Rated speed of a lift’s operation is determined by the type of actuation used, capacity and travel.  All lifts have a standard operating speed for raising and lowering the platform based on those design elements.  In some applications, there are times when it is necessary to modify the speed.  We offer simple and reliable solutions for modifying operating speeds for high and low power, industrial and precision lift applications.

Low Speed

Autoquip has customized lifts to travel at reduced and extremely low speed in applications requiring precise mating, or for a load that cannot tolerate quick raising or lowering speeds. 


Autoquip typically slows the speed of a hydraulic lift by adding flow control valves.


Autoquip can reduce the output speed on mechanical lifts by adjusting the motor horsepower and gearbox reducer to achieve the desired speed for the customer’s application.  If an exact raise or lowered speed is required, a mechanical actuated lift will prove to be the most precise.


Lower speeds can be achieved on pneumatic lifts by regulating the air pressure and we can do that by including an air pressure regulator or a flow control valve.


Higher Speed

Higher speed actuation is a more common request of a lift, as increased speed adds to productivity and potentially throughput of product in production.  When considering higher speed operation it may be good to consider options which will soften the shock of higher speeds. 


To increase the speed of raising a hydraulic lift we normally use a higher horse power electric motor or a higher volume fluid pump with a larger fluid reservoir.

Typically hydraulic lifts utilizes gravity to lower.  The lift simply vents the hydraulic fluid, at a controlled rate, allowing the weight of the lift and the package to lower the lift.  If higher or more consistent lowering speed is required Autoquip would add either a dual-acting cylinder to push the lift down or increase the flow of fluid being released.


High speed is achieved by an increase in horsepower or an upgrade to the gear box.


The raising speed of a pneumatic lift can be increased with added air pressure.  But there is no reasonable way to increase the lowering speed of a pneumatic lift.

Fixed Speed

Fixed speed applications using automation may require a more regimented speed of raising or lowering.


Fixed speed can be controlled by the flow rate the pump delivers during operation. The larger the amount of fluid returned to tank, the slower the lift goes.   Based upon the complexity of the application, sensors can be added to the lift for a more controlled fixed speed.


Fixed speed for mechanical actuation is achieved by adjusting the gear box.


For a precise volume flow, we offer flow controls and pressure regulators.  But pneumatic is the least precise method of fixing the raising speed of a lift.

Variable Speed

Variable speed control is important to those applications where process control is critical to the success of the operation. Applications requiring variable speed include:

  • A smooth operation & soft landing
  • Controlling lift acceleration and deceleration
  • A  slow start-up operation for set up
  • Accurate positioning

Autoquip can change the output of speed through variable speed controls on both hydraulic and mechanical actuated lifts. 


Variable speeds for a hydraulic lift system can be driven by varying the pump output or using a flow control valve.


Variable speed can be controlled on a mechanically actuated lift by utilizing a VFD (variable frequency drive).  The VFD allows speed to be controlled by varying the motor frequency.  The lower the frequency the slower the motor will turn.  The converse is also true, the higher the frequency the faster the motor will turn.
