MINING TRUCKS hold its own when it comes to hauling on grade and getting out of the sticky underfoot conditions sometimes present at these mines. This is also backed up by the fact two MT6300 ACs previously operated in the Canadian oil sands. Liebherr lines up latest technologies Trolley assist seems to be growing in popularity and not only in the ultraclass. Austrian iron ore miner VA Erzberg intends to electrify the main haul road of its Erzberg mine site and operate a fleet of T 236 trucks from 2021 under trolley assist. Liebherr is not new to trolley having eight T 284 trucks now under trolley at FQM’s Sentinel copper mine in Zambia and with its large T 284 fleet at Cobre Panama set to operate under trolley in the coming years. But this deal is significant involving the much smaller 100 t T 236. This electrification project would increase Erzberg life of mine significantly and reduce CO 2 emission on site. The statement added: “Liebherr is proud to participate and support this outstanding initiative of VA Erzberg.” Representatives of VA Erzberg and Liebherr celebrated this new collaboration at the Liebherr booth at Bauma 2019 in Munich. At Cobre Panama, trolley-assisted haulage is a concept that is being adopted during the early life of operations. The primary truck haulage fleet is being delivered “trolley-assist ready” (TA). Additional pit ramp width has been included in the detailed pit phase designs to allow for the physical placement of transformers and catenary wire poles. In places, these ramps could be extended onto the waste dumps. At the end of 2018, two Komatsu Mining P&H 4100XPC rope shovels and 16 Liebherr T 284 trucks were operating in the Botija Pit. An additional two 4100XPC rope shovels, three ultraclass Komatsu L-2350 wheel loaders and 14 further Liebherr T 284 ultraclass trucks will be progressively commissioned during 2019. In total, a fleet of up to 45 Liebherr T 284s, five Komatsu P&H 4100XPCs has been allowed for. Back to Liebherr’s main offering, and the manufacturing hub Liebherr Mining Equipment Newport News Co says it strives for continuous improvement to its product line of mining trucks and excavators. Safety, productivity, and performance are at the core of these new features. “Liebherr has been designing, developing, and servicing high-quality mining trucks for over 20 years. The Liebherr production factory in Newport News, VA works to continuously improve the efficiency and availability of their mining equipment. This goal- oriented approach is why customers and operators around the world prefer Liebherr.” Investing in the latest product upgrade for the T 264 mining truck results in a higher payload capacity of 240 t/265 tons. To maintain 30 International Mining | MAY 2019 performance and increase productivity, the T 264 offers multiple engine options with power ratings up to 2,013 kW/2,700 HP. “This allows customers to move more materials in less time, while supporting the additional weight of the increased payload. The new front wheel design and upgraded braking system offer quicker reaction times to increase safety for operators, particularly when travelling downhill. The upgraded wheel motors and rear gear ratio boosts torque and acceleration to provide similar cycle times with 10% increased payload. This truck is best matched with the Liebherr R 996 B (four passes) and Liebherr R 9800 (three passes) mining excavators.” Existing T 282 C and T 284 mining trucks can be retrofitted for increased payload and production capacity. Now capable of hauling additional payload to reach a total capacity of 375 t/413 tons, “this improvement will allow for maximisation of productivity, with the added benefit of enhanced compatibility with Liebherr’s R 9800 mining excavators in a five pass match.” “Constantly striving for improvement, Liebherr provides customers with a choice of engine options. Tier 4 solutions are designed to reduce emissions and satisfy global requirements (established by the EPA for all new mining and construction equipment). This practical consideration is an example of Liebherr’s commitments to customer satisfaction and environmental sustainability. Tier 4 Final is already available on the T 264 and the T 284.” Finally, the new Liebherr Mining Data (LMD) online portal offers real-time insights and data regarding performance and availability of mining trucks. This OEM solution software offers a single dashboard for improved fleet management of Liebherr Mining Trucks, so that customers can track KPIs and generate custom reports. “LMD now comes standard with all new Liebherr ultra- class mining trucks, and the hardware kit is available as a retrofit for the T 282 C generation mining trucks. Providing end-to-end solutions for machine data monitoring and analysis is one of many ways Liebherr continues to improve and add value for all customers. A few benefits of LMD include detailed application analysis and optimisation, increased safety, reliability, and machine uptime, with reduced maintenance, repair time, and cost through actionable insights.” The ultimate in flexibility: BAS Mining Trucks It is nice once in a while to divert the focus away from large rigid mining trucks; after all many surface mines worldwide employ tipper trucks for haulage, particularly for long hauls and in remote regions where if the cost and service support network for large rigids can be avoided then it offers a potential solution. One of the most innovative players in this area is BAS Mining Trucks based in The Netherlands, and part of EXA Holding, an umbrella company comprising a variety of independent companies. BAS says it can offer in its range, which is customised for mining but modelled on the Volvo FMX or FH16 trucks, solutions for mine haulage distances from 2 km up to 250 km between the mine and the processing plant. There are a lot of modifications made to suit the mining application, including a different battery box and altered fuel tank location, Powertronic gearbox, reinforced hydraulic suspension axle mounting, beefed up new component frame with special mounting brackets and completely customised tipper. Single mounted Goodyear 650/50R24 tyres allow the trucks to handle a lot of challenging underfoot conditions. The models include the five axle BAS 10x4 Tipper with up to 55 t payload, the five axle 10x6 Tipper/Pusher with up to 55 t payload and the six axle 12x6 Tipper with 75 t payload. There is also a 10x4 Pusher for ejecting ore which is suitable for both surface and underground mines. BAS Mining Trucks recently delivered two new FMX540 10x6 pusher trucks to the Gala Mibrag lignite mine in Germany. They are achieving a 50% higher productivity and 25% less fuel consumption than competitor trucks, hauling sticky clay up to 1.5 km one way
