ABSTRACT:
A hand truck comprises a frame having upper and lower frame parts which can be pivoted between folded and unfolded positions. Pivotable locks retain the frame parts in both such positions. A pair of wheel braces are attached to the lower frame part for rotation between folded and unfolded positions. A carrier member is mounted to the lower frame part for rotation between folded and unfolded positions. The carrier member locks the wheel braces in their unfolded positions. The wheel braces carry tires which frictionally engage the carrier member to retain the wheel braces in their folded positions. The portion of the lower frame part which carries the wheel braces and carrier member can be separated from the lower frame part and then rotated ninety degrees before being reattached to the lower frame part in a stored condition.
