対の脚１ａ、ｌａの間を走行する。An embodiment of the present invention will be described below. In FIG. 1, an auxiliary crane 2 is placed inside the legs of a container crane (main crane) 1. There is a foundation 4 with sufficient strength under the running rail 3 of the container crane.
There is no special foundation under the running wheels 5 of the auxiliary crane 2. The auxiliary crane 2 is equipped with a conveyor 6 for temporary container storage, a container guide 7, a frame 10 and a winch 11 for lowering the container 9 using a hanging tool 8. The auxiliary crane 2 travels between a pair of left and right legs 1a, la of the main crane.

The lower portions of a are connected by a joint frame 1b. A support stand 13 is installed on the inner side surface of this joint frame 1b. This support metalwork 3 is installed at a spacing between the front and rear legs 14, 14 of the auxiliary crane 13. In other words, there are two support stands 13, front and rear.

かかる荷重を本体クレーンの脚に移す。Next, the operation will be explained. The container 9 carried by the main crane 1 is temporarily placed and moved horizontally by the conveyor 6.
The container is unloaded onto the chassis 17 while being guided by the container guide 7 by the hanging tool 8 and winch 11. At this time,
Since the load on the wheels 5 due to the weight of the container and the auxiliary crane 2 is large, the load exceeds the load capacity of a foundation that is not particularly reinforced. Therefore, before starting cargo handling work, the auxiliary crane 2 is driven and stopped at a predetermined position inside the leg 1a of the main crane 1, and the positions of the support platform 15 on the auxiliary crane z side and the support platform 13 on the main crane side are adjusted. After alignment, the jacks 16 are extended to transfer the load on the legs 14 of the auxiliary crane 2 to the legs of the main crane.
なお、本説明では、ジヤツキを海側の車輪荷重が大きく

構を陸側に取り付け、４コーナともジヤツキアップして
、本体クレーンに荷重をもたせることもできる。In addition, this explanation shows the case where the jacks are installed only on the sea side where the wheel load is large, but a similar mechanism is installed on the land side and the jacks are increased at all four corners to apply the load to the main crane. You can also do that.
本実施例によれば、補助クレーン２の輪荷重を、大幅に
低減できるという効果がある。According to this embodiment, there is an effect that the wheel load of the auxiliary crane 2 can be significantly reduced.
本発明によれば、補助クレーンの車輪荷重を大幅に低減

重が低いパースにおいても、補助荷役装置付クレーンを
導入できるという効果がある。According to the present invention, since the wheel load of the auxiliary crane can be significantly reduced, a crane with an auxiliary cargo handling device can be introduced even in Perth, where the permissible load of the foundation of the travel lane of the auxiliary crane is low.
