But regarding needs the frequent hoisting, the work time short situation, like about engine bed work piece, installation work hoisting spare part, in assembly line fixed-point work and so on; Regarding the request quite pinpointing situation, like in the casting under core, gathers box and so on, the general hoisting equipments are not often suitable, the industry manipulator uses in producing from the generatrix in or the sole repetition operation, moreover the cost is high, the general workshop use are at present few. In recent years, appeared one kind of new fixed point hoisting equipment “the balance hung”, was suitable in lifts frequently several dozens to several hundred kilogram work piece fixed points, played the extremely vital role in the industrial production, the structure which the balance hung has been simple, the operation was nimble about, after the crane besides could do rises and falls, could make 360 degree gyroscopic motions in the horizontal plane, only needed gently on rollers, might cause to hang the thing steadily to pause as necessary in the position which cared for to pause, achieved the indifferent equilibrium. This article elaborated the balance hangs the basic principle, and has carried on the analysis and the research to its equilibrium condition and the pole departments balanced metho
