Internal leakage reduces efficiency and stability in concrete pump trucks. Even high-performance models like the 56m SANY used concrete pump truck can face this issue. Routine checks are essential for every used concrete pump truck and Trailer concrete pump truck.
Leakage occurs due to worn seals, contaminated hydraulic oil, overloading, and lack of servicing. Early signs include pressure inconsistencies, foaming oil, reduced stroke power, and abnormal vibrations.
Diagnostic steps involve hydraulic pressure monitoring, seal inspections, oil quality tests, and cylinder performance checks. Preventive care requires seal replacements, oil filtering, operator training, and regular servicing schedules.
By following these steps, companies extend the service life of 56m SANY used concrete pump truck fleets while improving safety and lowering repair expenses.
