LIUGONG

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.

JET

New hydraulic detachable gooseneck trailers

Jet’s hydraulic detachable gooseneck trailers 35-ton and 51-ton series now come in various models and a variety of front and rear deck heights. The 35-ton model comes with a tandem or triple axle while the 51-ton model allows for a triple or quad axle. Standard features include air ride suspension, a low deck height, hydraulic gooseneck, adjustable ride height, heavy-duty tie downs, non-ground bearing, and a hydraulic fame jack to support the gooseneck on a tractor frame. Fabricated I-beams allow for optional 5-1/2-inch aluminum I-beam slide outs on the 35-ton series while heavy-duty outriggers may be incorporated on both the 35-ton or 51-ton model.

CASE

Upgraded skid steers

Case Construction Equipment has upgraded its four largest Alpha Series skid steers and compact track loaders to meet Tier 4 Interim certification emission requirements. The Case SR250 and SV300 skid steers and TR320 and TV380 compact track loaders now feature 90-horsepower, 3.4-liter Case diesel engines with the full high-pressure common rail (HPCR) design typically used in larger construction equipment. The models are now equipped with cooled exhaust gas recirculation (CEGR) technology, including diesel particulate filter and diesel oxidizing catalyst. Rated operating capacities are 2,500 lb for the SR250; 3,000 pounds for the SV300; 3,200 pounds in the TR320, and 3,800 pounds for the TV380.

MUNCIE POWER

Real-time support, remotely

The Advantage + System from Muncie Power Supply has a built-in Real-Time Support Link allowing remote access to the system. A flow-sharing design allows for simultaneous equipment operation even at low pump flows. The touch-screen display is high-contrast, high resolution and multi-color. The system is useable with gear or piston pumps, has built-in pre-wet and anti-icing controls, menu-adjusted pressure controls and digital pressure displays, and operational data logging and diagnostic data logging. Built-in GPS, WiFi and interface and displays for road/air temperature sensors come as part of the system, and there are no wire harnesses between the cab controls and the valves.

HYUNDAI

Mid-size excavator with optimized safety

The newest addition to Hyundai Construction Equipment’s line of Robex 210, 9-Series crawler excavators is the R210LC-9. It features improvements that include optimized safety, enhanced technology and operator comfort, reduced operating costs, and extended component and wear-part life. The mid-size excavator is powered by a Cummins QSB6.7 water-cooled, four-cycle, low-emission diesel engine with 145 horsepower at 1,900 rpm. At 49,390 pounds, the machine has a dig depth of 18 feet, 7 inches and bucket digging force of 24,900 pound-feet. New steel-tube construction on the cab increases safety and durability. The excavator comes standard with a 7-inch-wide color LCD screen Cluster with toggle switch that allows the operator to select personal machine preferences, as well as power and work-mode selections, self-diagnostics, maintenance check lists, and machine security.

KOMATSU

A better dozer

Komatsu America says its D375A-7 dozer features technological enhancements for increased production, fuel economy, extended component life, and operator comfort. The company says the dozer offers more horsepower and features an optimized blade profile, an enhanced operator station, and key mining specifications. Standard operating equipment, such as torque converter lockup, track-shoe slip control, power/economy mode, and ripping penetration, are said to exceed critical customer requirements. 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.

TQC

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.
