<p>PROBLEM TO BE SOLVED: To obtain a cable lifting jig with which the terminal parts of main cables can be suspended in a short time. SOLUTION: The terminal parts of main cables A1, A2 and A3, from which branch lines are branched at a plurality of positions in longitudinal directions, are suspended from a building by a cable lifting jig and fixed to the building. The cable lifting jig has a cylindrical main part 1, whose top part is opened and whose bottom wall 1a has a cable introducing inlet 2, through which the terminal parts of main cables A1, A2 and A3 are introduced into the main part 1, an insulating core block 5 with circumferential cavities 6A, 6B and 6C in which metal sleeves 3 fixed to the exposed conductors (a) of the terminal parts are positioned, and an insulating cap 8 which is put onto the insulating core block 5 after the metal sleeves 3 are positioned, in order to prevent the metal sleeves 3 from falling out of the circumferential cavities 6A, 6B and 6C. Both the insulating core block 5 and the insulating cap 8 are dropped into the cylindrical main part 1, and the top opening part of the main part 1 is closed. A hook metal 10 is fixed to the cylindrical main part 1 in this state.</p> |
