Abstract

1,181,649. Supply systems for lifting-magnets. HEINRICH KOPPERS G.m.b.H. 8 Jan., 1969 [30 May, 1968], No. 1086/69. Heading H2H. Device for indicating the support of a load by an electromagnet comprises a switch, actuated by the load, which controls the energization of both the magnet itself and an indicator lamp. As shown in Fig. 1, a magnet 3 is to be used for removing the lid 2 from a coke oven charging hole 1, and is provided with a plunger 4 for engaging the lid. In operation, a main switch 6 is closed and then the magnet is lowered on to the lid when the plunger 4 will be operated to close a switch 5 energizing the magnet and actuating a relay 7 in the magnet circuit to close a pair of contacts in a supply circuit for a lamp 8. If the magnet fails to lift the lid 2, the switch 5 will open, de-energizing the lamp and the magnet. The relay 7 may also be adapted to control associated apparatus and to energize a warning lamp.
