OPERATING INSTRUCTIONS
for permanent magnetic lifting magnet
WORKHOLDING AND AUTOMATION
3. Usage:
a) Before putting in operation:
Upon receipt of the shipment, check whether load lifting magnet has been delivered undamaged
and complete. Contact your supplier immediately in case you notice the magnet is damaged
and / or incomplete.
Scope of delivery:
- Magnet 531.01-150, 531.01-300, 531.01-600, 531.01-1200, or 531.01-2000
- Type plate and instruction plate fixed to the magnet
- Test certificate
- Operating instructions including CE declaration of conformity
b) Ascertain work load limits (WLL):
Since the nominal lifting capacities are to a great extent depending on the workpiece properties,
the holding force must be assessed before each use.
Please bear in mind that the lifting capacity is affected by:
-
Air gap
between magnet and workpiece because of dirt, paper, burrs, damages, paint, etc.
-
Material thickness
of
load.
See performance graphs on page 18.
The thinner the load, the lower the lift capacity.
-
Length and width
of
load.
The lift capacity depends on the size of the steel plate. Minimum size according to 1st
column under max. lifting capacity in the table. For smaller plates the lifting capacity is
reduced according to the 2nd column. Large steel sheets will sag and want to peel
off the magnet. This peel-off effect reduces the loadbearing capacity and limits the
maximum sheet size that can be lifted.
These effects are compiled in the table on page 17.
-
Material type
of
load.
Load lifting magnets are intended for transporting ferromagnetic flat materials and round
bar stock. A high percentage of alloying elements in the workpiece material results in
reduced lifting capacity.
The load bearing capacities for the most common materials are specified on
page 18.
- The pole faces of the magnet must always be
completely
covered by the workpiece an in
any case to the same extent.
- Never place the magnet on a large hole or bore in the workpiece.
