In the process of racking warehouse selection, you need to ensure that the racking to the ground load needs to meet the requirements. How to accurately calculate it?
In general, the need to calculate the shelf on the ground load of the concentrated load and the average load.
1.Calculation method of concentrated load
Concentrated load is the concentrated force of each column on the ground, usually expressed in tons.
The figure intercepts one of the shelves adjacent to the arrangement of two compartments, each compartment to place two pallets of goods.
The weight of the two pallets of goods are equally apportioned to the 1, 2, 3, 4 columns above, so the weight of each column is apportioned D * 2 / 4 = 0.5D, and then we take the 3rd column as an example, in addition to the left side of the goods compartment, the 3rd column with the 4th, 5th, 6th together with an average apportionment of the right side of the compartment of the weight of the two trays, the method of calculation is the same as the left side of the compartment, the apportionment of the weight is 0.5D, the weight of a pallet. Therefore, the No. 3 column in this layer of the load can be simplified to the weight of a pallet. Then count the total number of shelves, with the weight of a single pallet multiplied by the number of layers is the concentrated load of the shelf column.
2.Calculation method of average load
The average load is calculated for the projected area of a particular cargo compartment:
In the projected area, each layer of shelves have two pallets of goods, plus the weight of the shelves themselves, then the average load can be used to two pallets of weight plus the weight of the two cargo shelves multiplied by the number of layers, and then divided by the projected area can be. Still in accordance with the unit of goods 700kg, shelves 9 layers as an example, the length of the projected area in the figure L by 2.4m, W by 1.2 meters.
The average load is: ((700 + 40)*2*9/1000)/(2.4*1.2)=4.625t/m²
Warehouse shelving selection is a professional work. we should be a comprehensive consideration of relevant factors, effective selection of the best type of shelving.
