PROBLEM TO BE SOLVED: To convey a workpiece farther away at a high speed by using a crane.SOLUTION: A fixed pulley 50 is supported by a main wire rope 25A delivered from a first crane 1A and a main wire rope 25B delivered from a second crane 1B, a moving pulley 51 is arranged below the fixed pulley 50, a sub-wire rope 27 delivered from the crane 1A is wound on a sheave 50b of the fixed pulley 50, and then wound on a sheave 51b of the moving pulley 51, and then connected to a shaft 50a, the moving pulley 51 is supported by the sub-wire rope 27, the fixed pulley 50 is displaced by cooperatively controlling the delivered amounts of the main wire ropes 25A, 25B, the moving pulley 51 is displaced by controlling the delivered amount of the sub-wire rope 27, and a workpiece W hooked to a hook 51c is conveyed.SELECTED DRAWING: Figure 2

    【課題】クレーンを用いて、ワークをより遠くへ、かつ、高速で搬送する。【解決手段】第一のクレーン1Aから繰り出したメインワイヤロープ25Aと、第二のクレーン1Bから繰り出したメインワイヤロープ25Bによって、定滑車50を支持し、かつ、定滑車50の下方に動滑車51を配置し、クレーン1Aから繰り出したサブワイヤロープ27を、定滑車50のシーブ50bに巻回した後、動滑車51のシーブ51bに巻回し、その後軸部50aに連結して、サブワイヤロープ27によって、動滑車51を支持し、各メインワイヤロープ25A・25Bの繰り出し量を協調制御することによって、定滑車50を変位させるとともに、サブワイヤロープ27の繰り出し量を制御することによって、動滑車51を変位させて、フック51cに引掛けたワークWを搬送する。【選択図】図2
