What are the methods to test the load capacity of industrial casters?

Update:2020-09-23

Determine the load-bearing capacity of a single industrial caster according to the design load. The load-bearing capacity of industrial casters is the most basic and most critical requirement for industrial casters, and the actual conditions of use are very different. Therefore, when selecting the load-bearing capacity of industrial casters, a certain safety margin should be left. The most commonly used Take four-wheel installation as an example, usually you can choose according to the following two methods:

Choose according to three industrial casters to bear all the weight. One of the industrial casters is suspended in the air. This method is suitable for occasions where the industrial casters bear high impulse and the ground conditions are poor during cargo shipment or equipment movement, especially when the total weight is large.

Choose 120% of the total weight of the four industrial casters. This method is suitable for occasions where the ground condition is good and the impact on industrial casters is small during cargo shipment or equipment movement. To

It should be particularly pointed out that for those industrial casters that will be greatly impacted, not only industrial casters with large load-bearing capacity should be selected, but also specially designed impact-resistant structures should be selected.

Determine the load-bearing capacity of a single caster according to the design load. The load-bearing capacity of industrial casters is the most basic and most critical requirement for casters, and the actual conditions of use are very different. Therefore, when the load-bearing capacity of casters is actually selected, a certain safety margin should be left.

It needs to be specially pointed out that for those industrial casters that may be subject to a great impact, not only casters with large load-bearing capacity should be selected, but also specially designed impact-resistant structures should be selected. To ensure that the casters are a general load that can carry out long-term handling in a safe state, it is necessary to estimate the total weight of the carried objects in advance, and then select the appropriate casters according to the allowed load.

In the actual use environment, it usually happens that only 3 of the 4 casters are under force. Therefore, the total weight limit should be based on the theoretical × safety factor of 0.8.

For example: when using 4 casters, the total weight limit = allowable load-bearing load of each caster*4*0.8. When casters of different sizes are used in combination, the caster with the lowest load-bearing load should be used as the basis to calculate the whole Maximum load. In order to be able to calculate the required load capacity of various casters, it is necessary to know the weight of the transport equipment, the maximum load and the number of wheels and casters used. The required load capacity of a single wheel or industrial caster is calculated as follows:


T=(E+Z)/M×NT=The required bearing weight of single wheel or industrial caster;
E = the weight of the transportation equipment; Z = the maximum load;
M = the number of single wheels and casters used; N = safety factor (about 1.3-1.5)
