The invention discloses a cantilever I-shaped steel dismantling and hoisting device and method, and relates to the field of scaffold dismantling. The cantilever I-shaped steel dismounting lifting and releasing device comprises a support connected to a building, a winding roller connected to the support, a lifting and releasing rope with one end wound around and connected to the winding roller, an anti-falling alarm connected to the support and an I-shaped steel fixing mechanism, and the lifting and releasing rope penetrates through the anti-falling alarm in a sliding mode and then is connected with the I-shaped steel fixing mechanism. When the sliding speed of the hoisting rope exceeds the first preset speed and the second preset speed, the anti-falling alarm gives an alarm sound and locks the hoisting rope; the I-shaped steel fixing mechanism comprises two I-shaped steel clamping blocks which can move in the direction close to each other or away from each other to clamp or loosen I-shaped steel, one I-shaped steel clamping block is connected with a clamping bolt, and the clamping bolt moves when rotating so that the two I-shaped steel clamping blocks can keep away from each other or move in the direction close to each other. The cantilever I-shaped steel dismounting and hoisting device and method can stably, reliably and safely clamp and fix the I-shaped steel and lower the I-shaped steel to the ground.
