Since 2004 mining and tunnelling have been an increasingly important part of bauma, which is held in Munich every two years.
The mining and quarrying sectors at bauma this month (April 11-17) will feature numerous innovations and developments.
Equipment that will be of interest to delegates from New Zealand includes the new Certiq machine (wireless) monitoring system from Atlas Copco Rock Drills AB, which is now the standard for the company’s construction and mining machines.
This system not only tells users how a machine is being used (or was used), but also provides details of availability rates, maintenance requirements, and automatic performance reports via email.
Bell Equipment has complemented its E series generation of articulated dump trucks with four new models with higher nominal loading capacities. Bell has also made the step towards EU4/Tier4 final with new six cylinder engines from Mercedes-Benz optimised by MTU for off-road operations.
Visitors to the trade fair will find out about the latest product solutions in the area of inclined conveying, closed belt systems, heat-resistant conveyor belts, energy-optimised transport or lightweight PVC belts. Trackman rubber caterpillar tracks from Continental AG resemble closed drive belts with a tread profile on which heavy equipment and traction machines such as transporters or road building machines run.
Cummins will present the next generation of ultra-clean engines which meet the EU’s Stage V emissions regulations for construction machines and mining/materials handling equipment due to come into force in 2019. These engines, which produce anything from 55 to 300kW, not only satisfy the “virtually zero emissions” requirement of the regulations, but offer an increase in power and torque of up to 10 percent.
Another innovation is a slant directional drilling (SDD) rig. Slant directional drilling is an alternative drilling technique combining horizontal (HDD) and vertical directional drilling (VDD). While the entry angle with HDD is between eight and 18 degrees, it is 90 degrees with respect to the earth’s surface with VDD.
Keestrack will present its new H4 caterpillar mobile cone crusher (35 to 50 tonne transport weight). With a handling capacity of between 120 and 200 tonne per hour this proven cone crusher technology has been optimised specifically for mobile use. According to Keestrack, its innovative crusher control and monitoring solutions are “groundbreaking”.
Komatsu Mining will display its new 677 tonne PC7000, which it claims is “the safest and most efficient large hydraulic excavator in its class”. The PC7000 is powered by two 1250kW diesel engines and features a 36 cubic metre shovel or backhoe bucket, and has been tailored to the 240 to 290 tonne 830E and 860E dump trucks from Komatsu.
Liebherr will launch its PR 776 crawler tractor, the first infinitely variable hydrostatically powered crawler tractor in the 70-tonne category. Designed for the most demanding mining and quarrying applications, it is powered by a Liebherr 12-cylinder diesel engine with a maximum power of 565kW.
In the heavy-duty sector the “tipper versus dumper” discussion continues with models featuring a new rear tipper superstructure that improves performance of the heavy-duty tipper trucks. With a real volume of 28 cubic metres, these new tippers offer the same circulating capacities as dumper concepts and, depending on the routes involved, their turnaround speed is higher. They can use roads when empty or partially loaded, and a change of location can be achieved without any heavy or special transport measures.
As well as its range of trucks and engines, Scania CV AB will be showcasing its mining division at bauma. Transport accounts for more than a third of operational mining costs, and this manufacturer says it is aiming to bring about a positive change in its customers’ bottom line during tough times for mining.
The new 55-tonne capacity A60H from Volvo Construction Equipment meets a demand for articulated haulers with larger capacities. More than half of the articulated haulers sold globally by all manufacturers today are within the Volvo A40 size class. The Volvo A60H’s higher payload – 40 percent increase on Volvo’s A40 models – significantly lowers the cost-per-tonne ratio for hauler customers. The new size also offers a viable alternative to rigid dump trucks and construction trucks operating on soft, uneven or steep roads, allowing a similar amount of material to be hauled in a shorter cycle time. Using articulated haulers also reduces the level of maintenance required for haul roads on the jobsite, further improving profitability.
