A nuclear power station hoisting trolley with double rectangle steel wire rope upwards-guiding rope winding systems comprises a trolley frame, a lifting driving mechanism, a steel wire rope winding system, a trolley running mechanism and a lifting appliance. Each steel wire rope winding system comprises a winding drum, an upper pulley set, a lower pulley set, a transition pulley set and steel wire ropes; one ends of the steel wire ropes are wound on the winding drum, and the other ends of the steel wire ropes wind around the lower pulley set, the upper pulley set and the transition pulley set and are finally wound on a winding drum set; the steel wire ropes are guided from the upper portion, and the nuclear power station hoisting trolley with two rectangular steel wire rope cross winding systems is formed. The nuclear power station hoisting trolley has the beneficial effects that the systems are suitable for large-lifting-weight nuclear station crane trolleys, the driving capacity needed by a single electric motor, a speed reducer and the like is reduced, the equipment manufacturing and maintenance cost is reduced, the application range is wide, and the trolley can be used for a nuclear station circle crane and a spent fuel container crane and also can be used for other cranes which are used for lifting and transporting dangerous loads and need to achieve single failure protection.
