The analysis showed that one rope length small changes will cause larger changes in the hoisting system in four ropes. Through a lot of calculations and analysis to come to a reasonable degree of change of the length of the rope and construction accuracy combined. This method can provide some experiences to the construction and fabrication of the steel member of the project.Keywords: solder ball; flexible enhance overall; connection point
