Advantages
As a combination of the latest technologies, the tower crane is equipped with a variable frequency slewing device and a wide variety of reliable safety devices, such as the hoisting height limiter, slewing range limiter, and multifunctional limiter offering great help to control the load moment, hoisting capacity and trolley moving range. In addition, 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.

The electric control system of our tower crane adopts the advanced PLC (Programmable Logic Controller) with frequency converter that realizes variable speed regulation and enhances the reliability, maneuverability and stability of the control system. Also, the work efficiency of tower crane is improved. The PLC unit can diagnose the cause of breakdowns.

Our hydraulic crane is equipped with electrical components introduced from world-renowned suppliers like OMRON, YASKAWA, Schneider (TE) and MEAN WELL to decrease the failure rate of the electric control system and increase the working efficiency.
