ESS, an ideal solution to ensure the safety of the docking process, the safety of the goods and the driver who does not have to leave the vehicle directly in front of the bay to open the rear of the trailer. An additional advantage of the system is the significant reduction in costs associated with the loss of energy needed to heat or cool warehouses during loading, as the door opens after the vehicle is docked and sealed. The AMTRV-ESS dock leveller is not only used for internal loading docks, but also for specially developed external loading bays with doors and air seals, ideally suited to solutions applied in freezers.
