PIVOTING OR VERTICAL LIFTING OF LOADS
The special design of the TML500 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-bearingcapacity 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 of the load-figure that corresponds to the direction.
