Electrically switched electro lifting magnet VM series

for sheet metalhandling

The VM magnetic grippers are high-performance electromagnets equipped with a concentric winding. The VM electromagnets, which are designed to handle thin sheet metals, must be geometrically placed to limit bendings in all directions. Depending on sheetmetal sizes, the VM grippers will be installed therefore on fixed or telescopic lifting beams. They are recommended for the handling of sheet metals and metal parts in : •oxyacetylene cutting workshops, •shipbuilding yards, •sheet-metal warehouses. TECHNICAL DESCRIPTION The VM grippers are made up of a mechanically fitted-welded steel frame protecting the aluminum or copper winding. The main components are : •a frame made of high magnetic permelability steel. The mechanical fittings and support surfaces are machined for a better reconditioning of the magnets, •a suspension ring, •a concentric winding with reinforced insulation, •a wear plate made of non-magnetic manganese steel. This high-strength part is flanged and welded to the frame, •a fill-in resin blocking and insulating the coil in the frame (H or C class depending on usage), an electric box allowing external connection while protecting the internal winding. INSTALLATION MODALITIES The VMs can be installed on any lifting device (overhead crane, truck crane, gantry crane, etc.). They are designed for individual usage and are suspended by the suspension ring. The electrical connection is made using a cable with 3 large-section conductors externally protected to provide a 110 VDC power supply.
