FIELD: transport. ^ SUBSTANCE: proposed device comprises outer suspension and cargo orientation system. The outer suspension incorporates crosspiece with hauling cables furnished with cargo grippers. The crosspiece is coupled, via two converging links, with flight vehicle lock. The cargo orientation system incorporates two drives mounted on fuselage. Every drive is connected, via flexible link and deflecting block, with one end of the said crosspiece. To compensate for flexible link length variation in flight, the orientation system additionally comprises, for aforesaid every drive, lever pivoted to the fuselage. The said lever accommodates additional deflecting unit fitted on one end of the lever and enveloped by the flexible link and is coupled with spring-loaded appliance arranged on the fuselage. The axle of one of the said deflecting units on every lever can be aligned with the lever axis of rotation. The other deflecting is fixed on the lever free end. Note that both levers can be spring-loaded by means of single acting power cylinders, or by torsions. ^ EFFECT: increased range of helicopter operation in civil and erection works, higher safety and easier crew operation. ^ 4 cl, 2 dwg |
