An electrically-driven container straddle carrier, terminal tractor or equivalent free-travel device that runs on rubber tires and handles containers. The device includes a repeatedly-chargeable electric power storage and an automatic charging system connected to the power storage, which is arranged to couple to an external source of electric power for a part of the work cycle of the device handling containers for charging the electric power storage without disturbing the normal work cycle of the device. When the device is a transport straddle carrier that operates in a cargo terminal between a crane and a container interchange area, the automatic charging system includes a power supply station arranged in the terminal area, provided with a power supply head, whereby the container straddle carrier includes a charging head connected to the power storage and coupling to the power supply station.
