Tier 4 Final medium wheel loaders
Caterpillar introduces its new 980M and 982M wheel loaders. Equipped with Tier 4 Final ACERT engines, the units boast a combination of electronic, fuel, air, and after-treatment components. The 982M is a new all-purpose machine that will load on-highway trucks in two passes; however, design changes to the frames, linkage, horsepower, and powertrain extend its application to sand and gravel and earth bank excavation, as well as face loading in shot rock applications. It also has longer standard lift arms than the 980M, making it suitable for rail car loading. Like other M series loaders, powertrain updates have improved both performance and fuel efficiency. The hydraulic service center is virtually identical across the M series, with a consistent layout simplifying maintenance for service technicians. For operator ease, a switch has been added to the electronic service center to unlatch the door remotely, while the angle of the steps has been increased to 15 degrees, which enables operators to walk up as if they were using stairs. New roll-formed ROPS posts, larger convex mirrors, and integrated spot mirrors all improve safety. A new multipurpose touch screen simplifies operator interface with machine controls, rearview camera, and a fully integrated Cat Production Measurement system.

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 pre-screen 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-and-lock 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.

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.

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.

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.

Aluminum rollers
Aluminum conveyor rollers, from Horizon Conveyor Equipment, are said to offer robust strength at nearly half the weight of their standard steel counterparts. Designed using a 6-mm-thick aluminum tube, the rollers contain a steel shaft and sealed bearings, with the bearing housings manufactured from electrically conductive, glass-reinforced nylon. A large stationary integral stone guard forms the outer primary labyrinth seal, which prevents spillage buildup between the roller and the frame. Dust, debris, and smaller contaminants are kept out by a greased inner cupped lip seal, together with a sealed bearing.

More powerful artics
The new Cat C-Series articulated dump trucks, 725C, 730C, and 730C EJ ejector, feature new engines with more power, advanced transmission control, enhanced operator amenities, new serviceability features, and — for the 730C and 730C EJ models — automatic traction control. The design centers on customer requests for increased productivity, lower operating costs, superior availability, long-term durability, added rimpull/retarding capability, ease of operation, and high resale value. The 725C has a rated payload capacity of 26 tons and is powered by a Cat C9.3 ACERT engine rated at 314 horsepower. The 730C and 730C EJ are rated at 31 tons and are powered by a Cat 13 ACERT engine rated at 367 horsepower. All three models are available in Tier 2, Tier 3, or Tier 4 Final configurations. A diesel particulate filter and selective-catalytic-reduction system provide exhaust after treatment for Tier 4 Final models. Compared to prior models, the 725C has a 4-percent gain in gross power and a 20-percent boost in gross torque; the 730C and 730C EJ models have nearly 16 percent more power and more than a 30-percent gross torque improvement. To control speeds on downhill grades, 730C models employ a new engine-compression brake that provides 60 percent more retarding power than predecessor models. The 725C uses a fluid retarder with four operating modes.

Vocational truck
The all-new Kenworth T880 is designed for heavy-duty use, including hauling applications. It comes standard with a PACCAR MX-13 engine rated at up to 500 horsepower and 1,850 foot-pounds of torque. The engine provides lightweight, fuel-efficient power for vocational applications. The unit can be ordered with a 116.5-inch BBC hood optimized for the PACCAR engine or with the 122.5-inch BBC hood. The truck features a panoramic windshield for better visibility, quiet cab with triple-sealed doors, a five-piece Metton hood for easier and faster repairs, air-assisted hydraulic clutch, and lightweight, factory-installed lift axles.

Electric-driven air compressor
Doosan Portable Power’s new electric-driven VP900e portable air compressor operates between 400 and 900 cfm, without wasted energy. Replacing the typical diesel engine on the air compressor are three onboard electric motors that are controlled by a variable frequency drive system (VFD) — one air end motor and two cooling fan motors. The design creates operational efficiencies, using less power than is required of a typical, one-motor-fits-all design. The VFD monitors the needs of the compressor by changing performance of the motors to meet precise power requirements, preventing the use of unnecessary power. A low power start further enhances energy efficiency as it requires only a fraction of the power typically needed for motor start-up.
