HYBRID MATERIAL ROLLING LADDER WITH LIFT ASSIST LOCKSTEP AND GAS SPRING CASTERS
A bushing guided caster assembly for a hybrid material ladder. The caster assembly has an outer housing in which an inner tubular slide slides within the outer housing on bushings. A caster is attached to the inner slide. A gas spring is formed in the inner tubular slide such that the inner slide slides up within the housing as an increasing force is applied downwardly on the housing until the inner tubular slide has traveled a preselected distance until the fixed ladder feet contact the floor or surface upon which the ladder is supported.
