Models EC340D, EC380D and EC480D heavyweight production excavators feature Tier 4-I Volvo D13-T4(A) engines and range in weight from 75,000 to 111,000 pounds.
Volvo Construction Equipment models EC340D, EC380D and EC480D heavyweight production excavators feature Tier 4-I Volvo D13-T4(A) engines and range in weight from 75,000 to 111,000 pounds. Automatic idling system reduces engine speed with levers and pedals are not activated. Heavy-duty undercarriage on the EC380D and EC480D has thick-gauge metal plates, track guards, and bolt-head protection. The undercarriage is made from high-strength tensile steel; the sprocket and top rollers are made from forged steel and deep hardened for long term durability. Heavy-duty booms are standard, and high-strength tensile steel arms have wear strips welded to the inside.
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 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.
Models L60H, L70H, and L90H wheel loaders meet Tier 4-Final standards with a Volvo D6J diesel that delivers 165, 170, and 184 horsepower, respectively.
