TOOL DUST FILTRATION
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

ON-HIGHWAY VEHICLE AIR COMPRESSOR
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

HYDRAULIC OIL ANALYSIS
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
