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.)
NEVER LIFT ANY LOADS WITH ANY DIMENSION GREATER THAN 60
INCHES (1.5 METERS)
OR WITH A THICKNESS LESS THAN 1/4” (6.4 mm)
† Air Gap = nonmagnetic separation between magnet’s lifting surface and load.
* Lifting capacity affected by peel and thickness. See notes 2 & 4 in the “Important
Facts” and “Recommended Lifting Procedures” (See pages 6, 7 and 10).
