PATENTED CIRCULAR LIFTING ELECTRO-MAGNET
SCOPE
Our patented CMPAF and CHPAF series
are circular medium and high-performance
electromagnets equipped with
double concentric 3-pole coiling.
They are recommended for handling large
quantities of bulk products :
– Light machining scrap metal
– Medium scrap metal from metal grinding
– Heavy scrap metal from industrial scrap
– Mixtures from industrial scrap and steel
residues
Their sturdiness and sealness make them
ideal for outside applications or uses in
difficult conditions, such as :
– Scrap metal areas in electric steel
plants and converters
– Truck and wagon loading and unloading
at metal recycling plants
– Batching in the steel foundry industry.
TECHNICAL SPECIFICATIONS
Our CMPAF and CHPAF are made of a
single-unit steel shell protecting the
patented double coiling. Main parts
include :
– a grooved, high magnetic permeability
steel shell. Mechanical adjustments and
mounting surfaces are machined for
added magnet surfacing.
– three double suspension lugs with shafts
and washers
– a double concentric coil with reinforced
insulation
– a manganese-silica steel magnetic wear
plate. This high resistance part is held by
circlips
– a insulation filling resin blocking the coil
in the shell
– a double electrical box cast in the mass,
for external connections and internal coil
protection. An impact absorber in the
shell protects them from mechanical
impacts.
INSTALLATION METHOD
The CMPAF and CHPAF can be installed
on any lifting device (travelling crane,
crane, portico…). Used alone, they are
hung to a three-strand chain with a
common ring.
The electric connection is provided by an
insulated 3-conductor cable.
SPECIFICATIONS
Performance varies depending on various
parameters :
– Treated product features
– Ferro-magnetic part features
– Product temperature
The impact of apparent density on the lifting
performance is shown in the curve on
the back of this page.
There are 5 types of CMPAF and CHPAF,
based on diameter :
1500, 1650, 1800, 2000, 2200 mm.
ANDRIN PATENT
The Andrin patent consists in dividing the
coiling into 2 concentric coils separated
by an intermediate steel pole. The result is
a single longer and deeper magnetic field
with better thermal dissipation.
THE ADVANTAGES
– Sealed steel shell, impact and wear
resistant
– Magnetic circuit protection against
external particles and humidity
– Magnetic distribution field improved by
patent to increase grip on OD of magnet
– Thermal dissipation through grooving
and 3-pole system
– Double connection box
– Operating factor : 50 % to 75 %
depending on use
– Lifting capacity increased by 10 to 12 %
compared with standard devices.
INSTRUCTIONS FOR USE
No specific maintenance required, apart
from regular electric connection, shell and
suspension cable inspections.
