Abstract
Disclosed are various embodiments for stabilizing a hoisted object. A hoisted object such as a litter can have a tendency spin while being retrieved on a lift line. A device may be connected to the hoisted object to reduce a spin or other angular velocity of the hoisted object. The device may monitor stability of the hoisted object and determine that the hoisted object is unstable. The device may be configured to rotate at least one flywheel to apply torque to an enclosure of the device.
