Abstract

A caster wheel arrangement includes a base; a yoke rotatably mounted to the base via a kingpin; at least a first caster wheel rotatably mounted to the yoke; and an assist arrangement moveably mounted to the yoke. The assist arrangement facilitates travel of the caster wheel arrangement over a surface transition (e.g., a gap, a rise, etc.). Non-limiting example assist arrangements include a leading wheel, a leading variable radius wheel, a trailing wheel, a step member, and combinations thereof.
