STRESSING JACK Promoted by the manufacturer for safe and fast operation in precast/prestressed concrete fabrication, the Paul U.S. 250kN jack is equipped


Promoted by the manufacturer for safe and fast operation in precast/prestressed concrete fabrication, the Paul U.S. 250kN jack is equipped with an internal grip that automatically grabs strand when it starts to extend. Once threaded into the jack, the strand is kept in the center, preventing the jack from tilting during stressing and making it safer to operate than traditional pull-type models. The jack head has a hydraulic lock-off cylinder to provide secure power seating of the anchor wedges. The hydraulic locking head also allows the use of inexpensive, multiple-use open chucks.

The Eliminator filtration system for concrete surface grinding allows attachment of any tool in order to reclaim dust at the source. Standard oversized filters are 99.9 percent efficient at 0.5 micron; HEPA filtration is an option on any vacuum for 99.97 percent efficiency at 0.3 micron.

The portable Eliminator system uses three high-powered vacuum motors for increased suction and airflow. A high-efficiency cyclone removes 98 percent of the dust, the manufacturer notes, depositing it into a 30-gal., self-bagging collector for easy machine emptying. The system suits multi-operations, 7-in. grinders with 25-ft. hoses, crack saws, and larger floor grinders. When the vacuum is disconnected and used alone, ultra-fine dust missed by the high-efficiency cyclone is captured by the 28-sq.-ft. filter and can be removed simply with the drop-down dustpan.

The B.E.P. System-HG Û reportedly the world’s first hand- and gang-set aluminum form panel system Û and the Quick-Tach Window Buck Panel and Frame System debuted at the 2006 World of Concrete. The System-HG suits residential or light-commercial construction; can be set in an individual or gang panel format; and is compatible with all other forming systems. It is produced in smooth, all-brick finishes as well as Georgian stone and adobe brick with all popular hole patterns. Its heavy, flat, 2-in. side-rail construction eliminates concrete leakage and bowing. The new system can be ganged together with the company’s Quick Clamp/Whaler Bracket System, and every panel features the reusable Power Taper Tie System, reducing standard wall tie replacement costs.

The Quick-Tach Window Buck Panel and Frame System allows residential or commercial contractors to install egress or above-grade window frames in seconds, as it slides into position and locks into place, eliminating shift during pours and the need for nails, self-tapping screws and other methods traditionally used to secure frames. Fully adjustable up to four feet in either direction, the frame can be installed from one side, resulting in perfectly centered windows as well as reduced labor costs. B.E.P. Forming Systems

The 270 model is designed to provide cleaner air along with what product engineers note are greater reliability, significantly less vibration and quieter operation. The new air compressor was released in April on the company’s C13 engine and will be widely available in 2007.

The 270 uses two cylinders for better balance that reportedly impart significantly less vibration in selected chassis. Product developers assert that noise is up to a full two decibels lower than competitive models, while the new air compressor is even more effective at supplying air. Reliability and durability also are enhanced by a cast iron piston, they add. Moreover, installation of the compressor is simplified by fewer required parts and hardware. Additionally, the Cat 270 will reportedly offer better oil control to minimize oil carryover that degrades cleanliness of the air supply. Longer head bolts and full-length, water-cooled cylinder bores provide optimum clamp loading and cooler discharge air for reduced bore distortion and improved oil carryover. Caterpillar Power

Allowing contractors to make large cuts with little effort, the manufacturer notes, the new CS-7060 walk-behind saw features stay-level handles that remain level regardless of the saw’s operating position. Coupled with the saw’s moving center of gravity for optimal balance in all cutting applications, these handles minimize operator fatigue and significantly reduce the risk of back injury while boosting productivity, according to product developers. Fueled by a 60-hp Deutz diesel engine, the CS-7060 saw has a 36-in. blade capacity and a maximum cutting depth of 15 inches. The unit weighs 1,725 lb.

The CS Series pavement saw features a patent-pending clutchless bladeshaft disengaging system, whereby the bladeshaft rotation can be stopped or started with a flick of a switch while the engine is running. Safety is thus improved for the saw operator and others within the immediate area, while eliminating the risk of damage to the saw or blade. The saw also incorporates a vibration-control mounting system to cut handle bar vibration, minimizing related injuries and extending component life. Stow Construction Equipment

Quarterly testing for pump operators offers what the company notes is inexpensive insurance against premature component wear. The Analysis Kit includes a sample bottle, simple questionnaire, and prepaid mailer. Testing involves extracting an oil sample as instructed, packaging it, and dropping it in the mail. Owners receive a particle and water content report, plus recommendations based on the concrete pump’s parameters. Online reports also highlight the severity of results, oil viscosity, and a photomicrograph of actual system contaminants. Although oil analysis does not replace regular maintenance, the manufacturer contends, regular testing can extend the life of a pump and prevent costly downtime. Schwing America

Montreal-based Scale-Tron Corp. and Sicoma (Societ∑ Italiana Costruzione Macchine) of Perugia, Italy, have announced a line of mixers and mix delivery equipment available through a North American venture formed last year. Sicoma’s products include twin shaft, planetary/countercurrent, turbine and continuous mixers, plus overhead handling systems such as side rail traveling hoppers, flying buckets and traveling, swiveling conveyors. In combination with Scale-Tron’s plant-control technology and iron from allied company, McCoy Equipment, Sicoma North America is providing new plants and upgrades for existing facilities. Product offerings include:

Twin-shaft mixers Û The MAO series twin-shaft mixer has fast spiral mixing action, giving it the ability to produce concrete quickly and at high cement binding efficiency. In addition, it has the most heavily reinforced frame in the industry, company representatives note, eliminating distortion under heavy load, which can twist and destroy shaft seals and bearings in lighter models. Its belt reducer and two-stage planetary gearbox reportedly runs cooler than others, requiring no separate oil cooler, even for continuous 24/7 duty. The manufacturer cites other standard features, including more paddles, extra-hard liner plates with offset joints for reduced wear, electric variable-flow grease pump, fluid level and temperature alarm monitor, easy-access single-day shaft and bearing replacement, plus air-purged shaft seals. Options include power washout, reduced-size discharge and double discharge doors. Sizes range from 3 to 12 yd. with hourly output from 80 to 320 yd.

Planetary mixers Û The MP series planetary/countercurrent mixer offers what company officials note are time and materials savings. All models have a generous pan size, enabling them to mix small or large batches with equal ease Û up to their full capacity Û as well as a large reduction gearbox whose oversize gears provide cool running and extra-long life. Up to four discharge doors can be fitted, all with waterproof rubber seals and eccentric nonjamming action. Angled for optimum wear, three-blade-equipped mixing arms can discharge a full-capacity load in 20 seconds; and, tight clearances for all moving parts facilitate cleanout. Other features include integrated water distribution that doubles as a washout system and a one-piece half-moon hydraulically raised cover that gives access for cleaning and adjustments. Sizes ranging from 0.1 to 5 yd. yield up to 110 yd./hour.

Traveling hoppers Û Flying buckets and discharge systems suit wet and dry cast operations. The side rail traveling hopper runs on two rails arranged vertically, allowing cranes and other equipment full freedom of movement up to the plant wall, while traveling, swiveling conveyors feed through walls to an adjacent bay. Other products such as flying rollover buckets, crane-bridge mounted hoppers and pneumatically operated buckets deliver concrete up 25-degree gradients and around tight bends to multiple casting stations. Combined with the company’s SmartControl wireless communication system, the overhead handling systems are said by product developers to offer fast and reliable service, as evidenced by many years’ field testing in Europe.
