Design and Optimization of Special-Purpose Tower Crane for Large Tower of Transmission Line
Abstract: Transmission line tower has the features of tower material weight, tower height high, difficulty in installation, high accuracy, complicated installation, complex construction environment and grave risk. Comprehensive consideration of weight, maneuverability, construction efficiency, site occu-pancy and other factors, to carry out professional design, the large special tower crane used for the large tower of transmission line is successfully developed. The special tower crane adopts the advanced technological scheme such as single jib, the top rotary structure, the assembling founda-tion, the balanced weight system, the chip standard section, the under jacking mechanism and the self-removal function. The special tower crane has the advantages of high efficiency, good safety, small space and personnel, etc. The special tower crane meets the need of the construction of the special high pressure engineering tower, and has been widely used in the construction of UHV power network.
