Choosing the Perfect Suspension for your Slurry Tanker

Why Suspension is Important

Why? Well without suspension every bump, pothole, or uneven terrain would be directly transmitted to the tank and tractor. This can lead to excessive vibrations, compromising the structural integrity of the tanker and causing unnecessary stress on components.

A well-designed suspension absorbs shocks, improves stability, and ensures a more comfortable and controlled ride. It also helps distribute the weight evenly, reducing strain on tires and axles. Ultimately, a reliable suspension system enhances the longevity and reliability of your slurry tanker, making it a worthwhile investment.

With Nevada you have a number of suspension options depending on your needs.

Leaf Spring Axle Suspension

Leaf Spring Axle Suspension is standard on all tandem and tridem slurry tankers. It is available on single axle models, however this is rarely any advantage on smaller slurry tankers. Smaller models generally only require axle suspension when used in extremely rocky and uneven ground.

Leaf Spring Axle Suspension is the traditional suspension system found in many slurry tankers. It consists of a series of stacked, curved metal strips (leaves) bound together by brackets. This setup provides excellent load-carrying capacity and durability, making it suitable for heavy-duty applications. Leaf Spring Axle Suspension is also cost-effective and easy to maintain, with readily available spare parts.

Leaf Spring Drawbar Suspension

Leaf Spring Drawbar Suspension is standard on Nevada Slurry Tankers that include auto-filling arms (usually 10,000L+).

Leaf Spring Drawbar Suspension is a variant of the leaf spring suspension system specifically designed for the drawbar of the slurry tanker. This type of suspension provides excellent load-carrying capacity and stability, ensuring that the weight is evenly distributed between the drawbar and the axles. Leaf Spring Drawbar Suspension is known for its robustness and durability, making it suitable for heavy-duty applications where the drawbar is subjected to significant stress. It offers reliable performance and ease of maintenance, with readily available spare parts. However, similar to the Leaf Spring Axle Suspension, it may provide a stiffer ride compared to other suspension types.

Hydraulic Axle Suspension

If you’re after a more consistent ride quality, less wear and reduced maintenance, then hydraulic axle suspension may be the way to go.

Hydraulic Axle Suspension employs hydraulic cylinders and dampers to cushion the slurry tanker. This system offers superior shock absorption, providing a smoother ride and reducing stress on the tanker’s structure. Hydraulic Axle Suspension adjusts automatically to varying loads, ensuring consistent performance regardless of the tank’s content level. It also allows you to lower the tank’s entire centre of gravity for better performance over hilly ground.

A further option available is the ability to lift the front axle off the ground while travelling with an empty tank. This prevents unnecessary wear on the tyres.

While Hydraulic Axle Suspension generally offers a more comfortable ride, it may require periodic maintenance and occasional hydraulic fluid checks.

Hydraulic Drawbar Suspension

Hydraulic Drawbar Suspension utilises hydraulic cylinders and dampers to absorb shocks and vibrations on the drawbar. This suspension system offers superior ride comfort and reduces stress on the slurry tanker’s structure during transport. Hydraulic Drawbar Suspension automatically adjusts to varying loads, ensuring stability and consistent performance. It is especially beneficial when hauling sensitive or valuable payloads that require extra care and protection. While Hydraulic Drawbar Suspension provides enhanced comfort and load management, it may require periodic maintenance and occasional hydraulic fluid checks.

Air Axle Suspension

Air Suspension provides the ultimate ride quality and is the best option if your tractor has air connections. This is the next step up from hydraulic axle suspension, further reducing wear on the machine and resulting in less maintenance and longer life.

Air Suspension utilises air springs or airbags to support the weight of the slurry tanker. Compressed air is pumped into the airbags, allowing for adjustment based on the load. This suspension type offers excellent shock absorption and superior ride comfort. Air Suspension adjusts automatically, ensuring optimal ride height and load distribution. It also provides the advantage of customizable firmness and flexibility, allowing the driver to tailor the suspension to specific road conditions. However, air suspension systems are typically more expensive upfront and may require occasional maintenance, including airbag inspections and compressor checks.

Choosing the Right Suspension

Selecting the ideal suspension for your slurry tanker depends on various factors, including your specific application, budget, and personal preference. If you require a reliable and cost-effective solution for heavy-duty use, Leaf Spring Axle Suspension is a solid choice. For those prioritising a smoother ride and precise load management, Hydraulic Axle Suspension offers exceptional performance. And if your hauling involves long distances or rough terrains, the superior comfort and flexibility of Air Suspension may be the way to go.
