Ive seen and even argued about the dangers of extreme rigging angles with many people out in the bush. I have spent ten years now learning the trade. Still have lots to learn. Thought i would post up some links and start a thread just about general winch/sling myths facts questions what have you. One i see alot guys changing the angle of a winchline with a snatch block and expecting it to be the same stress as a straight pull. Here is oneink to get started. The forces go up alot faster than some would think when snatchblocks start being added.

This military hand book is great for basic stuff. Have a read, it's pretty nuts what you can do with some hand tools a few Marines. Goes over some basic principles, safety, then into nitty gritty techniques.
Pretty dry stuff , but a shit load of info
If you ever run into a stuck tank this will help also.

one of the biggest things I have seen people do is winching with the line dragging over rocks wrecks a cable in a real hurry

Not just the freying of the cable but the side loading of it. When i was in school we had a load cell we could put in at different parts of the rigging and see how much force was pulling. Really blew my mind.

Most of the marines I have met can't even tie their own shoe.

none of those angles are OK in the link.

if from a gantry crane, it will fuck up your Sheeves. boom cranes can't take those angles at all. and if you invert it and put the OK, or worse on a container, you stand the chance of buckling your container (if loaded to teh max).

Not that i know everything, but i've been doing rigging since i was a child in the woods.

Its a good start though!

Thats why they get told what to do, and the obvious simpleness of the manuals :D

I thik your missing the point. It was showing what the actual stress would be in tye rigging with the angles compared to a straight basket. And i know you know everything your from murica. Your all smarter than us.

I do boilerhouse rigging. Large components tight areas. When your limited on space and tighten up your rigging its important to know that the 100,000 pounds your moving can have a combined line pull exponentialy more.

I am by no means a rigger, but l have spent my share of time looking at Free Body Diagrams and calculating tension on cables with vector analysis, its rather easy to get a good idea of what you have once you understand scalar quantities and vector analysis.

I always had a fair understanding of the stresses and loads, after operating hiab it now kinda burned into my brain now .

then honk and laugh!
