  • Patent number: 4923135
    Abstract: 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.

  • Patent number: 4855539
    Abstract: A stowing device for a cable feed, particularly for the connecting cable of a central aircraft supply system at airports. The device has a cable fixed point at a passenger gate. The device comprises a double cable drum having a service drum for a service cable and a coaxial equalization drum for an equalization cable, and a drive for both directions of rotation of the drum. A saving in the total length of the connecting cable is obtained as translation movement is superimposed upon the rotation of the double cable drum. The double cable drum is displaced in a longitudinal guide over a distance equal to the length of the equalization cable which has been freed or wound up while the service cable is unwound or wound up, respectively. Alternately, the cable drum is supported on and translated with the moveable section of a guide rail.
