Hongda tower crane is a combination of advanced technologies of the present day. It is equipped with a hydraulic self-raising mechanism.

The electric control system of the tower crane adopts the advanced “PLC” control mode of the present day, which greatly improves the reliability, maneuverability and stability of the control system and the work efficiency of the tower crane.

Hongda tower crane is equipped with all kinds of reliable safety devices, such as hoisting height limiter, slewing range limiter and multifunctional limiter to control the load moment, hoisting capacity and trolley traveling range. Its PLC (Programmable Logic Controller) unit can diagnose the cause of breakdowns.

The use of world-famous electric components such as OMRON, YASKAWA, Schneider (TE) and MEAN WELL greatly reduces the failure rate of the electric control system and improves the work efficiency of the users.

Besides, there are also electric safety devices like anemoscopes and obstacle lights and mechanical safety devices to prevent the breaking of trolley axles and wire ropes.
