Volvo Construction Equipment is introducing two new compact excavators to the North American market, namely the 3.7-metric-ton EC37 and the 4-metric-ton ECR40. These models are set to replace the EC35D, ECR35D, and ECR40D in Volvo's existing lineup. Although the EC37 and ECR40 share the same platform and components, they differ in their swing radius, with the EC37 featuring a conventional tail swing and the ECR40 having a shorter tail swing radius.
Both excavators are powered by Volvo's 24.8-horsepower diesel engines, designed to meet Tier 4 Final emissions standards without the need for a diesel particulate filter. The new engines are now equipped with an ECO mode, and they boast auto engine shutdown and auto engine idle features. Auto engine shutdown discontinues engine operation after idling for more than 4 minutes when stationary and not in gear, resulting in a 10% increase in fuel efficiency and reduced maintenance costs.
Volvo has enhanced the cabs of these compact excavators, making them more spacious, ergonomic, and quiet. Improved operator visibility is achieved through slim corner pillars and wide flat glass areas. The armrests and controls move with the seat, and the foot pedals area and door areas have been enlarged. Operators can navigate modes using a jog dial and customize hydraulic settings, which can be saved on the touchscreen for multiple operators.
Load-sensing hydraulics have been incorporated for smoother movement, and optional features include a hydraulic thumb operated by a proportional roller on top of the joystick, a float blade, and LED work lights. To enhance stability, Volvo has extended the undercarriage for both the EC37 and ECR40, providing longer contact between the tracks and the ground to minimize the "rocking chair effect" sometimes observed in compact excavators.
In terms of service, Volvo has extended greasing intervals to 50 hours, and the engine and rear hood openings have been widened for easier access.
