ABSTRACT:
An improved wheeled hand cart assembly has a tiltable lifting platform associated with a trailing platform so that separate loads may be transported on each platform. The lifting cart structure comprises a generally conventional L-shaped configuration having a pair of wheels mounted on a common axis, for rolling the lifting cart about. The lifting cart is tiltable about the wheel axis to retain and transport a load. The trailing cart comprises a support platform having a forward end coupled to the lifting cart for pivoting about an axis parallel to the common axis of the wheels, a rearward end portion supported on a caster-like wheel assembly for rolling from place to place in coordination with the spaced-apart wheels and a locking assembly for locking the lifting cart in a tilted position relative to the trailing cart.
