Features of building internal climbing 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 self-raising 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 wire ropes.
