Power supply system for an aircraft service pit

An electrical power supply system for an underground service pit, comprising:

• an electrical supply cable configured to electrically connect to an electrical power supply at a first end and an external power socket of an aircraft at a second end so that electrical power can be supplied to the aircraft;
• a storage chamber disposed within the underground service pit configured to stow the electrical supply cable;
• a cable access point configured to allow access to the second end of the cable;
• a device for unstowing the electrical supply cable from the storage chamber;
• a cable guiding wheel of the device, the cable guiding wheel disposed at ground level above the underground service pit and configured to receive the cable;
• and
• a motor of the device, the motor coupled to the cable guiding wheel and configured to drive the cable guiding wheel,
• wherein, upon activation, the motor rotates the cable guiding wheel to generate a pulling force on the cable to at least partially lift the cable out of the storage chamber, and
• wherein the device is mounted to the cable access point.
