Mobile jaw crusher Powerscreen's new Premiertrak 300 jaw crusher is said to excel at higher fuel efficiency and lower transportation costs. The unit uses a 40-inch by 24-inch jaw chamber and is capable of producing up to 308 tons per hour of crushed material. Options include a vibrating grizzly feeder or a large fully independent hydraulically driven pre-screen. Both options are proportionally controlled by engine load to maintain optimal throughput. An optional hydraulically folding extended side conveyor, with a stockpile height of 10 feet, 2 inches, is available with the prescreen feature. A new bypass chute design incorporates a flap gate to allow operators to switch between using the side conveyor or sending material to the main belt without the need to fit a blanking mat on the bottom screen deck. A hydraulically adjustable closed-side setting can be adjusted in a matter of minutes without requiring tools, while the new hopper design incorporates a complete hydraulic fold-andlock system to eliminate the need for manual wedges. The crusher is powered by a 275-horsepower Tier 3-compliant Cat C9 ACERT engine or a 272-horsepower Tier 4 Final compliant Scania DC9 engine. Powerscreen | www.powerscreen.com Digital weight indicator Rice Lake Weighing Systems announces its newest weight indicator, the 880 Performance Series, a compact digital weight system and controller for mounting within larger control panels and DIN-rail applications. A smaller, removable indicator face and overall depth of just 4 inches make it one of the most compact full-size controllers on the market. The unit also adapts to a spectrum of technologies, whether they require USB, RS-232, or standard Ethernet connection. It can operate as a standalone controller, but also connects with a range of industrial networking protocols for PLCs. Rice Lake | www.ricelake.com Fuel efficient generator Atlas Copco introduces the QAC 1200 1MW generator, featuring a Cummins QST30G5 diesel engine that is Tier 2-certified and provides 1140 kVA/912 kW prime power rating. With a fuel efficient, electronically governed engine, the integrated fuel tank provides a minimum run time of eight hours. The unit was engineered with 500-hour service intervals to lower owning and operating costs. Low noise levels (85 dBA at 1 meter) make it suitable for sound-sensitive applications. An available option is a controller that allows a user to create a Power Management System. This allows a simple method to parallel two or more generators beyond 1MW. Atlas Copco | www.atlascopco.us Utility class loader Built from the ground up, Kawasaki's new 70Z7 uses the IntelliTech Operation System, which captures every aspect of working conditions and operating demands and adjusts the powertrain and hydraulics for the most efficient use. Unlike its larger-sized classmates, this unit's intelligence is automated to take guesswork out of the operator's hands. It has a high-intensity LCD monitor, straightforward dash arrangement, and intuitive systems, making it easy for operators of varying skill levels to run. The unit sports a 173-horsepower Cummins engine, a ZF five-speed transmission, work mode selector, 50-degree bucket tilt-back for carrying, and a full turn tipping load of 22,800 pounds.
