Stretched Kingpin

This particular caster happened to be part of a paint line process. In some instances carts can be moved through a production process with a power-towed application. This can be either a chained system in the floor or some other automated system. In any type of automated solution utilizing casters and carts, the load put on the caster is usually much harsher than normal and requires a stronger raceway. Anytime that you are pulling a cart you have to be far more careful of the total load being exerted on the caster.
