Fixed dragline 8750

BUCKET CAPABILITY 76-116 m3 (100-152 yd3) BOOM LENGTH 109.7-132.5 m (360-435 ft) WORKING WEIGHT - APPROXIMATE 5.8-7.5 million kg (13.1-15.9 million lb) Offering the highest levels of overburden removal productivity at the lowest total cost per tonne (ton), the 8750 is the flagship model of the Cat dragline product line. The first dragline of any kind to be successfully equipped with AC IGBT drive systems, we developed this superior technology for the sole purpose of making your workday more productive, predictable, and most importantly, safe. AC ELECTRICS TRIED AND TRUE AC IGBT ELECTRIC DRIVE SYSTEM, NOW ON MINING EQUIPMENT'S LARGEST PLATFORM You will experience greater machine uptime, lower operating costs, and faster cycle times with our AC dragline designs that leverage institutional knowledge built on 30 years of experience commissioning more than 200 AC equipped machines worldwide. BENEFITS OVER DC MACHINES Superior availability – Routinely demonstrated electrical availabilities of greater than 95%. – Extended mean time between failures, and reduced mean time to repair. Better reliability – Less vulnerable to input voltage variation. – No filters, robust design, independent of mine network. – Full power available with voltage ±10%. – Continues to operate with reduced power with voltage –10% to –30%. Greater efficiency – Provide up to 10% energy savings over the life of the dragline. – AC drives have an overall efficiency of 92% vs. DC machines of 88%.
