L46A1 Mast Section Operation speed of tower crane, lifting, luffing, slewing and traveling speed control
The maximum rated lifting component corresponding to each stable operating speed gear, and the lifting speed under stable active state during the lifting hook recovery process. The lifting speed is not only related to the lifting mechanism, but also to the ratio of the hook pulley block. The ratio of 2 times is twice as fast as that of 4 times. In the lifting operation, especially in the construction of high-rise buildings, improving the lifting speed can improve the work efficiency, but it needs to be slow in place.

Luffing speed of tower crane trolley
For the trolley luffing tower crane, the rated lifting capacity at the maximum lifting capacity and the stable running speed of the trolley when the wind speed is less than 3m / s.
Slewing speed of tower crane
The stable rotation speed of tower crane when the hook is at the maximum height when the maximum additional lifting moment load condition and wind speed is less than 3m / s.
Traveling speed of tower crane
When the wind speed is less than 3m / s and the boom is parallel to the track direction, the speed of the tower crane running stably.
