摘要： An improved caster assembly for moving heavy loads upon a caster platform. This caster assembly is less prone to breakage than conventional caster assemblies, and additionally incorporates a safety lid for reducing the risk if injury to workers. This caster assembly is comprised of a box frame member within which a caster wheel is rotatably mounted. The box frame member is coupled in an offset position to a rotatable platform, which allows the caster assembly to rotate with the direction of force applied to a load moving across a caster platform in which it is mounted. This caster assembly is designed to couple into cavities present in existing caster platforms. The safety lid serves to close any gaps present in these platform cavities, thereby reducing the likelihood of a worker's foot or hand becoming caught in the cavity and injured by an approaching heavy load.
