COMPOUND BALANCE AND HEAVY OBJECT CARRYING IN METHOD USING COMPOUND BALANCE

PURPOSE:To provide a compound balance and a heavy object carrying in method using the compound balance, eliminating a large scaled jack up frame structure and a roller drawing device or a turn table device and the like for carrying in a large sized heavy object, and capable of shortening an installation construction process of the large sized heavy object. CONSTITUTION:A method comprises overhead cranes 16, 17 set up in a ceiling of a building to be movable in a prescribed direction, main balance 1 with both ends fixedly supported to these overhead cranes 16, 17, connecting bar 3 fixed so as to be suspended in an almost central position of this main balance 1, intermediate balance 4 rotatably supported to the center of this connecting bar 3 and a subbalance 7 supported respectively to both ends of this intermediate balance 4 to suspend an objective heavy object which must be carried into the building. Further, a tilt absorbing means (pin 2, radial bearing, thrust bearing), absorbing a tilt of the intemediate balance 4 due to an unbalanced load, is provided in the connecting bar 3 of the main balance 1 and the intermediate balance 4.
