How is the dynamic load capacity calculated?
T = (E + Z) / (n-1)
E = Dead weight of the equipment
Z = Payload
n = Number of castors or wheels
In this calculation, the number of castors or wheels is reduced by one. This is because transport equipment is seldom used on perfectly even floors. Often, the load is not distributed to all of the castors or wheels at the same time. In order to take this into account, the load capacity calculation is designed to cover these cases too.
Important factors for the dynamic load capacity
The calculation is based on standard conditions, i.e. moving straight ahead on level floors at walking speed with uniform load distribution and a moderate ambient temperature (15°C to 28°C). If the actual conditions deviate from these, the load capacity will change. The actual conditions must therefore be taken into account from the start. For heavy-duty castors that can carry particularly heavy loads, it is also important to add a safety factor to the formula: the greater the load, the greater the safety factor.
