CRANE DEVICE
Document Type and Number:
Japanese Patent JP3923577
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To simplify structure of a crane device so as to lower a production cost.
SOLUTION: A structure is built on a deck of a hull, and a crane device main body 6 is arranged travelably in a guide rail 5 of the structure. A winch 22 is arranged below a traveling beam 7 in the crane device main body 6, and a left side hook part 31 and a right side hook part 32 are arranged on a wire W extended from the winch 22. When the left side hook part 31 is used, the right side hook part 32 is fixed in the traveling beam 7, and contrarily, the left side hook 31 is fixed in the traveling beam 7 when the right side hook part 32 is used. In this way, the winch 22 is not necessary to be used for either of the left and right hook parts 31, 32, so that the crane device main body 6 can be simplified. Therefore, the number of parts can be reduced and a production cost can be lowered.
