起重力矩限制器与起重量限制器,是塔式起重机上两套必不可少的安全保护装置。塔机管理人员和工人如果对这两套安全装置的作用和调试方法缺少了解,不能正确发挥这两套安全装置的作用,容易导致塔机超载事故的发生。起重力矩限制器起限制塔机最大起重力矩的作用,它可以防止塔机倾 Lifting torque limiter and lifting the weight limiter, is the tower crane on the two sets of essential safety protection device. If the tower crane managers and workers lack the understanding of the functions and debugging methods of these two safety devices, they can not properly play the role of these two safety devices and easily lead to overloading accidents of the tower crane. Lifting torque limiter from the tower crane limit the role of the maximum lifting torque, which can prevent tower dumping
