Product News DRX Impact Beds offer maximum belt protection FLEXCO exhibited the newly-upgraded DRX (Dual Relief Xtra) Impact Beds at Mining Indonesia 2011. Designed to deliver maximum protection to conveyor belts in the load zone, DRX impact beds are carefully engineered to maximize belt protection, offering unprecedented ease of installation and maintenance. Recent upgrades to the DRX200, DRX750, and DRX1500 impact beds have further improved installation and serviceability. The Slide- Out Service feature on the DRX allows direct access to the bars and bolts for easy inspection and quick, safe maintenance when required. Flexco’s BCP product manager Ryan Grevenstuk says, “Reducing the number of bolts and improving their accessibility enhanced an already highly serviceable product.” While other beds rely solely on the support bars to reduce impact, DRX impact beds incorporate Velocity Reduction Technology in the Upgrades to Flexco’s DRX Impact Beds have improved installation and serviceability. structure design. This multi-level support effectively deadens impact energy and reduces reaction forces for less rebound and material digestion. The impact bar supports have a unique inverted design that acts as a first level of impact defence, while channel crossbeams transfer impact energy to the isolation mounts. These isolation mounts provide additional force reduction, absorbing energy and minimizing transmission back to the belt. Angled impact bars help centre material on the belt and anti-migration tabs prevent them from moving with the belt if bolts loosen. Also among the Flexco innovations at Mining Indonesia was the new PT Smart Belt Trainer. This was developed to further enhance the Flexco line of belt tracking products, joining the Belt Positioner and the heavy-duty PT Max Belt Trainer as an option for ‘medium-duty’ tensioned belts. Flexco says the economical and versatile PT Smart works with both mechanical and vulcanized belts, is made of durable materials and is easy-to-install. The PT Smart Belt Trainer adopts the same characteristics of the PT Max, including the patented Flexco ‘pivot and tilt’ design. With this technology, Flexco says the PT Smart applies greater belt tracking discipline than conventional pivot-only belt-steering devices, correcting even the most stubborn tracking problems on medium-tension belts. A fully-enclosed, stainless steel pivot bearing is found downstream from the roller, creating an almost immediate tracking result. The bearing requires no lubrication and is guaranteed not to seize. Cummins QSK95 extends mining power capability CUMMINS has extended its mining power capability with the new QSK95 engine which will provide a 4000hp (2983kW) capability for ultra-class mine haul trucks. Cummins says this represents the highest ever power output introduced by the company for severe duty-cycle operation. The 95 litre displacement QSK95 is purpose-designed to provide enhanced strength for 360 ton and 400 ton (327 and 363 tonne) payload class trucks, with the capability to increase truck speeds for climbing steep gradient haul roads and boost hauling productivity with reduced operating cycle times. The QSK95 will be available as a global mining engine platform capable of operating at mine sites anywhere in the world and meeting all emissions standards, including Tier 4 Final in North America by using Cummins Selective Catalytic Reduction (SCR) after-treatment. Cummins says the 16 cylinder QSK95 reaches the mining power output previously available only from 20 cylinder engines. High power density is achieved with a hardened power cylinder featuring the strongest single piece forged steel piston available in the industry. Deep structural strength is provided by an all new ductile iron skirted block. This increased strength contributes to higher engine uptime availability, extended life-to-overhaul and more cost effective rebuilds. Cummins Mining Business executive director Jason Rawlings says, “The QSK95 is designed to meet the highest expectations in the mining industry for uptime availability, reliability and durability that will exceed all other previous engines intended for ultra-class haul trucks. “This combination of deep inherent strength and proven systems means that the QSK95 will be ready to provide outstanding performance on the mine site from Day One. The QSK95 will fully complement the success of the QSK60 and QSK78 engines in ultra-class haul truck applications. These engines offer the widest and most flexible power choice in the industry.” The 4000hp (2983kW) output of the QSK95 engine is well within its design capabilities, with potential power increases available in the future to provide the possibility for the next generation of ultra-class haul trucks to move beyond 400 ton (363 tonne) payload capacity. Cummins says the stronger engine design of the QSK95 means more reliability in-service and less to rebuild at engine overhaul, considerably reducing total life cycle costs. 70 | ASIA Miner | January/February 2012
