Hydraulic dock leveller with telescopic lip

The PT2 stationary dock leveller with telescopic lip is a new product of PROMStahl’s wide product range. This top-quality product benefits from over 25 years of experience in the field of design and manufacture of docking technology. The hydraulic version of the PT leveller is operated at the touch of a button and after exact positioning of the telescopic lip automatically follows the movements of the vehicle during the loading or unloading process (automatic floating position). The big advantage of this type of dock leveller is the maximum flexibility of the lip length. Thanks to this feature effective loading and unloading even of vehicles that are not completely correctly positioned can be guaranteed and time-consuming and complicated repositioning of the vehicle is not necessary.

More informations

The PT2 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 type of installation. Alternative frame types are available depending on the individual building situation. The load capacity corresponds to the axle load limit taking into consideration the most unfavourable loading case.

The PROMStahl dock levellers meet all requirements of the European standard Norm EN 1398 and has passed the GS safety tests.
