The powered hand truck with pivoting tracks includes a chassis containing the components for general operation. A common pivot axle extends through the chassis and a pair of tracks is pivotally attached to opposite ends of the common pivot axle. This connection to the pivot axle permits each track to pivot passively with respect to the chassis independently of the other. An extendable control arm has one end attached to each opposing side of the chassis and an opposing end attached to a corresponding track. The control arm controls the extent of pivoted positioning of the connected track to dampen pivoting of the corresponding track within a predetermined range.
