What Is a Trailer Axle Lift System?
The trailer axle lift system is a smart solution for improving vehicle efficiency. It allows an axle to be lifted when the trailer is partially loaded or empty, reducing road friction, saving fuel, and lowering wear on tires and suspension parts.
How It Works
The system operates using air bellows, sensors, control valves, and actuators. It automatically or manually lifts the axle based on load conditions. The lifted axle reduces rolling resistance, especially during empty runs or in urban areas where tighter turns are needed.
Why It’s Valuable for Fleets
- ✅ Minimizes tire and brake wear
- ✅ Improves fuel efficiency by reducing drag
- ✅ Enables better maneuverability on tight roads
When to Service the System
If you notice slow axle movement, unusual noise, or uneven trailer height, the system may require inspection. Common causes include faulty air bellows or malfunctioning valves. Timely maintenance ensures optimal safety and performance.
