Rectangular electro lifting magnet RTA

electrically switchedhandlingtripolar

RTAs are rectangular three-pole electromagnets with an aluminium winding. They are recommended for handling products with a flat surface: •slabs, •ingots, •metal sheets, •beds of extruded section. Their robustness means they are ideal for intensive use in areas such as : •continuous casting, •hot and cold rolling mills, •flame cutting workshops, •steel distribution networks, •shipyards. TECHNICAL DESCRIPTION RTAs consist of a precision-welded steel frame protecting the winding. The main component parts are : •a three-pole magnetic circuit made of high magnetic permeability steel. The mechanical fittings and contact surfaces are machined, •Two double suspension lugs with bolts and washers for a joint-ring two-strand chain, •a concentric aluminium winding with reinforced insulation, •a wear plate made of non-magnetic manganese-silicon steel. This highstrength part is welded to the frame, •filler resin protecting and holding and insulating the winding in the frame (class H or C depending on the application), •a compartmented double electrical box enabling external connections while protecting the internal winding. Standard RTAs can easily be modified to allow special applications : •4 suspension lugs, •lateral handling hooks, •orientation or tipping clevises, •immersion chambers.
