Disclosed is an apparatus for automatically equalizing tension of main ropes of an elevator suspended to the main ropes so as to move up and down. A structure of the apparatus is simplified so that the apparatus is easily fabricated and installed with improving a tension equalizing function. The apparatus has a plurality of movable pulleys coupled with ends of the main ropes, which are coupled to a car or a count weight and aligned in a machine room or a hoistway, through rods and rope coupling members, a fixed pulley section supported by a beam and having a plurality of fixed pulley sheaves installed in a single block in a longitudinal direction of the single block, a compensating rope aligned between the movable pulleys and the fixed pulley section so as to allow the movable pulleys to move depending on tension of main ropes coupled with the movable pulleys, and a housing for properly positioning the above components. The apparatus is easily manufactured, conveyed and installed while completely solving uneven tension of the main ropes, thereby reducing labor force required for managing the elevator. |
