[0003] MBB 120/83/V MILANQ-P.za Castelio n, 2 Description of the utility model entitled: "Clamping device for external aerial loads" of the company MESSERSCHMITT-BOLKOW BLOHM GMBH with registered office.

[0004] in Monaco (Rep.

[0005] Fed.

[0006] of Germany) filed on 27.Arh.:383 216638/83 The innovation concerns a device for clamping external loads on aircraft.

[0007] Devices of the kind mentioned.

[0008] are known and are used to prevent the external loads from moving freely relative to the aircraft during flight, otherwise considerable damage to the suspension device, the external load, etc. may occur.

[0009] no and to the plane.

[0010] In general, external loads are suspended from the aircraft by means of a suspension device, equipped consecutively with several hooks or eyes in the direction of flight, and to avoid said own movements they are fixed against the aircraft with the aid of clamps.

[0011] Patent DE PS 29 38 O60 concerns, for example, a clamping device, the jaws of which for hooking and clamping purposes can be oriented against the external load by means of a toothed transmission and are adaptable to different JAUANN PATENT STUDY by Jaumann P.

[0056] After having hooked up the external load, the support 6 is moved in the direction of extraction 12 on the external load (not shown) by means of the pinion 2 until it is firmly fixed. The ratchet 4, which blocks in the return direction, stops the support 6 under the pressure of the spring 5, until.
