New Mecalac e12: The first 100%-electric machine

June 12, 2019

The Mecalac e12 means less vibration, less noise pollution, less maintenance, less risk of on-site accidents and absolutely no CO2 or particulate emissions.

Mecalac offers the first 100%-electric machine, which meets the three key requirements for the urban job sites of today and tomorrow: autonomy, performance and 360° compactness. It’s a technological response inspired by the constantly evolving people, terrain and constraints of urban construction sites.

With the e12, Mecalac is entering a new chapter of its history, by making available an electric excavator. This landmark is being recognized by the range being the first to be allocated the letter “e”: “e” for electric, “e” for ecosystem, “e” for emits nothing and “e” for emblematic.


For a long time now, we at Mecalac have been considering the environment and sustainable development as an investment and a key stake for the future, even in the field of internal combustion engines. The group’s R&D policy focusses on designing engines with the smallest possible environmental impact, both on job sites and on local residents.

The e12 is the logical conclusion of an approach started in 1974: optimize job sites with ever-more versatile machines, reduce the number of engines on site, and make them profitable to run.


The electric version of the 12MTX fits perfectly within Mecalac’s philosophy of moving towards urban building sites that are ever-more compact, high-performance and environmentally friendly. The architecture of the internal combustion version of the 12 MTX makes it the natural forerunner of the electric version the housing for an internal combustion engine now incorporates LiFePO4 battery technology — iron and phosphate for three times as many charge cycles — that marry a service life considerably better than classic batteries with complete safety: no risk of fires and no risk of battery fluid leaks.


With a structure designed for the city from the outset and two independently running electric motors, one powering the excavation mechanism and one for movement, the Mecalac e12 is destined to become a fixture in plant fleets for urban settings. Apart from its performance and range, its 100% electric transmission offers unrivalled tractive force as soon as the engine is started, with brake energy regeneration. The electric motors’ incredible power density make it possible to keep it extremely compact; they also require no maintenance. Moreover, the e12 has a charging station that can be used to recharge it on site in six to seven hours. Thus without compromising on power, the e12 can work all day without needing to recharge the batteries: a range of eight hours at the highest power output.

The Mecalac e12 means less vibration, less noise pollution, less maintenance (no more filters, no more oil, etc.), less risk of on-site accidents, less spent on maintenance, and absolutely no CO2 or particulate emissions.

The e12 works all day, racking up more time in action than it does standing around every day. Its articulated chassis means it can move easily around any site, and this agility also plays a role in its overall performance. With diesels to be banned in major conurbations already announced and fixed, and with increasingly dense urban development and the cramped spaces that go hand-in-hand with that, the new Mecalac e12’s perfect blend of architecture and technology is paving the way for safer, cleaner and more efficient urban building sites.

“Any electric engine must meet to three major challenges: range, performance and compactness. The Mecalac e12 is the first 100%-electric excavator that does not compromise on any of those three criteria. The key to our machine’s range and performance is in its very architecture. The power source — which is separate from the upper structure — means we can install a record capacity of 146kWh, which results in an unrivalled range of 8 hours”, Patrick Brehmer, Head of marketing Product Management & Design.
