Recovery - The Fundamentals

[the evil twin]

Thanks mate

Is there ever a case where you multiple or increase the load on equipment by hooking up redirects/double/triple line pulls? Or for the most part it halves, and stays the same as original on things like pulleys and anchor point the pulley is connected to?

Halving loads etc only works in a perfect world.
Real world use means snatch blocks, pulleys etc introduce their own loads IE depending on dia, cable type etc it may be that you only get a, say, 45% reduction instead of the full 50.
That is no biggee unless you are up on the ragged edge.

The other thing to be aware of is Sling Load Angle on bridles, very common, or if loading a redirect which is quite unusal but may be handy if recovering or winching around a curved path
