The compact power units are small, lightweight and offer maximum power in the most confined space. They remain fully functional even on extreme slopes (up to 30 degrees). The battery-powered units have connection ports for two rechargeable batteries so they can run for up to 10 hours in ECO mode. All rescue equipment from WEBER RESCUE SYSTEMS (even large rescue rams) can be operated with these power unites. A number of the compact power units are equipped with the ECO function, which means that automatic speed regulation ensures low-noise and economical operation.
