The arm is the primary structural component of a wheeled excavator that connects the boom to the bucket, enabling digging, lifting, and material handling operations.
The arm, also known as the dipper or stick, is a critical articulated component in wheeled excavators that transmits hydraulic force from the boom to the bucket. It functions as a lever system that determines the machine's digging depth, reach, and lifting capacity through precise angular movements controlled by hydraulic cylinders. This component must withstand significant bending moments, torsional stresses, and cyclic loading during excavation operations while maintaining structural integrity and dimensional stability.

Wheeled excavator arms are typically lighter and designed for faster cycle times with slightly reduced digging forces compared to tracked versions, optimized for mobility and versatility on hard surfaces.
Arm connection points should be inspected every 250 operating hours for wear, with lubrication applied daily. Complete pin and bushing replacement is typically required every 2,000-3,000 hours depending on operating conditions.
