Abstract

A portable hand truck is disclosed having a collapsible frame, the frame being movable between collapsed, storage mode and an expanded, upright mode. The hand truck has wheels disposed at a lower end of the frame, a folding support platform hingedly or rotatably connected to a lower end of the frame, and having a battery, a drive controller, and at least one motor. The motor is mechanically connected to at least one wheel or to an axle of the hand truck, and the motor is electrically connected to the battery and the drive controller. The motor and battery are positioned on a lower part of the frame of the hand truck, proximate the wheels to provide a more compact area for collapsing the frame, as well as to provide a lower center of gravity for the hand truck, thereby making the hand truck more stable.
