The Magliner HMK15AUAC aluminum hand truck has a straight back frame, vertical loop handle, diecast aluminum nose plate, 10" microcellular foam wheels and a 500 lb. load capacity. The hand truck's frame and nose plate are made of aluminum, which weighs less than steel and is resistant to rust and corrosion. The wheels on the hand truck have semi-precision bearings to help reduce friction and support the load. This hand truck requires assembly; instructions and hardware for assembly are included, tools for assembly are sold separately. Hand trucks, also known as two-wheeled dollies, are used to transport heavy or bulky items, especially in commercial product distribution and delivery. Hand trucks are L-shaped, with handles at the top, two wheels at the bottom and a small platform that touches the ground when the truck is upright. A load is placed on the platform and the truck is tilted back, balancing the weight over the wheels. Powered hand trucks have a platform that lifts the load up, or lowers it down, to reduce human labor. Some hand trucks may be convertible to platform trucks for moving large or cumbersome loads. Others fold flat for storage. Magline manufactures Magliner brand hand trucks, dollies, ramps and other products for material handling applications.
