Abstract

PURPOSE:To provide a safe method of erecting or putting down a long-sized material without causing rolling of a removed hanger. CONSTITUTION:To erect or put down a long-sized material using two overhead cranes 1, 2 which can approach and separate from each other, a second suspension point B at which the long-sized material 15 is suspended at one end by the second overhead crane 2 is set, with respect to a first suspension point A at which the long-sized material 15 is suspended at the other end by the first overhead crane 1, to a position horizontally separate by a predetermined distance L from a vertical line V passing the first suspension point A of the long-sized material 15 being suspended at the first suspension point A using a hanger 17 attached to the other end of the long-sized material 15. When the long-sized material 15 is suspended in its vertical position, the first 1 and second 2 overhead cranes are disposed at a predetermined interval L in respective positions immediately above the first A and second B suspension points, respectively. Therefore, the suspension rope body of the second crane extends along the vertical direction with the long-sized material in its vertical position.

In the above structure, when erecting a long material in a horizontal position, both cranes are placed directly above the first suspension point on the one end side and the second suspension point on the other end of the long construction material, respectively. The second crane is hooked at the first suspension point, the second crane is suspended at the second suspension point via a hanger member, and one end of the long material is lifted by the first crane to incline and then
The long member can be placed in the vertical posture by loosening the hanging rope of the crane and moving the second crane closer to the first crane to the set distance at the same time. You can also lay it down in the reverse order of the above. In this vertical state, the hanging rope of the first crane does not incline as in the conventional case but follows the vertical direction. Therefore, the suspending tool locked at the second suspending point does not easily come off, and even when removed, it is safe without swinging the suspending tool.
