The trolley casters is the caster used under the trolley, and it is also an industrial caster. Usually four casters are used, but how should the weight of these four casters be calculated? Is it the total load-weight divided by four? The Huanxin Hospital Bed Wheels caster manufacturer will introduce to you how to calculate the load bearing of the four casters of the trolley:

1. Not Total Weight Divided by 4

Because in some cases, only three casters are touching the ground at the same time, and one trolley caster is Hanging in the air and has no load bearing, so the total load is divided by three to get the load capacity of each trolley caster.

2. There is also a load margin factor

The total load capacity needs to have a margin coefficient, such as a coefficient of 1.2, which means that under the total load capacity requirement, multiplying by 1.2 is used as the total load capacity, leaving a load of 0.2 as a possible overload situation, but it is not It is said that the overload will be broken to 1.2, but it is only said that it is used under the load multiplied by 1.2, which is usually no problem, and the recommendation is to use it normally according to the normal total load of 1.0.

3. Refer to the calculation method of industrial caster load bearing

Not all trolleys have four casters, there may be more than one, and there may also be swivel casters and directional casters.

In short, through the above introduction, it should be clear how to calculate the load-bearing capacity of the four casters of the trolley. The load capacity of a single caster = total load capacity * 1.2 (the margin factor can be changed according to the situation) / 3 (considering that one of the casters is Hanging in the air state).
