The invention relates to a heavy-duty ground transportation vehicle, in particular an unmanned guided heavy-duty transportation vehicle for ISO containers, which is environmentally friendly. This is achieved by arranging a battery in the heavy-duty transportation vehicle to supply power to a travelling drive of the vehicle. The battery is typically a lead battery of considerable weight, and is releasably connected to the transport vehicle in a manner that permits changing the battery (e.g., exchanging a depleted battery for a fresh battery) and recharging the depleted battery at a location outside the vehicle. The battery can be moved into and out of transport vehicle transversely with respect to a longitudinal direction of the vehicle.
