The invention relates to a hoisting tool for a tank type circuit breaker arc extinguish chamber. The hoisting tool comprises a connecting rod group and a counterweight, wherein the connecting rod group is connected with a cover plate of an arc extinguish chamber; the counterweight is mounted on one side, away from the cover plate, of the connecting rod group; the connecting rod group and/or the counterweight are/is provided with an adjustable hoisting structure which is connected with a hoisting mechanism and is used for leveling the arc extinguish chamber in a manner of cooperating with a main hoisting point of the arc extinguish chamber; the adjustable hoisting structure is arranged on the counterweight or the connecting rod group and is used for hoisting by cooperating with the main hoisting point of the cover plate of the arc extinguishing chamber, the weight of the counterweight is calculated in advance according to distances and the like before the main hoisting point is hoisted,and when the upper part of the cover plate of the arc extinguish chamber is used as the main hoisting point for hoisting, the arc extinguish chamber possibly has the slightly-inclined and not completely leveled situations, and thus, auxiliary adjustment is carried out by using the adjustable hoisting structure, the adjustable hoisting structure plays an important role in adjustment of the hoisting levelness of the arc extinguish chamber, so that the horizontal hoisting of the arc extinguish chamber is conveniently adjusted, the hoisting procedure is quickened, the working efficiency is improved, and the difficulty of difficult adjustment levels of horizontal hoisting of the tank type circuit breaker arc extinguish chamber is effectively solved.
