Main function of lifting torque limiter


2024-12-24

The main function of the lifting torque limiter is to prevent tower cranes from overloading and avoid serious accidents such as overturning or arm folding caused by severe overloading. It monitors the load of the crane and the angle of the boom in real time, displays the rated load and actual load, and cuts off the power supply of the lifting mechanism when the load exceeds the rated value, thereby protecting the tower crane from damage. ‌
The lifting torque limiter is usually installed on the main chord of the tower top structure, and the protection mechanism is triggered by detecting the deformation of the main chord. It has an independent control system that can automatically detect the working conditions of the crane and quickly alarm and control in dangerous situations. It has a function similar to a "black box", recording the dangerous working conditions during operation and providing a basis for accident analysis.
