Liebherr-Canada has delivered a new 150-tonne-class R 9150 excavator to Hammerstone Infrastructure Materials, bringing the fleet of this model at Muskeg Quarry in Alberta to three units. All three R 9150s are deployed at Muskeg Quarry, one of Western Canada’s largest limestone operations supplying high-quality aggregates to the oil sands sector. The additional machine signals continued high-volume production requirements and reinforces demand for large-class hydraulic excavators in regional aggregate supply chains.

Metso has commissioned a 4 MW extra-large slurry pump test rig at its Test and Training Center in Sala, Sweden, expanding full‑scale product development and performance verification for high-capacity pumps. The facility, described as among the largest slurry pump test rigs globally, allows controlled testing of large-duty units under realistic flow, head and solids-loading conditions. For mine operators and designers, this should provide more reliable hydraulic data, improved wear-life validation and better sizing guidance for demanding mill discharge and tailings applications.

Epiroc has secured a large order from Sibanye-Stillwater to supply low-profile underground equipment for the Siphumelele shaft at the Rustenburg platinum operations in South Africa. The package includes low-profile loaders and utility vehicles tailored for the mine’s constrained stopes, where equipment height and manoeuvrability are critical for production and ground control. For engineers, the move signals continued investment in mechanised low-profile fleets in mature PGM orebodies, with implications for layout design, ground support access and maintenance planning in tight headings.
