New generation upgrades to the 35-tonne Volvo ECR355 short swing excavator bring faster cycle times and smoother precision for trenching and backfilling, the Swedish manufacturer claims, with increased fuel savings over the previous model.
A new electro-hydraulic control system and redesigned main control valve combine to deliver up to 7% greater fuel efficiency than the previous generation ECR355. The system uses electronic sensors and the machine’s onboard computer to optimise flow and pressure, ensuring smooth and precise control of the boom, arm and bucket movements.
Electric cooling fans operate only when needed, minimising engine load, noise and fuel consumption. Operators also benefit from additional efficiency-enhancing technologies, including new engine work modes, Comfort Driving Control (CDC), hydraulic priority setting and automatic engine shutdown, which all contribute to lower running costs and higher uptime.
The new ECR355 also offers a 7% increase in rated lifting capacity and 4% more tractive force.
Volvo’s Active Control system automates boom and bucket movements for up to 45% faster grading with less rework and fatigue, the manufacturer says. Integrated boundary limits and Dig Assist apps support 2D/3D machine control and in-field design. Features like boundary limits, boom/swing priority functions, and a floating dozer blade aid speed and precision.
Volvo’ Smart View with People and Obstacle Detection uses 360° cameras and intelligent radar to enhance site safety. Meanwhile, CareTrack telematics and ActiveCare 24/7 provide real-time machine health data and predictive maintenance alerts which keeps fleets productive and protected.
Control is designed to be smoother and more intuitive with a precision joystick system and ergonomic switch layout, with customisable settings to suit operator preferences. New features include electric travel pedals and a tiltable left console to make it easier to get into and out of the cab.
