A stowing apparatus for the connection cable of an airport central system for power supply to aircraft is constructed in the form of a double drum (22), said drum comprises a takeup or coiling drum (28) for the length of the connection cable to be run out and a compensating drum (26) coaxial therewith from which the cable is led to a fixed connection of the bridge head of the gate. On the compensating drum (26) a compensating length of the cable is loosely wound in such a manner that the spiral of the compensating length on rotation of the drum and uncoiling and coiling of the connection cable moves radially from the outside to the inside and from the inside to the outside respectively, radially extending support bearings (44) being provided to reduce friction. In this manner the necessary revolutions of the coiling drum (28) are compensated by the spiral of the cable compensation portion. The drive of the double drum is by an electric motor (76) and transmission gearing (78 and 82) in such a manner that a drum speed of about 6 rpm results.
