The stick is a critical structural component in crawler excavators that connects the boom to the bucket, enabling precise digging and material handling operations.
The stick (also known as the dipper arm or crowd arm) is a primary structural member in crawler excavator kinematics, positioned between the boom and bucket. It functions as a lever arm that transmits hydraulic force from the stick cylinder to control bucket penetration depth, digging trajectory, and material handling precision. This component experiences complex dynamic loading including bending moments, torsion, and cyclic fatigue during excavation cycles.
