Volvo Introduces Cleaner and More Productive D-Series Heavyweights

Fri August 26, 2011 - National Edition
Construction Equipment Guide

Part of the new generation D-Series of excavators, Volvo Construction Equipment is offering North American customers three heavyweight production machines, ranging in weight classes between 75,000 to 111,800 lb. (34,019 to 50,711 kg). Meeting the strict requirements of new EPA emissions legislation, the powerful and reliable EC340D, EC380D and EC480D excel in heavy digging and lifting duties, offering superior cycle times and greater fuel efficiency, according to the manufacturer.

The D-Series offers more powerful Tier IVi-certified D13 Volvo engines, delivering lower emissions and enhanced fuel efficiency. These engines work in harmony with intelligent, advanced hydraulics and feature a more rugged undercarriage.

Built for heavy production duties such as trenching, loading, moving rocks or general construction, the EC340D, EC380D and EC480D deliver dependable power with high torque, along with lower emissions, fuel consumption and noise.


At the heart of these machines is a turbocharged high pressure direct injection Volvo diesel engine that offers maximum power of 279 hp (208 kW) (EC340D/EC380D), and 343 hp (256 kW) (EC480D) respectively. All three machines feature an automatic idling system that reduces engine speed when the levers and pedals are not activated — aiding fuel efficiency and lowering external noise.


When only a single function is being used, the two pump hydraulics system combines the flow of both pumps for quick cycle times and greater productivity. It also can prioritize flow according to the work being done — e.g. to the boom for faster raising when loading or in deep excavations or to the arm during leveling duties.


“Heavy duty” is the best way to sum up the EC380D and EC480D, with thick gauge metal plates, track guards and bolt-head protection offering durability in tough working conditions. 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. Bottom rollers feature extreme pressure (EP) oil, reducing the oil temperature and ensuring consistent viscosity, even under heavy loads.

Improved performance over difficult or steep terrain is possible due to increased tractive force. The larger EC480D features mechanical variable width tracks, which extend the width by 6 in. (15 cm) and raise clearance by 8 in. (19.6 cm), aiding stability and protection.

Boom and Arm

Heavy duty booms are standard on these machines, and high strength tensile steel arms provide durability in severe applications. Wear strips welded to the inside of the arm give added protection and the linkage yoke features a support bar for additional strength. The optional boom float function lowers the boom using gravity only, freeing up hydraulic flow for other duties.


The operator can select the work mode, settings and attachment requirements all from inside the cab. Four working modes (idle, fine, general and heavy) allow operators to quickly select the best mode for the job at hand. This automatically tailors the performance and ensures the best fuel efficiency. Up to 18 different attachments also can be managed, tailoring hydraulic flow and (as an option) pressure according to the specific requirements of the tool being used.

Using Volvo’s ROPS-protected care cab, operators sit in a roomy, low fatigue, air conditioned working environment, with clear visibility and controls that are easy to handle. A large, clear color monitor gives operators all the important machine information, while a service mode allows technicians to perform diagnostic checks. The monitor also can display the view from the rear facing camera.


The EC340D, EC380D and EC480D all feature easy maintenance. Accessed via wide opening compartment doors, grouped, ground level filters and service points. Simpler and safer access. Checks are done quicker, further improving uptime, while a reversible cooling fan is operated from the cab and helps prevent radiator clogging and overheating problems.


These machines come fitted as standard with CareTrack, Volvo CE’s telematic system. Accessed remotely, CareTrack provides machine information such as fuel consumption and service reminders that allow improved planning and operation. A comprehensive range of service plans also are available from Volvo’s dealer network, ranging from routine wear inspections to full service agreements and Eco operator training.
