- Key functions & working principle
| Working Principle |
1. Connected to the main boom via a pivot pin at the upper end, and to the bucket via a pivot pin at the lower end |
| 2. The arm hydraulic cylinder (mounted between the boom and arm) extends/retracts to control arm movement (lifting/lowering, digging/pulling) |
| 3. Hydraulic pressure from the excavator’s hydraulic system drives the cylinder, which transfers force to the arm’s reinforced lugs |
| 4. The box-section structure distributes loads evenly across the arm, preventing localized stress and deformation during digging or lifting heavy materials |
| Core Functions |
1. Transmit hydraulic force to the bucket for digging, lifting, and dumping operations |
| 2. Provide stable support for the bucket during heavy-load tasks (e.g., excavating rock, loading trucks) |
| 3. Maintain precise control of bucket positioning (via coordinated movement with the boom and bucket cylinders) |
| 4. Protect hydraulic components and pivot points from job site debris and wear |
| 5. Ensure long-term structural reliability under cyclic loading (repeated digging/lifting cycles) |
