II. Outstanding Features
1. The tower crane is a combination of advanced technologies of the
present day. It is equipped with a hydraulic self-raising
mechanismand 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 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.
4. 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.
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 wire ropes.
