组件的安装架抵接。该随车起重机收钩装置可以将吊钩和钢丝绳均收起,从而避免了吊钩或钢丝绳的甩动,进而消除了由于吊钩或钢丝绳甩动而造成的对车辆、所载货物及人员的安全威胁;此外,将吊钩和钢丝绳收起,还减少了运输途中驾驶者的视野障碍和驾驶干扰,从而方便驾驶者驾驶车辆及提高行驶安全性。
