The Crawford 6020STA Stepdock Autodock from ASSA ABLOY Entrance Systems is a dock leveller that provides increased efficiency and safety for the docking process. The leveller is 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.
