A hand truck particularly adapted for the movement of extremely heavy barrels has a wheeled base platform to which is pivotally attached a barrel holding frame having a forward vertical position and a braced reclining position against the truck. The barrel frame has its pivot point located at a sufficiently forward and low position so as to achieve approximately a ninety to one lever arm from the truck handle to the pivot point. The barrel frame has two lower barrel holding hooks. A pivoted barrel grasper, a lever arm having a pair of offset, facing grabber hooks, is positioned by means of a moveable pivot pin so as to engage the top lip of a barrel. In use, the barrel truck is moved in the erect position adjacent to a barrel; the grasper is positioned so that the grabber hooks enclose the upper rim of the barrel. A downward motion on the lift arm, over the extended lever arm provided clasps the edge of the barrel, lifting it slightly and permitting the bottom support hooks to be slid under the bottom edge of the barrel. The lifting lever arm is then released and a sliding barrel lock hook locks the upper edge of the barrel to the barrel frame. The frame and barrel then may be tilted to a moving position; the separate frame pivot axis creates a large lever arm a single individual, working against a practical handle height, may tilt over a barrel weighing to 1,500 pounds. The barrel frame, when tilted, is supported entirely upon the truck which may then be manipulated to move the barrel to a new location. No strength is required on the part of the individual to support the tilted barrel during the movement process.
