The top screen is linked to a colour wide-angle rearview camera mounted on the chassis and shows the apron of the scraper, whilst an identical screen to the left-hand side of the cab shows an in-bowl view.
The placement of the screens and the excellent large
mirrors on the Volvo mean the operator very rarely needs to take a look over their shoulder at what is going on behind them. An operator of one of the outfits, Ian Hagler, praises the combination for its performance: “We’ve run it on top soils and hard, compacted, former colliery overburden and it performs very well. You have to be very careful and not be too greedy as it will make the wheels spin but with a shove from the blade, you soon get moving again. I was a bit wary about operating the combination at first but after a couple of days, it became second nature and is very easy and comfortable to operate.”
Stuart is extremely pleased with the new combination’s performance and is keen to add that the production figures are far exceeding his and the company’s expectations. Whilst wanting to keep the exact figures close to his chest, he did say that to move the equivalent amount of material as quickly as these combinations do, he would require at least a trio of 35- tonne dump trucks, a 45-tonne excavator and a dozer on the fill area. That’s five lots of fuel, five operators and five machines compared to the three they are currently using. Stuart sums up, “The trucks do use a little more fuel than they normally would but they are carrying over 40 tonnes at a time. This equates to over a 40% increase in material moved every time the truck moves. We couldn’t be more pleased with this result.” ■

“We wouldn’t look at a job without it being undertaken on GPS these days. The accuracy and speed at which we can undertake a project are amazing. We no longer move too much or too little material and not having a surveyor on the ground makes the job so much safer.”
The multi-function joystick allows control over the raising and
lowering of the bowl, opening and closing of the apron as well as the actuation of the ejector plate.
To the operator’s right hand side are a trio of screens including the control screen for the scraper box, a real-time view of exactly where and what the outfit is doing and a colour wide-angle rearview camera which shows the apron of the scraper.
