The majority of lift tables have an electro/hydraulic operating system. An electric lift motor drives a hydraulic pump which raises the lift table; the load is held in position when the motor activation is discontinued, activating a solenoid valve lowers the lift table.
The most common method to operate a lift table is with a hand held constant pressure push button control station. Depress and hold the UP button until the lift table is in the desired position, release of any buttons holds the lift table in its current position. Depress and hold the DOWN button to lower the lift table. https://www.pentalift.com/wp-content/uploads/2020/10/ProSeries.pdf
An alternative method to operate a lift table is a guarded foot pedal control; this option frees the operator’s hands. The guarded foot pedal control also has a constant pressure UP and Down switch for platform positioning. In applications that are automated it is common for a PLC to sequence the operation of the lift table.
Pneumatic lift tables are available and often used in applications where electrical controls are not desirable. As standard a manual control valve on a pedestal is supplied to operate the lift table, pull back on the valve handle to raise the lift table, push forward to lower the lift table. A guarded foot pedal is also available to operate the lift table freeing the operator’s hands. https://www.pentalift.com/wp-content/uploads/2020/10/L020.pdf
Self levelling lift tables are commonly used in palletizing or de-palletizing applications. A self levelling lift table stores in the raised position when empty, as weight is added the platform automatically lowers, as weight is removed the platform automatically raises; adding or removing weight operates a self levelling lift table. https://www.pentalift.com/solutions/pentaloader-automatic-self-leveling-palletizer-2/
