The Main Functions of Air Springs in Agricultural Sprayers

1. Shock Absorption and Cushioning

Machine Protection: Large sprayers are subject to significant bumps and vibrations when operating in rugged fields. Air springs effectively absorb and cushion these impacts, protecting the sprayer's main beam, boom, hydraulic system, and precision components, reducing failure rates and repair costs.

Crop Protection: A smooth ride reduces damage to crops caused by the machine, especially in mid- to late-stage crops.

2. Maintaining a Level Chassis

Constant Ground Clearance: Regardless of the sprayer's load (a full tank can vary by several tons from empty), air springs automatically maintain a stable chassis height by adjusting internal air pressure.

Ensuring Operational Stability: A level chassis ensures the boom maintains a predetermined height above the ground, which is crucial for uniform spraying. If the chassis tilts, with one side of the boom higher than the other, uneven spray distribution will occur.

3. Improved Operator Comfort

For modern sprayers with comfortable cabs, air spring suspension significantly reduces vibration and noise transmitted to the cab, alleviating operator fatigue and improving efficiency and safety during extended operations.

4. Protecting the Boom System

This is one of the most critical functions. The boom is connected to the chassis via a linkage or directly. Severe vibrations can be directly transmitted to the boom, causing:

Mechanical damage: Fatigue and fracture of the boom structure.

Degraded spraying quality: Violent up-and-down movement of the boom can cause overlapping or missed sprays, seriously impacting spraying results.
