3. Working Principle
4. Installation & Matching Key Points
Mounting position: Prioritize the right-side PTO port (sufficient installation space); left-side option available for partial vehicle models.
Hydraulic pump matching: Adopt 6-spline / flange interface; working pressure ≤16MPa, flow rate ≤50L/min (suitable for light truck dump applications).
Control system: Pneumatic type is commonly used for light trucks (connected to vehicle air storage cylinder), equipped with PTO control switch and indicator light.
Gear ratio selection:
High speed: Ratio 0.9~1.0 (high pump speed, for sprinkler operation)
Low speed & high torque: Ratio 1.1~1.2 (high torque, for dump lifting operation)
