Volvo Construction Equipment has introduced the ECR145D and ECR235D short swing radius excavators designed for maneuvering in and out of confined areas.

Both models feature new engines that meet the latest Tier 4-Interim emissions legislation. They also offer improved hydraulics and pump flow to help provide faster cycle times and better digging performance, Volvo says.

Featuring a narrow body design and centrally positioned boom, the superstructure on both models is so compact that its rear swings only fractionally outside its own track width. This means that the excavator can get extremely close to objects without risk of collision with the rear of the machine as it swings. Even when not working close to obstructions, the short front/rear radius has other uses, such as on highways, where the machines can swing within a typical single road lane width, minimizing disruption to the traffic flow.

Available with a mono or two-piece boom, several arm configurations and an optional blade, the ECR145D and ECR235D also feature reinforced, three-piece, high-tensile steel X-shaped frame undercarriages. Both machines are offered with a quick coupler option and an extensive range of Volvo attachments. The ECR145D is fitted with a  four-cylinder diesel engine that produces 114 horsepower while the ECR235D comes with a six-cylinder unit producing 173 horsepower. Both units are fitted with precise, high-pressure fuel injectors, turbo charger, and air-to-air intercooler, as well as electronic engine controls to optimize machine performance, according to Volvo.
