用するといった問題がある。In the prior art, the mounting portion of the main rope superimposing compensating rope is on the bracket attached to the outside of the vertical frame of the counterweight. There is no safety device to support the rope weight compensating rope, which may cause a serious accident due to the falling structure. Also, after attaching the main rope weight compensation rope, it becomes difficult to unload the weight,
Due to the mismatch between the core of the main rope weight compensating rope and the core of the counterweight, there is a problem that an eccentric load acts on the guide device of the counterweight.
【０００４】本発明の目的は、強度的な不安がなく安全
性の高いエレベータ用つり合いおもりを提供することに
ある。[0004] It is an object of the present invention to provide a counterweight for an elevator which is safe and free of strength concerns.

整が可能になる。According to the above construction, since a space is created in the center of the counterweight, the inside of the counterweight, that is,
The main rope weight compensating rope can be attached at the hanging core position of the counterweight. In addition, since the lower frame of the counterweight exists below the intermediate beam, the structure has high strength without any anxiety about strength. Further, since the space between the intermediate vertical frame and the outer vertical frame is used for loading the weight, the weight can be adjusted by lowering the weight after the main rope weight compensation rope is attached.
