The graphic used to illustrate information are not intended to be exact representations, but rather are added to help the reader's understanding. Operators, riggers, signal persons, and supervisors all need to be fully aware of conditions that can cause a crane to come into an unsafe condition. Along with other field guides in Crane Institute of America's Safe Craning series (see last page for full details), Load Charts is designed to be used to improve the operating skills and heighten safety awareness of all those that work with, and around, cranes. Supervisors, in particular, may find this series of field guides useful in pre-shift "toolbox" safety talks. The capacity charts used in this book do not represent any particular crane manufacture and are used for illustration purposes only. Do not use these capacity charts when lifting actual loads..
