Permitted by Armstrong Magnetics Inc, Innov Magnetics Ltd manufactures NL-B Series Permanent Lifting Magnets with the brand of Armstrong LiftMag™

Features:
  Safer than normal lifting magnets by pretesting lifting safety.
 In some complicated situations it is difficult to estimate the actual lifting value with enough safety coefficient and consequently you are not sure if the lifting operation is safe or not, then you can take the following steps to get a safer lifting operation.
 1. Place the lifting magnet at the load.
 2. Turn the handle counterclockwise to the vertical position.
 3. Insert the tip of the screw driver shipped with the lifting magnet into a small hole at the yellow cover to hold the handle in the position.
 4. Lift the lifting magnet and the load 2”-3” from the floor.
 5. If the load can be lifted, place the load back onto the floor.
 6. Take off the screw driver and turn the handle to ON position. The handle is locked by the slide pin.
 7. Lift the load again. This time the safety coefficient is 2 at least.
  Thicker front Aluminum cover to protect rotor shaft head
  Main body Nickel plated.
