Main Causes of Permanent Lifting Magnets Damage

An Armstrong NL-B permanent lifting magnet could be used for many years when you strictly follow the Instruction Manual shipped along with the magnetic lifting device.

You may want to know which factors could cause permanent lifting magnets to be out of order.

The biggest cause of lifting magnet damage is collision against other heavy objects.

  • Collisions could damage safety latch eventhough NL-B lifting magnet has the level part of its L shaped safety latch lowered into a slot in order to protect it against collisions. However, the safety latch could survive in light collisions after we changed our design and started to mill the protection slot at the top of NL-B lifting magnets started a few yeas ago. If there is no the slot to protect the safety latch, such as competiting manufacturers’ permanent lifting magnets, it could be more easily damaged from collisions.
  • Besides the safety latch, handle could also be damaged from a collision. Armstrong NL-B permanent lifting magnets are installed with solid handles which are very sturdy and would not deformed in moderate intensity impact. In the market of permanent lifting magnets, some handles are composed of a tube and a sliding bar inside. This kind of the handle could be more easily deformed and out of order in collisions due to the tube construction.
  • If collisions or scratches occur at the bottom of the permanent lifting magnets, there would be dents or burrs at this area. These dents or burrs could lead to air gaps and reduce their rated lifting capacity. You must inspect the bottom surface conditions after they are hit by any heavy or sharp objects.
In addition to collisions, moisture and high temperature over 148°F are also critical causes of permanent lifting magnet damages which may be permanent.
