The utility model particularly relates to an in put formula automatic balance hoisting point structure, characterized by: it is including connecting base and leading truck, connect the bottom centralauthorities trompil of base, two sets of connection otic placodes are set up to the symmetry on the top surface of connection base, the both sides wallboard of leading truck horizontal direction through connect on the base two sets of connections otic placodes with be connected the base and sell the hub connection, be equipped with the hoisting point connecting seat on the both sides wallboard ofthe vertical orientation of leading truck, whole in put formula automatic balance hoisting point structure passes through to connect the round pin hub connection between base and the leading truck, realizes the swing at left right direction, through the round pin hub connection between leading truck and the external hoisting point, and balanced about the fore -and -aft direction realization is swung, is realized, front and back balance. Because the hoisting point connecting seat is unified to be set up in the leading truck, the distance between the center pin that both and double round mill shortens, so arm of force moment principle is very little to the influence that the double round mills, makes the double round of putting formula hoisting point structure in the adoption originally millto change and utilize its gravity and realize that the nature is perpendicular.
