Abstract
A hand truck includes a frame body and a wheel assembly including two wheel units spacedly supported at the frame body to switch between a first operation position and a second operation position for enabling the frame body to be tilted backward to transport a load. In the first operation position, the wheel units are oriented in parallel planes for enabling the frame body to move in a back-and-forth direction, and in the second operation position, the wheel units are oriented to align with each other in a common plane for enabling the frame body to move in a left-and-right direction. Therefore, the hand truck provides two modes of movement for two-dimensional movement.
