Sliding cylinder drive
The double-acting sliding cylinder operates the extension and retraction of the tail lift. Its stroke corresponds to the required length of the extendable part. One challenge is that this cylinder is often mounted under the tail lift, usually in a difficult-to-reach location above the axles.
Double sliding cylinder
The double sliding cylinder consists of two cylinders placed side by side, connected in parallel, with a combined stroke length. However, in this configuration, the pressure and tensile forces are not aligned with the movement of the valve. This can lead to the lift becoming skewed during sliding, causing shaking and jerking. Wear and contamination of the sliding pipes, blocks, and bearings, as well as rust and sand, can exacerbate this effect.
