して危険である。BACKGROUND OF THE INVENTION Very generally, a container-mounted lift yoke or spreader is supported at one point (via one lift block). If the center of gravity of the container and the lift yoke attached to this container are not located vertically below the bearing point of the lift, the container is tilted, i.e., out of its proper horizontal position. If such an inclination occurs, the load of cargo or the like in the container moves, which is dangerous.
【０００３】従つてリフトによる支持点（リフトブロツ

に調整されることが要求される。Therefore, it is required that the support point (lift block) by the lift be accurately adjusted with respect to the center of gravity of the container and the lift yoke.

The support column is mounted longitudinally movable with respect to the central beam of the lift yoke or spreader. In the preferred embodiment, movement of the support columns can be accomplished by an electric motor.

This is achieved by a lift yoke, which is provided so as to be movable in the longitudinal direction of the yoke, and is provided with a device for pivotally supporting and fixing the support frame 6 to the yoke.

効にコンテナの傾きを防ぐことができる。In the lift yoke according to the present invention described above, the support frame is pivotally supported by the central frame of the lift yoke, and upward power is applied to the upper end portion of the support frame to move the support frame along the longitudinal direction of the lift yoke. Since it is provided, the tilting of the container can be effectively prevented with a simple, lightweight and inexpensive structure.

動に連結する手段が具備される。DESCRIPTION OF THE PREFERRED EMBODIMENT A lift yoke or spreader basically comprises a central frame 1 and two extension beams 2, each extension beam 2 being provided with a transverse beam 3, and the transverse beam 3 being provided at each end thereof. An end piece 4 is arranged. The transverse beam 3 and the end piece 4 are provided with means for movably connecting the container 5 indicated by the dotted line.

（図示せず）のリフトブロツク９が枢支される。A support frame 6 is pivotally supported on the central frame 1, and a pivot shaft 7 of the support frame 6 is perpendicular to the longitudinal axes of the central frame 1 and the extension beam 2. When the support frame 6 is tilted,
It can be effectively adjusted by means including a double-acting hydraulic cylinder arrangement 8 pivoted on the support frame 6 and the central frame 1, respectively. A lift block 9 of a crane (not shown) is pivotally supported on the upper end of the support frame 6.

る。In the figure, the whole is shown by a solid line when the support frame 6 is in a normal vertical position, and a part is shown by a broken line when the support frame 6 is in two inclined states. Actually, the distance between the vertical position and any one of the maximum tilt positions is about 1.2 m.

全に水平位置に保持され得ることになる。However, when the lift yoke or spreader is mounted on the container 5 and the lift operation is started, the combination of the lift yoke or spreader and the container is not horizontal and the center of gravity of the container 5 is the lift block 9.
The support frame 6 can be tilted so that the lift block 9 and the center of gravity of the container 5 are accurately aligned when not located directly below the container, so that the container 5 can be held in a completely horizontal position during the lifting operation. become.
