Provided is a hydraulic magnetic levitation elevator. Based on the hydraulic drive and magnetic attraction principle, a hydraulic system drives oil cylinder magnets in oil cylinders, the oil cylinder magnets attract guide shoe magnets on a car, and then the car is driven to move vertically or stop along with the oil cylinder magnets. According to the elevator, the magnetic attraction principle is adopted for replacing cables of a traditional elevator so that personal accidents can be eradicated; the rodless piston oil cylinders capable of being lengthened are adopted for the hydraulic system so that the elevator can operate at an extra-high speed or on an extra-high floor; throttling valves are used for controlling the descending speed under the weight of the car and the gravity of loads so that energy of 50% of stroke in descending can be saved.
