How to adjust the lifting speed of a fixed scissors lift?

To adjust the lifting speed of a fixed scissor lift, you can modify certain hydraulic and electrical parameters, depending on the lift's design. Here are the main methods:
1.Adjusting the Hydraulic Flow Rate of Scissor Lift Table
Component:Hydraulic flow control valve or throttle valve
How it works:Slowing or increasing the oil flow rate to the cylinder changes lifting speed of stationary scissor lift.
How to adjust:
Locate the flow control valve on the hydraulic circuit (often near the pump or cylinder).
Turn the knob or screw clockwise to reduce flow (slower lift), or counterclockwise to increase flow (faster lift).
Make small adjustments, and test after each one.
2.Changing the Motor Speed of Scissor Table Lift
Component:Electric motor or motor controller (e.g., VFD)
How it works:A higher-speed motor pumps hydraulic oil faster, increasing lift speed.
How to adjust:If the motor is connected to a Variable Frequency Drive (VFD), adjust the frequency setting to increase/decrease motor speed.
For fixed-speed motors, replacement with a higher/lower RPM motor may be required.
3.Upgrading the Hydraulic Pump
Component:Hydraulic pump
How it works:A pump with a higher flow rate delivers oil faster to the cylinders.
Note:This requires careful system analysis - too much flow can exceed cylinder capacity or cause jerky movement.
Caution:
Never exceed the rated capacity or design specifications of the lift when adjusting speed.
Sudden changes in speed can affect safety and cause instability.
