Pivoting Or Vertical Lifting Of Loads - ALFRA TML 400R Mode D'emploi

Pivoting or Vertical Lifting of Loads

The special design of the TML 400R lifting magnet allows the user to turn and pivot the load freely. The suspended
load can be turned around at 360° and pivoted at 90° in most cases.
1. Be sure to use a flexible soft eye to avoid jamming the lifting magnet into the hook of the crane since this would
lead to extremely unfavorable load conditions and the lifting capacity would no longer be assured. In addition,
this will protect your magnet from damage and extend its lifetime.
2. If the load is attached horizontally to the magnet, the entire breakaway force of the lifting magnet is acting on
the load, so you can use 100 % of the lifting capacity as stated in table 2. However, if the load and the magnet
surface tilt at an angle other than 0° to horizontal, the load-bearing capacity decreases due to the new alignment of
the magnet to the gravity of Earth. As soon as the load is suspended vertically, i.e. at an angle of 90°, friction will
be the only effect exerted by the magnet which is not more than 10-35 % of the maximum load-bearing capacity,
depending on material being lifted.
You can calculate the maximum load-bearing capacity of your magnet, including the 3:1 safety factor, on the basis
