EARTHMOVING & EXCAVATION

CUTTING-EDGE POWER AND EFFICIENCY Durable new Generation 10 excavator withstands the toughest jobsites

T

he SK850LC-10 is the largest Kobelco Generation 10 excavator. The manufacturer says this machine features cutting-edge power and efficiency capabilities to make downtime a thing of the past. The SK850LC-10 is more durable than ever and able to withstand the rigours of the toughest jobsites. This Kobelco excavator delivers a dynamic bucket digging force of 90,598 pounds to achieve leading-class work volume. Premier working ranges and a powerful 146,800-pound drawbar pull force enable the SK850LC-10 to conquer rough terrain and slopes with increased productivity. This robust, 185,700-pound unit is powered by a 510-hp Tier 4 Final HINO engine, allowing it to tackle heavy-duty applications while remaining highly fuel efficient.

Impressive improvement in fuel economy

While operating in ECO-mode, the SK850LC-10 boasts an impressive improvement in fuel economy – approximately 17 percent compared to its predecessor. This boost in efficiency is a result of an enhanced hydraulic line layout that further reduces energy loss to ensure outstanding performance. A variable-geometry turbocharger also helps to lower fuel consumption, and a new selective catalytic reduction system decreases NOx emissions by 80 percent to provide low operation emissions. Operators can look forward to staying safe and comfortable in the SK850LC-10, regardless of the work at hand. An improved lever control force of 25 percent further lessens operator fatigue during long hours of operation, while added climate control outlets and an expanded cab interior provide a pleasant

work environment. A FOPS top guard, rear-view camera and swing flashers come standard on the SK850LC-10 to enhance jobsite safety. Maintenance on the SK850LC-10 is simple and cost effective. Easy access to maintenance data from the operation management system greatly improves ease of maintenance scheduling and ensures a long service life, while easy access to the cooling unit, engine compartment and electrical components ensure convenient day-to-day maintenance.

PROJECT MINOTAUR

A

mythical machine arose at CONEXPO 2017 with Case’s introduction of Project Minotaur. According to Case, Project Minotaur is the world’s first dozer–compact track loader hybrid. Since that unveiling the company has documented the journey of Project Minotaur in a series of videos. The machine features steel tracks and a new ripper design intended for severe ground conditions. Project Minotaur is currently in its second iteration. The CONEXPO prototype featured a radial lift pattern, but Case received feedback that a vertical lift pattern would be more desirable for this machine and made the change for the second version. Case says that the lift arm configuration wouldn’t make too much difference in dozing applications, but would add versatility to the machine for lifting materials into higher dump trucks. Another challenge in developing Project Minotaur is in ensuring that the stress of heavy dozing would transfer to the chassis, rather than just the loader arms, but the attachment still has to be quick and easy to switch out. A C-Frame designed to make switchout between dozer and CTL functions easy is patent-pending. There’s a lot of potential for this unique concept. “One guy saw it as a machine that could be lowered down a hole to help build a subway station,” said Brady Lewis, the project’s program manager. “Customers clearly got what it was, and we heard use cases we’d never thought of before.” Case has been doing field testing of Project Minotaur in Wichita, Kansas, and is providing updates of Project Minotaur at minotaur.casece.com.
