A magnetic fluid levitation moving platform device comprises a moving vehicle, a magnetic fluid levitation device, a levitation platform, a hydraulic device and a controller, wherein the magnetic fluid levitation device and the hydraulic device are fixed to the moving vehicle. The magnetic fluid levitation device comprises a groove, magnetic fluid and an electromagnetic coil, wherein the groove is formed in the moving vehicle, the magnetic fluid is arranged in the groove, and the electromagnetic coil is arranged on the groove. The levitation platform comprises a floating platform and a platform body. The hydraulic device comprises a reverse pushing guide rail and a hydraulic cylinder. The controller controls the electromagnetic coil to generate a magnetic field, the magnetic fluid is magnetized through the magnetic field, the specific gravity of the magnetic fluid is increased, the levitation platform is suspended on the magnetic fluid, the controller controls the hydraulic device to drive the levitation platform to move on the magnetic fluid, the levitation platform is suspended in the magnetic fluid and moves, and therefore the problem that the levitation platform shakes in the moving process is effectively solved, and damage to precision parts which need to be installed in a moving mode or precision dies which need to be installed in a moving mode caused by shaking of the levitation platform in the moving process is avoided.
