Hydraulic System Specifications

The hydraulic system is what gives the Hyundai R300LC-9S its muscle, controlling everything from the boom and arm to the bucket. It’s super important to understand how this system works to really appreciate the excavator's capabilities.

Pump Type and Flow Rate

The hydraulic pump is the heart of the hydraulic system, responsible for generating the pressure needed to power the excavator's various functions. The flow rate determines how quickly these functions can be performed.

• Pump Type: The Hyundai R300LC-9S typically uses variable displacement piston pumps. These pumps adjust the flow rate based on the demand, improving efficiency and reducing energy waste. They are known for their reliability and ability to maintain consistent performance under varying loads.
• Flow Rate: The main pumps usually provide a combined flow rate of around 152 gallons per minute (575 liters per minute). This high flow rate ensures quick and responsive operation of the excavator's hydraulic functions, enhancing productivity.

Hydraulic Pressure

The hydraulic pressure dictates the force that the excavator can exert. Higher pressure means greater digging and lifting capabilities.

• System Pressure: The main hydraulic system operates at a pressure of approximately 5,000 psi (345 bar). This high pressure allows the excavator to handle tough digging conditions and lift heavy loads with ease.
• Pilot Pressure: The pilot system, which controls the main hydraulic valves, typically operates at a lower pressure, around 550 psi (38 bar). This ensures smooth and precise control of the excavator's movements.

Hydraulic Cylinders

The hydraulic cylinders are responsible for converting hydraulic pressure into mechanical force, powering the boom, arm, and bucket.

• Boom Cylinders: The boom cylinders are large and powerful, providing the lifting force for the excavator. They are designed to withstand high pressures and heavy loads.
• Arm Cylinder: The arm cylinder controls the movement of the arm, allowing the operator to dig and reach efficiently.
• Bucket Cylinder: The bucket cylinder controls the digging and dumping action of the bucket. It is designed for precise control and high breakout force.

Hydraulic Oil Capacity

• Hydraulic Oil Capacity: The hydraulic oil reservoir usually holds around 79.3 gallons (300 liters). This large capacity ensures that the hydraulic system remains properly lubricated and cooled, preventing overheating and extending the life of the components.

Dimensions and Weight
