Pivoting Or Vertical Lifting Of Loads - ALFRA TML 90R Manual De Istrucciones

Pivoting or vertical lifting of loads

The special design of the TML 90
load can be turned around at 360° and pivoted at up to 90°.
1. Be sure to use a flexible soft eye to avoid jamming the lifting magnet into the hook of the crane. Otherwise this
leads to extremely unfavorable load conditions and the lifting capacity would no longer be assured. In addition, you
protect your magnet from damage and extend his lifetime by using a soft eye.
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 load and 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 the 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.
