Function of High Gear and Low Gear
High Gear (Fast Speed Mode):
Used for long-distance concrete pumping or when higher output is needed.
Provides higher delivery speed (larger output, usually 20–40 m³/h).
Suitable for large-area spraying, thick layers, or less complex sections.
Low Gear (Slow Speed Mode):
Used for precise spraying, shorter distances, or difficult angles (like in tunnels or slopes).
Offers lower output but more stable flow (smaller output, e.g., 10–20 m³/h).
Improves control and reduces rebound during detailed or thin-layer spraying.
Advantages
Flexible operation for different site conditions
Reduces wear on components by using proper gear per task
Saves energy when high pressure isn't required
Improves concrete quality through better flow control
Example Application
In a tunnel project, use low gear when spraying the tunnel crown for accuracy.
Switch to high gear when transporting concrete from the mixer truck to the working face.
