The mobile racking / shelving systems are semi-automated systems which consist of racking or shelving mounted on mobile bases that slide along rails, set into the floor. Thanks to a motorized mechanism, the mobile basis can be moved as necessary to allow access to the stored materials in the individual aisle in question only. Available in two versions, Cargo for heavy loads and Light for more lightweight material, they can be moved manually, mechanically using a handwheel or electronically.
