A patent granted for a lift assembly for refuse vehicles
A recently granted patent (Publication Number: US11772889B2) describes a refuse vehicle with an innovative lift assembly. The vehicle includes a chassis, a body, and a cab, with the lift assembly being coupled to the chassis. The lift assembly consists of two lift arms, each comprising multiple arm portions and interface ends. The arms are connected through actuators that allow for repositioning and pivoting of the lift assembly.
The first lift arm includes a first arm portion with a pivot end and an interface end, while the second lift arm includes a third arm portion with a pivot end and an interface end. The lift assembly can be moved between a stowed position and a working position using actuators coupled to the arms. These actuators facilitate the repositioning of the second arm portion relative to the first arm portion and the fourth arm portion relative to the third arm portion.
One notable feature of the lift assembly is that the relative distance between the pivot ends and the implement ends of the arms changes when the lift assembly is pivoted between the stowed and working positions. This allows for efficient clearance of the cab when the lift assembly is in use.
The patent also describes the positioning of the actuators. The first actuator is positioned internally within the first lift arm, while the second actuator is positioned internally within the second lift arm. Alternatively, the actuators can be positioned externally relative to the lift arms.
Additionally, the patent mentions the inclusion of an implement, such as a fork assembly, quick attach assembly, or plow attachment, which is coupled to the implement ends of the lift arms.
Overall, this patented refuse vehicle design offers improved functionality and efficiency in waste management operations. The unique lift assembly design allows for effective clearance of the cab and flexible repositioning of the arms, enhancing the vehicle's performance in collecting and disposing of refuse.
