Calculate the load of a single caster to give a certain insurance factor, in the ground is relatively flat, a single caster load = (total weight of the equipment + the number of mounted casters) X 1.2 (insurance factor); if the ground is not flat, the algorithm is, a single caster load = total weight of the equipment +3, because regardless of which non-flat ground, there are always at least three wheels at the same time to support the equipment this algorithm is equivalent to increase the insurance factor, more This algorithm is equivalent to increase the insurance factor, more reliable, to prevent insufficient load-bearing, resulting in a significant reduction in the life of the casters or lead to accidents.
