The bucket pin (or bucket hinge pin) on an excavator serves as a pivotal connection point between the digging bucket and the stick (dipper arm). It allows the bucket to rotate smoothly during digging, scooping, and dumping operations, enabling precise control over material handling. The pin's robust design withstands heavy loads and shear forces while maintaining flexibility for articulation. Proper lubrication ensures durability, reducing wear from friction during repetitive movements. Essentially, the bucket pin is critical for transmitting hydraulic force from the arm cylinders to the bucket, facilitating efficient earth-moving, grading, and loading tasks with stability and maneuverability.
