Abstract

A truck in accordance with the present invention includes a dump body, a truck frame with a rear axle, a lift system, and a conveying system. The dump body is defined by a unitary floor, a pair of sidewalls which extend tip from opposite sides of the floor, and a front wall and a back wall located on opposite sides of the floor and extending between the sidewalls. The dump body is pivotally connected to the truck frame adjacent to the back wall. The lift system is mounted to the truck frame and the dump body for lifting an end of the dump body proximate the front wall between a lowered resting position on the truck frame and an upper raised position. The conveying system is positioned on the floor behind the rear axle and extends between the pair of sidewalls. The dump body has at least one opening in alignment with the conveying system.

Claims

1. A truck for hauling and dispensing material, the truck comprising:

a truck frame with a rear axle mounted on the truck frame;

a dump body comprising

a receptacle including a bottom and a front wall and

a tailgate which with the receptacle define a single interior space, the dump body pivotally connected to the truck frame adjacent to the tailgate;

a lift system mounted to the truck frame and the dump body for lifting an end of the dump body proximate the front wall between a lowered resting position on the truck frame and an upper raised position; and

a conveying system positioned at least partly below the bottom of the receptacle and located behind the rear axle and substantially parallel with the tailgate;

the dump body having at least one opening in alignment with the conveying system, and completely penetrating said receptacle for gravity dispensing of the material from the receptacle.

2. The truck as set forth in claim 1 wherein the dump body has at least one sidewall and the opening is in the sidewall.

3. The truck as set forth in claim 1 wherein the dump body has a pair of sidewalls and a pair of openings, with one of the openings in each of the sidewalls.

4. The truck as set forth in claim 1 wherein the opening is in the bottom.

5. The truck as set forth in claim 1 wherein the dump body has a pair of openings in the bottom.

6. The truck as set forth in claim 1 further comprising a spreader system mounted on the dump body and extending below the opening to spread material discharged by the conveying system.

7. The truck as set forth in claim 1 further comprising at least one door adjustably connected to the dump body, the door moveable between a first position covering the opening and a second position exposing the opening.

8. The truck as set forth in claim 7 wherein the door can be moved to an intermediate position between the first and second positions.

9. The truck as set forth in claim 1 wherein the conveying system comprises an endless conveyor.

10. The truck as set forth in claim 1 wherein the conveying system comprises an auger system.

11. A dump body for hauling, dumping, and dispensing aggregate material when pivotally mounted on a truck frame having front and rear ends, a longitudinal centerline, and front and rear axles supported from the frame, wherein the dump body comprises:

a receptacle having a floor which includes a back edge locatable rearward of the rear axle, a pair of sidewalls extending from and on opposite sides of the floor, and a front wall extending from the floor and between the sidewalls;

a back wall spanning said sidewalls at said back edge and thereby defining with the receptacle a single interior space extending from the front wall to the back wall, for holding said material;

a conveying system mounted in the floor rearward of the rear axle and extending at least partly below the floor between said opposing sides of the floor along a conveying axis oriented transversely to the frame longitudinal centerline;

at least one dispensing passage substantially intersecting the conveying axis and completely penetrating said receptacle, for gravity dispensing of the conveyed material from the receptacle; and

wherein the passage Penetrates the floor.

12. A dump body for hauling, dumping, and dispensing aggregate material when pivotally mounted on a truck frame having front and rear ends, a longitudinal centerline, and front and rear axles supported from the frame, wherein the dump body comprises:

a receptacle having a floor which includes a back edge locatable rearward of the rear axle, a pair of sidewalls extending from and on opposite sides of the floor, and a front wall extending from the floor and between the sidewalls;

a back wall spanning said sidewalls at said back edge and thereby defining with the receptacle a single interior space extending from the front wall to the back wall, for holding said material;

a conveying system mounted in the floor rearward of the rear axle and extending at least partly below the floor between said opposing sides of the floor along a conveying axis oriented transversely to the frame longitudinal centerline;

at least one dispensing passage substantially intersecting the conveying axis and completely penetrating said receptacle, for gravity dispensing of the conveyed material from the receptacle; and

wherein the receptacle has a pair of passages penetrating the floor.

13. A dump body for hauling, dumping, and dispensing aggregate material when pivotally mounted on a truck frame having front and rear ends, a longitudinal centerline, and front and rear axles supported from the frame, wherein the dump body comprises:

a receptacle having a floor which includes a back edge locatable rearward of the rear axle, a pair of sidewalls extending from and on opposite sides of the floor, and a front wall extending from the floor and between the sidewalls;

a back wall spanning said sidewalls at said back edge and thereby defining with the receptacle a single interior space extending from the front wall to the back wall, for holding said material;

a conveying system mounted in the floor rearward of the rear axle and extending at least partly below the floor between said opposing sides of the floor along a conveying axis oriented transversely to the frame longitudinal centerline;

at least one dispensing passage substantially intersecting the conveying axis and completely penetrating said receptacle, for gravity dispensing of the conveyed material from the receptacle; and

at least one door adjustably connected to the receptacle, the door movable between a first position covering the passage and a second position exposing the passage and including an intermediate position between the first and second positions.
