Specifications Overview
The PL-550 Magnetic Plate Lifter is designed for lifting flat loads with varying thicknesses. The rated lifting capacity is 550 lb, but this capacity decreases with the thickness of the load and the air gap. For example, at a 0.5" thickness, the capacity is 450 lb, and at 0.1", it is 75 lb. The air gap also affects the lifting capacity, with a 1/32" gap reducing the capacity to 13% of the rated value.

Critical Parameters
The lifter's performance is highly dependent on the thickness of the load and the air gap. Users must ensure these parameters are within specified limits to maintain safety and efficiency.
