Lift tables can come in a vast array of configurations and can be built to suit various highly specialized industrial processes. For instance, they are often customized for integration into production lines, packaging systems, and automated warehouses. The most common lift table design incorporates hydraulic cylinders and an electrically ...

Hydraulic telescopic cylinders are often limited to a maximum hydraulic pressure of 2000-3000 psi. This is because the outward forces produced by internal hydraulic pressure tends to expand the steel sleeve sections. Too much pressure will cause the nested sleeves to balloon outward, bind the mechanism and stop moving.
A servo valve receives pressurized hydraulic fluid from a source, typically a hydraulic pump. It then transfers the fluid to a hydraulic cylinder in a closely controlled manner. Typically, the valve will move the spool proportionnaly to an electrical signal that it receives, indirectly controlling flow rate.
