The lifting speed method of the bridge crane is the speed at which the motor of the lifting mechanism raises the heavy object at the rated speed, that is, the lifting speed. Generally, the lifting speed does not exceed 30m / min, which is determined according to the nature of heavy objects, weight, and lifting requirements.
The lifting speed is also the air hook speed. The air hook speed can shorten the non-production time, and the air hook speed can be up to twice the rated lifting speed.
There is another special case of the lifting speed. The low speed when the heavy object is close to the ground is called landing low speed to ensure the safety of people and cargo. The speed is generally 4 ~ 6m / min.
