This diagram explains how a dump truck uses a hydraulic system to lift and empty its heavy cargo bed.The 6-Step Flow Sequence1. Engine Power: The truck engine provides mechanical movement and power.2. PTO (Power Take-Off): The PTO unit takes power from the engine or transmission to run the hydraulic pump.3. Hydraulic Pump: The pump turns mechanical power into a high-pressure flow of hydraulic oil (150–300 bar).4. Control Valve: A manual lever on the valve directs the oil flow to either lift or lower the dump body.5. Hydraulic Cylinder: Pressurized red oil fills the telescopic cylinder, forcing it to extend upward and raise the bed.6. Tipping: The dump body tilts completely to slide the cargo out. Afterward, oil returns through the blue line back to the tank to lower the bed.
