From The Crosby Group:
For more than a decade, the Crosby Users Guide for Lifting has been one of the most requested printed reference guides for the lifting industry, with over a half million in circulation. This new electronic version takes the information available on the printed version to a new level. The Crosby Users Guide for Lifting-Free version contains all the great features of the printed version including: references to various B30 standards concerning inspection/rejection criteria for slings and hardware, rigging terminology, guidelines for developing a sound rigging plan, wire rope and chain capacity charts, sling loading information, working with center of gravity and product information on selected Crosby hardware. Upgrading to the Plus version will provide you with many interactive tools to help meet your day to day needs. The result is a reference guide you will not want to be without.
