Stationary drawbridge leveller with aluminium segments
The PPFA stationary drawbridge leveller is a new product of PROMStahl’s wide product range. It is suited for internal as well as for external docks and is used if small or medium differences in height between the dock edge and the lorry bed are to be compensated for. The drawbridge leveller is fixed to the ramp head by means of a steel hinge; for the loading or unloading process it is lowered onto the lorry bed by means of an operating rod. The leveller’s weight is compensated for by means of pressure springs so that the PPFA can be operated without any problems by one person only. For a nominal width and a nominal length of 2000 mm the drawbridge leveller is always equipped with 2 operating rods to allow operation by two persons.
When not in use the leveller is fixed in vertical position at the ramp edge and locked in this position by means of an automatic safety device. The PPFA version is equipped with a segmented aluminium lip to guarantee an optimal adaptation to vehicles that are not perfectly docked in. All steel parts of the PPFA leveller are available hot-dip galvanized.
The PROMStahl drawbridge leveller meets the requirements of the most recent European standard EN 1398.
