Race over rough haul roads at full speed comfortably. Lower your cost per tonne dramatically.
Discover the unique benefits of our fully hydraulic suspension for articulated haulers.
Most haulers have to slow down as soon as the road gets rough. Not so with full suspension. It efficiently cancels out any disturbances, so you can step on the gas rather than on the brakes. When you drive empty on a rough haul road it really comes into its own, allowing you to increase your speed from 13 km/h (8 mph) to 52 km/h (32 mph) with the same level of comfort and control. It’s one of those things you have to experience for yourself to believe.
Operators love Volvo full suspension haulers. And no wonder. They eliminate the shocks, vibration and noise so commonly associated with driving off-road. This increases the driving comfort, saving you from repetitive strain injuries in the long run, while keeping you alert and in control throughout the workday. Plus, a smoother ride is easier on both the road and the hauler – reducing unnecessary maintenance costs.
Since we launched full suspension in 2007, it has proved to be a reliable system for the toughest of driving conditions. Many mining and quarrying companies worldwide have praised the unique technology for the benefits it has brought them in productivity and operator comfort. All while being just as durable and dependable as a traditional suspension.
By switching to full suspension, you might be able to do the same job with fewer machines, decreasing your total cost of ownership by up to 13%.
The below example shows how replacing conventional suspension haulers (A45G) with full suspension haulers (A45G FS) can have a large effect on your business. It’s based on a fleet of 16 articulated haulers, with a total haul cycle of 3.1 kilometers (1.9 miles).
Full suspension is a fully hydraulic system. It works by supplying hydraulic fluid to the suspension cylinders. Oil is free to flow to and from the tank as needed, unlike with gas hydraulic cylinders.
The front suspension consists of two hydraulic cylinders (1) and two accumulators. The bogie beam and rubber springs have been replaced with four hydraulic cylinders coupled with four accumulators (2) working in pairs – two high-pressure pairs for loaded operations and two low-pressure pairs for unloaded operations.
Six level sensors (3) monitor the frame movement in relation to the axles and signal the hydraulic system to adjust the suspension dynamically.
Whether you work in mining, quarrying or heavy infrastructure projects, the A45G FS will get the job done efficiently, comfortably and productively in extreme off-road conditions.
