Load capacity of wheels and castors

Calculate the required load-bearing capacity of wheels and castors as follows:

T = maximum load capacity of a castor

G = total weight of transport device (dead weight + max. load)

R = all assembled castors 

T = G / (R x 0,75)

What is certain is that there is no application where all the conditions (ie slippery road surface, walking speed, even load on all rollers) are optimally met at all times. Therefore, the number of rolls is multiplied by a factor of 0.75, which means that a security deposit of 25% is taken into account.

The information on castors-direct.com is dynamic load capacity according to DIN EN 12530, 12532, 12533.

Load capacity is one of the most important factors when choosing the best wheels and castors. The measurements of the load capacities of wheels and castors from rollen-direkt.de are based on the test method of the rotary disc test stand (DIN EN 12527).

The tests meet the following conditions:

- Speed 4 km/h

- Temperature 15° to 25°C.

- Obstacles 5% of the wheel diameter (at <91° Shore A)

- Obstacles 2% of the wheel diameter (at >91° Shore A)

- Driving distance 15,000 x wheel circumference

In addition, we test all wheels on drum test benches. With which we test the maximum continuous load, including various environmental influences, in long-term tests. Thus, the greatest possible safety and quality is guaranteed in advance.
