More power and efficiency with Volvo D-Series



D Series Excavators

The new D-Series excavators from Volvo Construction Equipment have the strength and durability to take on a range of challenging worksite tasks. With faster cycle times, excellent digging and lifting capabilities, and a capacity for greater productivity, the EC220D, EC250D and EC300D have  what it takes to get the job done in a low-stress, high-performance way — every time.

Increased power and digging force as well as faster cycle times offer operators the prospect of greater productivity. Compared to the previous models, hydraulic pump flow has improved by 3 to 5% while digging force, swing torque and tractive force have increased by between 3 and 6%. In the EC300D, engine power has increased by an even healthier 11%.

Each excavator is equipped with a powerful six-cylinder diesel engine, which complies with regional emissions regulations. Maximum power is 123 kW (167 hp) for the EC220D, 138 kW (188 hp) for the EC250D and 170 kW (231 hp) for the EC300D. 

Volvo’s unique integrated work mode system now includes G4 mode for optimum fuel efficiency and machine performance. Operators can choose from a selection of five work modes — idle, fine, general, heavy and power max mode — to suit the task at hand.

The ability to adapt to the worksite allows for more precise performance, but also promotes a more efficient use of fuel. Volvo’s unique ECO mode contributes to up to 5% of the machine’s total improved fuel efficiency – without any loss of performance in most operating conditions. The design features electronic pump control technology which reduces flow and pressure losses while maintaining digging power and maximizing swing torque. The machines’ optimized hydraulic piping further improves fuel efficiency. A new gauge bar on the I-ECU measures instantaneous fuel consumption while average fuel consumption is displayed numerically per hour. This allows operators to monitor fuel use on different job sites and applications.

Performance can be further matched to the task by an attachment management system, which stores up to 20 different attachment presets. This allows hydraulic flow and pressure adjustments to be accurately set, according to the needs of the tool being used, at just the touch of a button.

Sensing squared
A new electro-hydraulic system and main control valve use intelligent technology to control on-demand flow and reduce internal losses in the hydraulic circuit. This provides increased controllability, shorter cycle times and improved fuel efficiency. Thanks to the smart hydraulic system’s greater controllability, both grading and combined operations have been improved. Operators benefit from smoother and easier movement when traveling and lifting simultaneously, as well as better grading quality from the harmonized boom and arm movement.

The boom float frees up hydraulic flow by lowering using gravity only, and a boomdown/arm-in/bucket-in regeneration system diverts oil from the cylinder piston side to the cylinder rod side – resulting in faster, more efficient digging.

For greater productivity, D-Series excavators come equipped with the latest generation cab, which offers users excellent visibility, ideally placed controls, and a quieter, spacious, safer and more comfortable place to work. The new color LCD I-ECU monitor displays the machine’s status, informing operators of fuel consumption and alerting them to upcoming maintenance tasks. It also controls the attachment management system. The D-Series excavators come as standard with climate control systems with 14 vents, so operators can customize the cab’s interior temperature for greater comfort.

Tough as nails
Made from thick-gauge, high-strength tensile steel, the heavy-duty undercarriages are built to withstand all the rigors of the job site. 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. Durable three-stage planetary gearboxes and automatic two-speed track motors are used, while improved performance over difficult or steep terrain is evident, due to increased tractive force.

A robust boom and arm is made from high-tensile steel and robotically welded for severe-use durability — it’s heavily reinforced to withstand working with materials like blasted rock. Wear strips welded to the arm give added protection, while the linkage yoke features a support bar for additional strength.

D-Series excavators feature easy maintenance. Accessed via wide opening compartment doors, grouped, ground-level filters and service points are simpler and safer to get to. Checks are done quicker, further improving uptime, while a service mode on the monitor in the cab allows technicians to easily perform diagnostic checks. (The monitor can also display the view from the rear-facing camera.) Large doors and engine hood can be fully opened for convenient access to components. Centralized filters and greasing points allow regular checks to be completed quickly and easily for maximum uptime and productivity. Anti-slip steel plates ensure safe maintenance access, even in wet weather.

The D-Series excavators are available with a comprehensive choice of service plans from Volvo’s dedicated dealer network, ranging from routine wear inspections to full service agreements and Eco Operator training. And as with all Volvo products, the DSeries excavators are backed by an extensive service network that provides the peace of mind that comes with an extensive, worldwide infrastructure of technicians, workshops and dealers.
