The invention discloses balance hoisting equipment. A first support arm, a second support arm and a third support arm horizontally extend out of a main bracket, wherein a hoisting device is arranged on each support arm, and comprises a take-up roll, a pulley rack and a fixed pulley; each pulley rack is located at one end, far away from the main bracket, of each support arm; each fixed pulley is arranged on the corresponding pulley rack and can move on the pulley rack along the axial direction; the three pulley racks are located at three top points of an equilateral triangle; and a pulling rope guided out of each take-up roll is connected with a hoisted heavy material around the corresponding fixed pulley. The balance hoisting equipment disclosed by the invention is reasonable in structure design; through the three groups of hoisting devices arranged in a triangle, on one hand, the tension on a single hoisting rope can be relieved, and the maximal lifting weight is greatly improved, on the other hand, the three pulling ropes are pulled from three directions at 60 degrees in the hoisting process, the stress balance of the material is kept and the material does not easily shake.
