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.
