• Specifiion

• Design & function

1.Structural Role
It acts as a rigid pivot axle, connecting moving components (e.g., the boom to the arm) while allowing controlled rotation. The pin’s cylindrical shape ensures smooth, low-friction movement of the joint, which is essential for precise operator control during tasks like bucket positioning.

2.Load-Bearing Role
Constructed from high-tensile steel, it absorbs and distributes extreme forces generated during digging or lifting—including vertical loads (from heavy materials) and lateral forces (from twisting motions). Its heat-treated surface resists wear, even when in constant contact with bushings (the cylindrical sleeves that line the joint holes).
