The invention discloses a rotary lifting emergency escape ladder. After the rotary lifting emergency escape ladder is hauled to a pointed position by a vehicle or other motor-driven vehicles, four balanced supporting legs of the ladder are stretched under the action of a hydraulic system; a rotary platform is arranged on a pedestal; the rotary platform on a rotary base plate can rotate left and right; two hydraulic cylinders support a portal frame on the rotary base plate; a middle telescopic main frame and a lower telescopic main frame of three groups of telescopic main frames in the portal frame sequentially descend downwards under the actions of a self-locking motor and a steel rope at the top of the portal frame and under the action of a pulley block in turn; and after the middle telescopic main frame and the lower telescopic main frame descend to a certain depth, a telescopic frame stabilizing device stretches out and is then connected with a fixed object. The telescopic main frames, a buffering table, a bottom bridge and a ground bridge form a safe passage together. The rotary lifting emergency escape ladder has the advantages that: the ladder can be uprightly fixed, can be moved to any position to continuously carry in a way of a rolling lifter, can quickly ascend and descend to convey rescuers or goods from high-rise buildings above ground and from underground fields at a certain distance from the ground, and is safe, reliable, quick and convenient in use.
