Mechanical dock levellers

PPF PPFA - Stationary drawbridge leveller

Stationary drawbridge leveller PP is a new element of the PROM product line development. It is intended for external and internal docks and is used when small and medium height differences between the edge of the dock and the vehicle bed are to be bridged. The dock leveller is mounted on the dock head using a steel hinge and it is lowered onto the vehicle bed during loading/unloading process using the operating rod. Pressure springs compensate for the drawbridge weight so that the PP may be easily operated by only one person. Starting from the width of 2000 mm we recommend the use of two rods (levers) to enable operation two people. In the rest position the drawbridge is positioned vertically on the edge of the dock and it is fixed in this position by automatic fall protection.

PROM dock leveller meets the newest European standard EN 1398.

The PPFA model is equipped with a sectioned aluminum lip, which adapts to the width of the loading area (vehicle bed) and to the height difference between the level of the upper edge of the dock and the lower edge of the vehicle bed.

Allowable gradient angle
According to the EN 1398 standard, operating the dock leveller beyond the allowable gradient angle ± 12.5% (approximately ±7°) is not acceptable. The specified value can be exceeded only if the user prevents slip hazard (e.g. by maintaining clean and dry surfaces).
