1, first select the appropriate body material of caster wheel:
first consider the caster wheel walk on what kind of ground, such as the road size, obstacles, residual material on the site (such as iron, oil), environmental conditions (such as high temperature, normal temperature or low temperature) and the weight caster wheels can carry. These various conditions determine the selection of material for caster wheels.
For example: rubber caster wheel will be corroded by acid, oil and chemicals, while super-polyurethane caster wheels, high-strength polyurethane caster wheels, nylon wheels, steel wheels are able to apply different special environment.
2, how to calculate the weight-bearing of swivel caster wheel: In order to calculate the load capacity of various caster wheels, we must know the weight of transport equipment, the largest single load and the number of wheels. The load capacity of single caster wheel is calculated as follows: T = (EZ) / M × N
In this formula, "T" represents weight-bearing of single caster wheel; "E" represents weight of transport equipment; “Z” represents maximum load; “M” represents the single number of wheel and castors; “N” represents safety factor (about 1.3-1.5).
3, set the diameter of caster wheels: usually, diameter of caster wheel is more greater so that the promotion is easier, the greater the load capacity but also better able to protect the surface from damage. The selection of caster wheel diameter should be first considered the load carrying weight and starting thrust from transport vehicles.
