[PROBLEMS] To realize improvement in total productivity and cost reduction of a rotation frame of an upper rotation body and to enable the rotation frame to cope with a model change easily. [MEANS FOR SOLVING PROBLEMS] A large number of models with different lifting capacities are classified into classes each consisting of plural models, a rotation frame (17) is established using a model having the greatest lifting capacity in each of the classes, and an upper rotation body is constructed using the rotation frame (17) as the base. Further, each winch (5-7) is installed on a rotation frame by using an installation structure standardized within the same class. On the other hand, left and right deck frames (18, 19) are split into sections on each of which different equipment is mounted, and the sections are attached to the rotation frame (17) on section-by-section basis. [PROBLEMES] AmEliorer la productivitE totale et rEduire les coUts d'un cadre de rotation d'un corps de rotation supErieur et permettre au cadre de rotation de bien tolErer un changement de modEle. [MOYENS DE RESOLUTION DES PROBLEMES] Un grand nombre de modEles aux capacitEs de levage diffErentes sont classEs en catEgories comprenant chacune une pluralitE de modEles, un cadre de rotation (17) est Etabli A l'aide d'un modEle dotE de la capacitE de levage la plus importante dans chaque catEgorie, et un corps de rotation supErieur est construit A l'aide du cadre de rotation (17) comme base. De plus, chaque treuil (5-7) est installE sur un cadre de rotation au moyen d'une structure d'installation normalisEe au sein de la mEme catEgorie. Par ailleurs, les cadres de plate-forme gauche et droit (18, 19) sont divisEs en sections sur lesquelles diffErentes piEces d'Equipement sont montEes, et les sections sont fixEes au cadre de rotation (17) section par section.
