What factors should be considered in the design of narrow aisle shelves 1. Warehouse basic conditions: Consider warehouse length/width/clear height (reserved for fire and lighting space), ground flatness and load-bearing capacity, column/load-bearing wall position, to avoid shelf layout conflicts. 2. Goods attributes: Determine the specifications of the cargo space based on the size and weight of the cargo pallet, allocate the height of the cargo space according to the turnover frequency (high-frequency placement in the middle layer), and when "first in, first out" is required, shuttle board design can be used. 3. Equipment adaptation: Match the turning radius, body width, and lifting height of narrow aisle forklifts (three-way stacking/pedestrian upward type) to determine the aisle width (1.6-2.2 meters) and cargo space clearance. 4. Safety compliance: Install column foot guards, crossbeam locks, and top tie rods to ensure structural safety, reserve fire exits, lighting and ventilation spaces, and comply with industry standards for shelf design. 5. Operations and Expansion: Clear labeling and numbering of storage locations to adapt to inventory management, adjustable holes in columns for later adjustments, reserved maintenance space and spare areas to cope with business growth.
