ABSTRACT:
An auxiliary wheel set adapted for aftermarket installation on two-wheeled hand trucks. The apparatus includes a right vertical support and left vertical support, each having a leg portion with an upper section and a lower end, and a shoulder at its upper portion from which an upper arm extends outwardly substantially perpendicular to the leg. Each upper arm terminates in a curved elbow which connects the upper arm to a lower arm which extends inwardly and substantially parallel to the upper arm. A spreader bar is welded between the vertical supports to provide bracing. Locking caster wheels are disposed on the respective lower ends of the legs. The lower arms are journalled in bushings, which are, in turn, removably installed onto the side rails of a hand truck with U-bolts attached to first and second integral pivot plates. The wheel set selectively pivots between a stored position and a deployed position.
