# Swivel device for connecting human and/or non-human cargo to a rotorcraft

## Abstract

A swivel device that is configured for connecting human and/or non-human cargo to a rotorcraft, comprising: a first mechanical coupling device that is configured for being connected to the rotorcraft; a second mechanical coupling device that is configured for being connected to the human and/or non-human cargo; and a swivel arrangement that couples the first mechanical coupling device with the second mechanical coupling device, wherein the swivel arrangement provides for a primary load path that is configured for load transfer between the second mechanical coupling device and the first mechanical coupling device in a normal operation mode, and a secondary redundant load path that is configured for load transfer between the second mechanical coupling device and the first mechanical coupling device in an emergency operation mode.
