Loading and unloading of goods can be done manually or by forklifts. The height of cantilever racking is usually lower than 2500mm (the height up to 6000mm by using forklifts for loading); length of arm is shorter than 1500mm, and loading capacity is no more than 500kg per arm. Cantilever racking is mainly used in the Mechanical Manufacturing Industry and markets for building materials.
