1. A fixture comprising:
a surface;
a cylindrical wall extending from the surface; wherein the cylindrical wall is configured to receive at least a portion of a bell mouth of a rescue hoist;
a body portion extending from the surface and disposed within the cylindrical wall;
a proximity sensor configured to detect a distance to a hook assembly of the rescue hoist and generate a signal indicative of the distance;
an electromagnet; and
a processor,
wherein the surface and the body portion define a through hole; wherein a cable of the rescue hoist is configured to extend through the through hole when the fixture is coupled to the bell mouth; wherein the body portion abuts the bell mouth when the fixture is coupled to the bell mouth, and
wherein the processor is configured to receive the signal indicative of the distance; wherein the processor is configured to detect when the hook assembly abuts the surface based on the signal indicative of the distance; wherein the processor is configured to engage the electromagnet in response to detecting the hook assembly abuts the surface.
