In general, hand trucks are heavy metal devices which are somewhat expensive and difficult to manipulate. A simple, readily portable, collapsible hand truck includes a tubular rectangular frame, the corners of which are interconnected by similar pairs of upper and lower, inverted L-shaped brackets, the upper brackets pivotally supporting a tubular, generally C-shaped handle and the lower brackets pivotally supporting a tubular, generally C-shaped load supporting platform; a pair of bifurcated yokes rotatably mounted on the frame sides above the lower brackets for supporting a pair of wheels; and a crossbar pivotally mounted on the inner end of the axle of one wheel for rotation from a vertical storage position to a horizontal use position engaging the yoke carrying the other wheel, whereby the yokes and wheels can be releasably latched in the parallel use position perpendicular to the frame.
