76 E&MJ • MAY 2019 EQUIPMENT GALLERY frame, Metso reported. A typical Metso Truck Body weighs up to 30% less than a traditional steel-lined truck body. De- pending on the application, this translates into a payload increase of several tons, the company reported. The body is available globally. Lining options ensure applica- tion-specifi c fi t, even in operations that struggle with problems such as carryback. New Version of Rig Control System Epiroc released the fi fth generation of Rig Control System (RCS 5) for Pit Viper blast- hole drill rigs. Complete with capabilities such as machine-to-machine communica- tion and real-time drill plan sharing, and functions such as Auto Tower Angle and Integrated Camera View, RCS 5 offers the new Drill Plan Generator function, which facilitates creating and editing drill plans on board the rig or from a remote location, the company reported. The Drilling Data Screen function features real-time depth and penetration rate feedback with histo- gram for easy in-hole monitoring. RCS 5 is the next evolutionary step toward fully autonomous mining, Epiroc reported. Cat to Build Electric LHD Caterpillar reported it would develop a lithium-ion battery-powered R1700 LHD that would feature onboard charging. The R1700 was introduced in 2018 as a new design and featured a fuel-saving electro- hydraulic system that provided increased loader forces for improved digging, the company reported. The battery-powered loader will leverage components from the Cat Microgrid solution. A proof-of-concept unit trialed prior to the releases of both the R1700 and Cat's MEC 500 fast-charging system reportedly exhibited more than a tenfold decrease in total energy costs, near- ly eight times less heat generated, signifi - cantly less noise, immediate torque avail- ability, reduced dust levels, and reduced tire wear. Additional expected benefi ts in- clude improved safety and production. Self-cleaning Tire for Loaders, Graders Bridgestone announced the launch of its Firestone VersaBuilt All Traction (AT) 14.00R24 radial tire line for loaders and graders. The tire is engineered to provide improved traction, versatility and depend- able performance, upping productivity, the company reported. The tire completes the VersaBuilt AT line, which is designed for improved traction with increased tire life. All models feature a heavy-duty all- steel casing and a SideArmor side- wall that defl ects stones and debris to protect against cuts and punc- tures. Addition- ally, a self-clean- ing tread pattern allows for more traction, the company reported. Other key features include a nondirectional pattern, a proprietary compound that increases longevity and durability, and an open shoulder design. Cat Cylinder Heads CGR Ghinassi previewed the new C11-C13 series, Caterpillar aftermarket cylinder heads for the range of C-series engines. The cylinder heads are produced in Ravenna, Italy, alongside models C9, C10, C15, C16 and C18. The company reported it is the only manufacturer of Caterpillar aftermarket cylinder heads supplying the complete range. Hauler Tire Creates Options Michelin North America introduced the MICHELIN XDR 3 surface-mine haul tire in size 27.00R49 for rigid dumpers with a 400-ton-payload capacity. The tire is designed with new compounds, corro- sion-isolating cables, and a revolutionary tread pattern that helps provide excep- tional tire life, the company reported. The design allows customers to choose between increased speed and load for the same tire life as predecessor competition or reduced speed and load for increased life. The tread pattern provides excellent load distribution across the contact patch,
