Excavator hydraulic hose vibration may be caused by the following reasons:
- Aging or wear of the hose: After prolonged use, hydraulic hoses may age or wear, leading to thinning of the hose walls or cracks, thus causing vibration. Damaged hoses should be replaced promptly.
- Loose hose connections: Threads or joints at the excavator’s hydraulic hose connections may become loose, causing vibration during operation. Check and tighten hose connections to ensure they are secure and not loose.
- Unstable hydraulic system pressure: Improper pressure regulation or malfunction in the hydraulic system can lead to unstable hose pressure, causing vibration. Check the hydraulic system’s pressure regulator to ensure stable pressure.
- Excessive excavator workload: If the excavator’s workload exceeds the hose’s capacity, excessive vibration may occur. When using the excavator, ensure the workload is within the hose’s rated range.
- Foreign objects or deposits inside the hydraulic lines: Foreign objects or deposits inside the hydraulic lines can obstruct the flow of hydraulic fluid, leading to unstable pressure and causing vibration. Regularly clean the hydraulic lines to keep them clean.
If the excavator’s hydraulic lines vibrate severely or persistently, it is recommended to have a professional inspect and repair them to ensure the normal operation and safety of the hydraulic system.
