Abstract

The present disclosure provides a body for a machine. The body comprises a front wall at a front end of the body. First and second side walls extend from the front wall to a rear end of the body. The first and second side walls each comprising a top side rail. A base extends from the front wall to the rear end and between the first and second side walls. Thus the front wall, first and second side walls and base at least partially form a body cavity for receiving material. Each top side rail comprises an upper side surface and a flange extending upwardly from the upper side surface adjacent to the body cavity. The upper side surface extends downwardly and outwardly away from the flange for directing material from the top side rail and away from the body cavity.

First claim

1 . A body for a machine, the body comprising:
a front wall at a front end of the body; first and second side walls extending from the front wall to a rear end of the dump body, the first and second side walls each comprising a top side rail; and a base extending from the front wall to the rear end and between the first and second side walls such that the front wall, first and second side walls and base at least partially form a body cavity for receiving material, wherein: each top side rail comprises an upper side surface and a flange extending upwardly from the upper side surface adjacent to the body cavity, the upper side surface extending downwardly and outwardly away from the flange for directing material from the top side rail and away from the body cavity.

2 . The body as claimed in claim 1 wherein the flange comprises hardened steel.

3 . The body as claimed in claim 1 wherein the first and second side walls each comprise an inner side plate bounding the body cavity, the inner side plate extending beyond the upper side surface to form the flange.

4 . The body as claimed in claim 3 wherein each inner side plate comprises hardened steel.

5 . The body as claimed in claim 1 wherein the upper side surface extends downwardly and outwardly away from the flange at an angle greater than 90 degrees to the flange.

6 . The body as claimed in claim 1 wherein the dump body comprises a longitudinal axis extending from the front end to the rear end and a lateral axis perpendicular to the longitudinal axis and along which the first side wall is separated from the second side wall.

7 . The body as claimed in claim 6 wherein the upper side surface extends outwardly away from the flange and downwardly at an acute upper side surface angle to the lateral axis for directing material off the top side rail and away from the body cavity.

8 . The body as claimed in claim 7 wherein the upper side surface angle is in the range from 20 degrees to 40 degrees.

9 . The body as claimed in claim 6 wherein the body comprises a vertical axis perpendicular to the longitudinal and lateral axes and the flange comprises an upper edge, further wherein the upper edge is spaced apart from the upper side surface along the vertical axis.

10 . The body as claimed in claim 1 wherein the flange is harder than the upper side surface.

11 . The body as claimed in claim 1 wherein the first and second side walls each comprise an outer side surface, the upper side surface extending from the flange to the outer side surface.

12 . The body as claimed in claim 11 wherein an outer upper side surface edge between the upper side surface and outer side surface is curved.

13 . The body as claimed in claim 11 wherein the first and second side walls each comprise an outer side plate, the outer side plate comprising the upper side surface and outer side surface.

14 . The body as claimed in claim 1 wherein the body comprises a dump body or an ejector body.

15 . A machine comprising a body mounted to a chassis, the body comprising:
a front wall at a front end of the body; first and second side walls extending from the front wall to a rear end of the dump body, the first and second side walls each comprising a top side rail; and a base extending from the front wall to the rear end and between the first and second side walls such that the front wall, first and second side walls and base at least partially form a body cavity for receiving material, wherein: each top side rail comprises an upper side surface and a flange extending upwardly from the upper side surface adjacent to the body cavity, the upper side surface extending downwardly and outwardly away from the flange for directing material from the top side rail and away from the body cavity.
