PROBLEM TO BE SOLVED: To simplify the structure of a trolley which moves a transported material storage body, to miniaturize the trolley, and to reduce the weight thereof in a crane which hoists the transported material storage body storing the transported material and moves the transported material storage body in the vertical direction and the lateral direction for loading.SOLUTION: In the crane 1, seesaw type link mechanisms 30A and 30B as a turning mechanism for a straw basket type carrier 6 are provided on a main trolley 10. The seesaw type link mechanisms 30A and 30B have simple structures including links 31a and 31b and support shafts 32a and 32b. By this, in comparison with the case of using a cylinder device as a turning mechanism for the straw basket type carrier 6, the structure of the main trolley 10 can be simplified and miniaturized, and the weight thereof can be reduced. |
