The hand truck or dolly of the present invention is capable of multi-directional movement and provides an operator with complete control of movement and directional choice for the hand truck without having to remove his hands from a handgrip location to achieve mechanical adjustments of the wheels. Rather, an operator may adjust a wheel index position on-the-fly by means of a trigger assembly to rotate a wheel assembly about a vertical axis of rotation within a range of motion of approximately 100 degrees. The two, independent wheel assemblies of the hand truck of the present invention achieve multi-directional movement through positioning of the wheels in a standard index position allowing for forward and backward movement, a lateral index position allowing for lateral, or side to side, movement, or a rotational index position allowing for rotational movement, such as for cornering and circular movement.
