This Milwaukee heavy-duty Aluminum Convertible truck has a foot latch that quickly and easily converts from a 2 wheel vertical truck to a 4 wheel platform cart in the horizontal position. No hitch pins required. The Aluminum is lighter than steel but yet this truck has an 800-Pound load capacity in the vertical position and 1000-Pound in the horizontal position. 10-Inch pneumatic tires cushion the load and allow the truck to roll over uneven surfaces. Extra heavy-duty 5-Inch swivel casters give the truck increased strength and maneuverability in the horizontal position. The truck has an 18-Inch wide toe plate to accommodate larger bulky loads. 51.75-Inch height is great for high-stacking applications. It is rust and corrosion resistant. This truck ships fully assembled. Milwaukee-The Name the Pros Trust.
