The base end of the attachment 30 is rotatably supported by the leading end of the crane 11. In the attachment 30, the suspension line 23 is inserted into the leading end from the base end of the attachment 30. The crane 11 takes an attitude in which the leading end of the crane 11 faces the outside of the deck DB and an attitude in which the leading end of the crane 11 faces the inside of the deck DB. Two sheaves 25A and 25B are attached to the connection of the base end of the attachment 30 and the leading end of the crane 11, and the suspension line 23 is sandwiched between the two sheaves 25A and 25B. <P>COPYRIGHT: (C)2012,JPO&INPIT |
