ABSTRACT:
A two-wheeled hand truck structure incorporates a primary frame, adapted in use to assume a vertically inclined position and having a forwardly projecting, load supporting, nose portion. The frame comprises an open framework with side rails connected by cross rails and at its upper end has a handle portion which can be grasped by the user to propel the truck. The cross rails comprise generally U-shaped plastic bars, each having a base wall portion, spaced apart opposing wall portions extending generally parallelly therefrom, and end wall portions integrally joining the base wall portion and opposing wall portions. Internal rib sections extend integrally from each base wall portion at angles one to another at spaced intervals over the length of the cross rails and integrally join with the opposing wall portions.
