Tower crane operating speeds include: Lifting speed, swing speed, varying speed, carts walking speed, and so on. In the lifting operation, lifting speed is the most important parameter, especially in high-rise buildings. If we increase the lifting speed, it can improve work efficiency.
When hanging objects , it need to get back its original place slowly, because lifting speed range is the presence of the lifting performance. The lifting speed id not only related with the lifting structure, but also with the hook pulley block ratio. Two ropes is faster than four ropes and single rope is faster than double ropes. In the lifting operation, the slewing, luffing, walking carts, etc., which do not require excessive speed, but must be able to smooth starting and braking, to achieve stepless speed control, and frequency control is ideal.
