A safe suspended scaffolding for high-rise construction, wherein a suspended scaffolding mechanism (2) is mounted on a building (1). The suspended scaffolding mechanism (2) comprises a first steel wire rope (4), a first unwinding mechanism (5), a first fixing plate (6), a second unwinding mechanism (7), a second steel wire rope (8), a T-shaped strip (9), a fixing housing (10), a first motor (11), a carrier housing (12), and so on; the first fixing plate (6) is mounted on a side surface of an upper end window (3) of the building (1), and an upper end surface of the T-shaped strip (9) is mounted on a lower end surface of the first fixing plate (6); the first unwinding mechanism (5) and the second unwinding mechanism (7) are both mounted on the lower end surface of the first fixing plate (6) and are provided symmetrically relative to the T-shaped strip (9). The safe suspended scaffolding for high rises may effectively avoid obstacles on the ground, thus protecting workers and objects in the suspended scaffolding.
