Today, demand for air springs utilised in air suspensions for all types of heavy vehicles (including a vigorously growing market for 4WDs and recreational vehicles) has grown in line with a world market that is now estimated by market researchers to exceed AU$6 billion. Good basic maintenance is the key for these almighty tough air springs to last for hundreds of thousands of kilometres - in well-maintained cases, out past 600,000 km, in our experience. After all, air suspensions are the ride of choice for many of the top models of the world’s prestige makers of limousines, so our truckies are in good company as they suffer less fatigue through road shock.Īnd the industry (and the regulators) quickly woke up to the fact that these suspensions could be kinder to the roads, as well as to them - while delivering heavyweight reliability where they are properly maintained.

Air suspension was a quiet revolution (literally) that brought massive relief to a whole generation of drivers who appreciated the benefits of the technology through the seat of their pants, because air suspensions were far smoother compared with the harsher, clumsy systems that were commonplace on heavy vehicles at that time. They were certainly tough, these steel springs, but they were hard too on roads, cargoes and drivers. Use of air suspension is a far cry from even 30 years ago, when they were more of a rarity than the norm, which comprised massive, bone-jarring, steel springs.

Suspensions on the list encompass the major original equipment manufacturers (OEM) and specialist brands of worldwide manufacturers, including in Australia. Air suspension systems now abound in the federal government’s lists of Certified Road-Friendly Suspensions prepared by the Department of Infrastructure, Transport, Regional Development and Communications. Use of these tough but comfortable systems - which also reduce noise and vibration - has grown exponentially over a generation in Australia, to the point where they have gone from being a comparative rarity to becoming an industry standard as drivers and fleet owners seek top performance on both sealed and tough unsealed roads (the latter of which still comprise more than half the total of the roads in this sprawling country). Most of the heavy trucks - certainly most of those over 12 tons - rely on road-friendly air suspension systems that increase the ability of trucks, trailers and coaches to transport loads by levelling the suspension, enhancing stability, control and safety. These vital vehicles, with an average age of about 15 years, share the roads with about 20 million cars and other vehicles of different types. Our heavy vehicle fleet now stands at about 365,000 rigid trucks over 4.5 tons, according to the 2021 ABS Motor Vehicle census, with another 109,927 articulated heavy vehicles (also a record number) doing the heavy haulage over Australia’s diverse and demanding network of more than 870,000 km of public roads. The airbag revolution rolls on with this nine-point preventive maintenance checklist for heavy vehicles - designed to keep road-friendly air suspension working safer for longer across Australia’s road transport network.Īs the Australian heavy vehicle fleet nudges half a million trucks for the first time on record, a huge emphasis is being placed on their safety as road users and as a vital link in the nation’s response to COVID-19 supply issues.
