Patent number: 12570144Abstract: A refuse vehicle includes a vehicle body on a chassis having a frame, an internal combustion engine (ICE), and a transmission coupling the ICE with a plurality of tractive elements. The vehicle body includes an electrically powered body system and a hydraulically powered body system. A first power module is coupled with the ICE and is configured to provide rotary power to a hydraulic pump that is configured to provide hydraulic power to the hydraulically powered body system. A second power module is coupled with the transmission and configured to rotationally couple and decouple an electrical generator with the transmission. The generator is configured to charge at least one battery when rotationally coupled with the transmission. The battery is configured to provide electrical power to the electrically powered body system.Type: GrantFiled: February 16, 2023Date of Patent: March 10, 2026Assignee: The Heil Co.Inventors: Stanley L. Maroney, Robert B. Williams, Douglas Michael Anders

Publication number: 20260062212Abstract: Systems and methods for collecting and loading refuse include a refuse loading system configured to couple to a refuse collection vehicle and to load refuse into the refuse collection vehicle and a control system. The refuse loading system includes a container-holding mechanism operable to hold a refuse container, and a positioning system operable to position the container-holding mechanism relative to the refuse collection vehicle. The control system includes a proportional control device, at least one processor, and memory communicably coupled to the at least one processor. The memory stores instructions which, when executed, cause the at least one processor to perform operations including receiving, from an operator, via the proportional control device, an input to control movement of one or components of the refuse loading system, and, responsive to receiving the input, operating the container-holding mechanism and the positioning system to perform a portion of a refuse loading cycle.Type: ApplicationFiled: August 21, 2025Publication date: March 5, 2026Inventors: Tony Lawayne Coffey, Stanley L. Maroney, Phillip A. Kendrick, Jonathan Paul Shadrick, Robert B. Williams, Macey Parris Sarratt

Publication number: 20260062210Abstract: Operating a refuse collection vehicle to collect refuse from a refuse container includes positioning a refuse collection vehicle with respect to a refuse container to be emptied, and manually engaging a switch to initiate a dump cycle to be performed by the refuse collection vehicle on the refuse container. The dump cycle includes engaging the refuse container with a portion of the vehicle, lifting the engaged refuse container to a dump position, and moving the refuse container to release contents of the refuse container into a hopper of the refuse collection vehicle. The dump cycle continues to completion as long as the switch remains manually engaged.Type: ApplicationFiled: November 7, 2025Publication date: March 5, 2026Inventors: Stanley L. Maroney, David G. Lewis, Robert B. Williams

Publication number: 20250353671Abstract: A refuse collection vehicle includes a grabber that is operable to engage a refuse container, a lift arm that is operable to lift a refuse container, at least one sensor that is arranged to collect data indicating an angular position of the grabber, at least one sensor that is arranged to collect data indicating a relative positioning of the lift arm, a first controller for adjusting the angular position of the grabber, and a second controller adjusting the relative positioning of the lift arm. The adjustment of the angular position of the grabber is coordinated with the adjustment of the relative positioning of the lift arm.Type: ApplicationFiled: July 31, 2025Publication date: November 20, 2025Inventors: Stanley L. Maroney, David G. Lewis, Robert B. Williams
