Komatsu introduced three new Dash 10 excavators: PC240LC-10, PC360LC-10, and PC490LC-10. Each has Tier 4-Interim engines with 177, 257, and 359 horsepower, respectively. The PC240LC-10 weighs 55,000 pounds; PC360LC-10, 79,000 pounds; and the PC490LC-10, 108,000 pounds. Hydraulic systems have all-new componentry, including engine, pumps, motors and valves. The integrated design uses a closed center load sensing hydraulic system that matches engine speed to pump output for both light- and heavy-duty applications. Cabs have been mounted on viscous damper mounts for reduced vibration, and high-back, adjustable seat uses air suspension. Circle xxx on the reader service card
Extending an industry trend that targets lower-hour users with less expensive, base machines that stay under 75 horsepower to avoid DEF aftertreatment, Caterpillar has introduced the 313F L GC hydraulic excavator, a companion unit to the higher-spec'd 312E L.
The Cat 336F L XE Hybrid hydraulic excavator captures and reuses energy, delivering an estimated fuel savings of up to 20 percent compared with its standard 336 counterpart.
Komatsu’s 264-horsepower D85-18 crawler dozer, aimed at large construction operations and small mining customers, features a Komatsu SAA6D125E-7 variable geometry, turbocharged and aftercooled Tier 4-Final-certified engine that the company says burns up to 5 percent less fuel.
The D155AXi-8 is another of the company’s intelligent machine control dozers that allows automated operation.
