Type PSS

Stationary dock leveller with hinge lip and Fall Guard lock

The PSS-type dock leveller with hinge lip and Fall Guard safety device is a new design in the wide range of PROMStahl products which has been designed to provide optimal safety for the loading house staff. The rapid pace of work involving handling systems in storage places or warehouses can lead to many dangerous and even life-threatening accidents with fork lift trucks. That is why the PSS-type dock leveller is equipped with the Fall Guard safety device. When the dock leveller is in its rest position, a 90 mm section of hinge lip is raised vertically above the platform surface, thus creating an obstacle and preventing the fork lift truck and the warehouse personnel from falling from the ramp.

More informations

The PSS-type electro-hydraulic dock leveller is operated at the touch of a button. As soon as the platform has reached its highest position the lip swings out automatically and comes to rest on the lorry bed. During loading and unloading the PROMStahl dock leveller follows the movements of the vehicle (automatic fl oating position). The PSS-type dock leveller is supplied including frame and installed in the pit as a compact unit in just one step. Additional supports are not necessary. Considerable savings in installation and its tail-lift recess, i.e. the possibility to accommodate tail lifts, are the big advantages of this system. The load capacity of the PSS-type dock leveller meets the forklift axle load requirements, including worst case load situations.

The PROMStahl PSS-type dock leveller meets the requirements of the most recent European Standard, EN 1398, and carries the CE marking. Additionally, it has been voluntarily certifi ed by the globally-recognized German Technical Inspection Association TÜV and received the GS mark.
