Hesterberg provides the commercial vehicle industry with numerous roof height adjustment systems under the name HESTAL LiftMaster. These are mainly used in curtainsider vehicles (trucks, trailers and swap bodies).

The LiftMaster is basically used for two reasons:

Firstly, to lift the vehicle roof for loading and unloading operations and to lower it afterwards. By this the entire cargo space can be used right up to the roof, because the required loading height is ensured by the lifted roof.

Secondly, to adjust the height of the vehicle roof to the required loading volume. On the one hand, the roof can be lifted and pegged for more space during transportation (under consideration of the total permitted vehicle height) or, on the other hand, lowered completely for efficient fuel consumption.

The HESTAL LiftMaster range consists of four different types which are interchangeable due to a modular design.

The LiftMaster 750N which is driven by a robust knee lever single lift mechanism is popularly used for lighter roofs with many loading and unloading operations, e.g. intercompany transportation. The integrated fall brake ensures a high level of safety for the user.

The proven LiftMaster 770N uses a knee lever mechanism patented by Hesterberg. The principle of operation employed enables a very easy, quick and variable roof lift.

LiftMaster 771N uses a compact hydraulic system that has already been proven in large-scale production. Thanks to the optimised hydraulics, this LiftMaster type is characterised by a very ergonomic and easy operation.

The hydropneumatic LiftMaster 855N is offered as a tailored solution. This type is especially used for very frequent lifting of heavy roofs. The automatic operation of the LiftMaster 855N is secured by a dead man‘s switch.
