摘要： A magnetic lifting device having a load lifting magnet with at least one magnetic coil arranged in a housing. A driven synchronous alternator is arranged in a housing for generating a voltage supplied to the magnetic coil. A supply line leading from the alternator to the magnetic coil supplies direct current to the magnetic coil. An electrical switching circuit with a control line arranged within the alternator housing connects to a control switch outside the alternator housing through a further control line outside the alternator housing. The control switch actuates a first rectifier connected to the alternator for powering the coil of the magnet. It also deactivates the magnet by powering a second rectifier of a reverse polarity to release the magnet load. The control switch also includes an overload signal and alarm, and a ready light when the magnet is ready to be powered.
