## Abstract

An apparatus generally includes a dump frame pivotably coupled to a vehicle's chassis, and a slide frame slidably coupled to the dump frame. The apparatus further includes at least one slide frame actuator for causing sliding movement of the slide frame, and at least one dump frame actuator for causing pivotal movement of the dump frame.

## Claims

### Claim 1

An apparatus for a vehicle having a chassis, the apparatus comprising a dump frame pivotably coupled to the chassis for pivotal movement relative to the chassis, a slide frame for supporting a load, the slide frame slidably coupled to the dump frame such that the slide frame is longitudinally slidable relative to the dump frame, and such that the slide frame pivots along with the dump frame relative to the chassis, the dump frame including a longitudinal engagement portion having a length, the slide frame including a longitudinal channel for receiving the engagement portion of the dump frame, and a bearing material disposed along substantially the entire length of the engagement portion, the bearing material reducing friction associated with the engagement portion relatively sliding within the channel.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein the bearing material is disposed along substantially the entire length of at least the lower surface of the engagement portion.

### Claim 3 (depends on 1)

The apparatus of claim 1, further comprising a lubricant at least partially disposed along at least one sliding surface of the apparatus.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein the bearing material is removably attached to the dump frame.

### Claim 5 (depends on 1)

The apparatus of claim 1, wherein the engagement portion includes a generally rectangular beam having three sides within the longitudinal channel, and wherein the bearing material is disposed along substantially the entire length of each of said three sides of the engagement portion.

### Claim 6 (depends on 1)

The apparatus of claim 1, further comprising at least one seal external to the longitudinal channel for substantially sealing at least one interface between the slide frame and the dump frame to thereby inhibit the ingress of foreign objects and debris into the longitudinal channel along the at least one interface.

### Claim 7 (depends on 1)

A vehicle comprising the apparatus of claim 1.

### Claim 8

An apparatus for a vehicle having a chassis, the apparatus comprising a dump frame pivotably coupled to the chassis for pivotal movement relative to the chassis, a slide frame for supporting a load, the slide frame slidably coupled to the dump frame such that the slide frame is longitudinally slidable relative to the dump frame, and such that the slide frame pivots along with the dump frame relative to the chassis, the dump frame including a longitudinal engagement portion having a length, the slide frame including a longitudinal channel for receiving the engagement portion of the dump frame, and a bearing material disposed along substantially the entire length of the engagement portion, the bearing material reducing friction associated with the engagement portion relatively sliding within the channel, the bearing material configured to make contact with and substantially seal at least one sliding surface along substantially the entire length of the at least one sliding surface to thereby inhibit foreign objects and debris from contacting the at least one sliding surface.

### Claim 9 (depends on 8)

The apparatus of claim 8, wherein the bearing material is disposed along substantially the entire length of at least one of the upper surface or the lower surface of the engagement portion.

### Claim 10 (depends on 8)

The apparatus of claim 8, further comprising a lubricant at least partially disposed along at least one sliding surface of the apparatus.

### Claim 11 (depends on 8)

The apparatus of claim 8, wherein the bearing material is removably attached to the dump frame.

### Claim 12 (depends on 8)

The apparatus of claim 8, wherein the engagement portion includes a generally rectangular beam having three sides within the longitudinal channel, and wherein the bearing material is disposed along substantially the entire length of each of said three sides of the engagement portion.

### Claim 13 (depends on 8)

The apparatus of claim 8, further comprising at least one seal external to the longitudinal channel for substantially sealing at least one interface between the slide frame and the dump frame to thereby inhibit the ingress of foreign objects and debris into the longitudinal channel along the at least one interface.

### Claim 14 (depends on 8)

A vehicle comprising the apparatus of claim 8.
