A hand truck for moving water heaters and toilets has a fixed frame with one or more fulcrum wheels on a rear side, at least one floor stabilizing arm coupled to and extending from a front side, at least one outrigger support beam extending from the rear of the fixed frame, the at least one outrigger support beam further comprising a wheel at a distal end; and an extendable frame having a vertical beam, a horizontal beam coupled to the top of the vertical beam, and at least one lifting arm extending perpendicularly to the horizontal beam; the extendable frame vertically adjustable in relation to the fixed frame.

1. A hand truck, comprising: a fixed frame comprising one or more fulcrum wheels on a rear side, at least one floor stabilizing arm coupled to and extending from a front side, at least one outrigger support beam extending from the rear of the fixed frame, the at least one outrigger support beam furt
1. A hand truck, comprising: a fixed frame comprising one or more fulcrum wheels on a rear side, at least one floor stabilizing arm coupled to and extending from a front side, at least one outrigger support beam extending from the rear of the fixed frame, the at least one outrigger support beam further comprising a wheel at a distal end; andan extendable frame comprising a vertical beam, a horizontal beam coupled to the top of the vertical beam, and at least one lifting arm extending perpendicularly to the horizontal beam;the extendable frame vertically adjustable in relation to the fixed frame;the fixed frame further comprising a hand crank coupled to the rear of the fixed frame, the hand crank configured to rotate one or more gears, the gears configured to wind and unwind a strap, the strap pivoting on a strap support rod, wherein the strap support rod is positioned at the center of the fixed frame and above a ring, the ring secured to the extendable frame, such that rotation of the hand crank in a first direction winds the strap causing the ring to be pulled upward, thereby vertically extending the extendable frame, and wherein when the hand crank is rotated in a second direction, the strap unwinds, allowing the ring to follow gravity downward, which lowers the extendable frame. 2. The hand truck of claim 1, wherein the one or more lifting arms are horizontally adjustable and are configured, at a distal end, to couple to a water heater. 3. The hand truck of claim 2, wherein the one or more lifting arms are configured to couple to a toilet. 4. The hand truck of claim 1, wherein the at least one floor stabilizing bar is removably attachable. 5. A method of using the hand truck of claim 1 for moving a water heater, the method comprising: positioning the lifting arms over the water heater;actuating the hand crank to raise or lower the extendable frame such that the lifting arms engage the water heater;securing the lifting arms to the water heater;actuating the hand crank in a first direction so as to raise the extendable frame, thereby raising the water heater; andtransporting the water heater to the desired location. 6. The method of claim 5, wherein the fixed frame is pivoted rearwardly such that the outrigger support beams engage the ground, allowing the hand truck to fully-support the water heater. 7. A hand truck, comprising: a fixed frame comprising: one or more fulcrum wheels on a rear side;at least one floor stabilizing arm coupled to and extending from a front side; andat least one outrigger support beam extending from the rear of the fixed frame, the at least one outrigger support beam non-parallel to the fixed frame and further comprising a wheel at a distal end;an extendable frame comprising: a vertical beam;a horizontal beam coupled to the top of the vertical beam; anda pair of horizontally-adjustable lifting arms extending perpendicularly from the horizontal beam to engage the fittings on the top of a water heater;wherein the extendable frame is vertically adjustable in relation to the fixed frame.
