Abstract
A refuse collection vehicle has a container collection arm with a telescoping boom coupled with a refuse stowage unit of the vehicle. A grasping mechanism is coupled with an end of the boom. A rotary actuator couples the grasping mechanism with the boom to enable a waste container to be moved between a pick up position and a dump position.
Claims22
A refuse collection vehicle comprising:
- a hopper;
- an arm configured to grasp a container from a location on one side of the vehicle, the arm comprising:
- a boom configured to telescopically extend and retract relative to a chassis of the 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
- a controller configured to receive user input and regulate operation of the boom and the pivot cylinder to selectively move the arm in alternative direct-path and low-lift-path dump modes based on the user input, wherein:
- in the direct-path dump mode, the boom telescopically retracts while the pivot cylinder extends to move the free end of the boom vertically upward;
- and
- in the low-lift-path dump mode, the boom telescopically retracts while the pivot cylinder retracts to move the free end of the boom vertically downward.

An arm for a refuse collection vehicle, the arm comprising:
- a boom configured to telescopically extend and retract relative to the refuse collection vehicle;
- and
- 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,
- wherein the pivot cylinder is configured to operate in response to control signals and selectively move the arm in alternative direct-path and low-lift-path dump modes, wherein:
- in the direct-path dump mode, the boom telescopically retracts while the pivot cylinder extends to move the free end of the boom vertically upward;
- and
- in the low-lift-path dump mode, the boom telescopically retracts while the pivot cylinder retracts to move the free end of the boom vertically downward.
