Wacker Neuson has paired its popular 48-inch (eight-foot) ride-on trowel with a new electronic fuel injection (EFI) engine that offers added power, speed and fuel economy. The mechanical steer CRT48-37V and power steer model CRT48-37V-PS are both powered by a 37-hp Briggs and Stratton Vanguard air-cooled gasoline engine with the latest EFI technology. The engine features an automotive-style EFI system that delivers fuel more efficiently where and when it is needed, resulting in an easy starting, quicker throttle response, high blade speed capability, as well as improved fuel economy. Add this new engine to Wacker Neuson’s proven trowels designed for high productivity and operator comfort, and concrete contractors receive a winning combination to achieve high quality professionally finished slabs and floors.
Atlas Copco has introduced its PROi gas breaker with electronic fuel injection (EFI), an industry first that offers significant benefits for users needing to break concrete, cut asphalt, tamp soil or drive ground rods. The Cobra PROi provides as much as 10 percent more power than its predecessor, the PROe, at all working speeds, while optimal combustion reduces fuel consumption by as much as 10 percent. Operators can start the breaker in almost any climate or at any altitude.
Putzmeister America, Inc. has introduced its brand new Ergonic® 2.0 Control System at the World of Concrete. The completely new system, which will debut on the new 47Z-Meter Truck-Mounted Concrete Boom Pump, includes numerous design enhancements for improved operator experience and greater flexibility.
The modular four-track design of the the new TCM 180i permits working widths between 13 ft., 1 in. (4 m) and 59 ft., 1 in. (18 m), with hydraulic leg swing that allows for mobilizing into transport configuration in minutes
World of Concrete 2017 provided exhibitors with a hugely successful platform to start the year off strong, packing the show floor with qualified industry-related attendees, ready to make purchasing decisions on the latest equipment, products, and technologies available. Many exhibitors commented WOC 2017 was one of the best shows in recent memory, resulting in a 73% rebook on booth space for WOC 2018.
Wirtgen's latest slip form paver the SP 60i series replaces the SP 500 – and opens up new possibilities for contractors. Thanks to its versatility in inset and offset applications, the SP 60i series is the new multi-talent for concrete paving. With its SP 61i, SP 62i and SP 64i models, Wirtgen has developed a new generation of slipform pavers that combines the diverse applications of the globally successful SP 500, with the state-of-the-art technologies of the next larger SP 90i series.
Wirtgen will be showing several new machines for the first time in North America at the upcoming World of Concrete Trade Show. Wirtgen will be showcasing a slipform paver the SP 64i, one of three models of the new SP 60 series. Thanks to its versatility in inset and offset applications, the SP 60 series provides increased versatility in concrete paving. With its SP 60 series Wirtgen has developed a new generation of slipform pavers that combines the diverse applications of the globally successful SP 500 with the state-of-the-art technologies of the next larger SP 90 series.
Allen has announced the debut of their new HDX760 Riding Trowel. The HDX760 is a state-of-the-art, hydraulicallycontrolled ride-on power trowel that incorporates “Intelli-Power” to ensure peak performance, component safetyand extended life.
Roller-compacted concrete (RCC) got its start in the 1970s, when the Canadian logging industry switched to environmentally cleaner, land-based log-sorting methods. The industry needed a strong pavement to stand up to massive loads and specialized equipment, according to the Cement Association of Canada (CAC). Yet economy was equally important: log-sorting yards can span 40 acres (16 hectares) or more. RCC met this challenge and has since expanded to other heavy-duty applications.
ProAll Reimer Mixers operate on an entirely different principle than the typical concrete truck one might see on the road. Instead of mixing cement, aggregate and water at a batch plant, a Reimer Mixer delivers the constituents to the jobsite in separate bins and mixes them on the spot for a fresh mix anytime, anywhere. The technology offers several advantages, including the ability to deliver concrete over long distances to remote jobsites and the ability to control the composition of the concrete precisely as it’s delivered, including the addition of various other materials for special purposes, such as fibre, colour and many other chemical admixtures.
The new three-track Commander III Xtreme is unlike any other Commander ever built by GOMACO, and now has the ability to slipform a 24-inch (610-mm) radius. The new Extreme Package for multi-application pavers includes rotary-sensored slew drives for steering, sensored leg positioning, independent travel circuits to each track, radius software, GOMACO’s three-sensor radius system and repeatable mold offset.
The new S 38 SX from Schwing combines a tight (22’ 10”) front outrigger spread with a lightweight (Federal Bridge Legal) design and a five-section boom with more articulation than any other boom style. The new model is available in a three-axle configuration with cab-over truck or as a four-axle version with conventional truck to meet federal bridge laws. “This is a concrete pump that defines versatility for concrete contractors and pumpers,“ states Tom O’Malley, senior vice-president of sales and marketing for the manufacturer, “The new boom design hyper extends at every section to exceed the capabilities of Roll and Fold and Z Booms.” Key features of this one of a kind Roll and Fold boom are that all of the articulation is on the working side of the boom for faster deployment and it has the ability to snake the end hose deep into decks. The boom provides 106’11” of horizontal and 122’4” of vertical reach.
Production of up to 6 cubic yards per hour of cellular concrete on a continuous basis is now possible with the new Cretefoamer Model CS-6G which fits in a 3/4 ton pickup truck. It is designed to do jobs of 2 to 40 yards in less than a day. The cellular concrete can range from less than 30 pounds per cubic foot (pcf) up to 100 pcf or more.
The benefits to polyester concrete overlays for bridge decks and highways include shorter lane closures, increased live load capacities, higher tensile strength and a greater resistance to impact. The overlay can be placed as thin as ¾ inches and up to 12 inches thick in a single lift.
GOMACO introduced their new 3300 multiapplication slipform paver at Bauma 2016. It was specifically designed for right-side and left-side pour capabilities using a symmetrical design that makes it easy to pave from either side. Its U-shaped operator’s platform provides a complete view of the entire paving operation from anywhere on the platform and the control console easily slides from side-to-side to accommodate the direction of the pour.
Along the Appalachian Mountains from the Canadian–U.S. border to Tennessee runs Interstate 81 (I-81). Stretching for 1,376 km (855 miles), the route carries over 12 percent of the nation’s gross domestic product, and has subsequently been named the ‘trucker’s highway’. In recent years, hundreds of distribution warehouses have sprouted along this heavily trafficked corridor as Americans shift to online buying and demand shorter delivery times.
Designed as both a material transfer vehicle (MTV) and paver to significantly increase utilization rates, the rubber track Cedarapids CR662RM RoadMix from BOMAG features a new 260-hp (191-kW) Tier 4 Final Cummins diesel engine that delivers the power needed for high production applications. Boasting a low, 21-psi fully loaded ground contact pressure, the CR662RM can be used on all paving lifts, including the critical base layer, to virtually eliminate all forms of material and thermal segregation. Unlike MTVs with empty wheel loads in excess of 75 psi, the low-psi rubber track RoadMix machine does not cause rutting on the base layer, can cross bridges fully loaded and is transported to the jobsite like a 10-foot paver, so contractors can finish mainline and airport paving applications quickly, efficiently and with high mat quality.
