The single girder gantry crane is simple structure, easy installation and manufacture, and small dead weight. Compared with the double girder gantry crane, the overall stiffness is weaker. Double beam gantry crane is large carrying capacity, large span and good overall stability, but on same working level, double girder gantry crane has much heavire dead weight than single girder gantry crane, and the cost is higher.
