CIRCULAR LIFTING ELECTROMAGNET We provide after-sales service all marks and types of devices. The CSAs 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 CSAs consist of a block forming a high-performance magnetic circuit. The main components are : - a welded frame made of high magnetic permeability 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. INSTALLATION MODALITIES The CSAs can be installed on any lifting device (overhead crane, truck crane, gantry crane, steam shovel, etc.). They are designed for individual usage and are sus-pended 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. USAGE MODE Performances vary according to various : - characteristics of the products to be treated, - characteristics of the ferromagnetic elements to be lifted, - temperature of the products. 11 CSAs are offered according to their diameter : De 500 à 2000 mm. ADDED FEATURES - Welded steel frame extremely resistant to shocks and wear, - Magnetic circuit protection against external particles and moisture, Weight/power ratio, guaranteeing maximum maneuverability, - Double connecting box, - Duty cycle : 50 % to 75 % depending on usage. No special servicing or maintenance is required except for a periodic check of the electrical connections, suspension links and frame OPTIONS • Electric connectors • Electrical control, monitoring and safety equipment (contactor or static variant) •Special voltage •Protective circling •High hardness refill for supporting surfaces •Independent chains for stabilization •Knob for crane clutch •Sealed version • Special series for handling hot products • Other tailored dimensions up to ø3000 mm.
