Mobile storage systems (Compactors) are moveable filing cabinets mounted on a track way. These specialized office furniture units are usually constructed with a rotary handle on the exterior accessible face. When revolved, the handle operates the mechanism which winds the single, connected, filing unit either left or right, depending on a clockwise or counter clockwise rotation of the handle.
By eliminating the need for an aisle between every shelving unit, more floor space can be utilized for storage. The tracks are leveled to eliminate gradients in the supporting floor. This makes it possible to move heavy units with minimal effort.
