System and method for electronic power take-off controls
A refuse vehicle includes a battery and electric power take-off system that includes a second motor configured to convert electrical power into hydraulic power, an inverter configured to provide electrical power to the second motor from the battery, a heat dissipation device in thermal communication with the inverter, wherein the heat dissipation device includes a plurality of conduits and a thermal fluid pump configured to pump cooling fluid through the plurality of conduits, a thermal sensor configured to detect thermal energy within the inverter, a flow meter configured determine a flow rate of cooling fluid through the plurality of conduits, and a controller configured to receive data from the thermal sensor and the flow meter and provide operating parameters to the heat dissipation device.
EXTENDABLE LIFT ARM ASSEMBLY FOR A FRONT END LOADING REFUSE VEHICLE
A lift assembly includes a lift arm having a first arm portion, a second arm portion, a first actuator, and a second actuator. The first arm portion has a first end coupled to a chassis and/or a body of a vehicle. The second arm portion interfaces with the first arm portion and terminates with a second end. The first actuator facilitates repositioning the second arm portion relative to the first arm portion. The second actuator facilitate pivoting the first arm portion about the first end. The first actuator is configured to reposition the second arm portion relative to the first arm portion when the second actuator pivots the lift arm between a stowed position and a working position such that a relative distance between the first end and the second end changes as the second actuator pivots the lift arm between the stowed position and the working position.
REFUSE VEHICLE WITH ELECTRIC LIFT
A fully-electric lift assembly for a refuse vehicle includes a track, a carrier, and a push chain. The track includes multiple channels that extend along an entire length of a path of the track. The carrier is configured to translate along the path of the track. The carrier includes multiple slidable members, each slidable member configured to engage the track at a corresponding one of the channels. The push chain is configured to couple with the carrier at a first end and be driven by an electric motor. The push chain is configured to exert a pushing force on the carrier to drive the carrier to ascend along the track.
Extendable lift arm assembly for a front end loading refuse vehicle
A lift assembly includes a lift arm having a first arm portion, a second arm portion, a first actuator, and a second actuator. The first arm portion has a first end coupled to a chassis and/or a body of a vehicle. The second arm portion interfaces with the first arm portion and terminates with a second end. The first actuator facilitates repositioning the second arm portion relative to the first arm portion. The second actuator facilitate pivoting the first arm portion about the first end. The first actuator is configured to reposition the second arm portion relative to the first arm portion when the second actuator pivots the lift arm between a stowed position and a working position such that a relative distance between the first end and the second end changes as the second actuator pivots the lift arm between the stowed position and the working position.
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.
Refuse Collection Vehicle With Telescoping Arm
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.
Deformable gripper arm
A refuse collection vehicle includes a refuse grabber assembly, a lift arm coupled to the refuse grabber assembly, and a hopper configured to receive refuse from the refuse container. The lift arm is operable to position the refuse grabber assembly. The refuse grabber assembly includes a first grabber arm and a second grabber arm that are configured to cooperate to engage the refuse container. The first grabber arm includes a first gripper and a first support arm coupled to the first gripper. The first gripper includes a first deformable structure configured to contact a first surface of a refuse container. The second grabber arm includes a second gripper and a second support arm coupled to the second gripper. The second gripper includes a second deformable structure configured to contact a second surface of the refuse container.
Scissors-type lifter for intermediate refuse collection container
A cart lifter assembly is provided that is adapted to be mounted to an intermediate refuse collection container that includes a scissors-type extension assembly for moving the lifter between a first/retracted and a second/extended position. The scissors extension assembly further comprises an elongated channel member configured to be secured to the wall of the intermediate container; a mounting block slidably received in the elongated channel member; first second, third and fourth scissor arms; and a bracket configured to be fixedly mounted to the wall of the intermediate container in spaced relationship to the elongated channel member. A rotary actuator is secured to the bracket and has a rotatable shaft extending from opposite ends thereof, for moving the lifter relative to the intermediate container between the first/retracted position and the second/extended position, with one end of the second scissor arm being removably secured to the rotatable shaft.
MECHANICAL ARM SYSTEM FOR COLLECTING GARBAGE FROM A GARBAGE CONTAINER
The mechanical arm system can include a garbage container holder and at least one mast. The holder can have guiding wheels engaged with adjacent tracks of the mast, the two adjacent tracks both having a lower portion extending upwardly along the mast, the lower portion of the first track being located forwardly of the lower portion of the second track, the lower portion of both tracks leading into corresponding upper portions which are curved rearwardly. The system can have a primary mast and a secondary mast slidably mounted to the primary mast, with the garbage container slidable mounted to the secondary mast. A driving link can simultaneously connect the primary mast to the secondary mast, and the secondary mast to the holder in a manner that when the driving link is moved, both sliding movements are performed in the same direction.
SEMI-AUTONOMOUS REFUSE COLLECTION
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.
