Abstract

A refuse vehicle includes a chassis, a body, a primary ejector, and an auxiliary ejector. The chassis includes a frame and a cab disposed at one end of the frame. The body includes a hopper portion and a storage portion. The width of the storage portion is greater than the width of the hopper portion. The auxiliary ejector has a width equal to the difference between the width of the storage portion and the width of the hopper portion. The primary ejector is selectively repositionable within the hopper portion and the storage portion of the body to at least one of compact refuse therein or eject refuse therefrom. The auxiliary ejector is selectively repositionable within the storage portion of the body to at least one of compact refuse therein and eject refuse therefrom in tandem with the primary ejector.

Claims

1. A refuse vehicle, comprising:

a chassis including a frame and a cab disposed at one end of the frame;

a body including a hopper portion having a first width and a storage portion having a second width greater than the first width, wherein the hopper portion is positioned forward of the storage portion, between the storage portion and the cab;

a primary ejector having a width equal to the first width; and

an auxiliary ejector having a width equal to the difference between the first width and the second width,

wherein the primary ejector is selectively repositionable within the hopper portion and the storage portion of the body to at least one of compact refuse therein and eject refuse therefrom, and wherein the auxiliary ejector is selectively repositionable within the storage portion of the body to at least one of compact refuse therein and eject refuse therefrom in tandem with the primary ejector.

2. The refuse vehicle of claim 1, further comprising a container handling system configured to lift and dump refuse from a refuse container into the hopper portion.

3. The refuse vehicle of claim 2, wherein the container handling system is positioned alongside the hopper portion and forward of the storage portion of the body, wherein the container handling system is configured to interface with refuse containers disposed to a side of the body such that the refuse vehicle is a side-loading refuse vehicle.

4. The refuse vehicle of claim 1, wherein the body includes a front post positioned at a front end of the hopper portion, a rear post positioned at a rear end of the storage portion, and a mid post positioned at the interface between the storage portion and the hopper portion.

5. The refuse vehicle of claim 4, further comprising an actuator positioned to selectively reposition the primary ejector between a first position at the front post, a second position at the mid post, and a third position at the rear post.

6. The refuse vehicle of claim 5, wherein at least one of the primary ejector and the auxiliary ejector include a pickup configured to selectively couple the primary ejector and the auxiliary ejector such that movement of the primary ejector due to engagement of the actuator also repositions the auxiliary ejector.

7. The refuse vehicle of claim 6, wherein the pickup comprises a locking plate, a catch, and a second actuator configured to selectively engage the catch with the locking plate.

8. The refuse vehicle of claim 5, further comprising a second actuator positioned to selectively reposition the auxiliary ejector between the mid post and the rear post.

9. The refuse vehicle of claim 1, wherein the storage portion of the body has a width equal to 102 inches.

10. A refuse vehicle, comprising:

a chassis including a frame and a cab disposed at one end of the frame;

a body including a hopper portion having a first width and a storage portion having a second width greater than the first width, wherein the hopper portion is positioned forward of the storage portion, between the storage portion and the cab;

a primary ejector having a width that corresponds with the first width; and

an auxiliary ejector, wherein the combined widths of the primary ejector and the auxiliary ejector correspond with the second width,

wherein the primary ejector is selectively repositionable along a primary ejector track extending through the hopper portion and the storage portion and wherein the auxiliary ejector is selectively repositionable along an auxiliary ejector track extending through the storage portion.

11. The refuse vehicle of claim 10, further comprising a container handling system configured to lift and dump refuse from a refuse container into the hopper portion.

12. The refuse vehicle of claim 11, wherein the container handling system is positioned alongside the hopper portion and forward of the storage portion of the body, wherein the container handling system is configured to interface with refuse containers disposed to a side of the body such that the refuse vehicle is a side-loading refuse vehicle.

13. The refuse vehicle of claim 12, wherein at least one of the primary ejector and the auxiliary ejector include a pickup configured to selectively couple the primary ejector and the auxiliary ejector such that movement of the primary ejector due to engagement of the actuator also repositions the auxiliary ejector.

14. The refuse vehicle of claim 13, wherein the pickup comprises a locking plate, a catch, and a second actuator configured to selectively engage the catch with the locking plate.

15. The refuse vehicle of claim 12, further comprising a second actuator positioned to selectively reposition the auxiliary ejector between the mid post and the rear post.

16. A side-loading refuse vehicle, comprising:

a chassis including a frame and a cab disposed at one end of the frame;

a body including a storage portion and a hopper portion positioned between the storage portion and the cab, wherein a wall of the body that defines the hopper portion is inset relative to a wall of the body that defines the storage portion such that the body defines a space between the storage portion and the cab, alongside the hopper portion, that is configured to receive a container handling system;

at least two ejectors, wherein a first of the ejectors has a first sweep area extending through the hopper portion and one lateral side of the storage portion of the body, the first sweep area narrower than the storage portion of the body, wherein a second of the ejectors has a second sweep area extending through a second lateral side of the storage body, and wherein the second sweep area is disposed rearward of the space defined by the body that is configured to receive the container handling system such that the second ejector sweeps a dead zone not accessible to the first ejector.

17. The side-loading refuse vehicle of claim 16, further comprising a container handling system configured to lift and dump refuse from a refuse container into the hopper portion, wherein the container handling system is positioned within the space defined by the body.

18. The side-loading refuse vehicle of claim 17, wherein at least one of the at least two ejectors include a pickup configured to selectively couple the at least two ejectors such that movement of one of the ejectors due to engagement of an actuator also repositions the other actuator.

19. The side-loading refuse vehicle of claim 18, wherein the pickup comprises a locking plate, a catch, and a second actuator configured to selectively engage the catch with the locking plate.

20. The side-loading refuse vehicle of claim 17, further comprising at least two actuators positioned to selectively reposition the at least two ejectors.
