Abstract
Disclosed is an apparatus for automatically equalizing tensions of elevator wire ropes by which an unbalance of tensions of elevator wire ropes can be immediately solved to automatically equalize the tensions in real time when lengths of the wire ropes become different, improving safety, durability, and reliability. The apparatus according to the present invention includes a body (100) having an accommodation space therein, a tension adjusting unit connected to elevator wire ropes (R1˜R4) and installed within the body (100), a main shaft (200) passing through the tension adjusting unit and rotatably coupled to an inner side of the body (100) horizontally; and first to fourth guide rollers (B1˜B4) rotatably coupled to the body (100) such that the elevator wire ropes (R1˜R4) connected to the tension adjusting unit contact the first to fourth guide rollers (B1˜B4) at outer sides thereof.
