With its kinematics and hydraulic power, the new R 956 crawler excavator, from Liebherr, is designed with increased breakout and digging forces for tough operating conditions. The unit weighs in at 117,945 to 123,020 pounds, depending on configuration, and is powered by a 322-horsepower, Tier 4 interim engine. An automatic idling system helps to optimize fuel consumption, along with two-stage turbocharging with intercooler, which increases power at low revs. A “Regeneration Plus” function allows for accelerated lowering of the boom without sacrificing power.

McClanahan Corp. spent the last two years engineering a new jaw crusher designed for high-performance primary crushing. Safety lock pins and hydraulic assist for wear parts change-out makes maintenance safer. Adjustments to the closed-side settings are now simpler. Hydraulic rams are isolated from crushing action, allowing longer life and full automation, while nearly eliminating toggle migration. The attack angle and crushing stroke pattern were re-engineered to increase capacity by up to 15 percent, while minimizing wear on the jaw dies.

Cat’s new 990K wheel loader offers more power and increased payload for improved productivity and fuel efficiency. It features a redesigned cab that delivers a sleek operator interface and quiet environment, as well as several features to promote operator and maintenance technician safety and performance. Designed as a loading tool for the 773, 775, and 777 trucks, it has a rated payload of 17.5 tons, up from its 16.5-ton predecessor, the 990H. New Performance Series Buckets promote fast filling and full buckets; they are available in sizes ranging from 11.25 to 13 cubic yards. The Cat C27 ACERT engine powers the unit and delivers an 11-percent increase in power compared to the earlier model. New power of 699 horsepower helps increase production without a corresponding spike in fuel consumption. Additional fuel-saving features include ECO Mode (on-demand throttle), engine-idle shutdown system, and engine-idle kickdown/auto-resume mode.

Nesco’s DustPro Series H spray system is designed for hydraulically driven track-mounted plants. It includes a high-pressure pump with hydraulic motor, control panel, and wireless remote. The pump module features two output lines, each with a solenoid valve. One line supplies nozzles at the feed hopper to control dust when the plant is charged, the other supplies nozzles at strategic locations throughout the rest of the plant. Spray nozzles at the hopper also can be automated by installing an optional presence detector. Wireless remote operation allows the loader operator to control the spray system by using spray nozzles only when and where they are needed.

Flexco’s Pneumatic Single Rivet Driver is now compatible with its BR Rivet Solid Plate fasteners and installation tools. When used in conjunction with the fasteners, it speeds installation by up to 33 percent. The driver features a dual handle for balance and ergonomic gripping, a heavy-duty rod for high-quality splices, and pneumatic driving power for robust installation. A single trigger pull per rivet saves time and reduces worker fatigue.

Kleemann’s new Mobirex MR 110 ZSi EVO 2 and MR 130 Zi EVO 2 represent the next evolution of its contractor line with enhancements focused on economy and operational safety. Crusher inlet openings of 43.3 inches (MR 110 ZSi EVO 2) and 51 inches (MR 130 Zi EVO 2) provide feed capacities of up to 350 or 450 tons per hour, respectively. The ‘S’ unit includes a secondary vibrating screen with extra-large screening surface mounted on the discharge conveyor. The screen can produce spec material and potentially eliminate the need for a separate screen. The feeding unit has hydraulically folding hopper walls and locking system, which speeds setup. A vibrating double-deck prescreen between the hopper and crusher eliminates fines from the product flow before they enter the crusher, reducing wear and fuel costs. Both units are Tier 4 Final compliant and use direct drive crushers and electric drives for the vibrating conveyors, belts, and prescreen.

Paladin Attachments introduces the new JRB roll-out bucket for wheel loaders. The bucket is said to improve the dumping height of any loader, making it easier to clear 13-foot, 6-inch haul trailers, while increasing the productivity of single-side filling operations. It uses twin, dual-cushioned cylinders to top the bucket to its edge, increasing the working dump height of the bucket. Available in sizes that range from 4- to 7- cubic-yard capacities in half-yard increments, the roll-out bucket is available in either quick-coupler or pin-on attachment styles and includes the jumper hoses.
