Common Operational Issues & Solutions
Boom Operation Failures
Potential Causes:
Insufficient hydraulic pressure, air in pipelines, faulty control valves, or worn/loose boom components.
Recommended Solution:
Check for hydraulic leaks, bleed air from system, repair/replace valves, and service worn components.
Pumping Pressure Fluctuations
Potential Causes:
Variable concrete slump, pipeline blockages, or worn pumping components.
Recommended Solution:
Maintain consistent concrete mix, clean pipelines regularly, and replace worn pistons/seals.
Chassis Vibration & Noise
Potential Causes:
Unbalanced tires, loose chassis components, or suspension system issues.
Recommended Solution:
Balance tires, tighten all chassis connections, and inspect suspension system.
Note: For complex technical issues, contact authorized service technicians to ensure safe operation and proper maintenance.
