Each pallet rack will hold a different amount of weight. The amount of weight they hold depend of a few factors; the sizes and types of load and upright beams, the configuration of the components and the type of pallet rack in question. The manufacturer of the pallet rack will know what the weight capacity of pallet rack is. Sometimes, pallet racks have a plate listing its weight limit that is visible but not always.
Wight Restrictions According To The Manufacturers Specifications
As required by the RMI (Rack Manufacturers Institute) each manufacturer must provide the load capacity of each of the pallet racks sold to the buyer of these racks. The RMI provides rack manufacturers will the formulas to calculate the maximum load capacity for the pallet racks along with strict standards for construction. These formulas take into account the different variables including wind, unbalanced loads, earthquake and building attachment. If the racks have multiple options of configurations, manufacturers must provide drawings of these load applications and configurations. Once the rack is sold, it is then the responsibility of the owner to attach the pallet rack’s weight limit plate in an area that is clearly visible. The plate must also include the load size and configuration information pertaining to that particular pallet rack.
Weight Capacity Depends On Configuration And Components
The load capacity of the various pallet racks will depend on the various types and sizes of vertical uprights as well as horizontal load beams. The load beams together with the configuration options make for a wide range of weight capacities. The owners of the pallet racks need to take into account the maximum weight limits drawn up by the manufacturer of the pallet rack, taking into account the configurations and components used in the set up.
Weight Restrictions As Per The Bay Capacity
The weight capacity for the bay is typically what is listed by the manufacturer according to the pallet rack size and configuration. This implication is vital to understand and adhere to. The bay capacity indicates to the entire weight that can be withstood between the 2 upright beams; it is not the weight allowed per upright, per level or per beam. The weight of the rack components is also included in the bay capacity total weight formula. The formula for calculating the amount of weight each horizontal level can tolerate is as follows; from the total weight, deduct the weight of the rack accessories and components then take the new weight amount and divide this amount by the amount of levels on the rack.
Weight Capacity Per Pallet Rack Type
Each type of pallet rack has a different weight capacity. A gravity flow rack will have a different weight rating from other types of racks including pushback, seismic, selective and drive-in racks (to mention only a few). The owner of pallet racking must consult the manufacturer and give the type, component size and configuration of the pallet rack to get the weight capacity of the pallet rack in question.
Other Factors Affecting Weight Capacity
Manufacturers base the weight capacity of the pallet racking using only evenly distributed loads in interior conditions. When used in business, if the load is not evenly distributed, this could make the load seem heavier than it actually is. Also, in business, locations that have a fair amount of seismic activity will have a different load capacity to a location that does not have. When purchasing and building pallet racking these factors need to be taken into account.
