LIFTING APPARATUS, LIFTING SYSTEM FOR SLAB HAVING THE SAME AND LIFTING METHOD FOR SLAB USING THE SAME

摘要

The present invention relates to a lifting apparatus, a slab lifting system having the same, and a slab lifting method. The lifting system comprises: a crane which moves a slab; a pit which has a loading space where the slab is loaded; and the lifting apparatus which is installed in the loading space. Therefore the present invention reduces the cooling effect of the loaded slab and improves the energy efficiency of a crane and the lifting apparatus by forming a sensor part in the lifting system.
