Blow gun blows away construction debris

The Coilhose Cannon extreme high volume blow gun was specifically developed forremoval of asphalt, stone, concrete, scrap metal, rock and any other large pieces of debris typically found around heavy-duty construction sites, road/railroad maintenance work areas, sewer excavations and bridge repair locations. The Cannon is a safe and more efficient alternative to the “black pipe and ball valve” method for blowing away large chunks of debris, the manufacturer says. The Occupational Safety and Health Administration (OSHA) specially-engineered safety nozzle delivers a concentrated force of air to a specific area so that the debris can be directed toward the collection area. A “power assist” trigger minimizes actuation force and further helps control debris removal and cleanup. Safety extensions that are 24 inches and 48 inches make it easy to reach areas typically hard to access.

Maximized visibility among improvements

Roadtec’s 700-horsepower soil stabilizer/reclaimer has undergone a transformation during the past year. Compared to the first 2007 prototype, the current SX-7 looks very different. The changes in the body of the machine are mostly related to maximizing visibility. Visibility can be tricky with any large construction machine, but the manufacturer has redesigned the front and rear body of the machine so that visibility is dramatically improved. The cab is optional and can slide right or left, past the frame of the machine. With the SX-7, water and emulsion are handled by one system. Any single nozzle or set of nozzles in the spray bar can be turned off individually to precisely control how much liquid material is put down. The new Roadnet central control and diagnostic system provides operator feedback on virtually every function of the machine. Additionally, troubleshooting screens for all systems can be accessed with the touch of a button. With its variable volume cutter, the drum can be moved up or down in the housing on the fly. To create more mixing space, the drum down is moved down. If sizing of the material is critical, the drum can be moved up closer to the housing for the desired result.

The compact trencher is designed with more weight on the digging chain, so it can put more product in the ground faster, and its trenching capacities of 48 inches deep and eight inches wide enable a contractor to install a wide variety of utilities and irrigation systems. The RT24’s chain speed also can be adjusted by substituting a 10-tooth sprocket for the standard 12-tooth. For added stability and traction, the RT24 can be equipped with heavy-duty tracks that “walk” or oscillate 12 degrees. A special trail wheel that supports the oscillating tracks helps reduce break-over and increase stability over uneven and rough terrain.

A new addition, the biggest in the series

The screed is electrically heated, eliminating the need to change propane bottles in the middle of a large project. Dual vibrators provide 2,500 vibrations per minute.

Roadtec highway class paver models are now available with an optional temperature-sensing bar. Developed by MOBA, the device measures the temperatures of the entire mat width in real time and records that data, along with the corresponding GPS coordinates. The paver operator is able to see the temperature information on a screen, and has the ability to control the paving process better by spotting potential problem spots and taking corrective action. The company offers 8- and 10-foot pavers in tire or rubber track versions.

Calder Brothers Corporation has announced the availability of thermostatic control, electric heat on the company’s high-end Silver-16 screed. The Mauldin 1750-C paver now offers two thermostatically-controlled heating options; propane or electric. By entering the “auto” mode at the start of the day, the screed is assured to be at the proper paving temperature when it is placed on the mat.

Terex Roadbuilding’s CR662RM RoadMix material transfer vehicle and paver features a variable-pitch in-hopper auger design that dramatically increases material throughput. Pitch spacing – transitioning from 10 inches in the front to 11 inches and then to 12 inches the rear – channels material to the rear of the machine for faster truck unloading. The auger can exceed 500 tons per hour and reblends 100 percent of the material to combat both material and thermal segregation.

The Vision Series of asphalt pavers from Vögele America included the 10-ft. tracked Vision 5200-2 with HR 500-1E screed, the 8-ft. tracked Vision 5100-2, 10-ft. wheeled Vision 5203-2, and 8-ft. wheeled Vision 5103-2.

Cummins will unveil four engines ready for EPA Tier 4 Interim. Included will be the debut of the company’s next generation 4-cylinder QSB3.3 and QSB4.5 engines for compact equipment. Also brand new will be the QSX11.9 and QSX15 heavy-duty engines. Cummins will display the power plants complete from air intake to exhaust.

The compact 3.3-liter and 4.5-liter QSB engines extend across the 75-hp to 160-hp (56 kW to 119 kW) power range, which Cummins says lets OEMs standardize its 4-cylinder installations with common Tier 4 Interim engine architecture. The engines feature a scaled-down EGR system, the company’s compact equipment exhaust after treatment system, a variable flow turbocharger and space saving air cleaners.

The 11.9-liter and 15-liter engines cover a broad 300-hp to 600-hp (224kW to 447 kW) power band and share the same technology for Tier 4 Interim such as the company’s new XPI common-rail fuel system. A variable geometry turbocharger is able to continuously vary airflow boost to match engine rpm and load demands and a new

air cleaner includes an integrated sensor for monitoring temperature and pressure to ensure optimum flow.

Hamm will show its new HD+ range of 10 models of tandem rollers. The HD+ 90 (operating weight approx. 9 metric tons) and HD+ 110 (operating weight approx. 11 metric tons) articulated tandem rollers offer broad visibility thanks to their compact design and unusually large new XXL cab with a vaulted glass roof. The operating console with its display is never out of sight. It is permanently attached to and moves with the seat.

The newly designed articulated joint allows a superior weight distribution in relation to comparable tandem rollers, says the company. This results in increased directional stability and improved compaction quality, especially on bends and roundabouts. The offset during crab steering has almost doubled compared with the previous models in the HD series. Hamm offers a high-frequency version for the US market, where compaction is carried out at significantly higher speeds. The 9-metric-ton roller is also available in 2 models with separate roller drums – one for vibration, one for oscillation. During dynamic compacting work, the operator can use the front and rear roller drums at the same time but at different frequencies.

LiuGong will show its 888III large wheel loader which will be launched into the U.S. market later this year. The company will also present four upgraded excavators including a 36 metric tons model headed for America and a 12-metric ton dirt roller which will also be available in North America. No American-bound asphalt pavers are planned for this year but its possible we’ll see small models in the U.S. next year along with rollers.

Bomag will present new vibratory plates and new trench compactors including articulated and radio controlled models, both U.S. available. For the first time the company will send out two version of the plates, one for professional use and a simplified version headed for the rental market which will be easier for untrained hands to transport and operate. Expect Bomag to follow up with some other similarly split lines. Also expect a new small asphalt roller to hit the American market next year.

A new design for its small diesel engines will be shown by Kubota demonstrating a strategy of increasing fuel-burning efficiency with a new four-valve system. One result of this process is that after-treatment equipment has less work to do and so takes up less space.

From Vermeer comes the AXIS. The AXIS GB812 guided boring system comes with a laser guided system for accuracy in the trenchless installation of 10- to 14-inch (25.4- to 35.6 centimeter) pipe for on-grade water and sewer projects. The pit-launched system can install up to 350 feet (106.7 meters) of both rigid constructed, as well as fusible and restrained joint product pipe. Spoil is removed from the cutter head via a vacuum excavation system, eliminating the need to manually handle it within the pit.

Terex will present 50 products including new wheel loaders and mobile excavators. The company says its new TL130 is the “Titan” of its four high-performance loaders, “which are fitted with cutting edge hydrostatic traction technology as well as extremely sensitive high-performance hydraulics.” The completely revamped TW110 mobile excavator, a machine the company calls its flagship in this category, has been given a “futuristic makeover,” Terex says.

The multi-purpose Hauler Chassis concept will be launched by Volvo Construction. While the load body is a traditional ‘attachment’ for articulated haulers, several other effective hauling solutions can now be easily developed. Using E-Series articulated tractors, with a standard or extended frame as a base, bodybuilders can create a wide range of off-highway specials, such as hook lift, container hauler, concrete mixer, construction tractor, pipe carrier, wood chipper or timber transporter.

Sending out a winter SOS

The new SOS liquid deicing product from EnviroTech Services allows the use of salt at temperatures not previously possible, according to the manufacturer. In addition, SOS was designed to reduce leaching in stockpiles, specifically in warm, high humidity situations such as salt treated in late summer and stockpiled until winter. The deicer can be applied to a stockpile in advance or as it is being delivered, since treating the entire stockpile prior to application eliminates the need for pre-wetting saddle tanks. It also increases the speed and effectiveness of salt, and penetration into ice and snow pack, and prevents the stockpile from freezing or “clumping.”

Visibility for safety

American Safety Vest’s new high-visibility fluorescent orange field markers can be used for a variety of applications, including construction zones. The markers are 11 inches long, weather-resistant and visible from a distance. They are attached to sturdy, slightly flexible 6-foot, fiberglass poles that can be easily inserted into and removed from mud, dirt, gravel or sand. The markers come in sets of four.

Rips asphalt like a ‘SHARC’

Leading Edge Attachments, Inc. now offers the 23 Series “Multi-Ripper Tooth” (MRT) designed for excavators and backhoes. Conventional twin tiger teeth have two points that help to rip rock; however, they are side by side so that when they come into contact with rock. The force is shared by the two points of MRT and are positioned using “SHARC” technology (“SHanks on an ARC”) that places the points at staggered positions along an arc that has a center approximately near the bucket/stick pivot point. This allows the tooth to rip out a relatively flat bottom while focusing the entire excavator breakout on one point at a time.

The patented Wet Blade system from Diamond Mowers is a combination mower that allows for the selective application of growth regulators, her­bicides and other water-based chemi­cals to vegetation by causing a minute amount of chemical to be immediately absorbed into the vascular system of a plant at the time of cut. The system is most effective on stem diameters 3 inches and smaller and has a maximum application rate of about 2.5 gallons of herbicide mixture per acre.

The Toro Company’s Z Master G3 zero-turning radius mowers have been redesigned with a low center of gravity, the result of a vertical shaft engine that sits lower in the chassis, a lower operator position and the 12-gallon fuel tank that is now located under the operator’s seat. The combination provides hillside stability and traction for better control and less “crabbing.” The design also incorporates unitized hydros. The new instrument panel on G3 models contains an electronic hour meter and allows operators to quickly assess the status of the mower, including fuel levels and battery voltage.
