the cargo carrying tray is mounted above the handles; and
the connection strut comprises an elongate member configured to be mounted between the pivot bracket and a forward surface of the cargo carrying tray to provide a connection between the pivot bracket and forward surface of said tray.
2. The connection strut of claim 1 , wherein said connection strut is configured and dimensioned to connect the upper forward portion of the cargo carrying tray to the pivot bracket at a point forward of the transition section.
3. The connection strut of claim 2 , wherein the connection struts are configured and dimensioned to transfer load in the cargo carrying tray to the forward end portion of the pivot bracket when wheelbarrow is being tipped or emptied.
4. The connection strut of claim 2 , wherein the elongate members of the connection struts have opposed ends with each end forming an attachment flange.
5. The connection strut of claim 4 , wherein a body portion of the elongate members between the attachment flange has a structural shape configured to resist bending.
6. The connection strut of claim 5 , wherein the connection struts have a cross section configured as a flat, square or round shape.
7. A kit for altering load carrying characteristics of a wheelbarrow having two handles with corresponding forward end sections, at least one wheel rotatable around a rotational axis, a pivot bracket joining the two handle forward end sections in front of the at least one wheel and a cargo carrying tray mounted above the handles, said kit comprising:
a pivot bracket with spaced first and second support legs with a bight joined therewith, each of the first and second support legs having a forward end portion and a back end portion, wherein the back end portions of the first and second support legs are designed and configured to be attached to the forward end sections of the wheelbarrow handles, and wherein:
at least a portion of the bight is located between the forward end portions of the first and second support legs;
the bight is designed and configured to be located forward and above the rotational axis of the wheel when the pivot bracket is installed on the wheelbarrow and the wheelbarrow is resting on a flat level surface without being tilted forward;
said first and second support legs each have a forward section and a rearward section with the rearward section being the section designed and configured to be attached to the forward end section of the handles and the forward section being inclined upward from a transition section joining with the rearward section, and wherein said transition section is positioned to lie inside the radius of the wheelbarrow wheel when mounted to the wheelbarrow; and
connection struts comprising an elongate member configured to be mounted between the pivot bracket and a forward surface of the cargo carrying tray to provide a connection between the pivot bracket and forward surface of said tray.
8. The kit of claim 7 , wherein said connection struts are configured and dimensioned to connect the upper forward portion of the cargo carrying tray to the pivot bracket at a point forward of the transition section.
9. The kit of claim 8 , wherein the connection struts are configured and dimensioned to transfer load in the cargo carrying tray to the forward end portion of the pivot bracket when wheelbarrow is being tipped or emptied.
10. The kit of claim 8 , wherein the elongate members of the connection struts have opposed ends with each end forming an attachment flange.
11. The kit of claim 10 , wherein a body portion of the elongate members between the attachment flange has a structural shape configured to resist bending.
12. The connection struts of claim 11 , wherein the connection struts have a cross section configured as a flat, square or round shape.
13. A method of altering load carrying characteristics of a wheelbarrow having two handles with corresponding forward end sections, at least one wheel rotatable around a rotational axis, a pivot bracket joining the two handle forward end sections in front of the at least one wheel and a cargo carrying tray mounted above the handles, said method comprising:
installing a pivot bracket on the wheelbarrow, the pivot bracket having spaced first and second support legs with a bight joined therewith, each of the first and second support legs having a forward end portion and a back end portion, wherein the back end portions of the first and second support legs are designed and configured to be attached to the forward end sections of the wheelbarrow handles, and wherein:
at least a portion of the bight is located between the forward end portions of the first and second support legs;
the bight is designed and configured to be located forward and above the rotational axis of the wheel when the pivot bracket is installed on the wheelbarrow and the wheelbarrow is resting on a flat level surface without being tilted forward;
said first and second support legs each have a forward section and a rearward section with the rearward section being the section designed and configured to be attached to the forward end section of the handles and the forward section being inclined upward from a transition section joining with the rearward section, and wherein said transition section is positioned to lie inside the radius of the wheelbarrow wheel when mounted to the wheelbarrow; and
installing a connection strut between a forward surface of the cargo carrying tray and the pivot bracket, wherein the connection strut comprises an elongate structural member configured to be mounted to the cargo carrying tray and to the pivot bracket to provide a connection therebetween.
14. The method of claim 13 , wherein said connection strut is configured and dimensioned to connect the upper forward portion of the cargo carrying tray to the pivot bracket at a point forward of the transition section.
15. The method of claim 14 , wherein the connection strut is configured and dimensioned to transfer load in the cargo carrying tray to the forward end portion of the pivot bracket when wheelbarrow is being tipped or emptied.
16. The method of claim 14 , wherein the elongate members of the connection strut has opposed ends with each end forming an attachment flange.
17. The method of claim 16 , further comprising attaching the connection strut by placing a mechanical fastener through corresponding holes in the attachment flanges, cargo carrying tray and pivot bracket.
18. The method of claim 16 , further comprising attaching the connection strut by welding the attachment flanges to the cargo carrying tray and pivot bracket, respectively.
19. The method of claim 16 , wherein a body portion of the elongate members between the attachment flange has a structural shape configured to resist bending.
20. The connection struts of claim 19 , wherein the connection strut has a cross section configured as a flat, square or round shape.
