The invention discloses a lifting device for yard crane wheels. The lifting device comprises a wheel lifting plate, a first supporting leg, a second supporting leg, a supporting roller, a first supporting arm and a second supporting arm. The first supporting leg and the second supporting leg are arranged in a splayed shape below the wheel lifting plate in the front-back direction. The upper end of the first supporting leg is rotatably connected with the wheel lifting plate, a supporting roller is arranged at the lower end of the first supporting leg, and the first supporting arm is connected with the wheel lifting plate and the first supporting leg to support the wheel lifting plate; the upper end of the second supporting leg is rotatably connected with the wheel lifting plate, a supporting roller is arranged at the lower end of the second supporting leg, and the second supporting arm is connected with the wheel lifting plate and the second supporting leg so as to support the wheel lifting plate. The lifting device not only has a lifting and supporting function, but also is movable, and can lift up a faulty wheel so as to conveniently transfer a faulty field bridge.
