Loads on wheels and castors

Drop & impact loads on wheels and castors

Falling and impact loads can have destructive effects on wheels and castors. It is therefore important to calculate certain eventualities in advance.

For example, uneven floors, edges or floor transitions can lead to temporary overloading of the moving wheels and castors. Likewise, falling loads or the setting down of the transport device by a forklift have a direct effect on the wheels or rollers. If these forces are not taken into account when selecting the castor, this can cause deformation or breakage of the components during use.

The following options exist to counteract these risks, which are difficult to calculate:

increase wheel diameter

Increase load capacity reserves

increase damping capacity

Example:

Swivel castor with plate attachment

wheel diameter 150 mm,

load capacity 450 kg,

Shore hardness 90° A (hard)

not elastic (little cushioning)

You are planning to exhaust the load limit and your floor has significant unevenness, greater than or equal to 5% of the wheel diameter 150 mm or you are transporting on mixed floor conditions.

For safety reasons, it is advisable to choose a series with a softer wheel bandage and a larger wheel diameter.

Our recommendation:

Swivel castor with plate attachment

Wheel diameter 160mm

Load capacity 500 kg

Shore hardness 75° A (soft to medium hard)

slightly elastic (good cushioning)

Loads from lateral forces

Lateral forces can occur in different ways. To name a few examples: lateral pressure on the transport device, direct action on the roller height, for example by a loaded pallet truck, or even the tilting of a transport device triggers transverse forces.

When lateral forces occur, a stable wheel and a stable fork head in the housing are very important. Rollers from rollen-direkt.de are built to be robust and stable due to their construction. Therefore are

Damage caused by lateral forces has very rarely been an issue up until now.

In the field of replacement rolls, old rolls against rolls from rollen-direkt.de, we encounter this topic a little more frequently. In doing so, we find again and again that the transverse forces were not considered. Accordingly, the user has advocated inexpensive, qualitatively disadvantaged wheels and castors that are not up to lateral forces.

The high processing quality of rollers from rollen-direkt.de ensures that the occasional occurrence of short-term lateral forces does not result in a total loss. In principle, even with our quality level, the fewer lateral forces that act, the longer the service life of the wheels and castors.
