This diagram illustrates the lift and tilt hydraulic system of a wheel loader, showcasing how pressurized oil is routed to actuate specific components.Pressure Management: A gear-type hydraulic pump draws oil from the tank to generate high pressure, which is then directed by the main control valve to actuate the lift and tilt cylinders.System Protection: The main relief valve safeguards the system against excessive pressure, while the suction strainer and return line filter maintain oil cleanliness to prevent component wear.Cooling and Lubrication: Hydraulic oil is routed through a front-mounted oil cooler to dissipate heat generated during operation before returning to the tank.
