CIRCULAR LIFTING ELECTROMAGNET
SCOPE
The CGMAs are circular lifting electromagnets
recommended for :
– loading and unloading trucks and
railroad cars ;
– cleaning worksites, roads or railways ;
– eliminating bulky ferrous materials
or industrial remnants ;
– steel and cast iron foundries.
TECHNICAL DESCRIPTION
The CGMAs consist of a single-block
frame forming a high-performance
magnetic circuit. The main components are :
– a ribbed foundry frame made of high
magnetic permeability cast steel. The
mechanical fittings and support
surfaces are machined ;
– three suspension rings with pins and
washers ;
– an aluminum conductor winding with
reinforced insulation ;
– a wear plate made of non-magnetic
manganese steel ;
– a fill-in resin blocking and insulating the
coil in the frame (H or C class
depending on usage) ;
– a double electric box allowing external
connection while protecting the internal
windings. A bumper cast with the frame
protects them against lateral
mechanical shocks.
INSTALLATION MODALITIES
The CGMAs can be installed on any lifting
device (overhead crane, truck crane,
gantry crane, steam shovel, etc.). They are
designed for individual usage and are suspended
by a chain with three common
suspension ring strands.
The electrical connection is made using a
power cable with 3 large-section
conductors externally protected.
SPÉCIFICATIONS
Performances vary according to various
parameters :
– characteristics of the products to be
treated ;
– characteristics of the ferromagnetic
elements to be lifted ;
– temperature of the products.
Five CGMAs are offered according to
their diameter :
1000, 1150, 1250, 1350, 1500 mm.
ADDED FEATURES
– Sealed cast steel frame extremely
resistant to shocks and wear ;
– Magnetic circuit protection against
external particles and moisture ;
– Weight/power ratio, guaranteeing
maximum maneuverability ;
– Heat dissipation, thanks to slotting ;
– Double connecting box ;
– Duty cycle : 50 % to 75 % depending
on usage.
USAGE MODE
No special servicing or maintenance is
required except for a periodic check of
the electrical connections, suspension
links and frame.
