Dynamic load capacity
The load capacity listed for a wheel or castor is the load capacity which that wheel or castor was capable of withstanding when tested on a rotating bench in accordance with DIN EN 12527–12533 (ISO 22878–22884).
In order to determine the load capacity that a wheel or castor needs to have, it is important to know the dead weight of the transport equipment, the maximum additional weight and the number of supporting wheels or castors. When using four or more wheels or castors, the load on each individual wheel or castor may vary. The necessary load capacity is calculated as follows:
|Transport||Environment||Height of the obstacle||Safety factor|
|manual||indoors||< 5 % of wheel Ø||
|manual||outdoors||> 5 % of wheel Ø||1.5–2.2|
||indoors||< 5 % of wheel Ø||1.4–2.0|
||outdoors||> 5 % of wheel Ø||2.0–3.0|
Static load capacity
If a wheel or castor is exposed to mainly static loads, its static load capacity is tested in accordance with ISO 22878. One of the criteria that this test looks at is the extent to which the tread flattens after a specific period.
