A lift assembly includes a first lift arm including a first arm portion and a second arm portion, a second lift arm including a third arm portion and a fourth arm portion, a first actuator positioned to facilitate repositioning the second arm portion of the first lift arm relative to the first arm portion of the first lift arm, a second actuator positioned to facilitate repositioning the fourth arm portion of the second lift arm relative to the third arm portion of the second lift arm, and one or more pivot actuators positioned to facilitate pivoting the lift assembly between a stowed position and a working position. The first actuator is configured to reposition the second arm portion relative to the first arm portion and the second actuator is configured to reposition the fourth arm portion relative to the third arm portion when the one or more pivot actuators pivot the lift assembly between the stowed position and the working position.

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.

A vehicle includes a chassis, a body coupled to the chassis, and a lift assembly coupled to at least one of the chassis or the body. The lift assembly includes a first lift arm and a second lift arm. The first lift arm includes a first arm portion, a second arm portion interfacing with the first arm portion, a first actuator positioned to facilitate repositioning the second arm portion relative to the first arm portion, and a second actuator positioned to pivot the first arm portion. The second lift arm includes a third arm portion, a fourth arm portion interfacing with the third arm portion, a third actuator positioned to facilitate repositioning the fourth arm portion relative to the third arm portion, and a fourth actuator positioned to pivot the second arm portion.

A front end loading refuse vehicle includes a chassis, a body coupled to the chassis, and a lift arm assembly. The lift arm assembly includes a pair of lift arms and a pair of actuators. Each of the pair of lift arms includes (a) a first arm portion having (i) a first end pivotally coupled to a side of the body and (ii) an opposing second end having a protrusion extending therefrom and (b) a second arm portion having (i) a first end that slidably receives the protrusion of the first arm portion and (ii) an opposing second end configured to interface with an implement. Each of the actuators is positioned externally relative to a respective one of the pair of lift arms and extends between the opposing second end of the first arm portion and the first end of the second arm portion.
