Abstract

PURPOSE: To provide a lifting magnet excitation amplitude and wave length controller ensuring control for lifting and lowering steel without any operator's observation.
CONSTITUTION: A wireless apparatus 12 for transmitting signals to and receiving signals from a computer in a ground controller 15, a relay panel 13 for controlling a lifting magnet 10, a magnet lift drive motor 14, an excitation apparatus 19 and a magnet width drive motor 17 for controlling the width of two auxiiary magnets 18 attached to the magnet 10 are arranged on a crane 11 for lifting or lowering steel through the magnet 10. The controller 15 is equipped with the computer which is adapted to calculate an interruption signal and steel yard data to provide a control command thereby directly controlling the excitation width and length of the magnet 10 according to the command.
