The following factors must be considered when selecting the right castor wheel for your application. Many factors together contribute in making a decision to select the most suitable castor wheel.
Depending on the type of application, swivel, fix or brake type castors can be used. One should also look at the installation fitting required for the castor. The castors come with top plate, thread pin, stem and bolt hole fittings.
The size of the wheel increases with the load. The possibility of overload, shock load and poor floor conditions require a safety factory to be included in the formula. The formula below enables load calculation over each castor wheel , considering some of the most important factors.
The formula below enables load calculation over each caster or wheel, considering some of the most important factors.
C = PE + PMC * S
C = Load per caster or wheel (kg),
Pe = Equipment, cart or structure weight (kg),
Pmc = Maximum load weight to be carried (kg),
N = Number of casters or wheels,
S = Safety coefficient
