REFUSE TRUCK WITH HELICAL PUMP
A refuse vehicle includes a chassis, an energy storage device, a body, a first electric power take-off system, and a second electric power take-off system. The energy storage device is supported by the chassis and is configured to provide electrical power to a prime mover. Activation of the prime mover selectively drives the refuse vehicle. The body is supported by the chassis. The first electric power take-off system is coupled to at least one of the body and the chassis, and includes a first motor that is configured to drive a helical gear pump to convert electrical power received from the energy storage device into hydraulic power. The second electric power take-off system is coupled to at least one of the body and the chassis, and includes a second motor that is configured to drive the helical gear pump to convert electrical power received from the energy storage device into hydraulic power.

Refuse collection vehicle having bolt-on fenders
To provide additional flexibility for a refuse collection vehicle, a removable fender panels are used on an outside portion of the main collection body. The removable fender panels are formed to have a sloped section that will cause rain, snow and other materials to naturally drain from the panel, thus helping to maintain the appearance of the vehicle. Since the fender panels are removable, they can be easily replaced when excessive signs of wear begin to appear. Further, this provides further flexibility during the manufacturing process since the panels can be manufactured from a wide variety of materials including steel, stainless steel, aluminum and many non-metallic materials.

TRANSITION DOOR FOR REFUSE VEHICLE
A refuse vehicle includes a chassis, a cab coupled to the chassis, a body coupled to the chassis and spaced from the cab such that a gap is positioned therebetween, and a transition door assembly positioned across the gap. The transition door assembly includes a support structure, a door panel, a hinge, a latch, and a latch actuator. The support structure is coupled to the body. The support structure includes a cantilevered arm having a latch retainer positioned or defined therealong. The door panel has a rear edge and a front edge. The hinge pivotably couples the rear edge of the door panel to the body. The latch is disposed along the door panel and positioned to engage with the latch retainer to selectively secure the door panel in a closed orientation. The latch actuator is configured to facilitate disengaging the latch from the latch retainer.

ROUTE PLANNING BASED CONTROL OF A REFUSE VEHICLE HYDRAULIC SYSTEM
A refuse vehicle includes an electric motor powered by a battery, a hydraulic pump driven by the electric motor, a hydraulic actuator powered by the hydraulic pump, and one or more processing circuits being configured to: determine a location of the refuse vehicle including a global position system coordinate, determine a position on a route map using the location, control the hydraulic actuator based on the position on the route map, determine a state of charge of the battery and a threshold for the state of charge below which operation of the electric motor, the hydraulic pump, or the hydraulic actuator is adjusted, and dynamically update the threshold based on the position on the route map or a weight of refuse in a refuse compartment.
