Wolff Mining, part of the National Group, has been breaking records at BHP Mitsubishi Alliance’s (BMA) Saraji mine, having recently achieving a drilling milestone at the Queensland coal operation.

Wolff Mining is known for its heavy earthmoving capabilities, being a key supplier of heavy earthmoving equipment to the mining sector on a dry hire or wet hire basis, with drilling equipment and services also offered.

For the past 16 months, the company has been assisting BMA Saraji in a “sprint drilling capacity”, providing drilling equipment and full contract mining services.

It currently supplies BMA Saraji with a Cat MD6420B drill with GPS, and provides operational labour such as supervisors, drillers and fitters.

The MD6420B is one of Cat’s heavy-duty drills designed for open-pit mining, delivering reliable performance and operational safety. It is one of the favoured models by drillers around the world and encompasses leading features from the ultra-class to the mid-size rotary drill line, according to Wolff.

Some of the advanced features available include improved fuel efficiency, electro-hydraulic controls that provide increased operator safety and precision, computer-controlled drilling, enhanced diagnostics and autonomous ready functions, it said.

November drilling at BMA Saraji has been undertaken in 270 mm holes ranging in depth from 30-65+ m in tertiary material, according to Wolff.

The company recently achieved a milestone of 43,794 drilled metres (dm) for the month of November, beating the previous record of 41,500 dm at BMA Saraji.

“The performance of our Cat MD6420B drill has been exceptional,” notes Mark Ackroyd, National Group Managing Director. “It is very rare that a drilling company exceeds 40,000 dm a month, so breaking the site record of 41,500 dm at BMA Saraji, and setting a new record of 43,794 dm for the month of November, is a great achievement.”

He added: “To achieve a milestone such as this takes a highly skilled and motivated team and a high-quality piece of mining machinery such as the Cat MD6420B drill. I would like to congratulate the team here at Wolff Mining for their outstanding efforts and praise the performance of the Cat drill.”

National Group, through National Plant & Equipment, has supplied a Liebherr R 9200 excavator to an open-pit gold mine in western New South Wales, Australia.

The Liebherr R 9200 offers the biggest payload in its class with the 12.5 cu.m bucket capacity enabling sustainable performance and peak fuel burn efficiency in the most challenging conditions, according to the OEM.

Equipped with a Cummins QSK38 engine, with a rating of 810 kW at 1,800 revolutions per minute, the R 9200 is available powered by both diesel and electric motors. It can also be fitted with backhoe and face shovel attachments.

National Group Managing Director, Mark Ackroyd, said the arrival of the Liebherr R 9200 had further diversified the company’s already impressive fleet of equipment.

“The feedback from site is that the Liebherr R 9200 has been very well received,” Ackroyd told Australian Mining. “Our customers have been impressed with the performance of the Liebherr R 9200; it’s a very good machine and is competitive with other machines of a similar size and type.”

National Group is known across Australia for its dry hire of heavy earthmoving equipment. Working alongside Liebherr, it selected the R 9200 excavator for site, applying the joint understanding of the mine, the work being completed there and previous success using Liebherr equipment.

Liebherr-Australia Major Account Manager, Ben Kerr, explained: “Liebherr’s relationship with National, and understanding of the gold mine site requirements, allowed us to put forward the appropriate sized excavator and tailored bucket size to suit both National’s and site’s requirements.

“The addition of this R 9200 to National’s fleet further expands their range of mining equipment, building on the strong relationship and ease of doing business between the two companies.”

National Group’s NPE delivers Cat 994K wheel loader to Rio’s Marandoo iron ore site

National Group says its National Plant & Equipment (NPE) subsidiary has delivered Australia’s first rental Cat 994K wheel loader to Rio Tinto’s Marandoo iron ore mine in Western Australia.

After arriving in Perth from the Caterpillar manufacturing facility in Decatur, Illinois, USA, the wheel loader began pre-assembly on February 17 by WesTrac at its Reid Road facility, in WA. From there, the oversized load was disassembled for transportation from Perth to the Pilbara, where final assembly took place on site at Marandoo before being handed over to Rio Tinto to begin work in early May.

Marandoo is one of Rio’s Pilbara iron ore assets to feature autonomy. Back in 2017, Cat and Rio Tinto signed an agreement to retrofit 19 Cat 793F mining trucks for autonomous operation at the site, making it the first fleet of Cat autonomous trucks deployed by Rio Tinto.

National Group said Cat large wheel loaders are well known as the ‘top of their class’ due to their sheer size and durability that ensures maximum availability through multiple life cycles. “The 994K doesn’t disappoint, with a net power of 1,297 kW, an operating weight of over 240 t and a bucket capacity range of 19.1 – 24.5 m³ for hard-rock conditions (up to 43.6 m³ for soft rock), making it the largest wheel loader currently manufactured by Caterpillar,” it said.

Mark Ackroyd, National Group Managing Director, said: “With optimised performance and simplified serviceability, the 994K allows mine sites to move more material efficiently and safely at a lower cost per tonne.

“They are the ideal machine for large mining companies such as Rio Tinto to maximise their efficiency and productivity and reduce the level of ongoing maintenance required.”

Geoff Bailey, WesTrac Executive General Manager of Sales, said: “WesTrac have worked closely with NPE for more than seven years and we’re proud to continue to support the business with industry-leading equipment and technology.

“The 994K can handle large payloads even in tough conditions, loading a matched Cat 789 or 793 haul truck in five to six passes, respectively. It’s a highly efficient option for our WA mining customers.”

Ackroyd said there was currently less than 10 994Ks in Australia, “so we are very excited to own a brand new model and to see it go to work with one of our key clients”.

As many businesses and industries come to a halt due to COVID-19 restrictions, National Group says it is preparing to deliver a range of other machinery to mine sites around Australia in the coming months.

BMA Blackwater coal mine starts up new gen Cat D11 dozer

The first Caterpillar new generation D11 dozer in the world has started work at BHP Mitsubishi Alliance’s (BMA) Blackwater coal mine in Queensland, Australia, according to mining, resources, transport and logistics group National Group.

National Group secured the first of these dozers earlier this month from Cat dealer Hastings Deering as part of an order that would see six of these machines hauled by its National Heavy Haulage subsidiary, the company said.

While the specifics of this new dozer are not yet known, Cat did plan to launch an update to its D11 earlier this year. This would have seen the machine receive new load-sensing hydraulics and new drivetrain components among other additions.

BMA’s Blackwater coal mine, in Queensland’s Bowen Basin, produced close to 2.1 Mt of coal in the most recent September quarter, according to BHP.

In a Hastings Deering release in mid-December, National Group’s Managing Director, Mark Ackroyd, said: “The D11 is the industry’s best large dozer so it was a logical choice for us to bring in six new dozers to add to our expansive fleet.”

Along with load sensing hydraulics reducing fuel burn, the new D11 will extend out component life from fuel burn to overhaul, according to the company. Caterpillar has developed this machine to ensure faster cycle times to produce more dirt at a lower cost per tonne, National Group added.

Ackroyd said the contribution the dozers will add to production and efficiency will boost overall performance on site. “We expect to lower maintenance and repair costs by up to 5% thanks to a new case and frame design, improved bearings, redesigned pin joints, and a 30% larger oil pan.”

Jason Garea, Mining Account Manager at Hastings Deering, said: “There is a single frame now used between both the D11 standard dozer and the carry dozer applications. It’s a beefed-up frame that now does both.”

National Group has lined up all six dozers to be fitted with the new Reclamation blade, or XU Blade, which takes the dozer from a 34 cu.meter blade, to a 42.2 cu.m, according to Garea. “The best thing here is that it still handles like a U-Blade and can go into the same applications. They are far, far more productive which reduces the cost per tonne.”

The second D11 dozer is expected to be commissioned onsite at Blackwater in January.

National Group says it recently acquired Wolff Group, bolting on a range of automated and innovative solutions such as large scale satellite bulk dozer push and semi-autonomous blast hole drilling to its existing range of mining services.

Wolff, the first company in Australia to use Command for dozing, a Cat® Minestar™ offering, also provides contract mining services, excavator pre-strip fleets, civil earthworks, site clearing and rehabilitation works, according to National Group.

The National Group, meanwhile, comprises companies from the mining, resource, logistics and personnel supply industries that, through its National Heavy Haulage and International Global Logistics subsidiaries, regularly delivers mining equipment nationally and internationally.

National Group Managing Director, Mark Ackroyd, sees the acquisition providing niche business opportunities.

“Adding Wolff to the National Group will allow us to deliver additional services in autonomous operations, so it was a logical choice for us,” he said.

“Terry (Wolff, Managing Director of Wolff Group) and his team at Wolff have a very similar organisational culture to ours and that was one of the most important things we spoke about during our discussions. The other was their work in autonomous operations and the focus towards the future of mining.

“We want to provide our customers with the best there is and staying on the cutting-edge of technology goes a long way in allowing us to do that.”

As part of the acquisition, National Group and Wolff have agreed to adopt a “business as usual” approach to ensure minimal to no effect on the current Wolff workforce and customer base, National Group said.

Terry Wolff, who will stay actively involved in the business, said: “National Group met all of our foundations and culturally aligned with the way we already do business here at Wolff, so that made this decision a lot easier for us. We couldn’t think of a better company to pass on the baton to.

“National Group values our people, autonomous expertise and our ability to operate in the segments where we have a depth of knowledge and experience.”

Wolff is well-known in the industry for its focus on innovation and technology and already has an established partnership with Caterpillar and Hastings Deering to implement and optimise semi-autonomous tractor system technology in a world’s-first application into a mining production environment, National Group said.

Ackroyd concluded: “Here at the National Group, we are excited for the future and look forward to further extending the range of automated features for our expansive fleet of dozers and drills.”

The National Group has delivered a pair of new excavators to two coal operations in the Bowen Basin of Queensland, Australia.

The first of these excavators, a Hitachi EX5600 (pictured below), was added to BHP Billiton Mitsubishi Alliance’s Peak Downs site where the National Group previously handed over five Liebherr Ultra-Class T 282C Trucks in September.

The second excavator, a Liebherr R 996B (pictured above), was delivered to its sister mine Poitrel, part of BHP’s other Queensland joint venture, BHP Mitsui Coal. The excavator is the first piece of equipment National Group has at the coal mine.

National Group Founder and Managing Director, Mark Ackroyd, said: “We have been working with BHP for some time now, especially at Peak Downs, so to be adding more equipment there is a testament to the machines we currently have operating for them and speaks volumes of our team on-site who do a great job with maintenance when needed.

“Poitrel, on the other hand, we are very excited to be adding our first piece of equipment there and for it to be the ever reliable Liebherr 996 digger. We’re confident they are going to love this machine and hope it is just the beginning of things to come.”

Bringing such big equipment to this part of Queensland is a complex process. National Group says it has the capabilities to handle all transport, assembly and delivery, giving customers peace of mind when securing these long-term rentals.

Ackroyd said: “We know how difficult it can be to get the bigger gear to Australia first of all, let alone having to worry about everything else once it arrives here. That is why we have worked very hard to build brands that complement each other in the entire journey of port-to-pit.”

National Group is coming off one of its best years to date, it said, however the company has no plans to slow down in 2019 with future plans already to invest in technology and enter the automation space.

Ackroyd said: “The mining industry is now following the technology trend around the world and automation is at the forefront of this. It is all about finding different ways to help your customers succeed and embracing innovation to get that edge over competitors.”
