(1) Large Tractors and Harvesters:
Hyperbolic air springs adjust internal air pressure to accommodate varying loads, reducing vibration transmission in rugged farmland, protecting delicate components (such as the engine and transmission), and reducing driver fatigue.

Advantages: Compared to traditional steel springs, they offer over 30% improved shock absorption and can dynamically adjust vehicle height to prevent chassis contact due to load fluctuations.

(2) Seeders and Fertilizer Spreaders:
During high-speed operation, the flexible support of air springs reduces seed bounce and displacement, ensuring uniform seeding. In fertilizer spreaders, they cushion fertilizer tank sway and prevent clumping.

(1) Agricultural Product Transport Trailers:
Air pressure adjustment allows them to adapt to varying cargo weights (such as grain and fruits and vegetables), preventing damage caused by bumps during transport.

Data Support: A USDA study shows that trailers equipped with air springs can reduce the loss rate of fruit and vegetable transport by approximately 12%.

(2) Automated Warehousing Robotic Arms:
In agricultural product sorting lines, air springs are used to cushion the impact of sudden stops on robotic arms, extending equipment life.
