Externally Controlled Switch Mechanism
A control mechanism for a refuse vehicle includes a first control valve that operates a first hydraulically controlled mechanism and a second control valve that operates a second hydraulically controlled mechanism. The control mechanism also includes a plurality of switches and a pneumatic control mechanism. The plurality of switches generates a valve select signal and a mode signal. The pneumatic control mechanism selectively controls the first control valve and the second control valve based on the valve select signal and the mode signal. An operator of the refuse vehicle actuates the plurality of switches while the operator is operating the pneumatic control mechanism.

Refuse vehicle body assembly
A vehicle includes a chassis, a cab coupled to the chassis, a body coupled to the chassis rearward of the cab, a bracket, and a valve assembly. The body defines a compartment. The body includes a bottom wall defining a horizontal plane and a front wall defining a vertical plane. The bracket has an arm that is coupled to and extends rearward from the front wall into the compartment at an angle such that the arm is neither parallel with the horizontal plane nor parallel with the vertical plane. The valve assembly is coupled to the bracket such that at least a portion of the valve assembly is disposed within the compartment.

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 first hydraulic 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 a second hydraulic pump to convert electrical power received from the energy storage device into hydraulic power.
FRONT LIFT ASSEMBLY FOR ELECTRIC REFUSE VEHICLE
A lift assembly for a refuse vehicle includes a lift arm pivotally coupled to a body of the refuse vehicle and a pair of forks pivotally coupled to the lift arm, the pair of forks is configured to engage with a refuse container. The lift assembly further includes an electric lift arm actuator comprising an output shaft. The electric lift arm actuator may be communicably coupled to an electric energy system. The lift assembly further includes a pin coupled to the lift arm assembly and the electric lift arm actuator. The pin is configured to rotate about a pin axis. Rotation of the output shaft causes the lift arm assembly to rotate relative to the body via the pin.

REFUSE VEHICLE
A refuse vehicle includes a body defining a storage compartment, a packer, a hydraulic system, a pressure sensor, and a controller. The hydraulic system includes a first pump and a second pump are configured to supply fluid power to a packer actuator. The packer actuator is coupled to the packer and the body and is positioned to move the packer to compact refuse within the storage compartment. The pressure sensor indicates a measured pressure a first fluid associated with the first pump or a second fluid associated with the second pump. The controller is configured to control the hydraulic system to supply fluid power to the packer actuator to move the packer. The controller is further configured to determine that (a) one or more other vehicle functions are active or (b) the measured pressure exceeds a threshold pressure. The controller is further configured to reduce the fluid power supplied to the packer actuator in response to the determination.

Loading Apparatuses and Vehicles That Include a Loading Apparatus
Example loading apparatuses and vehicles that include loading apparatus are described. An example loading apparatus includes a frame, a lift arm, and an anchor member. The frame has a first mounting member, a second mounting member, a first guide rail, and a second guide rail. The first and second guide rails cooperatively define a slot. The lift arm has a lift arm first end, a lift arm second end, a lift arm first portion, and a lift arm second portion. The lift arm first portion is partially disposed within the slot. Each of the lift arm first portion and the lift arm second portion is moveable between a loading position and a dumping position. The anchor member is attached to the lift arm such that the lift arm is pivotable relative to the anchor member and moveable within the slot.

A refuse vehicle includes a chassis, an energy storage device, a vehicle body, an electric power take-off system, and a hydraulic component. 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 vehicle body is supported by the chassis, and includes an on-board receptacle for storing refuse therein. The electric power take-off system is positioned on the vehicle body, and includes an electric motor configured to drive a hydraulic pump to convert electrical power received from the energy storage device into hydraulic power. An amount of electrical power at least one of received by and provided to the electric motor is limited by a controller to control an output characteristic of the hydraulic pump. The hydraulic component is in fluid communication with the hydraulic pump and configured to operate using hydraulic power from the electric power take-off system.
