ASSA ABLOY DL6220ST Stepdock Leveller

The ASSA ABLOY DL6220ST stepdock is a dock leveler that provides increased efficiency and safety for the docking process. Unlike conventional docking systems, the dock leveler is placed behind a well-insulated sectional door. In closed position, it is very well sealed off from below, preventing cold or hot air access. The design was specifically developed to let a truck dock to the loading bay with closed rear doors. First the truck is put in the right position and then preferably an inflatable dock shelter seals off the loading bay before the sectional door is opened. The last step of the complete dock-in procedure is that the rear doors of the truck are opened. This sequence "dock first – open the rear doors later" provides a number of benefits: saving of energy, improving working conditions in particular for the truck driver, increasing safety of people / goods, and improving the efficiency of the docking process.
