Comparing Air Suspension vs. Sprung Suspension on DumpLoada Trailers

Modern Air Suspension from Stronga provides a useful upgrade when compared to traditional steel springs. Durable airbags are made of extra-hard rubber which is designed to perform over many years on the most challenging terrains. Fewer moving parts ensure the equipment lasts longer than the heavier, more-expensive-to-maintain sprung suspension alternative. This premium-level suspension system offers several significant benefits when compared to metal sprung suspension. These benefits are described below.

1. A key benefit of Stronga Air Suspension is the significantly improved comfort enjoyed by the driver. Sprung Suspensions simply do not damp as effectively in harsh environments; especially in DumpLoada heavy material transport operations. Air Suspension damping is especially important with dump trailers due to the high load duties of the trailer.

2. Increasing tractor power, higher speed tractors, bigger trailers and bigger payloads bring new challenges and increased dynamic forces. Stronga Air Suspensions offer an effective way to reduce shock loads. This brings significant useful advantages for operators of Stronga dump trailers.

3. Through our work with leading fleet-owning road building contractors across the globe, Stronga have learnt that Air Suspensions require significantly less maintenance than traditional steel Sprung Suspensions. Owners benefit from significantly less wear and tear on the suspension and associated components.

4. Stronga Air Suspension systems have been developed by BPW over many years working in the harshest environments. They are currently fitted on millions of trucks across the world. Ask yourself; why would the majority of global truck operators choose Air Suspension if it wasn’t proven as the premier system?

5. Ride height control comes as standard when you choose Stronga Air Suspension on DumpLoada trailers, allowing the operator to select the optimal trailer ride height. Setting the Air Suspension to “road-height” on good terrain lowers the trailer’s centre of gravity to improve cornering at high speeds. Enabling “track-height” off-road raises the chassis; this provides optimal articulation and clearance, increasing capability over challenging off-road terrains. During loading cycles, the chassis can be lowered to improve visibility for the loader.

6. With Stronga AirLoada™, the dump trailer automatically releases air from the air bags at the start of each tipping cycle. This greatly improving the stability of the trailer on modern, high capacity dumpers tipping at height, especially on uneven or soft terrain types.

7. Choosing Air Suspension enables you to select other options such as the front Lift Axle. By raising the front axle during empty-travel, the operator enjoys significantly less fuel consumption; a benefit which has become increasingly important for CO² and cost-saving purposes. Moreover, raising the axle also reduces tyre wear over the long term, meaning those expensive replacement costs can be forgotten about.

8. Another great feature enabled by Stronga Air Suspension is Roll Stability Control (RSC). RSC is smart control offered by the WABCO system; it is a function integrated into the steering system to ensure better safety and stability in corners.

9. When you select Air Suspension as your chosen suspension type, you are selecting premium-level BPW equipment which is backed by an extensive global dealer support network. BPW’s famous support service ensures you can source spare parts quickly and reliably whilst enjoying perfect peace of mind.

10. Air Suspension Systems offer a significant saving in tare weight when set against comparable sprung suspensions on tri-axle DumpLoada trailers – all whilst maintaining the exceptional strength and service life operators come to expect from Stronga. This weight saving can be added to the trailer’s payload which is hugely important when working with heavy materials.

Whilst the arguments for choosing Air Suspension are formidable, it may not be a suitable selection for every customer and there are outstanding available alternatives. Premium-quality Hydraulic Suspensions, for example, may be better for some off-road situations whereas Sprung Suspensions do offer credible benefits for others.

It is undoubted, though, that Air Suspension really is the leading solution as we listen to our respected customers who feedback their experiences to us. To learn more, contact our sales team today.
