POWER SUPPLY APPARATUS FOR CONSTRUCTION LIFT EQUIPMENT

摘要

The present invention provides a power supply apparatus for construction lift equipment, wherein said construction lift equipment includes: a cage for transporting workers or construction materials, and a mast for elevating the cage, and wherein said power supply apparatus supplies power to a driving device for elevating the cage and comprises an ENCL panel for receiving three-phase AC power from an external power supply; a conductor unit which is spaced apart from the mast by a predetermined spacing, and to which an R-phase conductor, an S-phase conductor, a T-phase conductor, and an N-phase conductor are removably coupled, and which has a first electric conductor which is formed into the shape of a rail in the axial direction of the mast and connected to the ENCL panel via electricity supply means, wherein said first electric conductor is coupled to the R-phase conductor, the S-phase conductor, and the T-phase conductor; and a current-collecting unit which is coupled to the cage and to the conductor unit such that the current-collecting unit is movable in a vertical direction, and to which a second electric conductor maintained in contact with the first electric conductor is coupled to supply electricity supplied from the ENCL panel to the driving device.
