７６７９５号公報に示されている。2. Description of the Related Art A multi-purpose crane that selectively uses a grab bucket and a container hanger uses a lifting rope in common and replaces only the hanger. When using the grab bucket, an electric grab bucket is used. I am trying to do it. The container hanger and grab bucket are detachably attached to the sheave block suspended by the lifting rope. Such a crane is disclosed in JP-A-02-2.
No. 76795.

ら物をホッパに落下させるようにしている。Further, when the bulk is unloaded using the grab bucket, the bulk falls from the grab bucket between the ship and the hopper on the land side. Therefore, a support plate for the bulk is placed between the ship and the hopper. It is installed. When the loose material collects on the loose material receiving plate, the receiving material is set up with the hopper side as the center, and the loose material on the receiving material is dropped to the hopper.
【０００４】なお、ホッパは海側の脚に設置され、コン
テナを置く位置はホッパと陸側の脚との間になってい

【発明が解決しようとする課題】上記のように、ホッパ
は海側の脚に設置され、コンテナを置く位置はホッパと
陸側の脚との間になっているので、海側の脚と陸側の脚
との間隔が極めて大きくなる。As described above, since the hopper is installed on the sea-side leg and the container is placed between the hopper and the land-side leg, the sea-side leg and the land-side leg are placed. The distance from the side leg becomes extremely large.
【０００６】そこで、海側の脚と陸側の脚との間をコン
テナの置き場所とし、陸側の脚よりも陸側にホッパを設
置することが考えられる。Therefore, it is conceivable that a container is placed between the legs on the sea side and the legs on the land side, and the hopper is installed on the land side rather than the legs on the land side.

The first receiving plate, first rotating means for rotating the first receiving plate between a horizontal state and a vertical state, and the second receiving plate for the first receiving plate. It is characterized in that the crane is composed of the second rotating means for rotating the plate downward from the connection point with the plate.

The loose material that has fallen from the grab bucket during loading collects on the first receiving plate and the second receiving plate. When the loose material accumulates on the first receiving plate and the second receiving plate, the first rotating plate and the second rotating plate rotate the first receiving plate and the second receiving plate upward. Move and drop the loose objects to the hopper side.

The first receiving plate and the second receiving plate are rotated upward. When raised to a predetermined position, the second rotating means is operated so that the tip of the second receiving plate hangs down. As a result, the first receiving plate stands up, but the second receiving plate hangs down, and the overall height of the receiving plate can be reduced.

And the ropes 81 and 91 are wound up. The tip ends of the receiving plates 61, 70 rise while keeping a straight line. For this reason, the loose pieces on the receiving plates 61, 70 are not the chute 5.
Fall to 1. Therefore, the bulk material can be collected. After that, the ropes 81 and 91 are unwound to restore the original state. Alternatively, first, the winch 90 raises the receiving plate 70 as shown in FIG. 3, and then the winch 80 raises the receiving plate 61 to collect the loose material. Horizontal support plate 6
Although the receiving plate 70 is erected with respect to No. 1, this embodiment only shows that such an operation can be performed, and it is possible if necessary.

Therefore, the glove bucket 49 does not interfere with cargo handling. When the pillars 101, 101 are traversed over the stock, they interfere with the loose objects falling from the receiving plate 61, and the lengths of the ropes 81, 91 become long. This is not the case when the plates 61 and 70 are traversed.
