QTZ80(5513)construction tower crane

All of construction tower cranes are incorporated with internationally advanced "Tower Crane Computerized Design Platform(TCDP)" optimized design,featuring in advanced mechanism, uniform load bearing,good appearance,superior performance and complete,reliable safety devices.

1.The tower crane is a combination of advanced technologies of the present day. It is equipped with a hydraulic self-raising mechanism and afrequency-converting slewing mechanism.

2.The electric control system of the tower crane adopts the advanced "PLC + frequency converter" control mode of the present day, which has realized the stepless speed regulation and greatly improves the reliability, maneuverability and stability of the control system and the work efficiency of the tower crane.

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

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

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