保するようにしていた。Conventionally, there is a method of increasing the self-supporting height of a climbing crane by using a combination of an inner mast and an outer mast.As shown in Fig. (3) Lift the inner mast (I17a = radius 0? 71 distance, that is, place it at the center of the existing inner mast (1) on the pedestal (4),
5) is placed on the existing inner mast (1) from the top and assembled, and then the revolving body (2) is raised again using the lifting device (6) installed on the inner mast +11. The next inner mast (1, 1'f) is taken in, the assembly material is then further raised by the revolving body (2), the above steps are repeated as appropriate to complete the inner mast (1) to a predetermined height, and then the second As shown in the figure, the outer mast (7) is sequentially assembled to the outer periphery of the inner mast (1) from below to a predetermined height, and then the inner mast stay (8) is attached to the outer mast ( 7) to the required height position, the inner mast (Il'f) was supported, the inner mast (1) was taken in again, assembled, and raised to secure the required height. .

By positioning the leg (2) at the midway positioning part (end) and fixing it to the upper end of the main column (7a) of the outer mast (7) with the tip 7 holding fitting C311 of the leg (2),
The load from the inner mast +- (11 side is transmitted to the outer mast (force side) via the telescopic frame @ (see Fig. 17).

建立することもできる。In addition, if a high self-supporting height is not required, that is, if only the inner mast (1) is sufficient, as an application example of the present invention, the crane can be erected by installing the telescopic frame directly on the foundation fII. .
如上のように本発明によれば、
(1) 内マスト側の荷重を外マスト側にて受けるこ
とができるので、ガイドマスト、ローラ、閂等の昇降装
置は、昇降中の荷重のみを負担すればよく(通常作業時
のモーメント、荷重は昇降時荷重に対して圧倒的に犬で
ある)、従って該部分の小型化、軽量化を図れる。As described above, according to the present invention, (1) The load on the inner mast side can be received on the outer mast side, so the elevating devices such as the guide mast, rollers, and bolts only bear the load during elevating and lowering. (The moment and load during normal work are overwhelmingly larger than the load during lifting and lowering), and therefore the part can be made smaller and lighter.
(II) l記(1)項により荷重の流れがシンプル
となろので、内マストと外マストとの間の1ガタ」が生
ずる心配が少く、クレーン全体の撓みを小さくでき、更
にメンテナンスの心配がなく安全性の向上が図れる。(II) Since the load flow is simple due to item 1 (1), there is less worry about "one play" occurring between the inner and outer masts, the deflection of the entire crane can be reduced, and there is no need to worry about maintenance. Safety can be improved without any problems.
(III) 作業半径□m(又は0m付近)の確保が

。(III) It is no longer necessary to secure a working radius of □m (or around 0m) and the fulcrum of the jib can be moved forward compared to before, so the jib can be shortened and economical, and the rear turning radius can be reduced. Since it can be made small, it is advantageous for working in narrow spaces.
(財)内マストラ、旋回フレームや旋回環の内部を通過
させる必要がないので、該部分の強度アップ、小型化、
軽量化を図ることができる。Since there is no need to pass through the inner mast strut, the rotating frame or the rotating ring, the strength of this part can be increased, the size can be reduced, and
Weight reduction can be achieved.

業員の省力化も図れる。(■) Easier work (especially block formation of the outer mast) as the installation and assembly of the inner and outer masts can be carried out near the ground.
Since there is no need to work at heights, safety is high (and labor savings for workers).
