With the increasing number of overhead transmission lines, lever hoists are often used in line construction and maintenance operations. Nowadays, lever hoists with rated load are used. If the working load exceeds the rated load of the lever hoist, it is likely to cause damage to the chain of the lever hoist such as breaking, which greatly increases the risk of operators and equipment.

 

At present, with the development of economy, overhead transmission lines are increasing day by day, and lever hoists are often used in line construction and maintenance operations. Therefore, the lever hoist plays an important role in the operation, maintenance and overhaul of transmission lines.

 

Nowadays, the lever hoist with rated load is used. It is impossible to measure and judge whether the load on the hoist is within the rated load value during the operation. If the load exceeds the rated load of the lever hoist, it is likely to cause The chain of the lever hoist is broken and other damages greatly increase the risks of operators and equipment. The literature also clearly stipulates that the lever hoist shall not be forcibly overloaded. Therefore, it is necessary to develop a device that can instantly measure the load received by the lever hoist during use, and can give an alarm in time when an overload occurs, and reduce the risk of operation.

 

With the development of the electromechanical industry, it is an inevitable trend for the development of construction technology to realize the mechanization of operations in engineering construction. The lever hoist can be used as the main tool in the installation of mines, chemical industry, electric power industry and other projects, and it is better for traction operations.
