MAX100 operation manual: the air suspension & lift axle

The air suspension helps keep the semi-trailer level, regardless of load weight, reducing wear on both the trailer and cargo. Air suspension also improves road handling, providing a smoother ride by adapting to road conditions. The lift-axle means that an axle can be raised or lowered as needed. When the trailer is fully loaded, the lift axle is lowered to spread the weight, reducing wear on the main axles and helping meet axle load regulations. When the trailer is empty or lightly loaded, the lift axle is raised, saving fuel and tire wear.
