What Are the Design Criteria for Warehouse Shelves?

General Principles of Designing and Planning Warehouse Storage Racks

• Increase the effective utilization of storage space;

• Facilitate the effective flow of goods, avoid cross-movement as much as possible;

• Simplification system principle, standardization of logistics.

Design Principles of Warehouse Storage Racks

The design principles of warehouse storage racksare mainly reflected in the warehouse rack, and the analysis and calculation of the load-bearing capacity of the warehouse rack is the focus of this technology. The design principles are mainly based on the following aspects:

• Live Load: Live load refers to the weight of goods and pallets placed on the warehouse rack, and also involves the snow (rain) load on the roof.

• Dead Load: Dead load refers to the weight of the warehouse rack structure itself, including the weight of the C-shaped steel and the wall frame, purlin, roof panel, and wall panel.

• Vertical Impact Load: Refers to the impact load generated when the stacker places goods.

• Wind Load: This is the focus of the overall three-dimensional warehouse's stress calculation. Generally speaking, investors of the overall three-dimensional warehouse start from the perspective of reasonable and effective use of space, so the height of the overall three-dimensional warehouse is high. Therefore, the safety of the warehouse under wind load is an important index. The calculation of the influence of wind load on warehouse storage racks' columns is generally completed through steel structure stress calculation software, and system force simulation and theoretical calculation should be used for review.

• Seismic Crack Resistance: Implemented according to the building seismic design code, generally the seismic crack resistance design level is set to level 7.

Considerations for selecting warehouse storage racks

The level of the warehouse's ground bearing capacity itself needs to be obtained from the builder. This parameter is very important. If your warehouse's ground bearing capacity is only 1 ton, and the rack's carrying capacity is 5 tons, the ground will inevitably sink or deform, and heavy objects may even collapse, causing safety accidents. Do not simply consider building high storage racks to save space, but also consider the basic weight of materials stored on high warehouse storage racks.

The type of materials carried and the container in which they are carried. The size of the rack needs to be related to the material or container that is being carried. The size can be customized, but it is best for the rack supplier to provide recommended sizes. On the one hand, it is relatively professional, and on the other hand, if there is a problem, part of the responsibility can be shared.

Loading and unloading equipment for the rack. Is there already equipment in place for placing the racks? If so, factors such as the equipment's turning radius and width need to be taken into account.

The form of the storage material's entry and exit, and the storage time. There may be materials with different storage times in the warehouse, which requires consideration of the form or storage method of entry and exit to find warehouse storage racksthat are truly suitable and can achieve high space utilization rate. For example, drive-in racks, adjustable pallet racks, rolling racks, mobile racks, and ordinary high storage racks. If these types of racks are selected, a certain amount of loading and unloading equipment, such as narrow-aisle forklifts, may also need to be invested.
