The permanent magnet lifter is widely used in shipbuilding, engineering machinery, mold manufacturing and other industries. What should we pay attention to when choosing a permanent lifting magnet?

The permanent magnet lifter is mainly used to hold plate-like or cylindrical ferromagnetic materials in the lifting process. It has light structure, easy to use, strong holding force, no power consumption, which helps improve the working conditions of loading and unloading operations. It is widely used in shipbuilding, engineering machinery, mold manufacturing and other industries. What should we pay attention to when choosing a permanent lifting magnet?
 
First, the safety locking device, if the safety locking device is not designed properly, it will lose and effect lifting process, the suction object may fall and cause an accident.

Second, the internal magnetic circuit structure, which directly affects whether the pull-out force of the permanent magnet jack can be exerted.

Third, the flexibility of the spindle rotation is directly related to the comfort of the operation process, but it is very difficult to be inflexible.
Fourth, the safety factor is the most important issue when purchasing a permanent lifting magnet. Its safety factors are generally 2.5, 3.0, and 3.5. The larger the safety factor, the more safety.

Fifth, the treatment of the suction surface, the suction surface must be finely ground, so that it can be sucked to the maximum extent during lifting.
Six. Lifting ring is generally welded, which is prone to problems after prolonged use and requires frequent attention.
