PATENTED CIRCULAR LIFTING ELECTRO-MAGNET CMPAF CHPAF SCOPE Our patented CMPAF and CHPAF series are circular medium and highperformance 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. 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. 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. 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, SPECIFICATIONS - Thermal dissipation through grooving Performance varies depending on various and 3-pole system, parameters : - Double connection box, - Treated product features, - Operating factor : 50 % to 75 % - Ferro-magnetic part features, depending on use, - Product temperature. - Lifting capacity increased by 10 to 12 % The impact of apparent density on the lif- compared with standard devices. ting performance is shown in the curve on INSTRUCTIONS FOR USE the back of this page. There are 5 types of CMPAF and No specific maintenance required, apart from regular electric connection, shell and CHPAF based on diameter: suspension cable inspections. 1500, 1650, 1800, 2000, 2200 mm.
