That is, when the allowable maximum load of the hoisting machine 20 is 1.5 tons, when the two hoisting machines 20 are installed in the Yamakoshi device 2, an allowable maximum load of 3 tons is obtained by one Yamakoshi device 2. .

  Next, as shown in FIG. 5 (B), the branching device 70 to be installed in advance is placed on the transport carriage 73 and carried into the work site, and matches the horizontal direction of the planned installation surface A1. (1st process S1). That is, since the branching device 70 is moved and installed in the gauge direction (lateral direction), when the branching device 70 is carried in, the transfer cart 73 is set so that the branching device 70 and the planned installation surface A1 coincide with the horizontal direction. Stop. Next, as shown in FIG. 5C, the branching device 70 on the transport carriage 73 and the planned installation surface A1 are positioned below the traveling beam 4 in the Yamakoshi device 2 that has been carried near the work site. In such a manner, the Yamakoshi devices 4 are arranged in a line along the branching device 70 and the planned installation surface A1 in parallel with the gauge direction and at almost equal intervals in the track direction (second step S2). At this time, the Yamakoshi device 2 is arranged so that the traveling beam 4 is horizontal. The lower surface of the support leg 5 of the Yamakoshi device 2 may be directly grounded to the ballast roadbed, or may be grounded via a flat plate.

The trolleys 24R and 24L are braked so that the hoisting machine 20 cannot travel. Next, the rail of the branching device 70 is gripped by the rail catch 42 of the hoist 20. When the rail catches 42 of all the hoisting machines 20 grip the rails of the branching device 70, the winding handle 46 of the hoisting machine 20 is then turned to wind up the load chain 43 with the load sheave 41, and the branching device 70 is almost moved. It is lifted up to a predetermined height while maintaining the level (in the Yamakoshi device 2 of this embodiment, the leg length is 1300 mm and the effective lift is set to about 500 mm) (third step S3).

  When the branching device 70 is lifted up to a predetermined height, the operation lever 54 of the braking mechanism 50 is then operated in the reverse direction to release the braking of the trolleys 24R and 24L. Next, the traveling handle 29 is rotated, the suspended branching device 70 is moved laterally along the traveling beam 4 and transferred to the planned installation surface A1, and when the branching device 70 reaches a position directly above the planned installation surface A1. Then, the operation lever 54 of the braking mechanism 50 is operated to brake the trolleys 24R and 24L, and the branching device 70 is stopped at a position directly above the planned installation surface A1 (see FIG. 6D, fourth step S4). . When the branching device 70 is stopped at a position directly above the planned installation surface A1, next, the winding handle 46 is turned in the reverse direction to unwind the load chain 43 from the load sheave 41 and keep the branching device 70 substantially horizontal. Are gradually lowered and suspended on the planned installation surface A1. When the branching device 70 is hung on the planned installation surface A1, the rail of the branching device 70 is removed from the rail catch 42, and the Yamakoshi device 2 and the branching device 70 are separated (fifth step S5). The Yamakoshi device 2 separated from the branching device 70 is removed and the operation is completed as shown in FIG. As described above, in the method for transferring a long heavy object using the Yamakoshi device 2 according to the present embodiment, when the branching device 70 is moved to the desired installation planned surface A1, the work is performed only by using the plurality of Yamakoshi devices 2. Therefore, it is not necessary to use large heavy machinery or to install rolling equipment for transfer in advance, so that work efficiency is improved. In addition, what is necessary is just to reverse to the said process, when removing the branch device already installed from the field, for example, when removing the branch device 170 as shown to (E) of FIG. Along the power branching device 170 and the track 72, the Yamakoshi device 2 is arranged in a line, the hoisting machine 20 is arranged on the traveling beam 4 on the branching device 170, and the branching device 170 is lifted ((D) in FIG. 5). (Refer to FIG. 5 (C)), the transporting carriage 73 is prepared on the track 72, the lifted branching device 170 is transferred onto the transporting carriage 73 and suspended (see FIG. 5C), and the Yamakoshi device 2 is connected to the branching device 170. What is necessary is just to cut and remove and to carry out the branching device 170 with the conveyance trolley 73 (refer (B) of FIG. 5).

And the maximum length L2 in the gauge direction (lateral direction) of the surface formed by the installation planned surface A1 is within the range of the effective travel path length L1 of the travel path of the Yamakoshi device 2 (L2 <L1, FIG. 7B), as shown in FIG. 7A, the distance of the final planned installation surface AF is far away from the branching device 70 carried into the site, and is lined up in the second step. Suitable for the case where there is no plane AF to be installed in the travel path 6 of the Yamakoshi device 2 placed on the outside of the Yamakoshi device 2 It is. In other words, the maximum length L3 in the gauge direction of the surface formed by the loaded branching device 70 and the planned installation surface AF is equal to or greater than the effective traveling path length L1 of the traveling path of the Yamakoshi device 2 (L3> L1, FIG. 7). (See (A)).
