Where high flexibility is demanded during storage and retrieval, t he Jungheinrcihc pedestrian stacker, type ERC, is the ideal truck.  The problem-free folding-in and-out of the stand-on platform and side guards permits stand-on and pedestrian operation. A particularly economical method for rack servicing and transporting of loads over long distances.  Through an additional support arm lift, the ERC-Z  has an increased ground clearance of 4.6".  With this, floor irregularities, ramps, bridging plates, and loading bridges can be negotiated effortlessly, even with a full load.  The support arm lift operates separately from the mast lift.  When the forks reach a certain height during stacking and retrieval, the support arms automatically lower to provide continuous maximum stability.
