Volvo ADTs, excavators hit the ground running at Weda Bay nickel project

At the Weda Bay nickel project in Central Halmahera, Indonesia, a fleet of Volvo articulated haulers and excavators are, the mining OEM says, offering excellent stability on soft ground for safety-conscious mining service contractor Samudera Mulia Abadi, while also delivering high uptime, productivity and fuel efficiency.

Samudera Mulia Abadi, headquartered in Manado, North Sulawesi, is one of Indonesia’s leading service contractors for the mining of gold and other minerals. The privately-owned company specialises in mine preparation – including infrastructure and site establishment, earthwork and land clearing, and project management – as well as excavation, loading and hauling in open-pit mines, and on- and off-road haulage.

The company’s latest endeavour is a five-year contract on a $30 billion project to extract nickel ore and transport it to the smelter at the Weda Bay nickel project in Central Halmahera. The main challenge here is the soft terrain in the pit and on the hauling roads.

“We try to remain efficient in carrying out any work in order to achieve the best return and there is no compromise on safety,” Willson Sastroamijoyo, Commissioner PT Samudera Mulia Abadi, says. “Every line of work must prioritise safety. Given the pit and hauling conditions, Volvo articulated haulers are the perfect choice as our production unit. Volvo excavators are also suitable to handle ore material like this.”

When the project began in August 2020, Samudera Mulia Abadi commissioned a fleet of 17 Volvo articulated haulers (six A40G and 11 A60H models) and 12 Volvo crawler excavators (two EC200D, five EC210D, two EC300DL and three EC480DL models), which will remain on site for as long as possible.

On delivery, dealer Indotruck Utama provided training to Samudera Mulia Abadi’s staff to promote safe operation and help them get the most value out of the machines. Since then, the dealer has continued to carry out refresher training as operator behaviour and safety procedure on site play an important part in increasing safety in eastern Indonesia.

The A60H is the largest Volvo articulated hauler with a 33.6 cu.m body volume and 55,000 kg payload capacity, while the A40G is the third largest, offering a 24 cu.m body volume and 39,000 kg payload capacity. On both models, the matched drivetrain, automatic drive combinations including 100% differential locks, all-terrain bogie, hydro-mechanical steering and active suspension ensure excellent traction and operator comfort on the most difficult terrain.

They are also designed for extreme durability and high fuel efficiency so that operators can reliably move more tonnes per hour at a lower cost, according to Volvo. The Hill Assist, Dump Support System and Rear View Camera, meanwhile, help to minimise the safety risk on site.

The Volvo crawler excavators, ranging from 20 t to 50 t in capacity, likewise offer excellent stability, fast cycle times and low fuel consumption, promoting safe, productive and profitable operation, Volvo said

“Our operators are happy to work with Volvo machines because they are comfortable and user-friendly. The quality, durability and comfort of the products have benefited us in many ways,” Sastroamijoyo says.

Volvo CE says: “Samudera Mulia Abadi works the machines hard – typically up to 22 h/d across two shifts, seven days a week – so machine availability is closely linked with productivity and profitability. It is crucial that they are durable enough to withstand such high utilisation and have simple service and maintenance requirements fulfilled by a responsive and reliable dealer. By always being ready to work, the machines help Samudera Mulia Abadi achieve its tonnes per hour and cost per tonne production targets.”

Because of this, the company has also relied on machinery from Volvo Construction Equipment on several other of its contracts over the last five years, including the Gag Island nickel project in West Papua and the Toka Tindung gold mine project in North Sulawesi.

At these two sites, Samudera Mulia Abadi operates a total of 116 Volvo machines, including 50 A40Fs, 17 A40Gs, five A45Gs and three A60H articulated haulers; one EC200D, eight EC210Bs, five EC210Ds, 12 EC350DLs, six EC480DLs, six EC950ELs crawler excavators; and one SD110 compactor.

“The overall machine performance is good and physical availability is above the target,” Sastroamijoyo says. “Of course, we are aware that the machines experience some occasional downtime, even if they are the toughest. The important thing is our how the dealer responds when these unfortunate situations occur.

“We have a good working relationship with our dealer Indotruck Utama. Their skilled service team speeds up the servicing time, while the consigned parts on site ensure high parts availability. Overall, the performance of the machines and the quality of product support increase our profitability.”

Terex Trucks to launch EU Stage V TA300, TA400 ADTs at Hillhead Digital

Terex Trucks is readying the launch of new EU Stage V versions of its TA300 and TA400 articulated haulers for the fast-approaching Hillhead Digital event.

The machines have been updated with an EU Stage V emission-compliant engine – and now deliver an improvement in fuel efficiency, an even stronger performance, as well as low total cost of ownership, the company says.

Both haulers come with a reduction of up to 7% in fuel consumption when compared with the Stage IV engine, according to Terex Trucks. Customers in Europe will also benefit from the haulers’ strong engine performance and excellent responsive power in all conditions.

Equipped with a Variable Geometry Turbo, the new Stage V engine allows for faster response at all engine speeds and an efficient combustion performance, according to the company. This helps improve operators’ efficiency while keeping the total cost of ownership low.

The TA300 and TA400 Stage V engine’s effective aftertreatment system uses selective catalytic reduction technology, removing the need for exhaust gas recirculation. This way, no exhaust gas is returned to the combustion chamber of the engine, helping to improve efficiency and durability of the machine. The diesel oxidation catalyst and a large-capacity diesel particulate filer ensure the engine meets the latest EU emission standards.

Kenny Price, Regional Sales Manager for EMEA at Terex Trucks, said: “Introducing the Stage V compliant engine for the TA300 and TA400 is part of our focus on delivering efficient, productive, high-quality and durable articulated haulers, while keeping the total cost of ownership down.

“We’re excited about presenting the new Stage V haulers to customers at Hillhead Digital.”

Just like the Terex Trucks Stage IV haulers, the new Stage V TA300 and TA400 are equipped with Scania DC9 and DC13 engines. Thanks to a drivetrain that is matched with the engine, the trucks deliver a powerful performance and excel in demanding work environments. For heightened levels of operational safety and control, an engine exhaust brake is installed as standard, which also reduces brake component wear.

The haulers also come with three-stage aspirated air filtration, which provides increased engine protection to lengthen maintenance intervals. All of this helps deliver strong, durable engine performance and keeps the total cost of ownership low.

The new Stage V TA300 and TA400 engines are also linked to Terex Trucks’ Haul Track telematics system, which allows customers to have visibility and control of the haulers, according to the company. They can access machine GPS location and tracking together with a range of downloadable daily performance reports such as machine hours worked, engine speed, idle time and system fault code alerts. This helps customers to plan maintenance more efficiently, maximises uptime and prolongs component lifecycles.

The first Stage V 28-t-payload TA300 and 38-t-payload TA400 are already rolling off the production line and will be delivered to the first customers in Europe from March, according to Terex Trucks.

Terex Trucks will present its new EU Stage V emission-compliant TA300 and TA400 dump trucks at the Hillhead Digital 2021 exhibition from March 30-31.

South32 adds Cat AD63 to Cannington underground trucking fleet

Last month, Cat dealer Hastings Deering sent out the world’s first AD63 truck to South32’s Cannington silver-lead mine in Queensland, Australia.

With a 63 t payload, the AD63 is the largest underground truck in the Cat product line, and comes with best in class speed on grade, according to Hastings Deering.

Joe Russell, South32 Cannington Vice President Operations, told IM that since taking delivery of the articulated truck from Caterpillar, via Hastings Deering, the company had started work on tailoring the vehicle to the mine’s specific requirements.

“Once the truck enters full operation, it will replace an older vehicle in our fleet,” Russell said. “The AD63 will be used in conjunction with the rest of the underground trucking fleet to move material to various locations within the South32 Cannington mine site.”

Russell highlighted the vehicle’s Euro Stage V Cat C27 diesel engine when reflecting on the recent fleet addition.

“The AD63’s engine specifications will help us to further reduce emissions, resulting in good outcomes for the environment and underground air quality,” he said.

Released in April, the AD63 features a 5% increased payload and more torque for enhanced production capabilities compared with its predecessor, the AD60, Cat says.

Additional new features enhance operator ergonomics, maintenance access and safety, and data collection for machine health monitoring, according to the OEM.

South32’s Cannington underground mine produces about 3 Mt/y of ore.

Bell B60E truck bridges the RDT, ADT divide

Bell Equipment says it is continuing to push new boundaries in the mining industry with its 60 t crossover concept, the B60E 4×4, having an impressive balance between off-road performance, productivity, and fuel economy.

Designed to provide a crossover of both rigid dump trucks (RDTs) and traditional ADTs, the B60E has a single rear axle instead of the more typical double axle while retaining the traditional ADT characteristics of all-wheel drive, and articulation steering with an oscillation joint, Bell says.

According to Bell Equipment Product Manager: ADTs, Nick Kyriacos, this gives the B60E far better capabilities in challenging conditions compared with RDTs.

“The oscillation joint keeps all the wheels in contact with the ground allowing for consistent all-wheel drive performance,” he said. “If an RDT fleet owner is looking for more flexibility or is forced to stop production due to unfavourable conditions, then the B60E is a great solution for them. The truck has operated side-by-side with rigid dump trucks on several sites where it has proven it capabilities. Additionally, customers running a mixed RDT and B60E fleet are able to standardise on one loading tool whilst retaining a high level of flexibility when deploying their equipment.”

In comparison with traditional ADTs, Kyriacos explains that there are customers who do not need the level of off-road ability that their three-axle ADT counterparts provide.

“In these cases, the B60E offers a level of productivity never seen before,” he said. “There is negligible tyre scuffing on the 4X4 ADTs, which is a major wear point for the middle and rear axles of three-axle trucks.

“Some of our leading customers have experienced the B60E achieving more than double the tyre life of their 6×6 counterparts in the same application. The B60E’s tyre life also exceeded that of similar sized rigid dump trucks in the same application by 60% due to a combination of its all-wheel drive configuration, whilst the oscillation tube ensures that all wheels maintain even contact with the ground along the entire haul cycle.”

Kyriacos added that the company has sold a number of B60s to ADT customers in various parts of the world who are running them successfully and noting the increased productivity and tyre life.

Far larger than a conventional ADT bin, the B60E’s flat-bottomed 35 cu.m body resembles a rigid-truck bin in its dimensions and geometry, according to Bell. This makes it fully compatible with existing loading equipment in mines and quarries and assures a 2:1-heap of coarse blasted material, Bell says.

“The shape additionally allows the loading tool to easily place bucket loads evenly within the bin for efficient loading, which is not possible in comparable ADTs in this size class,” it said.

The truck has proven its versatility on customer sites moving rock, ore, and sand over extended haul distances, according to Bell, managing short, steep gradients, tight turning circles and poor underfoot conditions during inclement weather.

“To date, the average fuel consumption of all B60Es ever sold is less than 24 litres per hour,” Kyriacos said. “Carrying a 55,000 kg payload per cycle at that fuel economy, coupled with the extended tyre life, the B60E achieves the Bell design philosophy by continuing to deliver lowest cost per tonne solutions.”

In addition to cost efficiencies related to economies of scale and a highly economical drivetrain, the B60E is loaded with safety features incorporated into the truck as standard, including Hill Assist, Safe Tip, downhill braking control and automatic traction control.

Other standard features include auto-greasing systems, rear-view camera, on-board diagnostics, and Bell [email protected]® telematics with full production data reporting.
