Feature of tower crane
1.Suitable for all kinds of construction project and can work under all kinds of work condition.
2.It has high working speed, good speed-adjusting performance, steady operation and high efficiency.
3.The crane has complete set of safety devices, which can guarantee the safe and high efficient operation of the equipment.
4.Three-speed motor and mono-speed ratio decelerator are applied in the lifting structure, which enables heavy load low speed and light load high speed.
5.Planet gear decelerator is applied in the circumcise rating structure, together with moment-limiting hydraulic couple, which can realize high load capacity, steady starting and reliable operation.
Safety features
Full set of safety protection equipment:weight limit,moment limit,height limit, and slewing limit,emergency brake, labor protective devices like rest platform and guardrail.
1.Weight limit: If the material is over the capacity, the crane will give a sharp warning for protection itself.
2.Moment limiter:Real-time monitoring and detection of crane working conditions, with its own diagnostic function, rapid dangerous status alarm and safety control.
3.Height limit:Control the lowest and highest extreme position of lifting hook.
4.Slewing limit: Control the extreme turns number of turn left and right.
5.Emergency brake: If the operation staff encounter some emergency situation, we could start the emergency brake system to protection the related treasure.
Advantage of Tower Crane
1.Robot automatic welding system;
2.Automatic impeller blasting and spraying assembly line;
3.CNC plasma cutting machine;
4.Precision machine tools;
5. France Schneider contactor;
