Volvo launches Dig Assist in North America, an intuitive machine control solution for crawler excavators

Volvo Dig Assist unlocks the full potential of an excavator’s productivity. Utilizing Volvo Co-Pilot — the award-winning in-cab interface with 10-inch high-resolution touch screen — Dig Assist allows operators to easily input job specifications and track progress along the way to ensure the job is done right the first time, every time.

“We’ve designed Dig Assist in a way that is very easy to learn and very intuitive to use — requiring as little as 10 minutes of upfront training and only a few touches to get started with a new job,” said Matt McLean, product manager, GPE products at Volvo Construction Equipment. “Once you’re up and running, there’s no more guesswork. You can design and track progress in real time — thereby reducing the need for on-site engineers, surveyors, and manual grade and depth checks. It’s very simple to use, but can make an enormous impact to productivity and job profitability.”

With Doka Framax Xlife stripping corner all retracting or expanding formwork can be done by one worker

Doka’s Framax Xlife stripping corner has successfully been used in forming cores/shafts on thousands of projects around the globe. With a simple built-in ratchet design, all the work of retracting or expanding formwork can be done by one worker at the top of the core. The built-in ratchet makes the operation safe and fast. In accordance with accident prevention guidelines, no crane is required for expanding to set or contracting to strip the core forms. The formwork unit can then be repositioned in a single lift to save crane time
