Thwaites is launching an all-new, all electric 3-tonne dumper. The machine has been designed with contractors and hirers in mind. The 3-tonne electric machine that was displayed at BAUMA, will be an advanced concept machine, with the go to market version being available in 2023.
Thwaites General Sales Manager, Andy Sabin said, “As the demand for cleaner alternative fuel sources grows, we are keen to ensure we offer a quality product that delivers for our customers, their clients and the environment”.
Similar Unladen Weight as Diesel Dumper
Four maintenance free, long-life, lithium-ion (dry-cell) batteries, operating at 48V, are fitted. Each battery is rated at 5.75kWh, providing the power to drive the machine. With two highly efficient electric motors (one for traction, one for the hydraulic services) giving the operator the control and manoeuvrability expected from a Thwaites dumper.
The electric drive dumper has a similar unladen weight when compared to the diesel/hydrostatic version. The main battery pack and driveline components, now sit low in the rear chassis, lowering the centre of gravity when compared to the hydrostatic drive machine, further improving machine stability.
Critically, the battery pack will complete a full 8-hour shift of `normal site operation’ from a single charge.
The standard on-board 3.4kW battery charger can charge the pack from 0-100% in 8hrs. Optional off-board chargers rated at 7kW (single-phase) and 22kW (three-phase) have charge times of 4hrs and 2hrs respectively.
Andy Sabin concluded “We are delighted to be able to offer this all electric 3-tonne dumper for consideration at this year’s BAUMA event. Available for both the UK and export market, the machine will provide for the rental market, a cleaner, quieter, alternative, giving contractors options to use the machine in more urban refurbishment settings. In addition, the new, all electric dumper is compliant with the growing number of authorities and bodies that operate low emission zones”.
