New Graders Built to Bear Down
It’s difficult to argue when Volvo Construction Equipment says that “what really matters” for grader productivity is blade down pressure and blade pull force. Well, with emphasis on overall machine balance and distribution of the main grader components, the new G900B-Series motor graders have the highest blade down pressure in each weight class, the company claims. Using larger-displacement engines with cooled exhaust gas recirculation (EGR) technology to meet Tier 4 Interim emissions requirements, each of the G930B, G940B, G960B and all-wheel-drive G946B grader models can be driven by either the Volvo HTE840 transmission with eight forward and four reverse gears (standard) or the HTE1160 with 11 forward and six reverse gears. These transmissions boast three and eight power curves, respectively, matching power output to the traction available, and each uses the “shuttle shift” system to move between forward and reverse without the operator needing to stop the machine or use the inching pedal. The four Volvo graders range from 34,520 to 38,709 pounds in operating weight.
Large Excavator E-ases Into Clean Emissions
Its arrival has been anticipated, having been first announced in late 2010, but the 349E’s formal North American release this summer still opens a new chapter in the Caterpillar large-size excavator heritage. Replacing the 345D L, the 349E adopts updated nomenclature to more closely reflect the actual metric tonnage of the machine. Operating on either ultra-low-sulfur diesel fuel exclusively or a blend with 20-percent biodiesel, the 396-net-horsepower C13 engine uses Cat’s Clean Emissions Module (CEM) to meet Tier 4 Interim emissions standards. In automatic mode, the CEM regeneration system allows the 349E to work as normal with no interruption to the work cycle, automatically sensing when to regenerate both during idle and when the machine is working. The manual model allows the operator to override the automatic setting if desired. Fuel-saving features introduced on the 349E include one-touch idle control, isochronous speed control, economy power mode and an engine idle setting that allows selection of how long the excavator can idle before it shuts down.

Originally a single field tracking and analysis solution, it has been expanded to include three modules: Field (field tracking and analysis), Logistics (resource planning and dispatching) and Maintenance (equipment maintenance and repair management), the latter to be released next year. Each module can be purchased as a stand-alone system, or together as an integrated suite.
Blue World Crete
Portland cement alternative
Scientists at Blue World Crete discovered Geo-Blue Crete II, a geo-polymer binding agent for cement that serves as a complete low-carbon footprint alternative to Portland cement. It looks like, acts like, works like Portland cement, and can be distributed in the same way with the same equipment but with less-expensive manufacturing costs, according to Blue World Crete. It is a one-part system that requires a simple paddle mixing of its powdered chemical formula at ambient temperatures. No heat is required in its manufacturing process. It is water-retardant, acid-retardant, discourages the oxidation of rebar, and has a near-zero coefficient of expansion.

Three herbicide options for land managers
DuPont Perspective, Streamline and Viewpoint herbicides are based on aminocyclopyrachlor, a new proprietary active ingredient from the manufacturer. The herbicides provide long-lasting activity on a wide spectrum of difficult brush and broadleaf weeds in utility rights-of-way, roadsides, railroads, nature preserves, parks and other areas. Low-use rates and dry-blended formulations mean these new herbicides require less handling, tank-mixing, storage space and waste disposal. DuPont Perspective herbicide selectively controls broadleaf and invasive weeds, including thistles, leafy spurge and knapweeds, along roadsides and other sites, while preserving desirable grasses and natural habitats. It also helps control ALS- and glyphosate-tolerant species, including kochia, marestail and pigweeds. DuPont Streamline herbicide controls brush in industrial rights-of-way where desirable native and perennial grasses need to be maintained. It controls tough species, including boxelder, hackberry and mesquite. DuPont Viewpoint herbicide provides broad-spectrum brush control of tough species, including boxelder, hackberry, mesquite, oaks and sweetgum in utility and industrial rights-of-way.

The Neway system also provides predictable roll stiffness for high center of gravity loads – particularly important for front- and rear-discharge mixers. The second suspension – the 40,000-pound TufTrac All Wheel Drive (AWD) high-performance vocational suspension – is also available as an option for the Western Star 4800 with 40,000-pound axles. Specifically designed for on- and off-road high-articulation operations, the 40,000-pound TufTrac mounting is a lighter, more-affordable alternative than the 46,000-pound option.
Vehicle-based laser mapping has options
StreetMapper Bridges, a vehicle-based laser mapping system from Allpoint Systems, is now being offered with a range of tools for the automatic calculation of bridge heights and other measurements. Designed to simplify the task of processing the billions of individual laser-scanned measurements recorded by the mapping system, StreetMapper Bridges is ideally suited for road construction and maintenance projects and abnormal route calculations. The mapping system automates processing of 3D-laser-scanned measurements using complex statistical algorithms to identify road surfaces, isolate bridge data, identify lane markings and remove noise such as highway traffic. The application then extracts cross-sections from the data and calculates clearances and other user-defined measurements. This automation enables large-scale use of laser mapping by eliminating manual inefficiencies and reducing the chance for error.
