Sandvik upgrades Toro TH320, TH330 underground mining trucks

Sandvik has upgraded its Toro TH320 20-t and Toro TH330 (pictured) 30-t trucks to, it says, reduce customers’ costs of ownership and improve productivity.

With a hardy structure, compact size and fit-for-purpose components, the trucks are built to be robust and reliable and tailored to meet productivity targets in challenging underground environments, according to the company.

Both upgraded trucks come with a 235 kW Tier 3 Volvo Penta engine with catalytic purifier and muffler, delivering long engine lifetime in underground mining conditions. The 8 litre engine has a  high-tech injection system that contributes to an efficient combustion and low fuel consumption, Sandvik says. Furthermore, it is calibrated for use in high-altitude conditions without sacrificing performance or reliability.

The heavy-duty and efficient aluminium cooler has “outstanding” corrosion resistance and is easy to clean, helping to reduce total cost of ownership, Sandvik says. To minimise brake and transmission overheating and brake wear as well as to provide better control of downhill speed, the trucks can be equipped with an optional engine brake.

Sandvik has equipped the trucks with new heavy-duty axles using limited slip differential to maintain traction, which are expected to have an extended lifetime compared with the previous models.

“We have really worked to improve availability and reliability and reduce the time needed for servicing or maintenance,” Pia Sundberg, Product Line Manager, Trucks, at Sandvik Mining and Rock Solutions, says. “For fast ramp speeds when hauling ore, we have equipped these trucks with a new transmission with automatic gear shifting and torque converter lock-up.”

To increase uptime, Sandvik has also made upgrades to enable easy and fast maintenance. The trucks are designed for daily ground-level maintenance. When accessing the top of the equipment is required, the entirely new access system on the front of the truck provides a steady grip, including three-point contact high-contrast handles and anti-slip steps. The proven hydraulic system of the truck is simple and reliable, contributing to ease of maintenance and lower total cost of ownership.

Sandvik bolsters Toro LHD line up with LH515i

Sandvik Mining and Rock Solutions says it is launching a new, higher-capacity 15-t size class loader as a next generation model for the current 14-t Sandvik LH514.

The 15-t Toro™ LH515i has one tonne greater capacity than its predecessor, yet it is designed to operate within the same footprint. This new member of the Toro family has been redesigned from the ground up, leveraging all of the benefits of its predecessor, while improving the design based on customer feedback, according to the company.

The new loader has been designed following the principles of intelligence and simplicity, Sandvik says. The Toro LH515i features a totally new Sandvik intelligent control system with 12-in touchscreen colour display, making loader health monitoring easy, providing quick access to data and enabling new solutions for efficient troubleshooting, the company says.

“With a multitude of smart technologies and optimised for use with Sandvik’s AutoMine® and OptiMine® systems, Toro LH515i brings digitalisation to the operator’s fingertips, enabling optimal productivity,” Sandvik says. “To ensure quick and efficient maintenance, the loader features easy access to service points, roomy component layout organised to facilitate servicing and excellent access to systems, both in the cabin and on top of the equipment.”

The loader features an entirely new cabin designed to provide an ergonomic working environment for operators during long shifts, including increased leg space, new seat and dashboard and improved visibility over the extremely flat rear frame of the loader.

The Toro LH515i is available with two different engine configurations from Volvo Penta: the 265 kW Stage V diesel engine, and the 256 kW Tier III engine.

Equipped with selective catalytic reduction exhaust gas technology and a new diesel particulate filter, the Stage V configuration meets very stringent emission regulations. To further help to reduce their greenhouse gas footprint, both versions of engines are fully compatible with paraffinic diesel fuels meeting the EN 15940 standard, Sandvik says.

The launch of the new loader is part of Sandvik celebrating the 50-year journey of Toro loaders and trucks.

New GHH 45 t capacity dump truck about to enter underground market

GHH has developed a new 42 t payload dump truck that, it says, offers maximum drive power, improved turning radius, steep dumping angle and excellent ergonomics and safety.

The German manufacturer of heavy machinery for civil engineering, tunnelling and mining, which has roots that go back to 1758, has three other underground dump trucks in its underground mining portfolio (in addition to two within its low profile dump truck offering and one within its flameproof portfolio) spanning 15-35 t payload applications. The new truck is the largest in its portfolio.

The new MK-42 offers an up to 45 t payload, 19-24 m³ dump body capacity, maximum drive power, a great turning radius, improved dumping angle and excellent ergonomics and safety, according to the company. It has a streamlined, innovative product design, which just received the Red Dot Design Award, GHH added.

The 460 kW Mercedes OM473 forms the engine base, fulfilling the latest EU Stage V emission standards. GHH also offers Tier 3 and 4 versions for less regulated markets, while an alternative Volvo Penta TAD1651 or 1671 engine option is available.

The vehicle rests on Kessler axles with oscillating articulation and front axle suspension, while the power is transmitted by a converter and gearbox combination from the Dana 8000 series.

Designed for use in harsh environments, especially in underground hard-rock mining applications, the MK-42’s dimensions are surprisingly compact at 3,062 x 10,535 x 2,719 mm (WxLxH). A steep dumping angle of 68° leads to high efficiency productivity and improved cycle time, according to GHH.

The company said special emphasis was placed on a safe and simple design, with low maintenance and repair costs, and operator safety and comfort kept in mind through the entire design process. The ROPS/FOPS certified cab is ergonomically designed to be spacious, quiet, pressurised and effectively air-conditioned to ensure maximum operator comfort while minimising fatigue, GHH says. The strategically placed trainer seat, meanwhile, provides for effective operator training.

The new MK-42 fits seamlessly into the manufacturer’s range of dump trucks and is the perfect haulage partner for GHH’s LF-14 loader, with the combination of the two offering three pass loading, GHH said. Extensive consulting, aftermarket support, parts sales and technical training are just a few of the services GHH offers to all customers worldwide.

Global sales will start shortly as the prototype truck enters its final stage of rigorous testing, GHH said, which added that a special version, the MK-A45, will be marketed exclusively for the Russia market.

Sandvik and Volvo Penta collaborate on Stage V underground LHDs

Sandvik says it is readying the release of its first Stage V compliant underground loaders for hard-rock mining applications following extensive testing.

In early 2020, the company’s newest intelligent loaders, the Sandvik LH517i and Sandvik LH621i, will get the Stage V treatment. The Stage V Volvo Penta engines will be globally available as options, but require ultra-low sulphur fuel and low-ash engine oil to operate, Sandvik said.

The planned release follows more than 10,000 hours of LHD testing underground, on multiple customer sites in Europe, and with millions of hours of on-highway experience from Volvo. This has led to the new technology meeting customer expectations, equipment performance requirements and the most stringent emission regulations valid at the moment, according to Sandvik.

The base engine and selective catalytic reduction (SCR) purifier are proven Volvo technology, enhanced now with a ceramic diesel particle filter (DPF), according to Sandvik.

“As a result of the collaborative product development work, the engine – delivered by Volvo Penta – and Sandvik load and haul equipment work seamlessly together to maintain productivity and reliability in the most challenging environments,” Sandvik said.

The benefits of Stage V compliant loaders include reduced amounts of particles in the diesel exhaust – helping mines to improve air quality underground – and the ability to operate with up to 3% reduced fuel consumption, compared with previous stage engines.

Sandvik said: “Another key enabler for the equipment availability is passive regeneration of the diesel particulate filter; the soot accumulated in the filter is burned off during equipment normal operation, without the need for frequent stand still regeneration.”

A new feature in the Stage V engine is the modulating engine brake, which enables the operator to adjust the engine braking power, allowing for better control of vehicle speed downhill, while minimising brake and transmission overheating and brake wear. Both the modulating engine brake and the passive regeneration contribute to high uptime of the equipment.

Added benefits of the Stage V engines include high altitude operating capability – up to plus-3,500 m above sea level – and lower noise levels compared with previous Stage engines.
