First, an outer tower gantry 4b is installed around the foot of the outer tower, and after dismantling the inner tower (to be described later), the outer tower is supported by a lift device 5 so as to be able to be raised and lowered via a crown beam 6, and the outer tower components below it are supported. After cutting and removing, the remaining outer area is lowered to the designated position, and this process is repeated to dismantle it. In order to prevent the outside field from falling over, a cantilever beam 11 that projects outward is installed at the node of the outside structure member, and the roller 3 at the tip is connected to the gantry 4.
It comes into contact with the vertical guide rail 10 of b and is transferred. This device is used for raising the height of power transmission towers (Japanese Patent Laid-Open No. 59-96390).

The inner tower is lifted up and down via a hairpin beam 6 by a lift device 5 placed thereon. As shown in Figure ti2, the lift device in this embodiment has a rod 5b secured to a crosshead 5c on a jack 5 erected on the upper side of a gantry 4a by an upper nut 5d, and a lower napft 5 at its lower end.
By locking the loft 5b to the fixed cross and the rod 5c'' with the nut 5f screwed in the middle, or loosening the loft 5b, the stroke F of the jack can be changed. This is to raise and lower the hairpin beam (Utility Model Publication No. 59-11557).

Then, remove the ornamental beam, replace it in the hole 1a'' (not shown) newly made above, hang it again using a rift, and cut and remove the lower part of the inner tower. The inner tower was repeatedly dismantled in its entirety, and the lift equipment and inner tower pedestal were also removed.

Effects of the invention Since virtually all the installation work of machinery and equipment prior to demolition is carried out at the bottom of the steel tower, there is less risk of disasters due to falls or falling accidents, and surrounding buildings and mechanical equipment etc. It is possible to reduce the amount of care required.
鉄塔が内塔を有する場合、外場の解体に先だってこれを
ガイドとして、単に（同時には外場を解体せず）内塔を

果を得ることはい −うまでもない。If the steel tower has an inner tower, it is possible to obtain the same effect by simply lowering the inner tower and dismantling it from below using this as a guide (without dismantling the outer tower at the same time) before demolishing the outer tower. -That's no good.
