PROBLEM TO BE SOLVED: To lift or lower an asymmetrical heavy object in which the center of gravity and geometrical center do not coincide with each other while supporting it stably and horizontally. SOLUTION: The weight W of a ceiling main body is divided by the total number N of fulcrums to obtain the initial value Finiti of the reference bearing power Frefi. The deviation between the initial value Finiti and the reference bearing power Frefi is set to ΔFi, and the reference bearing power Frefi is expressed by the equation added with the deviation ΔFi to the initial value Finiti. The load equilibrium equation in the Z-axis direction and the moment equilibrium equation around the X-axis and Y-axis are generated for each fulcrum, and ΔFi is calculated from these equilibrium equations to obtain the reference value Frefi. |
