ABSTRACT:
A hand truck includes a bottom base, a reinforcing member, a positing device and a handle. The bottom base consists of a U-shaped tube and a bottom plate combined vertically with a lower end of the U-shaped tube, which has two elongate side vertical portions provided with a lengthwise center hole. The reinforcing member has two side vertical tubes and two lateral rods fixed between the two side vertical tubes, which fit tightly around an intermediate section of the two side vertical portions of the U-shaped for upgrading the strength of the U-shaped tube. The position device is to stabilize the handle at an adjusted position after moved up and down and adjusted in its height relative to the U-shaped tube.
