Abstract
A one-piece caster and leveler assembly to aid in the transportation and installation of equipment that combines a leveler with a rotable foot and a wheel chassis. During movement of the equipment, the leveler may be placed in a retracted position where the rotable foot contacts and pitches away from the wheels, and rotates as the direction of movement changes, providing improved clearance, load capacity and tolerance for striking obstacles.
