Specifications
Professional manufacture of construction machine, have CE,ISO,GOST approve, high quality and low price.
The tower crane is a combination of advanced technologies of the present day. It is equipped with a
hydraulic self-raising mechanism and a frequency-converting slewing mechanism.
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.
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.
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.
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.
