  • Patent number: 12679641
    Abstract: A refuse vehicle includes a chassis, a series of tractive elements coupled to the chassis, a refuse compartment coupled to the chassis, a lift arm rotatably coupled to the chassis and configured to engage a refuse container, a lift arm actuator coupled to the chassis and configured to move the lift arm relative to the chassis to raise the refuse container and deposit refuse from the refuse container into the refuse compartment, and a lift assister coupled to the chassis and the lift arm and configured to bias the lift arm to oppose downward movement of the lift arm.

  • Publication number: 20240284645
    Abstract: A cooling system includes a first electrical component, a second electrical component, a first coolant pump fluidly coupled to the first electrical component, and a second coolant pump fluidly coupled to an inlet of the first coolant pump and the second electrical component. The first coolant pump is configured to supply a first portion of coolant to the first electrical component. The second coolant pump is configured to supply the first portion of the coolant to the first coolant pump and a second portion of the coolant to the second electrical component. A radiator is fluidly coupled downstream of the first electrical component and the second electrical component and configured to remove thermal energy from the coolant.

  • Publication number: 20230415982
    Abstract: A refuse vehicle includes a chassis, a body coupled to the chassis and configured to store a volume of refuse, a lift assembly, and a controller. The lift assembly includes a track coupled to the chassis, a track actuator configured to move the track relative to the chassis, a track position sensor configured to provide track position data indicating a position of the track relative to the chassis, a grabber coupled to the track and configured to engage a refuse container, a lift actuator configured to move the grabber relative to the track, and a grabber position sensor configured to provide grabber position data indicating a position of the grabber relative to the track. The controller is configured to control the track actuator and the lift actuator based on the grabber position data and the track position data.

  • Publication number: 20230312236
    Abstract: A refuse vehicle includes a chassis, a body coupled to the chassis, a cab coupled to the chassis, and a lift assembly. The lift assembly includes a positioning member, an interface member coupled to a distal end of the positioning member and configured to engage with a refuse container, an actuator coupled to the positioning member to facilitate repositioning of the interface member and one or more position sensors configured to measure a position of the interface member. The refuse vehicle also includes a return assist system configured to receive a user input to engage the interface member with the refuse container, determine an original position of the refuse container based on the position of the interface member when the user input is received, reposition, using the actuator, the interface member to empty the refuse container into the body, and return the refuse container to the original position.
