//--- META DESCRIPTION FOR BOOMTRAIN---//?>
Volvo says its newest short wing radius excavators offer both performance and productivity in confined spaces.
The ECR58D and ECR88D feature a narrow body design, centrally positioned boom and rear that swings within its track shoe. The D-Series excavators have automatic two-speed travel and hydraulic travel pedals, a joystick that controls slew and offset movements simultaneously and a three piece high tensile steel X-shaped frame undercarriage.
Both excavators have Tier 4 final, four-cylinder engines that produce 50 and 58 horsepower, respectively, with an exhaust aftertreatment system that delivers lower emissions and seamless operation during regeneration. An auto-idle system reduces the engines speed based on a 3- to 20-second period pre-set by the operator.
The excavators are available in a range of configurations including mono-boom or optional two-piece boom on the ECR88D, as well as several arm and blade choices.
Max digging reach is 19 feet 8 inches (short arm) or 20 feet 11 inches (long arm) on the ECR58D, and 22 feet 10 inches (short arm) or 24 feet 1 inch (long arm) on the ECR88D. The ECR58D offers a max dig depth of either 11 feet 7 inches or 12 feet 11 inches, and the ECR88D provides a dig depth of up to either 13 feet 7 inches or 14 feet 10 inches, depending upon arm configuration.
Operator comfort is addressed via an adjustable seat, vibration and noise insulation, ergonomic armrests and more. The ROPS-certified cab has large areas of flat glass for improved all-around visibility. With respect to maintenance, all of the excavators’ service and cleaning points are ground-level accessible under a large lockable hood.
