Edge Of Dock MDLM MECHANICAL SERIES DOCK Leveler MINIDOK MDLM mechanical series dock leveler Minidock is an efficient and economical device designed for using with trucks which have approximately the same height above the ramp level. It does not require a power supply and can be used when it is impossible to install an electro hydraulic dock leveler. Minidock can be operated manually by one person with a special lever. When the upper deck is raised the lip turns and opens automatically. Then the deck lowers until it rests on the truck bed. After loading/unloading is completed, the lip lowers; the deck rises and returns to its rest position. Dock leveler can be installed either on the ramp or in the pit (optionally).
