What is the Working Principle of the Hydraulic System in the SANY SCC800TB Telescopic Crawler Crane?

The hydraulic system in the SANY SCC800TB telescopic crawler crane is essential for its operation, providing the force necessary for lifting, movement, and other tasks. Let’s break down the working principle of this complex hydraulic system.

1. Hydraulic Pump

The heart of any hydraulic system is the pump. The SANY SCC800TB uses a powerful pump that transforms mechanical energy from the engine into hydraulic energy. This hydraulic fluid is then transported throughout the system to power various operations.

2. Control Valves

Control valves manage the flow of hydraulic fluid, directing it to the necessary areas of the crane for different tasks. These valves give operators the ability to control the boom, extend or retract the arm, and maneuver the crawler tracks with precision.

3. Hydraulic Cylinders

Hydraulic cylinders are critical components that convert hydraulic fluid pressure into mechanical motion. These cylinders are responsible for the extension and retraction of the crane’s telescopic arm, which allows it to reach and lift heavy loads effectively.

4. Hydraulic Fluid Circulation

The hydraulic fluid, which powers the entire system, is circulated through pipes and hoses that connect various parts of the crane. This fluid must remain at a certain pressure to ensure the system runs efficiently, activating the boom, winch, and track drive system when required.

5. The Importance of the Hydraulic System

Understanding the hydraulic system’s operation is crucial for operators, as it directly influences the crane’s performance. Proper maintenance and understanding of the system ensure the crane operates efficiently and safely in various environments, such as construction and mining projects.
