What should be inspected if a trailer has an air suspension system?

If a trailer has an air suspension system, the crucial aspect to inspect is the air supply and pressure thresholds. Air suspension systems rely on a controlled supply of air to maintain the proper ride height and to absorb shock effectively. The air pressure within the suspension system must be at the correct levels to ensure stability, comfort, and safety while the trailer is in operation. An inspection focused on the air supply and pressure thresholds checks for leaks, the functionality of the compressor, and whether the system can maintain the required pressure under load. This is essential for ensuring that the trailer operates efficiently, without risking sagging or bouncing, which could lead to handling issues or premature wear on the suspension components.

Other aspects like height adjustments and capacity, load ratios and patterns, or overall weight distribution, while important, do not address the immediate necessity of ensuring the air suspension system functions correctly through adequate air supply and pressure management. Thus, inspecting the air supply and pressure thresholds is fundamentally vital for the operational integrity of air suspension systems in trailers.
