Volvo EC140D, EC160D and EC220D excavators are up to 14-percent more fuel-efficient with Tier 4-Interim engines and offer up to 7 percent more gross horsepower.
Volvo EC140D, EC160D and EC220D excavators are up to 14-percent more fuel-efficient with Tier 4-Interim engines and offer up to 7 percent more gross horsepower. Greased and sealed track chains are standard, and a new rear access located behind the cab of the EC140D and EC160D models allow better reach to the main hydraulic components and engine. Operating modes include I-idle, F-fine, G-general or H-heavy with the machine automatically setting the appropriate engine speed for the work mode. Eco mode is a new feature that works in H or G mode and provides better fuel efficiency without loss of performance in most operating conditions, the company says. The “smart” hydraulics system features improvements that increase total flow and improve cycle times up to 2.5 percent. An attachment management system can store up to 18 pre-sets and enables hydraulic flow to adjust to meet the requirements of the attachment in use. Units come standard with Volvo CareTrack.
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 EC380EHR and EC480EHR high-reach demolition excavators have a sturdy undercarriage and a working range over 360 degrees
The 22-ton EC220E crawler excavator has a 172-horsepower, Tier 4-Final Volvo D6 engine that delivers 5 percent better fuel efficiency compared with the C Series predecessor.
