ABSTRACT:
A hand truck construction comprising a wheeled, upright frame having at its lower end a load-supporting nose member swingable between raised and lowered positions. The nose member is spring biased to its raised position and the frame and the nose member are provided with a releasable latch mechanism for releasably latching the nose member in its lowered operative, load bearing position. Flexible, reinforcing cables extend between the frame and the nose member to maintain the latter substantially normal to the frame under heavy loads, the connection of the cables being such as to assure movement of the cables to positions inwardly of the sides of the frame in response to movement of the nose member to its raised position, thereby enabling the cables at all times to be maintained within the confines of the frame.
