Thanks to continuously adjustable shelves and handles, the trolleys are easily adapted to different needs. Shelf edges and end grids keep the cargo firmly in place. Shelves are adapted ro standard boxes (600x400 mm). There are three different wheels designs for maximum driving comfort. Four swivel wheels allow the trolley to roll in all directions. Two swivel and two fixed wheels provide optimum driving stability. And the alternative with a support wheel system (two wheels positioned centrally underneath the trolley), makes the trolley easy to turn even with a heavy load. The chassis is made of 22 mm shiny zinc-coated tubing. Shelves are 12 mm, reversible or detachable and durable laminated with a light grey finish.
