Four drive concepts have established themselves in the lift table market over the past two decades. Each of these concepts comes with its own advantages and disadvantages, which we will examine in detail in this article series.
In this article, you will get a brief overview of the arguments for and against the various types of lift tables. For a more detailed analysis of the respective drive concepts, we recommend reading the following articles:
Hydraulic lift tables
A hydraulic lift table uses a combination of an electric motor, a hydraulic pump and hydraulic cylinders as its drive system. The electric motor drives the hydraulic pump, which directs oil into the cylinders. As the cylinders extend, the lift table is raised. To lower the table, the hydraulic oil is released from the cylinders, causing the cylinders to retract and the lift table platform is lowered in a controlled manner.

Belt-driven lift tables
This type of lift table uses belts to generate the upward and downward movement of the platform. The belts are connected on one side to a shaft flanged to the gearbox and on the other side to a lift carriage.
By winding and unwinding the belts on the shaft, the lift carriage moves, which in turn influences the position of the scissor mechanism, thus determining the lift height of the table.

Chain-driven lift tables
In this design, a push chain acts directly on the platform. When the chain extends, the platform is lifted, while retracting the chain causes a downward movement. The scissor mechanism here serves solely as lateral guidance.

Spindle lift tables
A lift table with a spindle drive operates with a load nut attached to one of the two scissor halves. The counterpart is located on the other scissor half. Similar to a screw-nut combination, the nut moves along the threaded rod when it is rotated.
