How to choose the right wheel?
1. Select the wheel material: first consider the size of the road surface, obstacles, and the use of residual substances (such as iron scraps, grease) on the site.
Depending on the conditions of the environment (such as high temperature, normal temperature or low temperature) and the weight of the wheels, the suitable wheel material can be selected. For example,
Rubber wheel can not resist acid, grease and chemical, super polyurethane wheel, high strength polyurethane wheel, nylon wheel, steel wheel and high temperature wheel are suitable.
For different special environments.
2. Calculate the carrying weight: in order to be able to calculate the load capacity required by various casters, it is necessary to know that the transportation equipment is heavy and heavy.
The number of single and casters used. The load capacity required for a single wheel or caster is as follows:
T = (E + Z)/M (N:
-- -t = the load weight required for a single wheel or caster;
-- -e = the weight of the transport equipment;
-- -z = maximum load;
-M= the number of single and casters used;
-- -n = safety factor (about 1.3-1.5).
3. Determine the size of wheel diameter: the larger the diameter of the wheel caster is, the easier it is to drive, and the greater the load capacity is, the more it can protect the ground from damage.
The selection of wheel diameter should first consider the load bearing weight and the starting thrust of the carrying vehicle.
