The invention discloses a crane hoisting mechanism with an anti-falling type hand-operating device for a nuclear power station. The crane hoisting mechanism comprises an electric motor, a winding drum set, a brake, a brake wheel shaft coupler, a speed reducer and a handle mechanism, wherein a friction sheet I, a friction plate, a fixed plate, a friction plate and a friction sheet II of the handle mechanism are sequentially arranged on the shaft sleeve in a penetrating and sleeving mode; the shaft sleeve is arranged at the front section of a flange shaft sleeve of a flange in the sleeving mode; a central screw hole of the hand wheel is screwed in right-hand threads at the middle section of the flange shaft sleeve; a retainer ring is arranged at the rear section of the flange shaft sleeve of the flange in the penetrating mode; all parts are fixed together by virtue of a disc spring and a nut; springs is arranged between the external circumference of the fixed plate and a fixed flange; and the other end of the fixed flange is fixed on a fixed base through a pin roll. The crane hoisting mechanism has the beneficial effects that the load is prevented from automatically dropping, the structure is simple, the arrangement is convenient, the dismounting is convenient, and the same set of device can be used for multiple hoisting mechanisms.
