摘要
External winch (1) for a helicopter with stabilizing devices for stabilizing an external load (23) attached to the side of a helicopter cell (6) of the helicopter (35) via a load cable (10) of the external winch (1) running off a cable drum (11), the Stabilization devices - detection devices (29) for detecting movements of the external load (23) and damping devices (32) which dampen oscillating movements of the external load (23) by active engagement depending on the detected movements of the external load (23), - the damping devices (32) a cable outlet (12) which guides the load cable (10) running down from the cable drum (11) and which, opposite the helicopter cell (6), about a first pivot axis (15) extending horizontally at a distance above the cable outlet (12) and around a second pivot axis (18) running at a distance from the cable outlet (12) transversely to the first pivot axis (15) is pivotably mounted for active damping of the P Ending movements of the external load (23) depending on the detected movements of the external load (23) about the first pivot axis (15) and about the second pivot axis (18) actively pivot with respect to the helicopter cell (6), characterized in that the cable drum (11) and the base (16) of the external winch (1) comprising the cable outlet (12) is pivotable about the first pivot axis (15) and the second pivot axis (18), the base (16) about the first and the second pivot axis (15, 18) ) is pivotably mounted on a winch arm (2) which can be pivoted out about a vertical third pivot axis (7).
