ラムをボイラ支持鉄骨に据付けるものである。 In the present invention, after the lifting device is installed on the boiler supporting steel frame as described above, the step rod of the lifting device is lowered and first connected to the U-bolt, and then the drum is attached to the U-bolt. Then, the drum and the U-bolt are integrated, and then the step rod of the lifting device is lifted to lift the drum and the U-bolt to a predetermined position.
The drum is installed on the boiler support steel frame via the U bolt by fixing it to the bolt support beam and separating the U bolt and step rod.
このように本発明によれば前記Ｕボルトをして
ドラム吊揚用部材を兼用せしめることによつて、
ボイラ支持鉄骨梁上に１回据付けられた揚貨装置

るものである。 In this way, according to the present invention, by using the U-bolt as a drum lifting member,
A lifting device installed once on the boiler supporting steel beam lifts the U-bolts and drum at the same time.
This greatly simplifies the work compared to the conventional method of hoisting both cargoes separately.Furthermore, according to the present invention, the initial hoisting work is performed by a single hoisting device, and as described above, The present invention has many advantages, such as eliminating the need for an eye plate with a drum because the U-bolt also serves as a lifting member.
以下本発明を図示の実施例について説明する。 The present invention will be described below with reference to the illustrated embodiments.

ある。 The jack up device 2 constituting the aforementioned lifting device is installed on the boiler support steel frame 1, and then the step rod 3 of the jack up device 2 is lowered and connected to the U bolt 4, and then the U bolt 4 is connected as shown by the dotted line. The boiler drum 5 is attached to the drum 5 and the U-bolt 4 is then operated by operating the jack up device 2 to pull up the step rod 3.
After hoisting the U-bolt 4 to the predetermined position shown by the solid line, the U-bolt 4 is fixed to the U-bolt support beam 6 and the boiler drum 5 is installed in the predetermined position.The U-bolt 4 and step rod 3 are then cut. It is something to let go.
