VOLVO COMPACT EXCAVATORSECR28, ECR38More care. Built in.

OUTSTANDING COMFORTWITHIN A SHORT SWING.Make the long working days easier. Test the VolvoModels ECR28 and ECR38. Short swing radiusexcavators with a real difference. They turn within thewidth of their own tracks, ideal for tight job sites.Both models have a short swing radiussuperstructure so the counterweightturns within the track width. You can workin confined spaces, eliminating the risk ofhitting a wall or obstacles. Enhancedsafety on congested job sites is anobvious result.The spacious cab features an unclutteredfloor and a deluxe, adjustable suspensionseat with a high back and armrests toreduce fatigue. There’s excellent visibilitybecause of the large, glazed surface areaon all four sides, the thin cab pillars, thewide windscreen, and the compactengine cover. Exterior rearview mirrorshelp improve visibility and safety.The instrument panel features bothgauges and lights and is located withineasy view of the operator so he can keepan eye on all key machine functions.Both units feature easy-grip, highlyresponsive control levers mounted to theseat for precise movement and lessoperator fatigue. The right control leveralso has a roller to control the accessorycircuit with the fingertips for bettercontrol of attachments. In addition,there’s a button on the front of thejoystick that sends maximum flow toaccessories such as breakers for betterproductivity. Short tail swing offers the ultimate manoeuvrability. Spacious cab help to improve productivity. Wide cab offers plenty of legroom for better comfort.The Volvo ECR28 and ECR38 aredesigned for low noise, both inside andoutside of the cab. The cab is placed onrubber mountings to help reducevibration and there’s high-performancesoundproofing foam that helps insulateagainst noise. In addition, the quiet, newgeneration Volvo engine has anextremely efficient exhaust system.As a result, the low sound levels helpreduce operator fatigue and increaseproductivity.2

Excellent performance even intight job sites. Controls provide easy, precisemovement. Wide cab, deluxe seat and 360ºvisibility.

OUTSTANDING PERFORMANCEAND ENVIRONMENTAL CARE.The ECR28 and ECR38 provide no compromiseperformance when using a Volvo short swing radiusmachine. Both models offer the same care andrespect for the environment that you expect from everyVolvo product.The model ECR28 and ECR38 are shortswing radius machines, perfect for useon tight job sites. More productivity,increased machine capabilities andimproved safety.Both machines have new-generationVolvo diesel engines that provideexcellent performance. In addition, theModel ECR38 also features directinjection for fast, efficient mixing of fueland air. Both models provide low exhaustemissions complying with the strictestlegal standards.To work more efficiently the ECR28 &ECR38 feature an auto-idling systemthat lowers the engine speed to idle ifthe operator controls are not used forfive seconds or more. The system returnsthe engine to the pre-selected speedonce the operator uses any control.The system can be disabled when youneed to warm the engine.The finger tip control for accessoriesenables the operator to progressivelyadjust the flow to the attachment formore precision.The load-sensing hydraulics are the besttechnology available, providing simplicityand efficiency. The speed of the hydraulicmovements depends only on the positionof the power-assisted, multi functioncontrol levers. Regardless of load andnumber of simultaneous cylindermovements. Instantly supplying only thepower to meet the demand. Smooth andprecise operation is a reality. New Volvo engine offers excellent performance. Auto-idling reduces fuel consumption and noise. Impressive breakout and tear-out force.The operator can move the machineforward or reverse whilst continuing todig, important when grading and workingin tight spaces.The ECR28 and ECR38 also featureimpressive breakout and tear-out forces,allowing them to power through thetoughest working conditions.4

Progressive finger-tip control ofattachments. Excellent reach to reducemachine positioning. Load sensing hydraulics forprecise movement.

ENDURING QUALITY THAT PROTECTSMAN AND MACHINE.The Volvo ECR series are built with durabilitythroughout. They will last for years and retain a highresale value. Safety is built in, to protect both theoperator and others working near the machine.They’re also easy to service to help ensure a longproductive life.The engine is located on the side of themachine and has a large hood that canbe opened wide for complete andunobstructed access to all routine servicepoints, including filters and fluid levels.The fuses are grouped together in theengine compartment, protected in a dustand damp-proof box for easy access.As with all Volvo products, the units offerthe best in safety features to help protectthe operator. Volvo cabs and canopiescome standard with a FOPS 1, ROPSand TOPS safety structure to preventinjury from falling objects, rollover ortipover. A standard safety belt keeps theoperator fully in his seat.There are many high quality features toensure a long life, such as bucketcylinder hoses that are protected on theinside of the dipper. The ORFS (O-RingFace Seal) technology of the hydraulicconnectors provides a leak-free joint.The O-Rings provide excellent resistanceto pressure peaks, vibrations and twisting.The wiring looms and connectors meethigh standards, protecting the cablesfrom their harsh operating environment.Attention to detail has put the instrumentpanel where it is easy for the operator tosee, making efficient operation a reality.The cab door can be locked open and itis protected on the inside of the chassisto prevent damage. Open door is protected in the width of the chassis. Laminated windscreen increase operator safety. High quality electrical and hydraulic connections.The laminated windscreen is made of twopieces of glass bonded together with aclear plastic sheet in between. If thewindscreen breaks, it stays in one piece.All machine controls are locked out whenthe console is raised to help prevent therisk of an accident when the operator isgetting into or out of the cab.6

All controls lock out whenconsole is raised. Instrument panel provides clearview of functions. Side engine hood opens wide foreasy service.

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.

The Volvo ECR28 and ECR38 are designed for low noise, both inside and outside of the cab. The cab is placed on rubber mountings to help reduce vibration and there's high-performance soundproofing foam that helps insulate against noise. In addition, the quiet, new-generation Volvo engine has an extremely efficient exhaust system.
