Sandvik expanded its mobile crusher offerings with the launch of the UJ310+ jaw crusher and the UI310+ Prisec impact crusher. Designed specifically for the U.S. market, the UJ310+ offers an economic option for primary crushing. It features a CJ411 jaw crusher and a double-deck vibrating pre-screen. Assembled on a single trailer frame and mounted on a quad axle bogie, it is said to be easy to transport via a low loader and quick to set up. The UI310+ offers an impact version on the quad axle bogie. It features the patented CI512 Prisec impactor and has a double-deck vibrating pre-screen.

McLanahan Corp. introduced the MMS Track Trommel, a mobile unit that can be containerized when nearly fully assembled. The manufacturer says the trommel can be set up and running within 15 minutes. Capable of handling up to 165 tons per hour of material, it features a self-cleaning drum to minimize downtime. The drum — which measures 16 feet, 9 inches, by 4 feet, 7 inches — features four lifter bars and three wrap-around screen mesh sections. All mesh sections are bolted to the outside for quick media changeouts. The trommel has variable speed drives on all conveyors and can be hydraulically driven with forward and reverse capabilities.

Kleemann highlighted its new, intuitive crushing control system, Spective, at ConExpo-Con/Agg. From the beginning of operation, the operator is supported by a touch-panel screen, which provides a step-by-step guide through the startup process. On the start screen, the operator sees a diagram of the entire plant with its adjustable functions. The operator selects a function and is guided through all necessary steps. If a fault occurs during machine operation, a fault diagnosis is shown on the display, and downtimes may be reduced. Similar to a phone app, the system is designed to intuitively walk the operator through the control system for reduced errors and more efficient operations.

Caterpillar highlighted its 745 articulated truck, which offers a 45.2-ton rated payload capacity and a completely new cab that was re-engineered from the inside out to improve comfort and ease of operation. The external ‘spinal’ rollover protection system (ROPS) features bonded rear quarter glass that eliminates the structural pillar for a dramatic improvement in visibility. A new ‘wake up’ feature initiates machine displays as soon as the door is opened, while the improved door seals guard against dust and lower the sound levels inside the cab by 5 decibels. Infrared glass reduces solar heating, while left and right sliding windows increase ventilation and improve communication. A new combined transmission and hoist lever give operators single-lever control over truck speed and body hoisting functions to minimize operator effort and automate repetitive operations.

McCloskey Washing Systems introduced Sandstorm, a modular wash plant that includes feeding, screening, and washing, along with stockpiling of products on a single compact chassis. The range, including the 516, 620, and 824, can process feeds up to 550 tons per hour, with up to four grades of aggregate and two grades of classified sand. Easy access around the plant allows for simple operation and safe maintenance. The S-Line range combines the modular plant with sand screws as another option for sand producers.

John Deere added the 844K Series-III and 844K Series-III Aggregate Handler to its loader lineup. The new wheel loaders feature a 13.5-liter John Deere PowerTech Tier 4 Final diesel engine (380 horsepower for the standard unit, 401 horsepower for the aggregate handler). They are equipped with standard five-speed transmission with torque-converter lockup in gears two through five. This feature increases acceleration, speeds, and cycles, and optimizes power and fuel efficiency during transport, roading, and ramp climbing, the manufacturer says. The Aggregate Handler is built for two-pass loading with increased power, large tilt cylinders, higher hydraulic pressure, and increased counterweighing to handle bigger material-handling buckets (9.3 cubic yards/9.8 cubic yards). It is said to cut loading time by 30 percent with reduced fuel consumption by eliminating the third pass.

Astec Mobile Screens introduced its latest patent-pending hybrid technology featured on its GT205 Mobile Multi-Frequency Screen at ConExpo-Con/Agg. The hybrid multi-frequency screen can run on either line power or diesel power. It features a 5-foot by 20-foot screen. With its multi-frequency technology, the manufacturer says operators can expect up to 50 percent higher screening capacity on the bottom deck. The unit offers on-site flexibility and simple controls.

Atlas Copco rolled out the PowerROCT45-12 LF drill rig. The unit, with telescoping boom, is said to drill precise holes ranging in diameter from 3 to 5 inches. A 20-foot lead rod plus a three-rod, carousel-style rod handling system gives the operator an on-board depth capability to 54 feet with single pass capability of 18 feet. The basic rig configuration comes equipped with RD 22S hydraulic rock drill and 370 cfm air compressor. A Power Eco feature saves on fuel consumption by allowing the operator to select one of three engine speeds – 2,000 rpm, 2,100 rpm, or 2,200 rpm. Fuel economy varies by mineral type and deposit conditions, but in soft rock, 10 percent or greater reductions in fuel consumption have been typical, Atlas Copco says.

Metso featured its MX crusher, which is based on patented multi-action crushing technology that combines the piston and rotating bowl in a single crusher. It is said to cut operational costs by 10 percent and enable 10 percent higher uptime than traditional cone crushers. Key benefits include an easy under-load setting adjustment and wear compensation without having to stop the crusher. The cavity design, stroke direction, and distributed crushing action enhance rock-on-rock crushing for extended maintenance intervals. The manufacturer says the crusher can use up to 70 percent of the mass of new wear parts.

Haver & Boecker introduced a skid-mounted Hydro-Clean 1000 Wash Plant. The washing system includes both the Hydro-Clean 1000 washing system and the Tyler L-Class vibrating rinse screen. By mounting both pieces on a custom skid structure, the system is semi-portable and can be constructed more quickly than a custom system without the costs of custom engineering.

KCMA Corp., a subsidiary of Hitachi Construction Machinery Group, rolled out the 957Z wheel loader. Equipped with a six-cylinder, 16-liter Isuzu diesel engine, the loader does not need a diesel particulate filter to meet Tier 4 Final requirements. Improvements in the standard lock-up torque converter speed cycles and improve fuel efficiency. Systems respond more quickly to vehicle demands to improve power and speed, while a new joystick steering option opens up the operator area for increased visibility and comfort. An XT package can also be equipped to handle 12-ton payloads, which allow for two pass loading on 24-ton dump trucks.

Dig Assist, the latest in a suite of programs offered for the Volvo Co-Pilot interface, provides real-time guidance for operators. Using the in-cab interface with a 10-inch, high-resolution touch screen, excavator operators can input job specifications and track progress along the way. The operator opens the application and inputs a target depth and grade before beginning work. Then, the operator can visualize the bucket and machine’s position in real time, with indicator guidelines that provide a reference point for digging. An onscreen light bar display notifies the operator when the desired depth has been reached.
