Scheduled to debut at the 2009 World of Concrete, Liebherr’s R924 Compact Swing excavator sports the newly developed Liebherr D936S Tier 3-compliant diesel engine.
Liebherr R924 Compact Swing excavator sports the newly developed Liebherr D936S Tier 3-compliant diesel engine. Despite its compact body, the R924 is a full-size excavator rated at 163 horsepower, meaning the machine is suited to work in all terrains. But the 6-foot swing radius also enables the R924 to maneuver in tight spaces. Routine maintenance can be done easily thanks to all service points being centrally located and accessible from the ground; It also has an automatic lubrication system. Hydraulic quick-coupler system accepts attachments for grading, trenching, truck loading and more.
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.
The 126,000-pound R 956 excavator replaces the R 954 and features improvements to the upper carriage’s steelwork to extend service life.
Model A934 HD ERC Material Handler has Liebherr’s patented Energy Recovery Cylinder (ERC) and Liebherr Power Efficiency (LPE) system to increase production by 5 percent, reduce fuel consumption by 20 percent, and improve sound levels by 2 decibels when compared to its predecessor.
