Next-Generation Fully-Electric Excavator

Battery powered

Regeneration of energy

High overall efficiency

Low emissions

Robotic operation

Innovative volume-neutral cylinder technology

Elcavator AS has developed an innovative energy-efficient “power/force transmission system” with possibility for regeneration of energy and an efficiency of up to 90%. This will cut CO2-emissions and operation costs of excavation operations significantly.


The highly efficient technology on the Elcavator™ consist of well proven electro drives combined with patented volume neutral cylinders. The force transmission and speed control are done with electronics/electromotors, without any powerconsuming hydraulic valves. One electromotor/pump on each hydraulic circuit/cylinder enables very accurate power management with possibility for re-generation of power during lowering of loads. 


This thecnology makes it possible to use the Elcavator™ an entire working day without need of charging the battery.


The system is also prepared for including a hydrogen fuel cell. By adding this the Elcavator™ does not need battery-charging on site, only re-filling of hydrogen.
