Since the change of the lifting speed is too large when the pneumatic lifting equipment is used to lift different weights, an intelligent pressure regulating system was designed which could adjust pressure according to the lifting weight.A positive feedback element was added to the control system so that it could effectively guarantee the consistency of the lifting speed, reduce the springback phenomenon when weights was stopped suddenly. So the controllability of pneumatic lifting equipment is improved.
