Refuse Collection Vehicle With Telescoping Arm

1 . (canceled)

2 . A refuse collection vehicle comprising:

a hopper;

an arm configured to grasp a container from a location on one side of the refuse collection vehicle, the arm comprising:

a boom configured to telescopically extend and retract relative to a chassis of the refuse collection vehicle;

a pivot cylinder coupled to the boom, the pivot cylinder configured to extend and contract to provide vertical movement of a distal end of the boom; and

at least one rotary actuator coupled to the distal end of the boom, the rotary actuator configured to rotate a grabber; and

a controller configured to receive user input and regulate operation of the arm to selectively move the arm in a direct-path dump mode based on the user input,

wherein, through at least a portion of the direct-path dump mode, the boom telescopically retracts while the pivot cylinder extends to move the distal end of the boom vertically upward and while the rotary actuator rotates the grabber to maintain the container in an upright position.

3 . The refuse collection vehicle of claim 2 , wherein the grabber further comprises a link arm coupled to the rotary actuator.

4 . The refuse collection vehicle of claim 3 , wherein the link arm further comprises a sensor configured to detect whether the link arm is leveled with respect to a ground surface.

5 . The refuse collection vehicle of claim 4 , wherein an output of the sensor enables an auto-leveling feature that is configured to maintain the container parallel to the ground surface.

6 . The refuse collection vehicle of claim 4 , wherein the grabber and the link arm are configured to rotate to a perpendicular position based on an output of the sensor.

7 . The refuse collection vehicle of claim 2 , wherein the grabber comprises a pair of moveable fingers extending parallel to the arm when in a storage position, the pair of moveable fingers configured to converge to grasp the container when in a grasping position.

8 . The refuse collection vehicle of claim 7 , wherein the pair of moveable fingers is operatively connected to a sensor configured to detect a position of the pair of moveable fingers or detect a weight of the container.

9 . The refuse collection vehicle of claim 8 , wherein the sensor comprises at least one of a pressure sensor, a positioning sensor, or a load cell.

10 . The refuse collection vehicle of claim 2 , wherein the grabber is secured to the distal end of the boom via the rotary actuator.

11 . The refuse collection vehicle of claim 2 , wherein the arm further comprises a hose track housing one or more hydraulic hoses, the hydraulic hoses coupled to the grabber, the hose track coupled to the boom and configured to move along the boom during operation of the arm.

12 . The refuse collection vehicle of claim 2 , further comprising a camera mounted onto a top edge of the hopper and facing a refuse stowage unit of the refuse collection vehicle, the camera configured to provide a view of the container when the refuse is dumped from the container into the hopper.

13 . The refuse collection vehicle of claim 12 , further comprising a light source mounted on a top edge of the hopper and adjacent to the camera.

14 . The refuse collection vehicle of claim 2 , wherein the arm further comprises:

a rail system facing a cab of the vehicle;

a mounting assembly comprising a base coupled to the rail system; and

a rail cylinder coupled to the rail system and the base, the rail cylinder configured to extend and retract to provide movement of the base along the rail system.

15 . The refuse collection vehicle of claim 14 , wherein the mounting assembly comprises a journal configured to receive the boom,

wherein the pivot cylinder is rotatably coupled between the boom and the base, and

wherein the journal enables the boom to rotate about a bearing journal axis.

16 . The refuse collection vehicle of claim 2 , wherein the rotary actuator is configured to move in a forward and reverse direction when the arm is in the dump position to shake a container grasped by the arm.

17 . An arm for a refuse collection vehicle, the arm comprising:

a boom configured to telescopically extend and retract relative to the refuse collection vehicle;

a pivot cylinder coupled to the boom, the pivot cylinder configured to extend and contract to provide vertical movement of a free end of the boom; and

at least one rotary actuator coupled to a distal end of the boom, the rotary actuator configured to rotate a grabber,

wherein the pivot cylinder is configured to operate in response to control signals and selectively move the arm in a direct-path dump mode, and

wherein, through at least a portion of the direct-path dump mode, the boom telescopically retracts while the pivot cylinder extends to move the distal end of the boom vertically upward and while the rotary actuator rotates the grabber to maintain a container in an upright position.

18 . The arm of claim 17 , wherein the grabber further comprises a link arm coupled to the rotary actuator.

19 . The refuse collection vehicle of claim 17 , wherein the link arm further comprises a sensor configured to detect whether the link arm is leveled with respect to a ground surface.

20 . The refuse collection vehicle of claim 19 , wherein an output of the sensor enables an auto-leveling feature that is configured to maintain the container parallel to the ground surface.

21 . The refuse collection vehicle of claim 19 , wherein the grabber and the link arm are configured to rotate to a perpendicular position based on an output of the sensor.
