- Key functions & working principle
| Working Principle |
1. When the hydraulic pump is activated, it pressurizes hydraulic oil and pushes it into the 421-03-32121 hose through the inlet fitting |
| 2. The steel wire braid reinforcement counteracts the internal pressure, keeping the hose’s inner tube from expanding or failing |
| 3. The flexible hose routes pressurized oil to actuators (cylinders/motors), accommodating movement of lift arms/swing mechanisms without restricting flow |
| 4. The outer cover shields the inner layers from external damage, while the NBR inner tube prevents oil contamination and leakage |
| 5. Pressurized oil exits through the outlet fitting to power equipment functions (e.g., lifting the loader bucket) |
| Core Functions |
1. High-Pressure Oil Conduction: Transmits pressurized hydraulic oil to power critical equipment movements (lift, tilt, swing) – ensures responsive operation under heavy loads |
| 2. Leak Prevention: Factory-crimped fittings and durable inner tube eliminate oil leaks, avoiding pressure loss and safety hazards (slippery job site surfaces) |
| 3. Abrasion Protection: Outer cover resists physical damage, extending hose service life in debris-prone environments |
| 4. Vibration Absorption: Flexible design absorbs engine/equipment vibration, reducing stress on fittings and mating components |
