Abstract (en)
[origin: EP0243564A2] A load transversal (20) has a plurality of suspension lugs (21) through which are guided bolts (22) of supporting eyes (23) of the electromagnets (5). A limit switch (4) is mounted in the lower region on each suspension lug (21). After the electromagnets (5) are placed on the object to be lifted, the load transversal (20) with the suspension lugs (21) and the limit switches (4) mounted thereon are further lowered, the limit switches (4) passing into the region of trip switches (24) which are mounted on the supporting eyes (23) of the electromagnets (5). Once the limit switches (4) are effectively connected to the trip switches (24), it is possible to switch on the electromagnets and thereafter to lift the load. It is not possible to switch off the electromagnets until the load is put down, when the limit switches (4) once again coincide with their relatively high trip switches (24). A main lead (25) leads from the electromagnet (5), and a lead (26) from each of the limit switches (4) to the rectifier (1) on the load transversal (20). <IMAGE>
