The tipper truck is the main engineering vehicle for infrastructure, mining and sand transportation. The hydraulic lifting system is the core for unloading work. Many overseas customers encounter slow lifting and weak lifting issues when operating a heavy duty tipper truck. This problem greatly reduces unloading efficiency and delays project schedules. If your tipper truck lifting system responds slowly and cannot reach the full height smoothly, follow the steps below for troubleshooting.https://www.hjtrailer.com/truck/dump-truck/white-light-dump-truck.html
First, check the condition of hydraulic oil. Insufficient hydraulic oil level, deteriorated oil or contaminated fluid will reduce the pressure transmission capacity of the hydraulic pump and cause slow lifting. Open the tank to check the liquid level. If the oil turns dark and muddy, completely replace the hydraulic oil and clean impurities inside the tank to keep the hydraulic circuit clean.
Second, test the hydraulic pump and relief valve. Internal wear of the hydraulic pump leads to insufficient oil supply. If the relief valve pressure setting is too low or its spool gets stuck, pressure will release in advance, and the hydraulic system cannot reach the rated working pressure. Test the system pressure, reset the relief valve pressure according to working conditions, and replace heavily worn hydraulic pumps.
Third, carefully inspect hydraulic pipelines and cylinder joints. Aging hydraulic tubes and damaged seals at joints will cause slight internal or external leakage, which consumes system pressure continuously. It is a common hidden fault that leads to weak lifting of the tipper truck. Check all tubes for oil seepage, tighten loose connectors and replace aged sealing rings.
Pay attention to operation habits. Long-time overloading will continuously damage the whole hydraulic lifting mechanism and repeatedly trigger slow lifting faults. Regular maintenance of the hydraulic system and timely troubleshooting of minor faults can extend the service life of tipper truck hydraulic components, reduce downtime repair costs and ensure stable operation of engineering transportation.
