44 www.coalage.com March 2019 product news Liebherr Increases Ultra-Class Payloads Safety, productivity and perfor- mance are at the core of continuous improvements Liebherr is imple- menting with its line of haul trucks. Liebherr has been designing, devel- oping, and servicing high-quality mining trucks for more than 20 years and its haul truck production facility in Newport News, Virginia, has im- proved the efficiency and availability of their mining equipment. Investing in the latest product upgrade for the T 264 mining truck resulted in a higher payload capacity of 240 metric tons (mt) or 265 tons. To maintain performance and increase productivity, the T 264 offers multiple engine options with power ratings up to 2,013 kilowatts (kW )/2,700 hp. This allows mine operators to move more materials in less time, while supporting the additional weight of the increased payload, Liebherr said. A new front wheel design and up- graded braking system offers quicker reaction times to increase safety for operators, particularly when travel- ing downhill. The upgraded wheel motors and rear gear ratio boosts torque and acceleration to provide similar cycle times with 10% in- creased payload. This truck is best matched with the Liebherr R 996 B (four passes) and Liebherr R 9800 (three passes) mining excavators. The T 282 C and T 284 haul trucks can be retrofitted for increased pay- load and production capacity. Now capable of hauling additional pay- load to reach a total capacity of 375 mt/413 tons, this improvement will allow for maximization of produc- tivity, with the added benefit of en- hanced compatibility with Liebherr's R 9800 mining excavators in a five- pass match. Liebherr provides customers with a choice of engine options. Tier 4 solu- tions are designed to reduce emis- sions and satisfy global requirements (established by the Environmental Protection Agency). This practical consideration is an example of Liebherr's commitments to customer satisfaction and environ- mental sustainability. Tier 4 final is already available on the T 264 and the T 284. The new Liebherr Mining Data (LMD) online portal offers real-time insights and data regarding perfor- mance and availability of mining trucks. This OEM solution software offers a single dashboard for im- proved fleet management of Lieb- herr Mining Trucks, so 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 avail- able as a retrofit for the T 282 C gen- eration mining trucks. Providing end- to-end solutions for machine data monitoring and analysis is one of the many ways Liebherr continues to im- prove and add value for all customers. A few benefits of LMD include de- tailed application analysis and opti- mization, increased safety, reliability, and machine uptime, with reduced maintenance, repair time, and cost through actionable insights. www.liebheer.com High-power Density Couplings Voith expanded its TurboBelt TPXL portfolio of fill-controlled couplings to include 500-kW, 800-kW and 1,250- kW versions, which combine hydro- dynamics with intelligent control technology to optimize performance. The integrated controller matches the output torque exactly to the startup parameters of the belt conveyor sys- tem, thus reducing wear and increas- ing service life.
