EquipmentWorld.com | August 2015 21 marketplace | by Amy Materson | AMaterson@randallreilly.com FUEL SAVERS Work in confi ned spaces without sacrifi cing power, dig depth or stability with Volvo Construc- tion Equipment's E-Series short swing crawler excavators, which feature a center-posi- tioned boom and compact swing radius. The ECR145E and ECR235E have Tier 4 Final engines that de- liver up to 10 percent improve- ment in fuel economy when compared with previous models, and include auto idle. The excavators can be equipped with an optional engine shutdown feature that further improves fuel effi ciency. Both machines have integrated working modes that enable the operator to choose the best work mode for the application: idle, fi ne, general or heavy. When designing the crawler excavators, Volvo addressed lowering the total cost of ownership via an enhanced hy- draulics system that combines with the fully electronic control system to improve response time and controllability. Work- ing with the Volvo ECO mode to reduce fl ow and pressure losses, the system achieves lower fuel consumption. Safety has been addressed through the use of punched anti- slip plates and handrails that ensure grip while performing maintenance checks. Foldable guardrails offer safe access. The cab is newly designed, featuring large front and side windows to ensure high visibility. Ad- ditional cab features include an improved climate control system, new air circulation and defrost- ing system, a keypad that allows operators to navigate through monitor settings to activate ma- chine functions, Bluetooth and shortcut buttons for windshield wipers, camera and an audio mute function.
