The present invention discloses a lifting apparatus, comprising: a vertical guide device; a turntable device which is movable along the vertical guide device upwards or downwards; and a first driving device which drives the turntable device moving in an upward and downward direction guided by the vertical guide device. Wherein said turntable device comprises: a bracket which is slidably engaged with the vertical guide device and projects perpendicularly toward a side of the vertical guide device; a turntable which is rotatably provided on the bracket; and a second driving device which rotates the turntable on the bracket. The present invention further discloses a safety inspection system comprising the lifting apparatus. Compared with prior art, the present invention combines a rotating mechanism and a lifting mechanism as a single apparatus, thus, realizing the self rotation and elevation of the objects to be detected. Thus the present invention has the beneficial features, such as high movement precision, high transmission efficiency, low friction resistance and reduced noise etc.
