ABSTRACT:
A device for suspending and wedging loads under aircraft ensures, through a central control, the wedging of a load carried under an aircraft at a level determined by a pair of suspension hooks subjected to balanced stresses. The central control is obtained by sleeves which slide vertically under the action of rotary shafts and bevel-tooth gears, the vertical translation of these sleeves ensuring the downward movement of parts of bearings engaging the load.
