Lightweight Selecto® continuous-duty electro lifting magnets are available from Eriez®. They can be used individually or in multiples to eliminate the need for hooks, slings, and grabs.
The magnets are rated at 100 percent duty cycle for continuous operation. A variety of models are available to handle loads from 375 to 12,125 lbs.
The SL series requires a compact variable-voltage rectifier controller or a fixed-voltage rectifier to furnish the desired DC power from any AC source. ST series units have a miniaturized rectifier/drop control circuit with a lift-off-drop switch attached to the magnet that can cancel briefly any residual magnetism to allow the load to be discharged.
