ROLLOUTS 12 AGGREGATES MANAGER / July 2016 Three new scraper tires round out size offerings The Goodyear Tire & Rubber Co. rolls out three scraper tires for construction and mining/earthmover applications, the Goodyear RT-3A (E-3), RT-3A+ (E-3+), and RL-3J (E-3). The RT-3A (E-3) and RT-3A+ (E-3+) are designed to offer enhanced traction in all underfoot conditions. They feature cool-running, radial construction; an aggressive tread pattern; a unique, geometric lug pattern for long tread life, even pressure distribution and enhanced mobility; buttressed, self-cleaning lugs to help protect against sidewall cutting; and more. The RT-3A (E-3) is available in size 33.25R29, while the RT-3A+ (E-3+) is available in size 40.5/75R39. The RL-3J (E-3) is for high-speed use on moderate-to-severe underfoot conditions. It features a zig-zag, centerline groove to offer superior lateral traction in high-torque ap- plications; tapered, self-cleaning shoulder lugs for excellent forward traction; a high-tensile steel belt package for enhanced impact resistance; and more. The RL-3J (E-3) is available in size 37.25R35. Goodyear Tire & Rubber Co. | www. goodyear.com New scrapers leverage automation for higher performance Caterpillar says its new 630K Series wheel trac- tor-scrapers — 631K and 637K — were designed to replace the 630G Series. The redesign includes an Advanced Cushion Hitch that uses new soft- ware to dampen end-of-stroke movement of the load cylinder for a smoother ride, hydraulic- system refinement that simplifies the bowl quick- drop function, and draft-arm-overflow guards that divert material away from the sides of the bowl. Plus, a new Auto-Stall system quickly brings the transmission to operating temperature for faster transitions from torque-converter drive. The open-bowl 631K and open-bowl twin-engine 637K offer a payload capacity of 34 cubic yards. The 637K features a Fuel Economy Mode that adjusts shift points and power distribution for optimum fuel economy. The 630K Series includes the following standard features: Engine over-speed protection, tire spin reduction, differential-lock-engagement protection, high-pressure steering, machine-speed limiter, ground-speed control, sequence assist, load assist, payload estimator, and Cat grade control. Caterpillar | www.cat.com Standalone plant can produce three products Terex Minerals Processing Systems says its new CRH1313R portable impactor and screen plant offers versatility to handle rock crushing, concrete recycling, and asphalt recycling. The highly mobile plant is said to be a complete stand-alone, closed-circuit unit capable of producing three products. It features a high-production Cedarapids IP1313 impactor with a 3- or 4-bar 50-inch rotor powered by a Tier 4, 450-horsepower diesel en- gine, direct drive to crusher, and 200-horsepower generator. A heavy-duty undercrusher pan feeder protects the conveyor belt from damage by absorbing the high-velocity discharge from the crusher. The 5-foot by 16-foot, patent-pending, dual-slope two-deck screen handles heavier loads for more capacity. Both screen deck products can be returned to the crusher for maximum production. A 48-inch by 16-foot high-stroke Cedarapids "Advantage" feeder with 60-inch grizzly bar or optional stepped-tine-style grizzly section feeds the impactor. The plant is said to be simple to operate, quick to set up, and easy to transport Terex Minerals Processing Systems | www.terexmps.com
