The frame 10 includes support pins 60 which are provided on inner surface of the legs 11 and support the attachment 50, the adapter 52 includes an opening 70 into which the support pin 60 is inserted in a relatively rotatable manner. In the state where the attachment 50 is arranged on a deck 2 of the ship 1, the support pin 60 is inserted into the opening 70 of the adapter 52 in a process where the frame 10 rotates, thereby the attachment 50 is scooped up and connected by the frame 10. |
