Mekdrive 3 Compactus® is the lightest mechanically assisted mobile storage system available. It has been designed to keep floor loads to a minimum, a major consideration in commercial office buildings. The Mekdrive 3 Compactus® has an increased system width of four shelving bays, which could previously only be achieved with fixed-track systems. The Mekdrive 3 Compactus® provides incredible value and cost efficiencies when compared with traditional mechanically operated fixed-track systems.
