• Specifiion

• Design & Function

1.Structural Connection: It inserts through aligned holes in two or more linkage components (e.g., boom and arm lugs), creating a rigid yet movable joint that connects major work equipment parts.

2.Rotational Support: The pin’s smooth, cylindrical surface acts as a bearing interface, allowing the connected components (e.g., arm and bucket) to rotate freely during operations like lifting, digging, or dumping.

3.Load Distribution: Its high-strength steel construction distributes heavy loads (from the bucket or lifted materials) evenly across the linkage, preventing stress concentration that could crack lugs or bend components.
