PROBLEM TO BE SOLVED: To provide a lifting metal fitting for punching-type cable tray, which can support the punching-type cable tray firmly, without the use of a channel material and make effective use of the punching-type cable tray which is suspended and supported using this lifting metal fitting, as electrical equipment positioning system at a ceiling part. SOLUTION: A lifting metal fitting 1 is constituted of a metal fitting body 2, a connection screw 3, and an auxiliary metal fitting body 4. The metal fitting body 2 is of a band plate shape coming into contact with the outer side surface of a parent girder P1. The connection screw 3 connects the metal fitting body 2 to the side surface of the parent girder P1. A parent girder P2 is clamped and fixed between the auxiliary metal fitting body 4 and the metal fitting body 2. A plurality of electrical equipment appliances R are provided side by side, using the lower surface of a punching-type cable tray P which is suspended and supported with the lifting metal fitting 1. It is thus possible to firmly-support the punching type cable tray without the use of a channel material. Effective use of the punching-type cable tray suspended and supported can be made, using the lifting metal fitting as an electrical equipment positioning system at the ceiling part. |
