Axera Range of Mining Jumbos Aims to Set New Performance Standards

Bringing new levels of performance to the working environment in underground mining applications has resulted in improvements to Tamrock's Axera range of mining jumbos. The company is announcing one new model and upgrades to its product offering. A desire to place an increased emphasis on improving the work environment has been the inspiration for improvements to the Axera range of mining jumbos from Sandvik Tamrock. The company has focused on three models in its range with the aim of offering customers higher standards with regards to operation and servicing for these machines. Axera 7 is the new high performance twin boom jumbo that replaces the D07. "This product will lift the bar, in terms of performance, in its size class for mining jumbo," says Mr. Jaakko Koppinen of Sandvik Tamrock Corp, Underground Division. He adds, "With the introduction of Axera 7, the focus is on maintainability, serviceability, safety and ergonomics." The jumbo can be used typically for applications where the heading size ranges from 4x4m to 6x6m. The Axera 7 is equipped with the new Tamrock HLX5-series hydraulic rock drill that has a percussion power rating of 20 to 22 kW. It can drill from 43 to 64 mm (1 11/16-2 1/2 inch) blast holes and can also drill cross-cuts and bolt holes. It can work with drifter rods up to 4,6 m (16 ft) in length. The unit comes equipped with two 55 kW electro-hydraulic power packs as well as having an articulated carrier with hydrodynamic transmission. In addition, the company is announcing upgrades to D05 and D06 models in the form of the new Axera 5 and 6.
