1. Introduction and Application: The lifting capacity limiter is also known as the overload limiter or load limiter. However, it is different from the torque limiter. The working principles and scenarios of the two are not the same (the difference between the torque limiter and the overload limiter). The lifting capacity limiter is composed of sensors, operational amplifiers, control actuators and load indicators...

In construction sites, port terminals or industrial plants, the stable operation of heavy equipment cannot do without the support of safety protection devices. Torque limiters and overload limiters, as two types of core safety devices, are often confused with the same function, but their actual effects are significantly different. This article will analyze through specific cases and principles,...
