The invention discloses a method for adjusting deviation of a hoisting point of a hoist, and belongs to the technical field of opening and closing of gates of hydropower stations. The method comprisesthe steps of a, mounting a hoisting point deviation adjusting device on a rack; b, mounting hoist steel wire ropes; and adjusting the steel wire ropes of two hoisting points to be consistent in length; and c, adjusting the two hoisting points to realize balancing through a swinging beam on the hoisting point deviation adjusting device; downwards swinging the swinging beam at one side, bearing high load, of each hoisting point, and releasing the corresponding steel wire rope; downwards swinging the swinging beam at one side, bearing small load, of each hoisting point; coiling the correspondingsteel wire rope, and thus finishing the dynamic adjusting of the balance of the two hoisting points. According to the method, the hoisting point deviation adjusting device is adopted and is capable of timely dynamically adjusting the two hoisting points to realize balancing while the hoist runs, and thus stopping for repairing is saved; the hoist running stability can be ensured; and the adjusting is flexible, simple and convenient.
