SPEED CONTROL FOR HYDRAULIC SYSTEM OF A REFUSE VEHICLE
A refuse vehicle including 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 comprising one or more memory devices coupled to one or more processors, the one or more memory devices configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to: determine a load of the hydraulic actuator, and control a speed of the electric motor driving the hydraulic pump to achieve the load.
HYDRAULIC SYSTEM FOR A REFUSE VEHICLE
A refuse vehicle including a first electric motor powered by a battery, a first hydraulic pump driven by the first electric motor, a packer actuator powered by the first hydraulic pump, a second electric motor powered by the battery, a second hydraulic pump driven by the second electric motor, a door actuator powered by the second hydraulic pump, and a lift actuator driven by the second hydraulic pump.
REFUSE VEHICLE WITH ELECTRIC REACH APPARATUS
A refuse vehicle includes a chassis, tractive elements, a lift apparatus, and a reach assembly. The tractive elements couple with the chassis and support the refuse vehicle. The lift apparatus includes a track and a grabber assembly. The track includes a straight portion and a curved portion. The grabber assembly releasably grasps a refuse container and ascends or descends the track to lift and empty refuse into a body of the refuse vehicle. The reach assembly includes an outer member, a first extendable member, and a second extendable member. The first extendable member is received within an inner volume of the outer member and translates relative to the outer member. The second extendable member is received within an inner volume of the first extendable member and translates relative to the first extendable member. The lift apparatus is fixedly coupled at an outer end of the second extendable member.
ELECTRIC TAILGATE FOR ELECTRIC REFUSE VEHICLE
Another implementation of the present disclosure is a refuse vehicle. The refuse vehicle includes a chassis, a body coupled with the chassis, a tailgate, an electric lock, and a fully electric tailgate actuator assembly. The body assembly defines a refuse compartment. The tailgate is coupled with a rear of the body and is transitionable between a first position to limit access to the refuse compartment and a second position to allow access to the refuse compartment. The electric lock is operable between an engaged state and a disengaged state to limit movement of the tailgate out of the first position when the electric lock is in the engaged state. The fully electric tailgate actuator assembly is configured to transition the tailgate between the first position and the second position.
Electric tailgate for electric refuse vehicle

The tailgate is coupled with a rear of the body and is transitionable between a first position to limit access to the refuse compartment and a second position to allow access to the refuse compartment. The electric lock is operable between an engaged state and a disengaged state to limit movement of the tailgate out of the first position when the electric lock is in the engaged state. The fully electric tailgate actuator assembly is configured to transition the tailgate between the first position and the second position.
Automatic control of a refuse front end loader
An automatic control system for a refuse vehicle includes a mode select switch disposed within the vehicle that generates a mode select signal based on input from an operator of the vehicle, a control mechanism disposed within the vehicle that operates in response to the mode select signal, and a plurality of sensors adapted to sense a plurality of characteristics of the vehicle and adapted to communicate the plurality of sensed characteristics. The system further includes a control module that receives control instructions from the control mechanism and selectively controls at least one component of a plurality of components of the vehicle based on the mode select signal, at least one of the plurality of sensed characteristics, and the control instructions.
HYDRAULIC CYLINDER MONITORING
A refuse collection vehicle has various hydraulic actuators including at least one cylinder with an internal seal. A sensor is responsive to movement of the piston and sends a signal to a controller to indicate piston movement information during an associated vehicle body component movement. The controller is configured to determine a motion characteristic of the piston during a predetermined body component movement, compare the determined motion characteristic to a stored reference motion characteristic, and in response to determining that a difference between the determined motion characteristic and the reference motion characteristic is greater than a predetermined value, trigger an indication that the refuse collection vehicle is in need of service.
REFUSE COLLECTION VEHICLE HAVING CUSTOMIZED LOAD EDGE
A refuse collection vehicle includes a collection mechanism having a collection hopper which accommodates the collection of refuse by dumping into the collection hopper. A bolt-on load edge bracket is configured to be attached to a portion of the collection mechanism adjacent the collection hopper, is capable of defining an adjustable rear load edge based upon where the attachment is made. By using a separate bolt-on load edge bracket, the rear of the collection vehicle can be tailored to accommodate various load edge heights, and to allow several alternative tipper mechanisms to be the easily attached thereto.
LARGE CAB INNOVATIONS
A refuse truck includes a chassis, a body, a lift assembly coupled to the chassis and/or the body, a cab coupled to the chassis and positioned in front of the body, and a control system. The cab includes an armrest comprising controls pivotable between an active position and an inactive position and an armrest position sensor configured to determine a position of the armrest between the active position and the inactive position. The control system configured to control a user interface to provide an indication of a current position of the lift assembly. The control system further configured to determine a position of the armrest, and selectively activate a pendent control on an exterior of the body.
Electric grasping apparatus for refuse vehicle
A refuse vehicle includes a chassis, multiple tractive elements, a reach assembly, and a lift assembly. The multiple tractive elements are coupled with the chassis and configured to support the refuse vehicle. The reach assembly is coupled with the refuse vehicle. The lift assembly is coupled with the reach assembly. The lift assembly includes a track and a fully-electric grabber assembly. The track includes a straight portion and a curved portion. The fully-electric grabber assembly can ascend or descend the track and includes a carriage, a first grabber arm, a second grabber arm, and an electric motor. The carriage is configured to movably couple with the track. The first grabber arm and the second grabber arm are pivotally coupled with the carriage at opposite ends of the carriage. The electric motor is configured to drive the first grabber arm and the second grabber arm to rotate relative to the carriage.
