Less than a year after announcing the introduction of the flame-proof LS312 underground loader, Sandvik Mining and Rock technology has dispatched its first South African unit to Sasol’s Sigma underground coal mine, near Sasolburg in Free State Province.

Sandvik said earlier this month that the first LS312 unit was signed off and ready for delivery, with IM later discovering the machine was destined for Sigma.

Earlier this year, Sandvik Mining and Rock Technologies’ Product Support Manager, Richard Hickson, said the first active units would start rolling off the local production line in the June quarter.

“The LS312 loader is an enhanced 12 t high-capacity heavy-duty utility vehicle, building on the best features of our 10 t LS190 and 12 t LS190S models,” Hickson said. “This raises the bar once more in terms of better performance, reduced emissions and lower total cost of ownership.”

Powered by the C7.1 mechanical engine, the new generation LS312 complies with Tier II emission standards while ensuring quieter and more efficient operation, according to Sandvik. The integrated exhaust after-treatment systems also reduce personnel exposure to harmful diesel emissions.

“Customers’ productivity will benefit from increased engine performance, with 20% higher torque and 8% more power,” Hickson said at the time. “The lower rpm at which the machine can run also translates into less engine wear and lower emission levels.”

Hickson highlighted that the new design continues to include a focus on reliability and maintenance, with the drivetrain enhanced with a 12 t axle, and the structural integrity of the front frame strengthened.

Maintenance crews will have easier access to hydraulic test points, which are now located in a panel on the side of the machine, making for safer working practices, Sandvik says. In addition, the improved cooling system will further reduce maintenance time.

The product also offers an optional electronic shutdown system, providing easier fault diagnosis and reducing the mean time to repair.

With the industry-driven need for the collection of machine and operational information, the Sandvik LS312 LHD offers an on-board data monitoring capability allowing for transfer of information via the mine’s Wi-Fi network and management through the My Sandvik Cloud platform.

“Safety is paramount in all our designs, and a proximity detection interface is now provided as standard,” Hickson says. “The lower frame design – facilitating improved visibility for the operator –has been retained in the LS312.”

Sandvik Mining and Rock Technologies’ new LS312 underground loader has found favour with South Africa coal miners, with orders already placed for the flameproof LHD.

The company announced it would be adding the LS312 to its line of coal load and haul vehicles back in November last year.

The first active units will start rolling off the local production line in the June quarter, according to Richard Hickson, Product Support Manager at Sandvik Mining and Rock Technologies.

“The LS312 loader is an enhanced 12 t high-capacity heavy-duty utility vehicle, building on the best features of our 10 t LS190 and 12 t LS190S models,” Hickson says. “This raises the bar once more in terms of better performance, reduced emissions and lower total cost of ownership.”

The local manufacture of this new model brings several benefits to customers and the economy, Stephan Greisiger, Production Manager at Sandvik’s manufacturing facility in Jet Park, South Africa, says.

“Local production of the LS312 units will significantly reduce the lead time to our market,” he said. “This makes it easier for customers to plan capital equipment purchases.”

Sandvik adds to underground coal loading and haulage line with LS312

Sandvik Mining and Rock Technology has launched the Sandvik LS312, a new 12-tonne capacity, heavy-duty flameproof underground LHD.

The LHD’s engine, a C7.1 mechanical engine with Tier II emission standard, has been developed into a new certified diesel engine system, which targets minimal emissions, maintenance and total cost of ownership, Sandvik says.

The LS312 is designed to meet the latest major international safety standards, including electronic diesel engine safety shutdown systems and roll-over and falling objects protection fitted as standard on all units. Significant improvements have also been made to operator cabin ergonomics and visibility to assist the safe and comfortable operation of the vehicles, the company said.

“This new LHD utility vehicle with Sandvik quick detachment system (QDS) provides a safe and efficient solution to meet the challenges of underground coal loading and hauling applications and reduces personnel exposure to harmful diesel emissions through use of Tier II engine and integrated exhaust aftertreatment systems,” Sandvik said. “Reduced consumables and up to 20% diesel fuel savings, as well as 15% reduction in service time due to improved maintainability, contribute to lower operating costs.”

Used in conjunction with Sandvik’s 57 t hydraulic assist roof support trailer, the LHD can help relocate larger longwall equipment, as well as a range of other QDS attachments, according to Sandvik.

Sandvik is also offering customers the possibility to upgrade and rebuild existing LS190 LHD fleets with the new C7.1 mechanical engine. Integration into other models, such as the LS170, is also planned in the near future, it said. This can be completed in conjunction with a rebuild or as a standalone upgrade package performed in one of its Sandvik OEM workshops.

Zane Swingler, Product Manager Flameproof Load and Haul, Mechanical Cutting Division, Sandvik Mining and Rock Technology, said: “Our new Sandvik LS312 flameproof underground loader is full of new innovations designed to improve safety, minimise emissions, increase productivity and lower your operating costs. We have combined feedback from customers and service personnel with our long history in underground coal LHDs to continually improve the product.”
