LIFTING GUIDELINES
(ROUND BARS)
Values shown are for maximum rated capacities when operating instructions and warnings are followed.
VALUES ARE BASED UPON AISI 1020 STEEL
Higher alloy steels and other magnetic materials will require further reductions of these rated capacities
(See page 11 for the Guidelines for the reduction of the Rated Lifting Capacities.)
