Artisan battery-powered Z50 truck on its way to Kirkland Lake’s Macassa gold mine

Kirkland Lake Gold says it is expecting to receive a 50 t battery-powered Z50 underground haul truck at its Macassa gold mine, in Ontario, Canada, this quarter, following a purchase agreement signed last year.

The gold miner’s Macassa operation has been a leading adopter of new electric equipment and already has four 40 t battery-powered machines at the underground mine. These are matched by many battery-powered LHDs made by likes of Artisan Vehicle Systems and Epiroc.

The latest 50 t vehicle will come from Artisan, a Sandvik Mining and Rock Solutions business unit.

The Z50 haul truck is a ground-up design that seamlessly integrates the most capable and proven battery-electric powertrain available in the mining industry with the latest and most coveted features of any haul truck on the market today, according to Sandvik. The 50 t machine is based off the existing design for the Z40 truck, which Artisan released back in 2018, but features a stretched rear frame (close to 19 in).

It is equipped with AutoSwap, a patented self-swapping system for the Artisan battery pack. This makes battery swapping faster and easier with a minimum amount of manual handling: changing the battery only takes about six minutes, and it can be done in a passing bay or old re-muck bay with no overhead cranes or external infrastructure needed, Sandvik says.

The news of the pending arrival of this electric vehicle came at the same time as Kirkland Lake released its 2020 production results. The company produced 369,434 oz of gold in the December quarter to make a total of 1.37 Moz of gold in 2020, 41% higher than the total in 2019, which was in line with its full-year 2020 guidance of 1.35-1.4 Moz.

Tembo 4×4 e-LV expands battery-electric retrofit range

Tembo 4×4 e-LV has added a new option to its line-up of battery-powered equipment for the underground mining industry, with an extra-large 10 personnel carrier joining the portfolio, according to one of its distributors.

The new conversion kit is specifically targeted for applications where a maximum number of people are required to be transported at once.

The more spacious supervision vehicle option, which comprises forward-facing six personnel carrier, will also be available as a battery-electric conversion kit.

Last year, Tembo signed an agreement with the GHH Group to include the electric off-road light duty vehicles within its product offering and its worldwide sales and service program. As part of the agreement, GHH offers the vehicles in Germany, Turkey, Greece, Russia, India, the USA, Mexico, Chile, New Zealand, South Africa, Botswana, Mozambique, Namibia, Tanzania, Zambia, Zimbabwe, the CIS states and Latin America.

The conversion kits are for both mechanical and electrical service vehicles, which are based on the enhanced, flatbed platform designed to take any special equipment like a crane or workshop machinery or service equipment for servicing mining machinery, GHH says.

The first Tembo Electric Cruiser came on the market in 2016. The company’s approach to turning the Toyota Land Cruiser and Hilux series into fully-fledged electric multi-purpose vehicles, especially for construction and mining industries, has been well received, with Boliden’s Tara mine, in Ireland, the first to trial one of its ‘green’ machine.

The Tembos correspond largely to the series standard of Toyota, but are equipped with an electric motor with 65 kW of power and 250 Nm of torque, a special 1:3 transmission and a powerful battery designed for at least 10 years or 8,000 charging cycles. They can achieve 80 km run time with a 28 kWh battery pack and 200 km with a 72 kWh battery pack.
In two-and-a-half hours the vehicles are charged from 20% to 80% with the single-phase charger. Using a three-phase charger, this charge time decreases to only one hour.

No external infrastructure is required for operation as a 15 kW charger is also on board with the single phase and a 22 kW with the three phase. Battery recuperation is in place and a charging cable wallbox can also be supplied with the vehicle, if required.

The vehicles reach a top speed of 80 km/h and can climb gradients of up to 45°, GHH says.

Tackling the big mine electrification questions

“There is consensus in the industry that once we start doing electrification, we will innovate much more in other areas of the mining space.”

If anyone in the mining sector thought electrification was not in their wheelhouse, Theo Yameogo’s words might make them think again.

Yameogo, Partner and National Mining & Metals Co-Leader at EY Canada, made such a statement during The Electric Mine Virtual Conference earlier this week. The event, organised by International Mining Events, brought leaders in the electrification space together to discuss the latest developments in the industry, of which there were many.

The stage was set for mine electrification reveals, and Henrik Ager, President of Sandvik Mining and Rock Technology (soon to be Sandvik Mining and Rock Solutions), did not disappoint, acknowledging that the company is currently working on development of what would be its largest underground truck: a battery-powered 65 t vehicle.

This was all part of the company’s aim to have a “full range electrified offering by 2022”, he said.

Azizi Tucker, Co-Founder and CTO of XING Mobility, was next up, providing an overview of the Taiwan-based company’s offering in his presentation: ‘Electrification from prototype to mass production’.

With a remit to provide commercial, industrial and specialty vehicle makers with modular, high power and safe battery and powertrain technologies, XING is making an entrance into the mining space at just the right time.

Tucker talked attendees through the elements that make the company’s IMMERSIO™ battery solutions ideal for the mining sector: “With the modular size and shape of our batteries, we can really suit any vehicles. We find this very popular with the original equipment manufacturers (OEMs) as they can utilise their existing chassis.”

The elimination of corrosion, ability to operate consistently in high-temperature environments, a variety of sealing techniques and the use of nickel-manganese-cobalt lithium-ion chemistry has allowed the company to provide the safe and enclosed battery solution miners are looking for.

He concluded by saying XING was in conversation with a variety of mining companies, mining OEMs and mine site operators about deploying solutions in the space.

Attendees were then treated to a demonstration of Tembo 4×4 e-LV’s Electric Cruiser via video during the session: ‘Green conversions: the Tembo 4×4 e-LV electric light utility vehicle platform’ (pictured below). They got up close and personal with the battery-electric utility vehicle as it travelled on- and off-road close to the company’s Netherlands HQ.

After a 15-minute demo showing off the Electric Cruiser’s attributes, Paul Smeters, Tembo 4×4 e-LV’s Marketing Manager, and Alexander Haccou, Tembo 4×4 e-LV’s Technical Director, joined the event to answer audience questions.

The inevitable query came up early during the live Q&A: have you tested this vehicle in an underground mine?

Haccou was prepared for this, explaining that Boliden’s Tara underground zinc-lead mine in Ireland was the first recipient of the company’s Electric Cruiser, and a unit had been operating there for a few years now observing many of the maintenance benefits battery-electric machines are becoming renowned for.

The Electric Cruiser has also been tested in Australia and Canada with the help of Tembo 4×4 e-LV partners in those regions, he added.

“We don’t use fast charging or battery swapping,” Haccou said in response to another question. “What we have seen in several mines is the daily amount of usage is less than the battery’s full capacity.”

After several questions related to an active thermal management system for batteries had come up in previous sessions, Nicolas Champagne’s entrance to the virtual event proved timely.

His presentation, ‘Battery thermal management system using a highly advanced dielectric fluid’, homed in on the use of a dielectric fluid with specific features to allow direct cooling of the battery electrochemical cells.

Champagne, Formulation Team Manager of the R&D department for TOTAL Lubricants, revealed results from use of the fluid in bench tests and simulations at the battery pack level, extrapolating what these results could mean for battery-powered vehicles in the mining sector.

He said the company is in discussions with at least one mining customer about deploying its fluid on a battery-powered vehicle.

After previous sessions had discussed the potential for fast charging and battery swapping, Champagne made clear that TOTAL Lubricants’ solution would prove beneficial in all battery-powered applications throughout the mining sector.

 

Following a lunch break, it was the turn of Epiroc’s Anders Hedqvist (Vice President of R&D, underground) and Franck Boudreault (Electrification Transformation Lead, underground) to deliver a scoop (pun intended).

The pair, during their presentation, ‘From one generation to the next – learnings from zero emission mining’, took it in turns to provide updates.

Boudreault revealed the company’s plan to create battery-electric conversion kits for not only Epiroc diesel-powered equipment out in the field but other OEMs’ machines, before Hedqvist disclosed the company’s in-development battery-electric 18 t LHD would be trialled at LKAB’s Sustainable Underground Mining (SUM) project in Sweden. Epiroc has already delivered a diesel-powered Scooptram ST18 to be trialled in autonomous mode at the SUM project.

It was Yameogo, a mining engineer with much experience operating in underground mines in Canada, that provided the event’s big picture talk in his presentation, ‘Will electrification spark the next wave of mining innovation?’

He talked up the need for industry collaboration between miners, OEMs and service providers in not only electrifying equipment and operations, but also other types of technology.

“That type of collaboration and co-creation framework will actually help mining companies also think about innovation and other items part of electrification and equipment, in general,” he said.

The focus narrowed slightly to open-pit electrification during Dr Bappa Banerjee’s talk, ‘An electric future for mine haulage’. Dr Banerjee, General Manager of Mining Equipment for Wabtec, emphasised from the off that there was no one-size fits all solution to going electric in this sector.

“It’s becoming clear to us…that perhaps it will be a combination of technologies that really help us get to a solution that is feasible,” he said.

This solution, he said, depended on the mine application and haulage scenario, underlining the need for technology flexibility.

In his presentation, Dr Banerjee pitted a diesel-powered haul truck with 2,500 horsepower (1,864 kW) as his baseline solution against a hybrid solution with a 2,500 hp diesel engine and 200 kWh battery as one alternative, and all-electric truck platforms equipped with trolley assist (with 800 kWh battery) and stationary charging (1,200 kWh battery).

The energy cost versus productivity outcome he showed proved his earlier point about different applications suiting different solutions, with varied results depending on if these trucks were deployed on downhill, uphill or flat hauls.

GE Transportation, since merged with Wabtec, has previously demonstrated a battery-diesel hybrid solution on a Komatsu 830E-1AC and Wabtec has plans to release trolley solutions for Komatsu 830E-5 and 930E-5 haul trucks in 2021, so this analysis includes hard industry data.

Dr Banerjee concluded on the decision-making aspect of going electric: “These are not just point in time decisions we have to make regarding the CAPEX and where we are in the lifecycle of the mine, but decisions across decades sometimes.

“Perhaps the best way to approach this would be to start with a technology that is more flexible up front or has more options.”

Brian Huff, Vice President of Technology for Artisan Vehicle Systems, a Sandvik Mining and Rock Technology business unit, used his presentation to reinforce that battery-powered solutions were the way forward in the underground environment.

‘Rethink the machine, not the mine’ was the title of his presentation and Huff stayed true to it from the off: “The basic message is that this is not as hard as you think it is. There is a real big change coming to the mining industry, but it may not be as difficult as you think to accomplish a conversion to battery-electric equipment.”

Similar to Hedqvist’s mention of the newfound freedom available to engineers when designing these next generation battery-electric machines, Huff explained that Artisan’s generation three BEV blueprint started with a battery-electric driveline and built from there.

“Major parts of the frame can be removed to facilitate swapping…[and you can have] double to triple the power density of the machine (compared with the diesel-powered equivalent) to improve performance,” he said.

He moved on to tackle the usual range anxiety question head on, displaying a video of a 13 km haul on a one-in-seven grade. Within this, he showed that the ability to swap batteries during the uphill haul meant there was no loss in haulage productivity when compared with the a similar payload diesel-powered machine.

The time losses related to battery swapping – around six minutes per swap with the Z50 – were more than offset by the increased haulage speed, according to Huff. “It is about 10% faster on the climb,” he said when comparing the BEV unit with a conventional diesel truck.

Productivity could be further boosted with the introduction of Artisan’s patented AutoConnect system. Fitted on the company and Sandvik’s newest 18 t payload LH518B LHD, this system allows the battery swap to be completed in well under five minutes, according to Huff. IM understands an AutoConnect retrofit option could allow the Z50 haul truck to match that swap time.

Add to this productivity benefit, decreases in operating cost and total cost of ownership, and it is hardly surprising Barrick recently signed off on a trial of four of these Z50s at its Turquoise Ridge joint venture gold mine in Nevada.

Safety, cost, maintenance, productivity and even battery life; you name it, The Electric Mine Virtual Conference discussed it.

The good news is a second dose of electrification talk is only four months away, with The Electric Mine 2021 conference taking place on March 15-16, 2021, in Stockholm, Sweden.

Sandvik and Barrick confirm Artisan Z50 trials at Turquoise Ridge gold mine

Sandvik and Barrick have confirmed the signing of a partnership agreement for trialing and enhancing battery-electric vehicles (BEVs) for underground hard-rock mining.

During a three-year production trial, Sandvik will deploy four Artisan Z50 BEV trucks at the Turquoise Ridge gold mine, part of the Nevada Gold Mines joint venture (JV), Sandvik said. Barrick is the operator of the JV, which is the single-largest gold-producing complex in the world, forecast to produce a total of 3.4-3.65 Moz of gold during 2020.

The announcement follows an acknowledgement of such a deal by President of Sandvik Mining and Rock Technology, Henrik Ager, earlier this month.

The Z50 haul truck, with a 50 t payload capacity, is a ground-up design that seamlessly integrates the most capable and proven battery electric powertrain available in the mining industry with the latest and most coveted features of any haul truck on the market today, according to Sandvik.

It is equipped with AutoSwap, a patented self-swapping system for the Artisan battery pack. This makes battery swapping faster and easier with a minimum amount of manual handling: changing the battery only takes about six minutes, and it can be done in a passing bay or old re-muck bay with no overhead cranes or external infrastructure needed.

In phase 1 trials, the Z50 truck already achieved more than 1,400 hours of production with over 1,400 loads, according to Sandvik. It reached production operation of up to 18 hours per day, with speeds of over 10 km/h observed on the ramp to the tip.

Some of the key performance indicators in the new partnership will include the performance of the BEV technology in a production environment, mechanical availability, average lifecycle cost and overall production cost, Sandvik said.

“We are always looking at ways to improve our performance, both in terms of sustainability and operational efficiency,”  Mark Bristow, Barrick’s President and CEO, said. “This partnership with Sandvik is exciting and will give us first-hand experience in BEV technology in our own production environment. It is a significant step to furthering our BEV strategy across the group.”

Ager added: “I am very pleased that Barrick and Sandvik have teamed up to perform these extensive trials in a daily production environment. It gives us the possibility to prove the performance of our BEV technology.

“The purely battery-powered truck helps to reduce heat and emissions underground, helping mines reach their sustainability targets and reduce ventilation costs. This raises the bar for what is possible and enables an all-new level of production and cost reduction for underground hard rock mines.”

A dedicated site project team will be jointly working with the Barrick operations team during the trial period to ensure that all data is captured and the experience from both Sandvik and Barrick is used to ensure the uptime and productivity targets are met, Sandvik said.

Bis looking at hybrid, electric and automated Rexx haul truck variants, Peate says

Bis is already offering clients a “step change in flexibility and efficiency” with its Rexx haul truck, but Chief Development Officer, Todd Peate, says the company has plans to offer hybrid, electric and automated versions of the 160 t payload vehicle as it looks to offer customers a further boost in productivity and their environmental footprint.

Speaking in a blog post on Bis’ website, Peate said the launch of Rexx, a solution that can come out of pit and travel up to 30 km while reducing fuel consumption up to 40%, is a fantastic example of a lower cost approach to running mining fleets.

Rexx was launched in 2018, with Peate saying six customers have been running detailed trials of this solution during 2019 and 2020 as part of fleet replenishment and cost optimisation project assessments.

Among these are trials at Gold Fields’ Granny Smith mine and Glencore’s Murrin Murrin operation, both in Western Australia.

“Rexx speaks directly to improvements in environmental footprint and productivity for our customers,” he said, adding that, in Bis’ short- to medium-term roadmap, variants will be available in both hybrid and electric forms, with the existing solution capable to be retrofitted with automation capability.

“With the success of Rexx and feedback from the market, we have a roadmap for a product family that will see Rexx continue to grow well into the back end of this decade and beyond,” he said.

Meanwhile, in other areas, Bis is developing a “category disruptor” in the underground market in the early part of 2021, Peate said.

He concluded with the news: “From an automation point of view, we’ll be bringing something to the market very soon in the form of an offering that has potential application for not only our equipment, but for all equipment in the industry.

“Stay tuned!”

Polymetal and SMT Scharf sign underground electric vehicle MoU

Polymetal and SMT Scharf have signed a Memorandum of Understanding (MoU) for a potential strategic cooperation in underground electric vehicles (EV) development in line with the miner’s climate strategy.

The MoU outlines that Polymetal and SMT will cooperate in the development, implementation and testing of zero-emission battery EVs. Initially, the collaboration is to be focused on mid-ranged LHDs and trucks, with potential involvement of drill rigs and utility vehicles in the future, Polymetal said.

IM understands Polymetal has previously tested RDH (now owned by Scharf under RDH-Scharf) battery-electric machines at some of its underground mines.

Two pairs of units (an LHD and truck) are going to be tested at Polymetal’s operations during the one-year trial with further collaborative re-design, signing of a distribution agreement and establishment of an after-sales support centre, Polymetal said, adding that the strategic cooperation is set to last for 10 years with an opportunity for further extension.

“The partnership with SMT grants us an easy access to customisable battery-electric vehicles which could positively contribute to our operating costs dynamics, greenhouse gas (GHG) emissions and personnel safety at underground mines,” Vitaly Savchenko, COO of Polymetal, said. “It fits well into our strategy to gradually involve EVs across the group’s operations and marks another step towards cutting carbon emissions by 5% in 2023.”

Polymetal’s GHG emissions from mining fleet and mobile machinery at the hubs with underground mines for 2019 were 334 Kt of CO2 equivalent, which is 12% of the group’s total emissions (Scope 1+ 2).

Epiroc to supply Vale with BaaS agreement, battery-electric equipment

Epiroc says the world’s first Batteries as a Service (BaaS) agreement has been finalised in Canada, with Vale and the mining OEM partnering on this new approach for utilising battery technology in mining operations.

Along with the BaaS agreement, Epiroc will be providing Vale with 10 battery-electric vehicles for two Canadian mine sites. These machines will include four Scooptram ST14 loaders, two Boomer M2C drill rigs, two Boltec MC bolting rigs and two Minetruck MT42 trucks. The miner will also acquire three of Epiroc’s charging cabinets and seven charging posts for equipment support, the company said.

Vale has previously said it hopes to have upward of 20 battery-powered vehicles operating within its North Atlantic operations (Creighton, Coleman, Copper Cliff, Garson and Thompson mines) by the end of 2020.

As mining companies continue to strive for sustainable productivity and zero emissions, the fast evolution and development of different options within the field of battery technology can be extremely challenging, Epiroc says.

With BaaS, Epiroc works directly with the customer to define a battery plan that suits the needs of their operation. The lifespan is guaranteed and the battery status is carefully monitored to ensure predictive maintenance with reduced downtime, according to the company. If a customer wants to increase or decrease their capacity, they can adjust their plan and the service will be tailored to meet their requirements.

As part of an ongoing sustainability commitment, Epiroc will remove old batteries from site and replace them with new batteries. These older batteries are then used for secondary applications and will be recycled at the end of the process, the company says.

The delivery of the battery equipment to both sites will occur over the course of 2020 and into the March quarter of 2021, according to Epiroc.

“A key component to the success of this offering is the flexibility it allows our customers,” Shawn Samuels, Product Manager Rocvolt, Epiroc Canada, said. “We take ownership of the battery itself and automatically replace and update the units as needed, which means the mine site can breathe easier and continue to focus on heightened production.”

Jason Smith, General Manager Epiroc Canada, said: “We value and look forward to continuing our successful partnership with Vale as we move towards a zero emissions future in mining together. We both recognise the positive impact a successful battery service implementation can have on operations, so our mutual confidence in one another is well placed.”

Sandvik gears up for battery-electric drilling revolution in southern Africa

Southern African mines will soon begin the transition from diesel-driven to battery-powered drill jumbos, with the introduction of the world’s first highly-automated underground electric drill rig by Sandvik Mining & Rock Technology, according to the mining OEM.

Saltiel Pule, Sandvik Mining & Rock Technology’s Business Line Manager for Underground drilling in southern Africa, says the Sandvik DD422iE rig has already seen enthusiastic take-up in mining countries with strict anti-pollution regulations such as Canada, with the innovation having been in development for the past three years.

“The key benefits of the battery concept in underground drill rigs are zero emissions and much less heat, making for safer and healthier working conditions,” Pule said. “There are many other advantages to this technology, however, including increased drilling productivity, reduced operating costs and better energy efficiency.”

One of the first mines to have received the DD422iE was the all-electric Borden mine in Ontario, Canada. Since then, Barrick has trialled a unit at its Hemlo underground mine, also in Ontario.

The Sandvik DD422iE’s electric driveline, with an electric motor mechanically connected to axles for high torque and high efficiency, allows the rig to tram independently between working areas. The unit’s high-precision inverter delivers exact control of the tramming speed, according to Sandvik.

“The rig only needs to be connected to mains power during the actual drilling, at which point the electric motor is connected onto hydraulic pumps,” Pule says.

Improved drilling power of up to 20% is achieved by an active power compensation system which draws reserve power from batteries during peak loads, according to Sandvik. Battery charging is carried out during those phases of the drilling cycle when power intake is low, such as during boom movements. There is, therefore, no waiting time to charge up batteries.

In pursuit of zero-harm safety standards, the unit uses sodium nickel chloride technology – regarded as one of the safest battery systems for underground conditions.

Sandvik also offers a battery rental option to customers, taking responsibility for battery inspection and maintenance, as well as responsible disposal at the end of battery’s life, the company says.

“The battery therefore becomes an operational cost for the mine, rather than a capital expense,” Pule says. “This option also gives the customer the certainty of predictable operating costs while adopting a new technology.”

In addition to zero emissions and less heat generation, the electric drill rig produces less noise, making communication easier and working conditions less stressful, Sandvik added. There is a reduced risk of fire, as there are no fuels exposed to hot surfaces – as can happen with diesel engines.

“The range of indirect savings that customers achieve when they move from diesel to electric includes lower ventilation costs underground, no need for diesel storage and diesel pipelines, and more control over operating costs,” Pule says.

MEDATech speeds up battery-electric mining charge

The potential for electric drivetrain specialist MEDATech Engineering Services to add another high-profile client to its list of mining company references is high given the developments the Collingwood-based company is currently working on.

Having helped Goldcorp (now Newmont) and several OEMs realise their vision of an all-electric mine at Borden, in Ontario, MEDATech is energising more electrification projects with its ALTDRIVE system.

The company has been developing electrification technology for heavy-duty, off-highway vehicles for about six years. Its current drive train technology, MEDATech says, is capable of being scaled for most heavy haul applications in mining and other industries.

These last six years have seen it help fellow Collingwood resident MacLean Engineering convert underground roof bolters, graders, water trucks and many other production support vehicles for Canada’s underground mining sector. MEDATech has also helped Torex Gold and its Chairman, Fred Stanford, develop the necessary equipment to take the Muckahi all-electric underground mining concept to testing phase. Similarly, it has played a role in Nouveau Monde Graphite’s all-electric open-pit mine vision as part of a Task Force Committee developing studies for the Matawinie project, in Quebec.

Aside from the Muckahi project, the ALTDRIVE system, having been engineered to replace internal combustion engines, has been the driving force behind this work, according to Jeff Taylor, Managing Director of MEDATech Engineering.

The powertrain consist of a hybrid, or completely electric means of propelling the machine with industrial batteries, and can be adapted to heavy equipment such as commercial trucks, tractors, excavators, buses, haul trucks, light rail and – most important in this context – mining vehicles.

ALTDRIVE leverages battery systems from Akasol and XALT, chargers and power electronics from Bel Power Solutions and Dana TM4’s electric motors. The balance of the power electronics, control systems and sub systems, thermo management systems, VMU (a software component critical to the power management of the battery, electric motor charging and regenerative capabilities), and integration engineering is developed by MEDATech.

Taylor says it is the battery chemistry and charging philosophy of the ALTDRIVE technology that differentiates it from others on the market.

“The battery chemistry is really quite advanced and is all based on the future of fast charging,” he told IM. “In this scenario, we don’t want the batteries to be brought down to a high depth of discharge (DOD). We instead want operators to carry out quick, opportunity charging on the go.”

Most of the machines the company has been involved in manufacturing to date have been equipped with 25-100 kW on-board chargers, yet Taylor thinks its new breed of fast-charge battery-electric solutions could eventually require up to 1 MW of power and be charged through an automated system.

Such powerful charging systems may be the future of MEDATech’s ALTDRIVE drivetrain technology, but for now it is focused on leveraging the system for the conversion of a diesel-powered Western Star 4900 XD truck (pictured).

Part of a collaborative project with a Western Star dealer in Quebec where the dealer (Tardif) has donated the truck and MEDATech has provided its materials and engineering expertise, the truck is equipped with a 100 kW capacity on-board charger, 310 kWh of battery capacity, loaded gross vehicle weight of 40,824 kg and 25% more horsepower than its diesel-powered equivalent.

Loaded, the truck can cover 85 km (0% grade) on a single charge (80% DOD). This vehicle is ideal as a pit master unit for short run material moving, road maintenance, water hauling/spraying and snow plowing activities, according to the company. The truck can be on-board charged (2.5 hours) and fast charged (1 hour) during idle periods (at 80% DOD).

The machine will be ready for demonstrations at a gravel pit around 15 km away from the company’s Collingwood headquarters in September, and it has already caught the attention of some major miners.

According to Taylor, Anglo American (Chile), Teck Resources (British Columbia) and Vale (Ontario) are scheduled to see the BEV 4900 XD unit in September at the Collingwood facility. “Each company is looking at an electric machine(s) for their operations,” he said. “They might end up with a different truck, built to their exact specifications, but they want to test this machine out to experience a battery-electric conversion.”

After the 24 t payload truck, the company has eyes on converting a 40 t payload Western Star 6900 XD diesel truck to battery-electric mode.

“This will just be a bigger conversion on a bigger truck,” Taylor explained. “We’ll have extra room on the truck for placing batteries and the extra motor that will be required. It will also be an all-wheel drive vehicle, as opposed to the real-wheel drive of the 4900 XD, which will need some extra engineering.”

While Taylor said work on converting this 40 t machine would not start until the all-electric 4900 XD had been tested, he saw plenty of opportunities for scaling up and down the ALTDRIVE technology to create more customised ‘green’ vehicles for the mining industry.

“If you look at any mine site in Canada, there are five or 10 vehicles you could replace with electric versions,” he said.

2BL to take ‘reuse + repurpose – recycle’ message to battery-electric vehicle market

2nd Battery Life Inc has appointed a new President and CEO that, it hopes, will position the company ahead of the curve on the downstream reuse of batteries for battery-electric vehicles (BEVs) in mining.

Vernon Cameron has been appointed to the top job, joining Chairman & Chief Technology Officer – and battery-electric vehicle specialist – Mike Mayhew on the executive team.

Cameron brings a wealth of experience in private equity, private and public companies with over 30 years of senior level experience on a global basis, according to the company. His hands-on experience in manufacturing environments, as well as global sourcing connections, will maximise profitability and drive enterprise value, it said.

Mayhew, who with Stacktronic is currently working on repurposing and electrifying a personnel carrier for use in the underground mining sector under the guise of his Mayhew Performance company, said he was “extremely excited” to launch 2nd Battery Life Inc to the market.

“The need for 2BL is critical for the future of battery electric as we implement more BEVs within the mining operations, as part of the overall equipment life cycle towards zero emissions.

“2BL will be the cornerstone of ‘reuse + repurpose – recycle” for mining clients on a global basis and we are going to create a Centre of Excellence to manage 2nd Battery Life.”

Cameron, who recently moved back to Sudbury, said: “The timing of entering this emerging market space positions 2BL to be ahead of the curve on downstream reuse of batteries for mining BEVs.”
