COMPACT EXCAVATORS

Featuring a 3,5-hour battery capacity, the Bobcat E19e comes with a super-fast charger, which allows for opportunity charging during work breaks, thus maximising uptime on site.

Leading the way

For e-solutions to be successful in construction equipment, the load cycles and tasks of the machines are a key factor. That is why compact excavators are leading the way in the electrification revolution, as demonstrated by an array of recent commercial and prototype introductions, writes Munesu Shoko .

A quiet revolution is taking place. Traditional original equipment manufacturers (OEMs) have laid out the field of new energy con struction machinery – electric. As well as being better for the environment, electric construction gear is also opening up opportunities for

new ways of working, allowing environments beyond traditional construction sites to get the job done with less noise, fewer vibrations and no exhaust fumes. However, the pace of the electric revolution remains apparent on the smaller end of the construction equipment scale. “I still see electric drives in rather

smaller power ranges of up to a maximum of 20 kW,” says Dr Marcus Geimer, head of the Mobile Machinery section of the Karlsruhe Institute of Technology. “For electric solutions to be successful, the load cycles and the tasks of the machines count.” The energy requirement – battery size – for a full day’s shift is easier and more cost-effective to package on a smaller machine, which is why electrification is gaining pace in compact excavators.

“Our prototype mini excavator is an example of Yanmar’s system integrator applications technology, integrating power and control systems with advanced applications management in a versatile and easy to use machine.”
