Introduction of the Tower crane
I. The tower crane is a combination of advanced technologies of the present day. Its key parts use Q345 steel. Not only is the tower crane equipped with a hydraulic selfraising mechanism, but also its three key mechanisms (hoisting, slewing and radius-changing mechanisms) are all driven by frequency-converting motors.
II. 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.
III. The 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. Its Safety Monitoring System (also known as Black Box) displays the data of working radiuses, heights, moments and weights.
IV. 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.
V. There are also electric safety devices like anemoscopes and obstacle lights and mechanical safety devices to prevent the breaking of trolley axles and wireropes.
