Further, a hydraulic cylinder 27 is fixed to a substantially central portion of the front and rear frame 15 by a cylinder receiver 26, and a tip portion of a cylinder rod 28 is fixed to a continuous frame 29 provided laterally between the bifurcated chatch bodies 24 and 24 '. . Therefore, the bifurcated catch bodies 24, 24 '
Is moved up and down by the hydraulic cylinder (Figs. 2 and 3).

The bifurcated catch bodies 24, 24 'are provided with two catches 3 facing the two leg portions 30, 31 formed by forming notches in the direction for holding a long load.
2 and 33 are provided, and these can be freely moved in and out by a hydraulic cylinder as a catching-in / out means. Here, the distance between the catches 32 and 33 in the notch is larger than the entire width of the one side flange of each loaded H-section steel.

The apparatus for gripping a suspended load having the above structure moves the H-section steels A, B, and C from the warehouse exit table 2 to the roller conveyor 5 as follows.

First, the drive motor 9 is operated by wire or wireless remote control to move the wheel 10 to the left from the state shown in FIG. 1 and the bifurcated catch bodies 24, 24 'are loaded on the warehouse exit table 2. It is located on one side flange 3 of H-section steel A. In this case, by setting a distance equal to or longer than the width of all the flanges 3 of the H-section steels A, B, and C alternately placed on the warehouse delivery stand 2 as the length H between the tips of the opposite catches 32, 33. The leftmost position where the wheel 10 travels can be preset.

Next, the motor 19 is actuated to move the wheels 14 in the longitudinal direction along the longitudinal direction of the H-shaped steel A loaded on the warehouse exit table, and the two bifurcated catch bodies 24, 2 are provided.
Position 4'to prevent the H-section steel from being eccentrically loaded. In this case, for example, the length of H-section steel is 4 m, 8 m or 1
In the case of 2 m, a limit switch can be provided on the track so that the centers of the two forked catch bodies are located at the respective central positions.

In this way, the hydraulic cylinder 27 lowers the bifurcated catch bodies at both ends of the front and rear frames 15 (FIG. 5), and the catches 32 and 33 opposed by the hydraulic cylinders.
It was allowed to protrude to grip the plate thickness of the flange 3 piece side. In this case, the catches 32 and 33 include the same protruding length (FIG. 6), and in addition, as shown in FIG. 8 and FIG. 9, either one of the catches 32 or 33 that first abuts the flange 3 is pressed with a constant pressure. However, in order to stop the other catches 33 or 32 at the same position until they come into contact with each other with the same pressure, the catches 32 and 33 have different projecting lengths and are in surface contact with each other so that the long load is not
The gripped portion may be gripped (FIG. 7).

Further, the above-mentioned hydraulic cylinder 27 raises the forked catch bodies 24 and 24 ', but since the flange gripped by the catch is eccentric from the center of gravity in the width direction of the H-shaped steel, each catch is described above. By applying bending stress in addition to the contact pressure, the H-shaped steel can be gripped more firmly.

H-shaped steel A gripped by catches 32 and 33
Moves to the right on the wheel 10 and stops at the right end of the roller carrier 5, that is, at a predetermined position where the end of the H-shaped steel is drilled with a drill machine, and the hydraulic cylinder 27 is lowered. After dropping the H-shaped steel onto the roller conveyor 5, the catches 32 and 33 are pulled in by a hydraulic cylinder to release the grip. Here, the determined position on the roller conveyor 5 depends on the length and width of the H-section steel and is selected by the limit switch provided on each roller conveyor.

After that, by repeating the above operation,
The H-shaped steel B is moved from the warehouse delivery stand 2 to the roller carrier 5 (FIG. 9).
