At least one guide rail 310 is arranged vertically around the support 10, and guide grooves 311 are formed on both sides of the guide rail 310 to connect the inside of the mounting base 12 of the lighting fixture 11. The stage is inserted and connected so that it is lifted and lowered along the guide rail 310,
A brake unit 300 is provided on the mounting base 12 of the lighting fixture 11, and the brake unit 300 includes a stopper 320 fixed to the lighting fixture mounting base 12 and an inner end of the stopper 320. A tooth-shaped contact end 322 that can be in contact with or spaced apart from the guide grooves 311 on both sides of the guide rail 310, and the outer end of the stopper 320 is a wire rope guided by a lifting guide roller 14. It is connected to (15) and includes a tension spring (323) connected in the opposite direction of the wire rope (15) to perform a pulling action,
remind A proximity detection sensor unit 200 is installed around the lower part of the lighting tower support 10 to detect the approach of an object within the falling radius of the lighting fixture. However, the proximity detection sensor unit 200 performs a proximity detection function only when the lighting fixture is raised and lowered, and the proximity detection sensor unit 200 generates a warning and generates a proximity detection signal when a user or worker approaches within the falling radius of the lighting fixture. A smart elevating safety lighting tower characterized in that it is authorized by the control unit 400 to stop all operations of the lighting fixture. delete
