The invention provides a hoisting assembly for a crane, and relates to the technical field of hoisting assemblies. The device is used on the double-beam crane and comprises a group of beam bodies and a walking frame which are arranged on the double-beam crane in parallel, sliding rails are arranged at the tops of the beam bodies, and walking wheel assemblies are arranged at the bottoms, close to the two ends, of the walking frame; the walking wheel assembly is in sliding connection with the sliding rail and makes friction contact with the side face of the sliding rail. The braking mechanism is used for braking the power wheel assembly and comprises a locking claw assembly and a locking claw driving part, the locking claw assembly is rotationally connected to the bottom of the walking frame, the locking claw driving part is fixedly connected to the bottom of the walking frame, and the action end of the locking claw driving part is in transmission connection with the locking claw assembly. The walking frame can be stopped and fixed at any position, the walking frame is not prone to shaking and local displacement during hoisting work, construction safety is guaranteed, and the performance of the crane is improved.
本发明提供用于起重机的起吊组件,涉及起吊组件技术领域。用于双梁起重机上,包括双梁起重机上平行设置的一组梁体与行走架,梁体的顶部设置有滑动轨道,行走架的底部且靠近两端均设置有行走轮组件;行走轮组件与滑动轨道滑动连接,行走轮组件与滑动轨道的侧面摩擦接触;还包括对动力轮组件制动的制动机构,制动机构包括止动爪组件、止动爪驱动件,止动爪组件转动连接于行走架的底部,止动爪驱动件固定连接在行走架的底部,且止动爪驱动件的动作端与止动爪组件传动连接。实现行走架任意位置的停止固定,进行起吊工作的时候行走架不易发生晃动和局部位移,保证施工的安全性,提高起重机的性能。
