More care. Built in.VOLVO COMPACT EXCAVATOREC20B XT, XTV

DIG IN TO SOLID PERFORMANCE.When you want a strong and reliable compactexcavator to meet your toughest demands - lookto the Volvo EC20B. Its compact design is big onversatility, comfort and performance. Built for easyoperation and maintenance, it’s the most costeffectivebusiness investment you’ll ever make.Move with precisionThe Volvo EC20B is also built forprecision work. Utilizing the besttechnology available, the closedcentreload-sensing hydraulic systemdelivers precise control under anycondition. Hydraulic speed relies onlyon the position of the control lever,regardless of the load or number ofmovements. This quality allows you tocombine all machine movements forfine precision and more productivework.Increase your speed andproductivityThe units also feature two travelspeeds for fast cycle times that saveboth time and money. The exclusivequick coupling system lets you easilyconnect an attachment or bucketright from the cab for increasedspeed and efficiency.Compact by designThe hydraulic offset of the boomreduces the overall excavatordimensions, helping you work in tightspaces and alongside walls. Inaddition, the wrap-around shape ofthe counterweight providesprotection against rear impact.Built strongThe EC20B features a double-yokepivot that doubles the bearing surfaceon the chassis. There is also a longpin that distributes the stress, forreduced wear and longer life. Theboom and dipper structuresincorporate cast steel parts on heavilystressed areas. Sturdy steel platesprotect all hydraulic connectors. Forreduced operating costs, a hydraulicmotor drives the crown gear directly,without a reduction gear, offering nowear or play. Heavy-duty towing andanchor points make craning jobseasier. An optional anti-theft keypadlocks the machine’s starting andhydraulic function for added safety.Jobsite flexibilityThe variable-width chassis offers thechoice of two cost-effectiveproduction options. Choose theexceptional stability of an extra-widechassis or the versatility of a machinethat can fit through small spaces, withan overall width reduced to less than1 m. The 250 mm wide tracks offerexcellent stability, traction and longlife. For increased flexibility, the bladesystem offers two side extensions.Each blade can be fitted or removedwithout tools to save time and money.• Extendible track and blade.• Two-speed travel for greater mobility.2• Quick coupler for fast, easy changes.

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

That’s why the EC20Boffers you all of the above and more: a productive,reliable machine that’s easy to keep running. Get themost out of each day in the machine designed for youand your work.Comfort built inQuiet operation is key to operatorcomfort and environmental control.That’s why the Volvo EC20B has aquiet, low emission engine with plentyof power. Superior soundproofinghelps reduce operator fatigue. Short,responsive drive controls avoidexcessive movements for easieroperation. Gauges are in front of theoperator to keep track of keyfunctions. Well-positioned armrestsmake long shifts more comfortablewhile ensuring precision control. Thevinyl covered adjustable suspensionseat offers comfortable all dayoperation.More room insideWhile the Volvo EC20B is compact,the cab is large and roomy for a moreefficient work environment. The largeflat floor provides plenty of legroomand storage space. Even tall operatorswill feel at ease in the ergonomic cab.In addition, the hydraulic attachmentcontrol pedal folds away when not inuse and can be positioned to the rightfor easy access and optimal operatingspace.A new view on safetyYou’ll have 360° of visibility forexcellent jobsite command. Theround, compact engine cover hasimproved rear visibility for bettersafety on narrow or congested sites.Non-slip steps and floor provide safe,easy entry and exit. The cab dooropens wide and the console swingsup and out of the way for a safer exit.The gas strut assisted window openseasily and the right side window slideopen wide for greater visibility andcomfort. There’s a standard seatbeltfor added safety and FOPS 1, ROPSand TOPS certified cabs andcanopies for maximum protection.Maintenance made easyThe EC20B is easy to maintain formaximum uptime. Unlike many othercompact excavators, its unique tiltingcounterweight and wrap-aroundshape provide total engine accessand optimum rear protection. Thehydraulic oil cooler is mounted on asliding support allowing better accessto cleaning cooler fins.The fuel supply circuit has atransparent at-a-glance pre-filter andfeatures a self-priming electric pump.When working in confined areas, thetwo consoles on the canopy versionlift for access from the right or left. Allboom supply hoses are loose fittedand connect on the outside of themachine for less wear and damage.• Perfect accessibility of the hydraulics compartment.4• Spacious and comfortable cab.

Volvo Construction Equipment is different. It’s designed, builtand supported in a different way. That difference comes from anengineering heritage of over 170 years. A heritage of thinkingfirst about the people who actually use the machines. About howto help them be safer, more comfortable, more productive. Aboutthe environment we all share. The result of that thinking is agrowing range of machines and a global support networkdedicated to helping you do more. People around the world areproud to use Volvo. And we’re proud of what makes Volvodifferent – More care. Built in.All products are not available in all markets. Under our policy of continuous improvement, we reserve the right to change specificationsand design without prior notice.
