The Rigger's Bible
The Rigger's Bible is a general reference guide for riggers and crane operators.
Although it was written with the construction industry in mind, the concepts and data it discusses are still pertinent to the tree service industry because of the similarity between the applications. Both tree and construction riggers commonly employ the use of cranes, mechanical advantage, and similar working loads in their rigging systems. Because the principles of physics it discusses are universal, this book is an excellent resource for anybody who does heavy rigging.
