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.

A prototype of Thwaites' first electric site dumper.

It is powered by four lithium-ion (dry-cell) batteries, operating at 48V. Each battery is rated at 5.75kWh, driving one motor for traction and another for hydraulic tipping.

The electric drive 3-tonne dumper has a similar unladen weight to the diesel/hydrostatic version but with the main battery pack and driveline components now sitting lower in the rear chassis, it has a lower centre of gravity and thus better stability.

The standard on-board 3.4kW battery charger can charge the pack from 0-100% in eight hours. Optional off-board chargers rated at 7kW (single-phase) and 22kW (three-phase) have charge times of four hours and two hours respectively.
