EC15B XR, XTV EC20B XTV VOLVO COMPACT EXCAVATORS

2 SOLID AS A ROCK. • Quickcoupler for fast, easy changes. Today’s jobs demand efficient productivity. You want reliable, durable machines that are versatile, comfortable and safe. For machines that deliver on all your expectations - look to the Volvo EC15B/20B line. Each is compact, powerful and profitable. It’s Volvo quality through and through. You’re in control Get behind the controls of the compact line built for smooth, precision work. It starts with a powerful closed-center load-sensing hydraulic system, using the best technology available. The speed of the hydraulic movements depends only on the position of the control lever, regardless of the load or number of movements. This means you can combine all the machine’s movements for smooth, precise work and increased productivity. Make quick work of your jobs The Volvo EC15B/20B line moves from job to job as quickly as you do. With two travel speeds, you can save time and money with quick travel and fast cycle times. For the ultimate in speed choose the optional bucket quickcoupler. Change the bucket on the fly right from the cab. Small design, big production Get more done with a compact design that’s big on safety and production - even in the narrowest jobsites. The hydraulic offset of the boom reduces the overall excavator dimensions, helping you work alongside a wall. And the wrap- around shape of the counterweight provides excellent protection against all rear impacts. Rely on Volvo Nothing adds to profitability like reliability. The Volvo EC15B/20B line features a double-yoke pivot that doubles the bearing surface on the chassis. This enables a long pin to be fitted for a better distribution of stress with less wear and longer component life. The boom and dipper structures incorporate cast steel parts on all heavily stressed areas. Sturdy steel plates protect all hydraulic connectors. And for reduced maintenance costs, a hydraulic motor drives the gear directly, without a reduction gear - for no wear and no play. An optional anti-theft keypad locks the machine’s starting and hydraulic functions. Versatile performer With a variable-width chassis, Volvo offers the possibility of choosing at any time between two options. Choose the exceptional stability of an extra-wide chassis or the versatility of a machine that can fit through narrow openings, with an overall width reduced to less than 3.3 ft (1 m). And for increased flexibility, the blade has two side extensions, which can be fitted or removed quickly without tools. • Variable width chassis fits the job. • Two-speed travel for greater mobility.

3 • Comfortable ergonomic armrests. • Optimum load-sensing efficiency. • Versatile, powerful performance.

4 BIG ON COMFORT AND SAFETY. Operator comfort and safety always add to productivity, helping you focus on the job and get more done. Work-ready machines are the best way to get the most out of each day. That’s why Volvo Excavators are designed for fast, easy maintenance, all-day comfort and the safety you demand. Maintain top performance The Volvo EC15B/20B line is easy to maintain so you get maximum uptime. It starts with the unique tilting counterweight and its wrap-around shape. Unlike many other excavators, the Volvo tilting counterweight gives total engine access and optimum rear protection. The hydraulic oil cooler is mounted on a sliding support allowing good access for cleaning cooler fins. The fuel supply circuit has an at-a-glance transparent pre-filter and features a self- priming electric pump. Useful for working in confined areas, the two consoles on the canopy version can be lifted for access from the right or left. And for long life and easy replacement, all boom supply hoses are loose fitted and connected on the outside of the machine. Feel the comfort Quiet operation is key to operator comfort and environmental protection. That’s why the Volvo EC15B/20B line features quiet, low-emission engines with plenty of power. Superior soundproofing makes the jobsite more comfortable for everyone. Feel at ease with short, responsive drive controls that avoid excessive operating movements and reduce fatigue. All key instruments are grouped and placed within the operator’s line of sight. And with ergonomically designed armrests, the forearms rest comfortably for long shifts and precision control. Volvo gives you your space Although the Volvo EC15B/20B line is compact in design, it’s roomier than you think on the inside. The large, flat floor provides plenty of legroom and storage space. Even tall operators will feel at ease in the spacious cab. And to optimize space, the hydraulic attachment control pedal folds away when not in use and is positioned to the right for easy access. All around safety The operator’s cab features quick, safe access with non-slip steps and floor. The cab door opens wide and the console swings up out of the way. Enjoy 360° visibility for excellent jobsite command and protection of people and property on narrow or congested sites. The rounded, compact shaped engine cover also offers good rear visibility. And for safety and peace of mind, the Volvo EC15B/20B line features a standard seatbelt and FOPS 1, ROPS and TOPS certified cabs and canopies. • Perfect accessibility of the hydraulics compartment. • Spacious and comfortable cab.

• The EC15B and EC20B can easily be transported on a trailer. • Easy access for maintenance and service. • Large floor for comfort and storage. 5
