Basic constructions of the tail lift
Tail lifts are divided into two types of lift constructions: The first is the parallel arm lift construction, where the mechanics of the tail lift are based on the principle of the parallelogram and raising and lowering are achieved entirely hydraulically.
Parallellogram lift construction
There are two types of lift constructions
- Rear-closing tail lift
- Slider lift (slide-under tail lift)
Angle adjustment, tilt up and tilt down
For tail lifts there are three different ways to adjust the platform angle.
Drive with a hydraulic cylinder
The double-acting cylinder retracts and extends the tail lift. The stroke of this cylinder corresponds to the slide-under length. The downside of this is that the cylinder is mounted far back under the cargo body, often in a hard-to-reach area above the axles.
Drive with a hydraulic motor
The biggest advantage of drive with a hydraulic motor is the direct power transfer at the two mounting plates, resulting in smooth, controlled movement, which is something that drive with a hydraulic cylinder cannot provide.
