The invention provides a hoisting tackle which comprises a protective plate set, a lifting hook and a pulley, the pulley is rotatably arranged in the protective plate set, one end of the lifting hook extends into the protective plate set and is rotatably connected with the protective plate set, and a rope hanging area is formed in the area between the connecting position of the lifting hook and the protective plate set and the pulley. And one side of the protection plate group and the solid structure corresponding to the rope hanging area are detachably arranged. According to the scheme, the structure that the opening of the rope hanging area is opened and closed in a rotating mode in the prior art is replaced with the structure that the opening of the rope hanging area is opened and closed in a detachable mode, and the situations that the structure of the opening of the rope hanging area is opened and closed in a rotating mode, the rotating opening and closing difficulty is correspondingly increased along with increasing of the specification of the hoisting tackle, rope hanging efficiency is affected, and potential safety hazards exist are avoided; and meanwhile, a rotating opening and closing distance and a distance required by safe rope hanging of an operator do not need to be reserved on the opening side of the rope hanging area, rope hanging can be carried out in a working environment with a small space, and the applicability of the hoisting tackle is improved.

    本发明提供了一种起重滑车,起重滑车包括护板组、吊钩和滑轮,滑轮可转动地设置在护板组内,吊钩的一端伸入护板组内并与护板组转动连接,吊钩、护板组的连接位置与滑轮之间的区域形成挂绳区,护板组的一侧与挂绳区对应的实体结构可拆卸地设置。采用本方案,通过拆卸开闭挂绳区的开口的结构替换了现有技术中转动开合挂绳区开口的结构,避免了转动开合挂绳区开口的结构随着起重滑车规格增大,旋转开合难度也会对应增加、影响挂绳效率且存在安全隐患的情况,同时不需要在挂绳区开口侧预留出转动开合距离以及操作人员安全挂绳所需距离,在空间较小的工作环境也能进行挂绳,有利于提高起重滑车的适用性。
