Technical Field

The invention belongs to the field of tower cranes in the construction industry, and particularly relates to an intelligent electronic limit switch controller for a tower crane.

Background

A tower crane (short for tower crane) is a hoisting device used for building construction, and a limit switch is a protection device for preventing safety accidents such as top rushing and the like in the running process of the tower crane. At present, most of mechanical cams used in the application field of the tower crane in China are used as limit switch protection devices, the mechanical cam switches have the defects of troublesome installation and debugging, easy damage of mechanical contacts and single function in the application of the tower crane, and safety accidents caused by mechanical limit failure in the operation process of the tower crane are easily caused, and the consequences are very serious.

Disclosure of Invention

The invention aims to solve the defects and provides an intelligent electronic limit switch controller for a tower crane.
