響を受けるため真の荷重を求めにくい欠点があつ
た。 Conventionally, a load cell for a forklift truck or the like has a structure in which a load cell is provided for each chain in a chain stop portion that fixes one end of a chain to a finger lever and the other end of the chain. For this reason, two load cells are required, which is uneconomical, and there is also the drawback that it is difficult to determine the true load because it is affected by the unbalance of the loads applied to the left and right chains.

る。 An embodiment of this invention will be described below in detail with reference to the drawings. In the drawing, 1 is a mast device of a forklift truck (not shown), an outer mast 2,
The outer mast 2 is lifted by a lift cylinder (not shown).
It consists of an inner mast 3 that is moved up and down along the inner mast 3, and a finger bar 4 for attaching a fork (not shown) is supported on the inner mast 3 so as to be able to move up and down. Further, one end side of two left and right chains 5 is tied to the finger lever 4, and the other end side of each chain 5 is suspended horizontally between the outer masts 2 after bypassing the sprocket 6 supported by the inner mast 3. It is tied to the link 8 of the horizontal rod 7.

のロードセル１０の両端が取付けられている。 The links 8 are a pair of left and right, each having an inverted L shape, and the bent portions are rotatably supported on the horizontal rod 7 by pins 9.
The ends of the left and right chains 5 are connected to the horizontal ends of the links 8, and both ends of one load cell 10 are attached between the other ends of each link 8.

ることができるものである。 Note that by changing the ratio of the side lengths l 1 and l 2 of each link 8, the measurement accuracy can be changed, and by changing the side ratio according to the forklift truck of each mechanism, the load cell 10 can be used in common. . Further, by providing each link 8 as shown in FIG. 3, a compression type load cell 10 can also be used.
この考案は以上詳述したようになるから、図示

０で荷重測定が行なえ大変経済的である。 Since this invention has been described in detail above, the load of the cargo loaded on the fork (not shown) is applied to both ends of the load cell 10 via the two chains 5 and the pair of links 8, so that one load cell 1
Load measurement can be performed at 0, making it very economical.

ル１０を共通して使用することもできる。 In addition, even if there is an unbalance of load on the left and right chains 5, the load applied to the load cell 10 does not change, making it possible to measure the true load and improve measurement accuracy. Even if the model changes, the load cell 10 can be used in common.
なお上記実施例ではフオークリフトトラツクに
実施した場合について説明したが、フオークリフ
トトラツク以外の荷役機械などにも適用できるも
のである。 In the above embodiment, the case where the present invention is applied to a forklift truck has been described, but it can also be applied to a material handling machine other than a forklift truck.
