The four-link gantry crane can lift the rated lifting weight throughout the whole process. Some of them switch the lifting gearbox in the second half, and can lift a larger tonnage after changing the transmission ratio. In addition, when the amplitude changes, the horizontal height of the hoisted object does not change. The lifting curve of the single-arm gantry crane is a straight line in which the amplitude is inversely proportional to the lifting weight. The larger the amplitude, the smaller the lifting weight. In addition, the horizontal height of the hoisted object changes with the amplitude, and the lifting does not move. The larger the amplitude, the lower the object, and when the amplitude is small, the object is high.
