To provide a positioning method of a crane hoisting accessory and a crane system by that positioning between a hoisting fulcrum and a hoisting accessory can be performed accurately in a previous stage of hoisting a suspended cargo.SOLUTION: In a positioning step S15, the positioning between a hoisting fulcrum 25 and a hoisting accessory 16 is performed by comparing a hoisting fulcrum position PA based on a GPS 22A for a supporting unit and a hoisting accessory position PB based on a GPS 22B for the hoisting accessory. In this positioning step S15, since the hoisting fulcrum position PA and the hoisting accessory position PB are compared with each other, the positioning can be performed so as to reduce the deviation amount of both positions while accurately grasping a positional relationship between the hoisting fulcrum 25 and the hoisting accessory 16. Accordingly, a suspended cargo 60 can be lifted by the hoisting accessory 16 in a lifting step S40 while reducing the deviation amount between the hoisting fulcrum 25 and the hoisting accessory 16 so that the generation of oscillation of the suspended cargo 60 can be suppressed.SELECTED DRAWING: Figure 6

    【課題】吊荷を吊り上げる前段階において、正確に吊支点と吊具との間の位置合わせを行うことができるクレーンの吊具の位置合わせ方法、及びクレーンシステムを提供する。【解決手段】位置合わせ工程S15では、支持部用GPS22Aに基づく吊支点位置PAと吊具用GPS22Bに基づく吊具位置PBとを比べることで、吊支点25と吊具16との間の位置合わせを行う。この位置合わせ工程S15では、吊支点位置PAと吊具位置PBとを比べることで、吊支点25と吊具16との位置関係を正確に把握しながら、両者のずれ量が小さくなるように位置合わせを行うことができる。このように吊支点25と吊具16との間のずれ量を小さくした状態で、吊り上げ工程S40において吊具16で吊荷60を吊り上げるため、吊荷60の振れの発生を抑制することができる。【選択図】図6
