Abstract
A hand truck with a load carrying nose plate usable as a two-wheeled product transporter, and alternatively as a carrier for a fabric receptacle has a two-wheel supported frame assembly mounting a nose plate to project generally perpendicularly. A support assembly connected to the base end of the main frame assembly provides an extension projecting parallelly outwardly beyond the nose plate. A generally rigid receptacle suspension frame system from which the fabric receptacle depends has a device thereon for demountably supporting the outer end of the suspension frame system and a support part on the main frame assembly demountably interfits with and carries the opposite inner end of the suspension frame system. The hand truck in several versions is a convertible hand truck usable in four-wheeled as well as two-wheeled configuration.
