Réf. : 304 130 03 B H ø A 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.
