- Key functions & working principle
| Working Principle |
1. One leaf plate is bolted to the fixed equipment frame (e.g., cab frame, engine compartment); the other is bolted to the movable door/panel. |
| 2. The chrome-plated pivot pin connects the two leaf plates, enabling rotational movement (0–180°) of the door/panel. |
| 3. Bronze bushings (if fitted) reduce friction between the pin and leaf plates, ensuring smooth rotation even under load. |
| 4. Periodic lubrication via the grease fitting flushes out dirt/debris and maintains a protective film on the pin, preventing seizing and wear. |
| 5. The corrosion-resistant coating protects the hinge from rust and chemical damage, ensuring long-term functionality. |
| Core Functions |
1. Structural Support: Bears the weight of heavy metal doors/panels (e.g., cab doors, engine covers) while enabling easy opening/closing for maintenance. |
| 2. Smooth Rotation: Low-friction pivot pin and bushings allow effortless operation of doors/panels, even after prolonged use. |
| 3. Vibration Resistance: Maintains structural integrity under continuous machine vibration, preventing loosening or failure that could trap technicians or damage equipment. |
| 4. Corrosion Protection: Coated steel construction resists rust and chemical damage, extending service life in harsh environments. |
| 5. Safety: 180° opening angle ensures unobstructed access to critical components, reducing maintenance time and injury risk. |
