Cost-effective analysis between truck crane and gantry crane in concrete pipe installation;

Through the study and anlysis on the technology of the concrete construction of both the bottom slabs and piers for Caoejiang Sluice,a Beiley crane with large span is elaborately designed for the concrete placement intensity of 35～40 m3/h,which successfully realizes the application of Beiley crane to the concrete construction in water control project.

Application of homemade gantry crane with high-low legs in the construction of great-span bridges;

Design and checking calculation method to gantry crane foundation of a beam prefabricate plant;

The article discusses a practical and economic construction method to lay down the flow pipe with a special de- signed hanger and the gantry crane at the bottom of the cloaca,when the construction working face is too limited to use the crane to lay down the large-diameter pipes directly during laying down the construction.
