Unfortunately there is very little.
Mark Chisholm and co. put out a video about five years ago that was helpful, but centered on a stanard that is now outdated. The video may still be available. Contact Mark to find out.
Go to the 'Articles' section of this website and look at the article "Crane Best Practices in Tree Removal".
This is the link:
http://www.treebuzz.com/pdf/mar07-cb.pdf
The main topic of the article is tieing-in to the crane, but there is also a discussion of ANSI and OSHA at the beginning, and other references listed at the end.
If you have time you could wade through some of the discussions in this forum (Crane Use) and find discussions on various things.

In another post you had asked about electrical safety. Contact TCIA (800-733-2622) and ask about their EHAP (Electrical Hazards Awareness Program).
If you are interested in travellng contact me via email or PM. I am doing two, one day crane workshops in September in Louisiana.
Hope this helps.
