Abstract: A bushing guided caster assembly for a rolling 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.

Abstract: A docking station for a foldable rolling ladder. The docking station has a moveable sled traveling in slots formed therein. The sled has a grip for engaging a ladder. The folding rolling ladder has a rear vertical and a brace that travels up and down the vertical and is pivotably connected to treads of the ladder at an opposite end. The brace has a bracket to engage the grip of the docking station. When the vertical of the ladder engages the sled, via the grip, causes the ladder to be folded into a storage position by the sled traveling within the docking station within and by the docking station and unfolded into a use position.
