A wheelbarrow for transporting materials includes an undercarriage, a wheel rotatably mounted to the undercarriage, a pan mounted to and supported by the undercarriage and a fastening mechanism having a head. The pan includes a base wall and an upright wall extending upwardly from the base wall. The base wall and upright wall define a carrying space and a carrying surface facing the carrying space. A depression is formed in the pan defining a depression plane that is generally continuous with the carrying surface. The fastening mechanism mounts the pan to the undercarriage such that the head is positioned within the depression between the undercarriage and the depression plane.

The wheelbarrow of claim 1 wherein the undercarriage includes first and second longitudinal supports, a first handle formed at a proximal end of the first longitudinal support and a second handle formed at a proximal end of the second longitudinal support, the wheel being mounted proximate a distal end of the first and second longitudinal supports. 3. The wheelbarrow of claim 2 wherein the undercarriage further includes a first front brace, a second front brace, a first leg and a second leg, the first front brace mounted between the first longitudinal support and the upright wall and the second front brace mounted between the second longitudinal support and the upright wall, the first leg mounted to the first longitudinal support and the second leg mounted to the second longitudinal support. 4. The wheelbarrow of claim 3 wherein the upright wall includes a front wall, the depression including a first front depression and a second front depression defining first and second front depression planes, the first and second front depressions having a first bottom wall and a second bottom wall, respectively, the fastening mechanism including first and second front bolts, the first and second front braces mounted to the front wall by the first and second front bolts such that the bolt heads of the first and second front bolts are positioned within the first and second front depressions between the first and second bottom walls and the first and second front depression planes, respectively. 5. The wheelbarrow of claim 1 wherein the depression is comprised of first, second, third and fourth base depressions formed in the base wall and first and second front depressions formed in the upright wall. 6. The wheelbarrow of claim 5 wherein the fastening mechanism is comprised of first, second, third, and fourth base bolts, and first and second front bolts, the pan being mounted to the undercarriage by the first, second, third, and fourth base bolts, and the first and second front bolts. 7. The wheelbarrow of claim 1 wherein the pan further includes a transition portion between the base wall and the upright wall, the carrying surface of the transition portion having a generally arcuate-shape, the depression being formed at least partially in the transition portion. 8. The wheelbarrow of claim 1 wherein the depression includes a pair of side walls, a terminal edge and a spacer wall, the depression plane being bounded by an intersection of the side walls, the spacer wall and the terminal edge with the carrying surface. 9. The wheelbarrow of claim 1 wherein the pan is constructed of a polyethylene material. 10. The wheelbarrow of claim 1 wherein the depression has a generally wedge-shape. 11. The wheelbarrow of claim 1, wherein the depression comprises an elongated shape. 12. The wheelbarrow of claim 1, wherein the depression comprises first and second side walls and a spacer wall, the spacer wall extending from the first side wall to the second side wall. 13. The wheelbarrow of claim 12, wherein a depth of the depression is a distance between the bottom wall and the carrying space and wherein the depth is highest at the spacer wall and decreases in a direction away from the spacer wall. 14. The wheelbarrow of claim 1, wherein a shape of the depression and a portion of the carrying surface adjoining the depression are configured to avoid protruding into the carrying space. 15. The wheelbarrow of claim 1, wherein a shape of a portion of the carrying surface adjoining the depression is planar. 16. The wheelbarrow of claim 1, wherein a portion of the bottom wall of the depression adjacent to and outwardly spaced from the head of the fastening mechanism is planar. 17. A wheelbarrow for transporting materials, the wheelbarrow comprising: an undercarriage having at least one longitudinal support; a wheel rotatably mounted to the undercarriage; a pan mounted to and supported by the undercarriage, the pan including a base wall and an upright wall extending upwardly from the base wall, the base wall and upright wall defining a transition portion at their intersection, a first base depression and a base second depression formed at least partially in the transition portion, a first generally planar engagement surface defined between the first and second base depressions on the pan; a first fastening mechanism having a head; and a second fastening mechanism having a head, the head of the first fastening mechanism positioned within the first base depression and the head of the second fastening mechanism positioned within the second base depression, the first engagement surface being in facing engagement with the at least one longitudinal support in an assembled configuration. 18. The wheelbarrow of claim 17 wherein the at least one longitudinal support is comprised of a first longitudinal support and a second longitudinal support, the first longitudinal support having a first handle and the second longitudinal support having a second handle, the first and second longitudinal supports being mounted to the wheel proximate distal ends of the first and second longitudinal supports. 19. The wheelbarrow of claim 18 further comprising: a third base depression formed in the pan at least partially in the transition portion; and a fourth base depression formed in the pan at least partially in the transition portion, a second generally planar engagement surface defined between the third and fourth base depressions, the first engagement surface being in facing engagement with the first longitudinal support and the second engagement surface being in facing engagement with the second longitudinal support in the assembled configuration. 20. The wheelbarrow of claim 18 further comprising: a first front brace mounted between the first longitudinal support and a front wall of the upright wall of the pan; a first front depression formed in the front wall; a first front fastening mechanism mounting the first front brace to the pan such that a head of the first front fastening mechanism is positioned within the first front depression; a second front brace mounted between the second longitudinal support and the front wall; a second front depression formed in the front wall; and a second front fastening mechanism mounting the second front brace to the pan such that a head of the second front fastening mechanism is positioned within the second front depression. 21.
