As one of China’s top 3 crane manufacturers, the cantilever crane is one of our main products. To protect the cantilever jib crane better when working, generally, we will equip the safety device on the jib crane, like an overload limiter, height lifting switch, travel limit switch, etc. The overload limiter can help clients monitor the real-time lifting weight, and when the lifting weight is over the capacity, it will sound an alarm to remind clients. However, most clients don’t know the cantilever cranes well, so they may not pay attention to the overload protection device. Now, I will introduce how to check whether the overload protection device of the cantilever crane meets the requirements.
