Abstract
This device with independent hooks and automatic locking mechanism for hooking loads suspended under aircraft comprises an effort scaling-down device associated with each hook, mechanisms for coupling the two scaling-down mechanisms with each other, and the detent-positioning of this coupling mechanism through the medium of a third common scaling-down device. Thus, the preliminary manual cocking, i.e. the detent-positioning of the coupling, provides at the same time the simultaneous resetting of the first pair of effort scaling-down mechanisms associated therewith, so that the suspension hooks are free with respect to the retaining mechanism and can pivot to their closed position independently of each other under the action of the load suspension rings when the load is fixed in position, the third scaling-down device further assisting in reducing the efforts exerted on the common retaining pawl, the raising of this common pawl being necessarily attended by the simultaneous opening of the hook.
