ものである。(2) Conventional Technology A container crane is used for loading and unloading work from a container ship. However, as the size of the container ship increases, repair work may be performed to further increase the lift. Therefore, the legs of the body part of the container crane are replenished. Therefore, conventionally, as one of the methods, it is usual to dismantle the container crane and add the work at the factory. For this reason, not only is it time-consuming and prolongs the repair period, but also the transportation cost for transporting the disassembled members is high and costly. In addition, as one work method for repairing at the site, while lifting the target crane with another crane, the pedestal is separated, then the skeleton part of the upper crane is moved, and the skeleton part is added to the pedestal again. The method of attaching is also adopted. However, according to this method, a large-sized crane is required, and the phase of the pedestal to be added by the suspension of the upper part of the crane body is significantly deviated, which makes accurate centering work difficult. Lifting a crane is dangerous.

Since there is no dismantling work for the entire crane K, it is possible to significantly reduce the labor and work efficiency. In addition, there is no deviation in the phase relationship between the horizontal and vertical projections of the upper and lower parts of the main body of the crane to be separated,
The positional relationship is fixed, and the work of arranging the pedestal for raising the body is facilitated. Further, the lifting operation in the lifting mechanism J is surely performed by the pitch of the holes 30 of the hanging plate 18, and the safe lifting operation is guaranteed. Further, as the members constituting the guide column 1 and the lifting mechanism J, it is sufficient to use a general shaped steel material such as a flat plate or an H shape, the structure is simple, and the manufacturing is economical. Although the lifting height raising method of the container crane K is described in the above embodiment, it is an easy application example to reduce the lifting height using the apparatus S of this embodiment. That is, the lifting beam 4 is raised to the top or a predetermined height,
In this state, the pillars 110 are engaged with each other, the predetermined portions of the pillars 110 are separated, and then the lifting beams 4 are intermittently lowered to join the remaining pillars 110 to each other.

い。The present invention is not limited to the above embodiments, and various design changes can be made within the scope of the basic technical idea of the present invention. That is, the following aspects are included in the technical scope of the present invention. The lifting mechanism incorporated in the guide column 1 is not limited to the mode of the lifting mechanism J shown in the present embodiment, and another measuring type lifting mechanism can be adopted. For example, when the hanging plate 18 is replaced with a round steel rod (hanging rod), the lifting mechanism is a hall type hydraulic jack that holds the round steel rod. Further, it is possible to adopt a continuous lifting mechanism as well as the length-adjusting lifting mechanism. The engagement relationship between the lifting beam 4 and the pedestal 110 is not limited to the bearing mode of this embodiment, and the hanging mode is not excluded.
