Sandvik reported it will launch its first Stage V underground loaders for hard rock applications. The base engine and selective catalytic reduction purifier are proven Volvo Penta technology, enhanced with a ceramic diesel particle filter.

The engine features passive regeneration of the diesel particulate filter and a modulating engine brake. With the former, soot is burned off the filter during normal operation. The latter enables the operator to adjust the engine braking power, allows better control of vehicle speed downhill, and minimizes brake and transmission overheating and brake wear, the company reported. The filter and engine brake contribute to equipment uptime, Sandvik reported.

The Stage V loaders are capable of operating with up to 3% reduced fuel consumption compared to the lower stages, the company reported.

Sandvik also released AutoMine Access API, which the company described as the industry’s first interoperability platform for autonomous underground loaders and trucks. The solution gives mines the ability to connect non-Sandvik equipment to Automine.

Sandvik reported the development as a step in its journey to drive a digital ecosystem that makes mining smarter, safer and more productive.

Separately, Sandvik announced a new transmission for its flagship TH663i (66 mt) and TH551i (55 mt) trucks. The new eight-gear transmission should enable the truck to up productivity with shorter cycle times, Sandvik reported. The previous transmission had six gears.

The hydraulic retarder operates simultaneously with the engine brake, enabling easier downhill control and higher speeds, the company reported. Further, lock-up to lock-up gear shifting enables quick and smooth shifting and keeps speed better while driving uphill.

The new size-class transmission is a result of extensive product development work to meet customer needs, the company reported.
