A framework structure is formed by multiple column pieces and stable connecting rods. The fixed arm and the movable arm are assembled on each column piece.
Multiple movable arm groups form a support structure to store materials in a three-dimensional manner. As the name suggests, it makes use of the height space to convert the flat storage on the ground into a three-dimensional storage in a multi-layered stacking. Three-dimensional storage can maximize the utilization of space height, greatly improving storage efficiency, reducing storage area, and significantly lowering storage costs. The telescopic cantilever frame solves the original old stacking scheme through a multi-layer structure, thereby addressing the issues of storage efficiency and storage costs.
