MECALAC e12: a 100%-electric excavator

MECALAC e12: a 100%-electric excavator

→ Winner of the “Energy Transition” Prize at the Intermat 2018 Innovation Awards.

The world’s first compact wheeled excavator running only on electricity, without compromising on battery life, performance and compactness.

The electric version of the 12 MTX 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, so the emplacement for an internal combustion engine now houses LiFePO4 battery technology – lithium iron phosphate for three times as many charge cycles – that combine a service life, comfortably better than classic batteries, with complete safety: no risk of fires and no risk of battery fluid leaks. 

Any electric engine must rise 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 146kW.h, which results in an unrivalled range of 8h”, explains Patrick Brehmer, Head of Design and Product Management.
