ABSTRACT:
A two-wheel hand truck has a frame secured to a bottom plate and forks to support a load in front of the frame. A mount assembly attached to the plate has supports for an oscillating axle. The supports have upright slots accommodating the axle allowing limited relative vertical movement between the axle and the supports. Wheels rotatably mounted on opposite ends of the axle support the truck on a surface. A shaft assembly rotatably mounted on the supports is connected with arms to the axle. A spring unit mounted on the shaft assembly applied torque to the axle to bias the frame to an upright loading position. An angle member secured to the supports covers the axle and spring unit and functions as a foot rest.
