Assembling - pewag PMA Serie Traducción Del Manual De Instrucciones

Following four factors reduce the working load limit of lifting magnets.
Air gap
Air gap is the space between the polar surface and the material of the load. Air gaps are caused by dirt, oxidation,
painting, bumps, by anything that hinders the perfect, flat and clean contact between the polar surface and the
metal of the load. Also the length of the load might cause air gap due to its flexion. The polar surfaces might lose
some contact with the load.
Permanent magnetic lifters from pewag can grab the load even when there are air gaps. In these cases the working
load limit must be reduced as shown on page 5. Alternatively for long loads a device using more magnets may
avoid air gap.
Load thickness
When the thickness of the load does not reach the indicated minimum thickness on the pewag winner profimag
lifting magnet plate and on page 4 the full working load limit can't be granted. In this case the working load limit
must also be reduced as shown on page 5.
Material type
Magnetism force depends on different material typology. Maximum magnetism is reached when grabbing mild steel.
For those metals which are different from mild steel a factor must be applied to the working load limit as follows:
Mild steel
Alloy steel
C 40 steel
Cast iron
For example:
Rated working load limit
Cast iron 300 kg x 0.45 =
Contact surface
Maximum performance of pewag winner profimag lifting magnets is reached when the polar surface is totally and
smoothly in contact with the material of the load.
If the contact surface of the load has for example holes, the lifting magnet cannot apply its full magnetic force to the
load. It means the working load limit is going to be reduced.

5. Assembling

Before getting started
pewag winner profimag lifting magnet is
delivered in carton packing, wrapped in a layer
of foamed polyurethane to grant functionality
and protection.
1) Take out the lifter, the lever, the hex key (allen
key) and the screw to fix the lever with the
body.
2) Insert the lever in the small hub, from the free
side.
3) Fix the lever correctly by tightening the screw
in the hub and the notch of the lever.
4) Do not change or modify anything on the
pewag winner profimag lifting magnet
without permission of pewag.
