Sling load release


I am wondering if anyone knows of an “emergency release” (under load) of a sling load that can be controlled by, for example, a servo? I intend to do some lifting with a sling of around 10-17 m chain and if anything would happen to the load I would like to be able to drop it to not risk the aircraft.

Thankful for any help, I’ve been googling around but can’t seem to find what we need.
