The crossbeam rack is assembled by columns, crossbeams, cross braces, and slant support. Self locking bolts can be added to prevent the rack from losing stability when the bolts are loose; The height of each layer can be freely adjusted up and down with a step distance of 75mm. The span of the crossbeam shelving unit is generally within 4m, and the depth is within 1.5m. The height of the shelving in low and high level warehouses is generally within 12m, and the height of the shelving in ultra-high level warehouses is generally within 30m. The crossbeam generally adopts a specially cold-rolled P-type closed beam; This structure is simple, reliable, lightweight, strong in bearing capacity, and low in cost; The column clamp is equipped with a specially designed safety pin when connected to the column, ensuring that the crossbeam will not fall off under external impact (warehouse shelves). Components of a crossbeam style shelf: Column: Used to support the entire weight of the shelf; Beam: Connecting column pieces to support goods; Foot pieces: Connecting the shelf to the ground to make the shelf more stable; Anti collision guardrail: Protecting the shelf from forklift impact; Corner guard: Preventing moving cargo tools such as ground cows/forklifts from colliding; Column pieces; Connecting rods: Fixing back-to-back shelves; Crossbeam: Supporting goods to increase storage stability; Channel beam: Increasing overall stability of the shelf; Back stop beam/back net: Preventing pallets from exceeding the shelf; Barrier: Used to connect the shelf to the wall; Wooden board: Placing goods flat between the beams; Steel plate: Placing goods flat between the beams
