Next generation crawler excavator
LiuGong Machinery says its 922E next generation crawler excavator features additional power and control, a 5-percent improvement in operating efficiencies, and an 8-percent reduction in fuel consumption. The machine’s Intelligent Power Control System increases digging force by up to 10 percent for 10-second intervals. The no-time-limit, heavy-lift system enables the operator to increase pressure to build force and reduce hydraulic flow to the attachment, while reducing speed. An automatic boom-descent regeneration system allows the boom to descend faster. A multi-working-mode selection system gives the operator the ability to match performance with the job. The excavator is powered by a Cummins QSB6.7 diesel engine rated at 127 kW. Visit www.betterroads.com/info.

Other features include a K-Bogie undercarriage, Palm Command Control System, Komtrax Plus, and a low dB(A) noise level. Visit www.betterroads.com/info.
Non-destructive concrete moisture meter
The TQC Concrete Moisture Meter is a non-destructive moisture meter for concrete, which measures electrical impedance through the moisture content of concrete by pressing the instrument against the concrete surface. The electrical impedance is measured through generating a low frequency electric field between eight electrodes at the bottom of the instrument. Depending on the moisture content the measurements are made to a depth of several centimeters. Four scales allow flexible use of the instrument as an accurate measuring device or as a detector to find moisture traces or leakage: Concrete zero to 6 percent H2O; carbide method zero to 4 percent H2O; relative scale zero to 100 percent; and Scale 0.3 to 15.3m. The scale works in a similar way as the Relative scale and can be used alongside meters with the same scale that ranges between 0.3 and 15.3 meters. Visit www.betterroads.com/info.

Widest sweep path
Vacall’s AllSweep is the industry’s widest sweep path and a single-engine design, according to the manufacturer. An independent test shows All Sweep has the greatest air flow capacity when compared with all vacuum sweepers designed to clean up runways, parking lots, event venues, highway millings and streets, according to Vacall. Either single- or dual-sweep systems are available, as well as full-width nozzles and gutter brooms. A new position memory feature allows the nozzle height to be raised and then restored when encountering curbs, speed bumps and other obstacles. When in use, a new hydrostatic drive system controls chassis travel speed while maintaining a specific rpm level. The models also are equipped with catch basin cleaner hoses.

The Role of Mechanical Clutches in Dampening Torsional Vibrations
Industrial manufacturer Eaton Corp. has published a new technical paper on how contemporary mechanical clutches can protect high-value drivetrain components from harmful torsional vibrations in commercial trucks. The one-page, two-sided, color document (item number CLWP0001) is available at www.eaton.com/roadranger. Titled, “The Role of Mechanical Clutches in Dampening Torsional Vibrations,” the piece describes how modern damper technology has evolved throughout the years to effectively reduce driveline resonance that is created naturally in any internal combustion engine. It also points out how modern dampers have been adapted to work especially well with today’s high-torque, low-speed engines, which increase the amount of vibration in the drivetrain. The paper includes information on how breadth of product, selecting the correct amount of friction material and the number of springs all factors. Visit www.betterroads.com/info.
