Abstract

Hungry boards, or spill boards, for mounting about a tip truck load carrying body are formed with a pair of spaced apart vertical bores corresponding to and depending downward from the access cutouts. Vertical bores formed through the hungry board receive the threaded end of an anchor bolt which is welded to lip of the body. The anchor bolt comprises part of a resilient fastening system for attachment of the hungry board the anchor bolt is formed with a flat foot from which a shank extends. The shank terminates upwardly in a threaded upper end. A compression spring is located about the shank and arranged to absorb impact forces directed at the hungry board during use. The hungry boards are made of a light weight resilient material such as a tough synthetic rubber.

Claims

1. A hungry board assembly including:

a hungry board (4;

104, 152, 154) formed of a non-ferrous material;

one or more resilient members (152;

142); and

a fastening system (8, 120) for attaching the hungry board to a body of a transportation vehicle by means of said resilient members, the fastening system including one or more anchor members for fastening to the body of the vehicle, each anchor member including an elongate shaft and the resilient members comprise springs located about corresponding ones of the elongate shafts, the springs acting to absorb and dissipate forces directed to the side of the hungry board, thus reducing the likelihood of damage to the hungry board.

2. An assembly according to claim 1, wherein the fastening system includes one or more anchor brackets (46;

166) formed into an underside of the hungry board for fastening to corresponding ones of the anchor members.

3. An assembly according to claim 2, including rotation plates (48;

144) located beneath the anchor brackets.

4. An assembly according to claim 3, wherein the springs are captured between a feet of the anchor members and the rotation plate (48;

144).

5. An assembly according to claim 4, wherein ends of the anchor members opposite the feet penetrate the rotation plate and the body anchor bracket and are retained thereon by respective fastening members (41;

150).

6. An assembly according to claim 5, wherein the hungry boards are formed with cutaways (40;

168) to allow access for a tool to the fastening members.

7. An assembly according to claim 1, wherein the hungry board (4;

104) is formed of an elastomeric material.

8. An assembly according to claim 1, wherein the resilient members (6) may comprise a piece of elastomeric material and/or composite material such as a synthetic rubber.

9. An assembly according to claim 8, wherein the fastening system includes nuts, bolts and washers for retaining one end of the resilient member to the body and another end to the hungry board.

10. An assembly according to claim 9, wherein the hungry board is formed with a series of receptacles (7;

166) to receive corresponding ones of the one or more resilient members.

11. An ore transportation vehicle having a body (2) fitted with a hungry board assembly according to claim 1.
