- Key functions & working principle
| Working Principle |
1. Fixed leaf is bolted to the equipment’s stationary structure (e.g., cab frame, engine compartment); rotating leaf is fastened to the movable component (e.g., door, hood) |
| 2. The pin inserts through aligned holes in both leaves, enabling the movable component to rotate open/closed |
| 3. Bushings (if equipped) reduce friction between the pin and leaves, ensuring smooth, quiet movement |
| 4. Heat-treated materials and corrosion-resistant coating maintain structural integrity under vibration and environmental stress |
| Core Functions |
1. Enable smooth, controlled rotation of movable components (cab doors, hoods, access panels) for operator entry and maintenance |
| 2. Securely fasten two components while accommodating rotational movement |
| 3. Withstand vibration and minor impacts to prevent component damage or misalignment |
| 4. Resist corrosion and wear to ensure long-term reliability in construction environments |
