Japanese Patent Publication No. 2-40134 and Japanese Patent Publication No. 5-6631
No. 8 discloses a technique disclosed in Japanese Patent Publication No. Both of them relate to a fork lift chain of a forklift. In the former, as shown in FIG. 5, a chain protection plate 1 is incorporated in another plate 2 and integrated with the other plate 2 by connecting pins 3. In the latter, as shown in FIG. 6, protective pieces 5 are incorporated into other plates by connecting pins 6 on both sides of the chain 4.

In the above-described prior art, since the protection plate 1 or the protection piece 5 is integrally connected to the chain plate and the connecting pin, the protection plate 1 or the protection piece 5 is moved up and down by the chain. Alternatively, the protective piece 5 rubs against peripheral members such as a piston rod of a chain drive hydraulic cylinder and a mast of a forklift, and only a specific portion is worn away. In particular, when the protective plate or the protective piece is made of resin, it is heated by rubbing heat. There is a problem that the resin melts and the molten resin adheres to peripheral members such as a hydraulic cylinder and a mast of a forklift.

Accordingly, the present invention provides a large-diameter fork lifting / lowering chain in which both sides are formed with guide side surfaces projecting from the upper and lower surfaces of the chain and through which a refueling hose and a pulley are inserted and guided. The object of the prior art is solved by providing a non-metallic protective roller rotatably to protect the forklift from being damaged or impacted by the vibration of the fork elevating chain to peripheral members of the forklift.

The protective roller rotatably provided on both side surfaces of the fork elevating chain is a large-diameter roller which protrudes from the upper and lower surfaces of the chain plate and forms a guide side surface on which the oil supply hose and the pulley are sandwiched and guided. When the fork elevating chain vibrates, the large-diameter roller abuts and interferes with the peripheral members of the forklift, thereby preventing the chain plate from directly abutting and interfering with the peripheral members of the forklift. Further, since the large-diameter roller is rotatable, even if the large-diameter roller abuts or interferes with the peripheral member of the forklift, the sliding contact with the peripheral member of the forklift and the frictional resistance are avoided by rolling.

In the first embodiment, the protective roller 2
Since the connecting pin 3A pivotally supports the protective roller 2 rotatably, the respective plates on the connecting pin 3A cannot avoid some play in the axial direction on the pin. When the protection roller 2 is sandwiched between the offset plate and the washer 4, the rotation of the protection roller 2 is hindered. In the second embodiment, the shaft supported by the protection roller 2 and the respective Since the connecting pin for connecting the plate is separate from the mounting pin and has a different mounting position, the plate is prevented from floating on the connecting pin in the axial direction, and the width of the fork elevating chain does not change in the width direction. Note that the fork elevating chain of the above embodiment may be a leaf chain or a roller chain.

According to the present invention, during operation of a forklift,
Even if the fork elevating chain vibrates due to the vibration and the fork elevating chain collides with or interferes with peripheral members such as a working hydraulic cylinder or a mast of a forklift, a non-metallic material attached to the fork elevating chain, For example, protect the damage of non-hard parts such as resin,
In addition to suppressing the generation of noise due to collision and interference, the protective roller is rotatable, so that the peripheral members of the forklift and the protective roller are prevented from sliding and abrasion by rolling, and uneven wear of a specific portion is prevented. Of the protection roller can be greatly improved, and the protection roller can be made of resin. There is no danger and the pulley is not provided with a flange portion to guide the pulley up and down, so that the effect is remarkable.
