A method and apparatus is provided for improved hand trucks. In some embodiments, a hand truck has side members extending from the frame to help retain objects being moved with the hand truck. The side members extend outward from the frame of the hand truck to prevent round objects from rolling sideways off the hand truck while in transit.

1. A hand truck comprising: a frame having a bottom portion and a top portion;two or more wheels coupled to the frame;a horizontal base plate coupled to the frame proximate the bottom portion of the frame;a rigid curved wall coupled to the frame and extending outward and forward from the frame, the rigid curved wall being comprised of a semi-circular panel extending upward from the bottom portion of the frame to the top portion of the frame, wherein the rigid curved wall forms a pocket for retaining objects being moved with the hand truck wherein the rigid curved wall has a radius of curvature large enough that the rigid curved wall extends outward substantially beyond the two or more wheels; anda plurality of pairs of apertures formed in the rigid curved wall, each of the pairs of apertures formed at a tangent of the rigid curved wall at locations enabling one or more fasteners to pass through the apertures and around the frame to secure the rigid curved wall to the frame. 2. The hand truck of claim 1, wherein the rigid curved wall is formed by first and second semi-circular panels coupled to the frame. 3. The hand truck of claim 1, wherein the rigid curved wall is vertically expandable. 4. The hand truck of claim 1, wherein the rigid curved wall is horizontally expandable. 5. The hand truck of claim 1, further comprising first and second handles coupled to the frame and extending from the back of the hand truck. 6. The hand truck of claim 1, further comprising a movable bottom plate movably coupled to the rigid curved wall. 7. The hand truck of claim 6, wherein the movable bottom plate is coupled to the rigid curved wall by dovetail joints. 8. The hand truck of claim 6, wherein the movable bottom plate is coupled to the rigid curved wall by a hinge. 9. A method of retaining objects in a hand truck, the hand truck having a frame with a bottom portion and a top portion, two or more wheels coupled to the frame, and a horizontal base plate coupled to the frame proximate the bottom portion of the frame, the method comprising: coupling a rigid curved wall to the frame, the rigid curved wall extending outward and forward from the frame, wherein the rigid curved wall extends outward substantially past the two or more wheels, and wherein the rigid curved wall extends upward from the bottom portion of the frame to the top portion of the frame; andforming a plurality of pairs of apertures in the rigid curved wall, each of the pairs of apertures formed at a tangent of the rigid curved wall at locations enabling one or more fasteners to pass through the apertures and around the frame to secure the rigid curved wall to the frame. 10. The method of claim 9, further comprising movably coupling a bottom plate to the hand truck to increase the surface area upon which the objects can be supported. 11. The method of claim 10, wherein the bottom plate is coupled to the hand truck by a hinge. 12. The method of claim 10, wherein the bottom plate is slidably received by the hand truck. 13. The method of claim 12, further comprising forming dovetail joints to secure the bottom plate to the hand truck. 14. The method of claim 10, wherein the rigid curved wall is vertically expandable. 15. The method of claim 10, wherein the rigid curved wall is horizontally expandable. 16. A hand truck comprising: a frame having a bottom portion and a top portion;two or more wheels coupled to the frame;a horizontal base plate coupled to the frame proximate the bottom portion of the frame;a curved panel coupled to the frame of the hand truck, the curved panel forming a concave pocket above the horizontal base plate for retaining objects moved with the hand truck, the curved panel extending from the bottom portion of the frame to the top portion of the frame, the curved panel having a radius of curvature and outside edges, wherein the radius of curvature large enough that the outside edges of the curved panel extend outward substantially beyond the two or more wheels when coupled to the frame; anda plurality of pairs of apertures formed in the curved panel, each of the pairs of apertures formed at a tangent of the curved panel at locations enabling one or more fasteners to pass through the apertures and around the frame to secure the curved panel to the frame. 17. The hand truck of claim 16, wherein the curved panel is formed by first and second sub-panels. 18. The hand truck of claim 16, further comprising a movable bottom plate coupled to the curved panel. 19. The hand truck of claim 1, further comprising a plurality of zip ties, each zip tie passing through one of the pairs of apertures and around the frame to secure the rigid curved wall to the frame. 20. The method of claim 9, further comprising inserting a plurality of zip ties through adjacent apertures and around the frame to secure the rigid curved wall to the frame.
