The invention provides a power-adjustable limiter for a crane, and relates to the technical field of mechanical engineering. The power-adjustable limiter for the crane comprises a first bottom frame, a plurality of supporting columns are fixedly connected to the top of the first bottom frame, a second bottom frame is fixedly connected to the tops of the supporting columns, a driving mechanism is installed at the front end of the top of the second bottom frame, and two supporting iron blocks are fixedly connected to the rear end of the top of the second bottom frame; an annular ring is fixedly connected to the bottom of the second bottom frame, a weight detector is fixedly connected to the bottom of the annular ring, a first steel rope is fixedly connected to the bottom of the weight detector, a control mechanism is installed at the bottom of the first steel rope, and a reaction mechanism is installed in the wire wheel mechanism. According to the crane, the control mechanism and the reaction mechanism are designed, so that when the crane lifts an object, the reaction mechanism immediately responds to stop the lifting working process, dangers are avoided in time, and the safety of the lifting process is improved.

    本发明提供一种可调节功率型起重机用限制器,涉及机械工程技术领域。该可调节功率型起重机用限制器,包括第一底架,所述第一底架顶部固定连接有多个支撑柱,多个所述支撑柱顶部均固定连接有第二底架,所述第二底架顶部前端安装有驱动机构,所述第二底架顶部后端固定连接有两个支撑铁块,所述第二底架底部固定连接有环形圈,所述环形圈底部固定连接有重量检测器,所述重量检测器底部固定连接有第一钢绳,所述第一钢绳底部安装有控制机构,所述线轮机构内部安装有反应机构。通过设计控制机构和反应机构,使得在起重机对物品进行起重时,反应机构立即作出反应,制止起重的工作过程,及时避免危险的发生,进而提高了起重过程的安全性。
