Conservation, efficiency and a new dump truck

Isaac Quarry has a well-earned and award-winning reputation for its pursuit of environmental excellence and the protection of endangered species.

SINCE IT’S SIMPLE beginning in 1957 the conservation land has expanded to cover some 1100 hectares, including the quarry operation, salmon farm and general grazing and farmland. This conservation effort includes a breeding programme to increase and secure population numbers of endangered species of wildlife.

Against this background, Isaac’s Industries manager Jeff Collins set out to identify efficiencies that could be made in their equipment fleet.

Currently running articulated dump trucks, he figured there had to be a more efficient way to haul gravel on relatively well-formed haul roads. Would it be possible to increase production and simultaneously reduce cost? How about something that was less expensive to buy and to operate? Perhaps with more comfortable ride quality for the operator but without compromising safety?

Iveco Astra presented just the alternative he was looking for. Used extensively in similar applications overseas, the HHD9 is an extra heavy duty off-highway hauler, broadly based on the Iveco road going range, but 2.9 metres wide and purpose built in a dedicated factory producing just these and military vehicles in Italy.

The new 63-tonne truck is an 8×6 drive and has a payload capacity of 41 tonnes. The capacity of the 20 cubic metre rock body is a significant improvement on the 17 three cubic metres of comparable 40-tonne ADT’s. The tipper body is fitted with a wide stabiliser bar underneath to give lateral stability while tipping, and the truck is equipped with an optional ROPS frame extending over the cab to enhance operator safety.

Quarry manager Adam Waite says the company is expanding and upgrading its fleet as part of a major equipment upgrade. “We are trialling this truck to see how efficient it is for us. On paper, there is better fuel efficiency and less ongoing costs.”

Astra was privately founded in 1946 in Italy, and since 1986 has been part of Iveco, itself part of CNH Industrial, and represented in New Zealand by AdvanceQuip NZ.

Along with the Astra range, AdvanceQuip is also the distributor for another CNH brand, CASE Construction Equipment, whose range includes excavators up to 50 tonnes and wheel loaders up to 27 tonnes.

The Astra HHD9 is the largest and most heavy duty off-road vehicle available in the Iveco product line-up. Featuring huge ground clearance, a full-time 8×6 drive with lockable diffs on all axles, and a powerful 540hp engine, the Astra is a true workhorse and excels when road conditions deteriorate.

The engine is the well regarded 13 litre Iveco Cursor engine and it uses ZF’s 16-speed automated transmission to transfer the power to the wheels while Allison fully automatic transmission is available as an option. Downhill performance and safety is enhanced using engine braking and a hydraulic transmission intarder, significantly reducing service brake wear.

Productivity studies carried out by Astra indicate potential TCO (total cost of ownership) savings could be as much as 50 percent, depending on application. This considers factors such as fuel efficiencies, savings on maintenance costs, extra load capacity and improved cycle times.

AdvanceQuip managing director, Steve McLean says this truck has great potential in this market to fill an obvious gap between road trucks and articulated dumpers in off-road applications in quarrying, mining and bulk earthworks.
