PROBLEM TO BE SOLVED: To provide a lifting method capable of safely lifting a body to be lifted by three or more cranes.;SOLUTION: At least three cranes are classified into two groups so that at least one group comprises at least one combination of two cranes. In the combination of two cranes, one wire 21-1 of one crane is connected to one wire 31-1 of the other crane via the corresponding parts to be engaged. The other wire 21-1 of one crane is connected to the other wire 31-2 of the other crane via the corresponding parts to be engaged. Consequently, in lifting, a load applied to one wire 21-1 of one crane and a load applied to one wire 31-1 of the other crane are made equal to a load applied to the other wire 21-2 of one crane and a load applied to the other wire 31-2 of the other crane.;COPYRIGHT: (C)2007,JPO&INPIT
