The Crosby User’s Guide for Heavy Lifts - Free contains all the great features of the printed version, and takes the information to a whole new level with informative slides from Crosby's World Class Heavy Lift Training seminars, and product information on selected Crosby hardware designed for heavy lifts.

The Free version has in-app purchases enabled, allowing you to obtain access to the results of interactive calculators.

If the calculators are purchased, you'll have the ability to save the results of each interactive calculator to a "Scratch Pad." All calculations saved in the "Scratch Pad" can be exported as a PDF email attachment, letting you send the results to a colleague or to yourself for reference.

To help meet your day to day needs, we have added many interactive tools to this version. The result is a reference guide you will not want to be without.
