[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1A is a side view of the forklift 1 during loading of a coil C (a coil-shaped steel strip C) which is a cylindrical load. FIG. 1B is an end view taken along line BB in FIG. 1A.

The forklift 1 is of a counterbalance type, and a balance weight 3 is attached to a rear portion of the vehicle body 2. Reference numeral 4 denotes a head guard, reference numeral 5 denotes a mast, reference numeral 6 denotes a lift cylinder, reference numeral 7 denotes a tilt cylinder, and a finger board 8 is supported on the mast 5 so as to be able to move up and down.

The pair of forks 11 supported by the finger board 8 can move laterally so as to approach and separate from each other. L is applied to each fork 11 described above.
A hook 12 in the shape of a letter is attached. Each of the above hooks 12
A head 13 supported by the fork 11, a trunk 14 protruding downward from the head 13, and a trunk 1
4 and legs 15 projecting inward from the lower side.

The head 13 is formed in the shape of a square pipe and is externally fitted to the fork 11, and slides in the longitudinal direction of the fork 11 as indicated by a dashed line arrow in FIG. It is possible. By tightening a bolt 19 screwed into a screw hole (not shown) in the upper wall of the head 13,
The head 13 is fixed to a predetermined position in the longitudinal direction of the fork 11. That is, the locking means D is constituted by the bolt 19 and the screw hole. When the bolt 19 is loosened, the fixed state is released, and the head 13 is allowed to move in the longitudinal direction. As shown in FIG. 1B, the leg portions 15 are inserted into the cylindrical hole 17 of the coil C by moving the forks 11 inward and laterally.

The procedure for using the hooks 12 will be described with reference to FIG. As shown in FIG. 2, the coil C received with the cylindrical hole 17 facing the vehicle T in the vehicle width direction is unloaded from the truck T in the following procedure. That is, as in the conventional case, the forks 11 of the forklift 1 are replaced with rams 25, and the forklift 1 is moved toward the center of the truck T in the vehicle width direction, and the ram 25 is inserted into the cylindrical hole 17 of the coil C. Then, the coil C is lifted and unloaded by the ram 25.

The loaded coil C shown in FIG. 2 can be unloaded by the following procedure instead of the above procedure. First, a pair of forks 11. 1 of the forklift 1
Put 1 around the center. Next, in this state, the forklift 1 is run in the same manner as described above, and the assembled forks 11 are inserted into the cylindrical hole 17 of the coil C. Thereafter, the coil C is lifted and unloaded by the forks 11.

On the other hand, as shown in FIG. 3, when the coil C is received with the cylindrical hole 17 facing the front and rear direction of the truck T, first, the fork 11
Each of the hooks 12 is attached to the above. More specifically,
The head 13 of the hook 12 is externally fitted to the fork 11, and the head 13 is fixed at a predetermined position in the longitudinal direction of the fork 11 by a locking means D (see FIG. 1A).
In addition, the pair of forks 11, 11 is previously widened to a value sufficiently larger than the dimension (band width dimension) W between both end faces of the coil C.

Next, the forklift 1 is moved toward the center of the truck T in the vehicle width direction, so that the pair of forks 11,
Into the space on the side of both ends. Subsequently, the legs 15 of the hooks 12 are inserted into the cylindrical holes 17 of the coils C by laterally moving the forks 11 inward (see FIG. 1B).・ 1
1 is lifted and the coil C is transported to a predetermined place. The hooks 12 are connected to the coil C from the track T.
Of course, it is also possible to use it when loading the coil C on the truck T instead of unloading.

The above embodiment can be modified as follows. The forklift 1 may be a forklift of another type, such as a reach type or a side type, instead of the counterbalance type as illustrated. The above-mentioned cylindrical luggage may be another kind of luggage such as a carpet or a tire rolled in a spiral shape, instead of the illustrated coil C.

It is preferable to use an actuator such as a hydraulic cylinder for the lateral movement of the pair of forks 11, but the forklift 1 may be moved by the limbs of the operator. The lock means D is configured such that a bolt 19 is screwed onto the head 13 of the hook 12,
A fitting structure of a pin penetrating the head 13 and a locking hole formed in the fork 11 may be used.

[0018]

According to the first aspect of the present invention, the following effects can be obtained from the configuration and operation described above. By inserting the leg of the hook attached to the fork into the cylindrical hole of the cylindrical luggage and lifting the fork, the above-mentioned cylindrical luggage can be loaded and unloaded, so that the direction of the cylindrical hole of the cylindrical luggage is different. Even so, the cylindrical luggage can be reliably handled by the forklift.

According to a second aspect of the present invention, the head of the hook is externally fitted to the fork so as to be movable in the longitudinal direction, and the head is fixed at a predetermined position in the longitudinal direction of the fork by locking means. In the case where the fixing and releasing of the fixing are possible, the mounting position of the hook can be easily adjusted in accordance with the type and size of the cylindrical luggage, so that the loading / unloading operation of the cylindrical luggage does not take much trouble.
