Abstract

A lifting magnet arrangement. The arrangement has a thrust direction in which a pressure spring which biases the armature into its basic position may be set. This is done by an actuating section designed to project from the magnet housing. By using this configuration it is not necessary to open the magnet housing for adjustment so that the adjusting process may be carried out with an oil-floated armature.
