This device for locking on fixed support loads carried under aircraft comprises, between the suspension rings or saddles of the load and the fixed structure of the aircraft, a pair of spaced pivot pins having fulcrumed thereon a pair of symmetrically opposed bell-crank levers having in turn one arm pivotally connected to a suspension hook and the other arm pivotally connected to a common stretching device, the fulcri of the levers having each also pivoted thereto a radial link having its free end pivoted to a pair of links connected the one to a central rocker and the other to the relevant hook, the rocker being responsive to a detent-positioning device. Due to the provision of adequate extensions of the stretching device and of the hooks, completed by another pair of links, another pair of hooks disposed externally and in coplanar relationship to the first pair may be provided for accommodating indifferently loads having either suspension rings or saddles disposed at one standard distance between centers or other suspension rings or saddles disposed at another standard distance between centers. |
