Abstract: A hand truck assembly includes a lightweight body, such as is formed of a blow molded plastic material, in combination with a folding metal platen for supporting a load. The platen has a support area and a pair of mounting ears which extend upwardly from the support area. An axle extends through a transverse passage defined by the body, and the platen is pivotably mounted to the axle for movement between an inoperative raised position and an operative lowered position. A guide arrangement is interposed between the body and the platen for guiding movement of the platen between its operative lowered position and inoperative raised position. The body includes parallel rail sections which impart significant strength to the body. The body further includes an upper handle section having a forwardly directed handle, which provides ergonomically advantageous operation of the hand truck assembly.
