50 E&MJ; • MAY 2017 www.e-mj.com EQUIPMENT GALLERY ARDCO announced its Articulating Multi- Purpose Truck (AMT), featuring a modular back-end platform that can be custom- ized for off-road jobsites. It accepts an array of attachments. Available confi gura- tions include a bare chassis, fl atbed, wa- ter tank, fuel tank, dump bed, service and lube station, utility bed, personnel carrier, pipe trailer, drill, and custom solutions. Multiple tire choices help further confi gure the machine. Powered by a 250-horsepower (hp) Cummins QSB6.7 Tier 4 Final diesel engine, the AMT 600 features selectable 4- or 6-wheel drive with a maximum payload of 45,000 lb. The AMT 400 has a 200-hp Cummins Tier 4 engine, offers 2- or 4-wheel drive, and has a maximum payload of 28,000 lb. Top travel speed for each unit is 23 miles per hour. The AMT features a 2-person, ful- ly enclosed, all-weather ROPS cab. Both models include a Dana 6-speed power- shift transmission with twist grip shifter. www.ardcomfg.com Best-in-class 4-axle Crane Goes Green Liebherr released the 90-metric ton (mt) LTM 1090-4.2. It is the most powerful 4-axle crane on the market, the compa- ny reported. The crane can travel with an axle load of 10 mt, 12 mt and 16 mt. It features a 60-meter (m) telescopic boom, and carries 8.8 mt of ballast with a 12-mt axle load. A 6-cylinder Tier 4 Final Liebherr die- sel engine provides 330 kilowatts and 2,335 Newton-meters (Nm) torque. The ECE-R.96 engine is also available for countries with less stringent emission regulations. ECOdrive and ECOmode re- portedly reduce fuel consumption and noise emissions. Liebherr's VarioBallast and VarioBase also deliver improved per- formance, fl exibility and safety over prede- cessor competition, the company reported. www.liebherr.com Motors for Extremes Nidec Motor Corp. unveiled TITAN Totally Enclosed Fan Cooled (TEFC) motors for pumps, compressors, fans, blowers and conveyors. U.S. Motors brand TEFC mo- tors are designed to operate in 40°C and at a maximum altitude of 3,300 ft above sea level. They are rated Class B rise at 1.0 service factor and Class F rise at 1.15 service factor with full Class F or better insulating materials. Nidec conducts a short commercial test on each TITAN TEFC motor consisting of no-load current tests, and a check on locked rotor cur- rent, winding resistance, high potential and vibrations. TEFC motors are offered in 150 hp through 600 hp. Inventory is available and ready to ship on 150 hp through 400 hp motors. www.usmotors.com Non-Nuclear Density Meters Red Meters unveiled the RM Series, non-nuclear density meters. Coated with an abrasion-resistant liner to withstand rough and fi nely ground slurries, the RM3 is easily installed into the slurry pipeline. A Class 2 industrial laser reads passing materials continuously, which is then in- terpreted by the system's algorithm and displayed on the monitoring interface. Density is calculated with an accuracy of +/- 0.25% based on samples taken 50 times per second. The HMI touchscreen output can be set to display different vari- ables in numerical or graph form, includ- ing: density, pressure, percent solids, total- Basic Truck is Completely Customizable
