Application of Air Springs

Construction machinery: shock absorption and precision protection
Construction machinery (such as cranes, excavators, concrete pump trucks) are subjected to severe vibrations during operation, which may damage the precision hydraulic system or affect the positioning accuracy. Air suspension absorbs impact energy by dynamically adjusting the air pressure.

Typical applications
- All-terrain cranes: When the telescopic arm is operating, the air suspension offsets the load swing and improves the hoisting stability.
- Mining dump trucks: Protect the chassis and electronic control system under heavy load and bumpy road conditions.
- Technical advantages:
- Actively adjust stiffness/damping to adapt to different working conditions (such as the travel vs. operation mode of the excavator).
- Reduce the vibration transmitted from the equipment to the ground, meeting the requirements of environmental protection construction (such as nighttime operation in the city).

2. Agricultural machinery: terrain adaptation and driving comfort
Large agricultural machinery (such as tractors with more than 300 horsepower and combine harvesters) needs to reduce the body tilt in soft or uneven farmland to avoid driver fatigue and protect crops.

Typical applications
- High-clearance sprayers: air suspension maintains constant ground clearance to prevent crops from being crushed.
- Sugarcane harvesters: automatic leveling when working on slopes to reduce sugar loss.
- Technology extensions:
- Combine GPS with terrain pre-scanning system to pre-adjust suspension parameters (such as John Deere's "AutoTrac" system).
- Suspended cabs further isolate high-frequency vibrations (such as Kubota harvesters).
