Chains come in various strengths depending on intended usage. Grade 70 chains for example are typically used in towing applications. Grade 80 or better are the only chains rated for overhead lifting. Some say that since Grade 70 chains are used by tow operators to pull and load vehicles onto a flatbed tow truck than rescuers can use them. Others say that you need a chain that is rated for overhead lifting. Firehouse Expo HOT instructor Billy Leach, recommends that only Grade 80 or better should be used for extrication.
