Based on Hyundai's Robex series, the 18E is powered by a 20.7-kWh lithium-ion battery pack paired with a 13-kW (27-kW peak) electric motor.

Recharging time is just over five hours when using a 220V supply.

The excavator’s operating weight is 1,863 kg (4,107 lb) with a canopy, or 2,030 kg (4,475 lb) for the machines with a full cab. Bucket breakout force is rated at 15.1 kN with a 0.04-m3 bucket. Dipper arm tearout force is rated at 9.4 kN. It is equipped with an 1,800-mm (5.9-ft) monoboom and a 960-mm (3.1-ft) dipper arm. The maximum digging depth is 2,405 mm (7.8 ft) and the machine has a digging reach of 4,110 mm (13.4 ft).

The two tonne electric mini-excavator. The DX20ZE is driven by a powerful, in-house developed 20 kWh Lithium ion battery pack. A quick-charger system restores 80% of the battery power after only one hour of charging, whilst the on-board charger restores the maximum charge after six hours of charging.

Liebherr's first crawler excavator powered by a hydrogen combustion engine.

The 50-ton R9XX H₂ prototype is powered by the hydrogen H966 engine which is based on an intake manifold injection technology. The R9XX H₂ excavator and the refueling station communicate via infrared sensor for fast and safe refueling using a standardized high-speed protocol.
