Beam warehouse racking, also known as pick-up rack, cargorack, and pallet rack, are the most widely used pallet rack, and are also highly versatile. The Beam warehouse rackis divided into several rows along the width direction of the warehouse, and there is a roadway for stacking cranes, forklifts or other handling machinery. Each row of shelves is divided into several columns along the longitudinal direction of the warehouse, and is divided into several in the vertical direction. The layers form a large number of cargo spaces and store the goods in pallets. Shelf beam load can be up to 4500KG per floor. Most of these shelves are accessed by forward-operated battery forklifts, counterbalanced battery forklifts, and three-way forklifts. When the shelf height is low, electric stackers can be used, and ultra-high warehouses can be used for stacking operations.
