力矩限制器是大型起重机械必须配置的重要安全装置。力矩限制器能够对起重载荷进行实时监测,并对不安全操作进行控制。当起重载荷超过起重机所能承受的载荷即出现“过载荷”情况时,它会给起重机操作者发出警告,并且输出相应的信号以限制起重机的不安全动作。正因为力矩限制器具有上述安全功能和作用,每台机器出厂之前都要对它进行参数标定和载荷检测,检测结果必须符合国家标准的有关规定,自动 Torque limiters are important safety devices that large cranes must deploy. Torque limiters monitor hoist loads in real time and control unsafe operation. When the crane load exceeds the crane can withstand the load is “overload” situation, it will give crane operators a warning, and the corresponding signal output to limit crane unsafe action. It is precisely because of the torque limiter with the above safety features and functions, each machine must be factory before the parameters of its calibration and load testing, the test results must comply with the relevant provisions of national standards, automatic
