The invention provides trackless portal crane equipment capable of stably lifting. The trackless portal crane equipment capable of stably lifting comprises a cross beam, a sliding rail is arranged onthe cross beam, an electric hoist is connected to the sliding rail in a sliding manner, and the trackless portal crane equipment is characterized in that vertical upper supporting frames are fixed onthe two sides of the bottom of the cross beam, the cross sections of the upper supporting frames are in an I shape, lower supporting frames are slidably connected into grooves in the two sides of theupper supporting frames, the cross sections of the lower supporting frames are rectangular, and the two lower supporting frames slidably connected to the upper supporting frames are jointly and fixedly connected to a base. a driving mechanism used for driving the upper supporting frames to move up and down is arranged at the position, located between the two lower supporting frames, of the base. The trackless portal crane equipment capable of stably lifting has the beneficial effects that lifting of the cross beam can be achieved, the application range is widened, the lifting efficiency of a gantry crane can be improved, and the stability of the cross beam in the lifting process can be guaranteed.
