132HC Mast Section Lifting speed of tower crane
The working speed of tower crane includes: lifting speed, turning speed, luffing speed, etc. In the lifting operation, the lifting speed of tower crane is the most important parameter, especially in high-rise buildings, improving the lifting speed can improve the working efficiency, and at the same time, the lifting objects need to be slow in place, so the wide range of lifting speed change is the performance of excellent lifting performance.

The hoisting speed is not only related to the hoisting mechanism, but also to the ratio of the hook pulley block. The hoisting speed of 2 rope is twice as fast as that of 4 rope, and that of single rope is twice as fast as that of 2 rope.
In the hoisting operation, the speed of rotation and luffing is not required to be too fast, but it must be able to start and brake smoothly, realize stepless speed regulation, and frequency conversion control is ideal.
