Extendable lift arm assembly for a front end loading refuse vehicle

A lift arm assembly for a vehicle, the lift arm assembly comprising:

• a first lift arm including:
• a first arm portion having (i) a first end configured to pivotally couple to a first side of the vehicle and (ii) an opposing second end;
• and
• a second arm portion having (i) a first end that interfaces with the opposing second end of the first arm portion and (ii) an opposing second end configured to interface with an implement;
• a second lift arm including:
• a third arm portion having (i) a first end configured to pivotally couple to an opposing second side of the vehicle and (ii) an opposing second end;
• and
• a fourth arm portion having (i) a first end that interfaces with the opposing second end of the third arm portion and (ii) an opposing second end configured to interface with the implement;
• a first extension actuator positioned to facilitate extending and retracting the second arm portion of the first lift arm relative to the first arm portion of the first lift arm;
• and
• a second extension actuator positioned to facilitate extending and retracting the fourth arm portion of the second lift arm relative to the third arm portion of the second lift arm.

A vehicle comprising:

• a chassis;
• a body coupled to the chassis;
• a cab coupled to the chassis in front of the body;
• and
• a lift arm assembly including:
• a first lift arm including:
• a first arm portion pivotally coupled to a first side of the body;
• a second arm portion interfacing with the first arm portion;
• a first extension actuator positioned to facilitate extending and retracting the second arm portion relative to the first arm portion;
• and
• a first pivot actuator extending between the first side of the body and the first arm portion;
• and
• a second lift arm including:
• a third arm portion pivotally coupled to an opposing second side of the body;
• a fourth arm portion interfacing with the third arm portion;
• a second extension actuator positioned to facilitate extending and retracting the fourth arm portion relative to the third arm portion;
• and
• a second pivot actuator extending between the opposing second side of the body and the third arm portion;
• wherein the first extension actuator and the second extension actuator are configured to extend in response to the first pivot actuator and the second pivot actuator pivoting the first lift arm and the second lift arm between a stowed position and a working position such that the lift arm assembly clears the cab.
