（ア）産業上の利用分野
この発明は昇降台を吊下げるチエンの荷重を均等にする
荷重等配淳軍に関するものである。DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application This invention relates to a load distribution system that equalizes the load of a chain suspending a lifting platform.
（イ）従来の技術及び発明が解決しようとする問題点
従来、昇降台を吊下げるチェン或いはワイヤー（以下単
にチエンと略称す）は昇降台の重量に耐える強度のもの
を２本束ねて、昇降台の四隅の同じ位置に固定している
。このため、その２本のチエンにかかる荷Φが均等でな
いときは、荷重が大きくかかる方のチエンが伸びたり、
切断したりしで危険が少くなかった。(B) Problems to be solved by the conventional technology and the invention Conventionally, the chains or wires (hereinafter simply referred to as chains) used to suspend the lifting platform are made by bundling two chains that are strong enough to withstand the weight of the lifting platform. It is fixed in the same position at the four corners of the stand. Therefore, if the load Φ applied to the two chains is not equal, the chain on which the greater load is applied may stretch, or
There was a lot of danger in cutting it off.

うに構成されている。(1) Means and operation for solving the problems In order to solve the above-mentioned problems, this invention will be explained with reference to the drawings of the embodiment. The load distribution rod (4) is attached to the chain attachment part (6) of (2).
is mounted on a rotating shaft (5)], and chains (6) are fixed to both sides of the load distribution rod (4), so that the lifting platform (1) is suspended.
このように構成されているので、２本で１組になって、
昇降台（１）を吊下げているチエン（６）にかかる荷重
が等しくないときは、第３図のように荷重等配ネＹ（４
）の一端がチエン取付部（３）の上部に接触するまで傾
いて２本のチエン（６）の荷重が均等になるように調整
する作用をなす。Since it is configured like this, two pieces make up a set,
If the loads applied to the chains (6) suspending the lifting platform (1) are not equal, the load distribution Y (4
) is tilted until one end touches the top of the chain attachment part (3) to adjust the load on the two chains (6) to be equal.
また、■の実施態様にあっては、昇降台（１）を吊下げ

動して、昇降台（１）の昇降が停止する作用をなす。In addition, in the embodiment (2), each of the eight chains (6) suspending the lifting platform (1) is connected to the limit switch (8) via the roller (7), so which If one chain (6) is stretched or cut,
As shown in Figure 3, the load distribution rod (4) is tilted and the lifting platform (1
), the limit switch (8) operates to stop the lifting platform (1) from moving up and down.
（１）実施例 以下１図について本発明の詳細な説明すると。(1) Examples The present invention will be described in detail with reference to FIG. 1 below.

る。1 is the ￥r descending platform, 2 is the support at the four corners of the elevating platform 1, 3 is the branch office 2
4 is a load distribution rod, and 5 is a rotating shaft, which is attached to the center of the load distribution rod 4. By this rotation shaft 5, the load distribution cape 4 is connected to the chain attachment portion. 3 is attached to the shaft.
６はチエンにして、昇降台１の四隅をそれぞれ２木で吊
下げ、その２本のチエン６は１木ずつ荷山簀配卑Ｗ４の
左右の端に固定しである。6 is a chain, and each of the four corners of the lifting platform 1 is suspended by two pieces of wood, and each of the two chains 6 is fixed to the left and right ends of the loading rack support W4.
７はローラー、８はリミットスイッチにして。7 is a roller and 8 is a limit switch.
ローラー７は８本のチエン６のそれぞれに接触するとと
もに、リミットスイッチ８に連絡している。The roller 7 contacts each of the eight chains 6 and also communicates with a limit switch 8.
（オ）効果 本発明は上述のように構成し１作用するので。(e) Effect The present invention is constructed and operates as described above.
■の実施態様にあっては昇降台の四隅を吊下げるそれぞ

に同じ状態で吊下げられ、また。In the embodiment (2), if the load applied to each of the two wooden chains hanging from the four corners of the lifting platform is not equal, the load Φ
The distribution rod tilts to adjust the load, so the platform is always suspended in the same condition.
