Hookup attitude control manner of buckling edition and suspender null of buckling

摘要

PURPOSE:To easily carry out the suspension attitude changing work for a curved plate by setting suspension points at apexes of a supposed rectangle which passes through the center of gravity of the curved plate, fixing a connecting tool, connecting both the edges of each wire with the corresponding connecting tool, keeping the center of gravity interposed, and suspending the curved plate. CONSTITUTION:Suspension points A - D are set so as to be positioned at the apexes of a supposed rectangle S whose center of gravity coincides with that of a segment P, and the attitude of the suspended segment P can be changed freely. Accordingly, when the segment P which is suspended in a horizontal attitude is moved manually if necessary, pulleys 5 and 5 revolve in correspondence with the moving direction, and the pulley installation members 4 and 4 turn for a beam member 2. Further, the lower members 4b and 4b of the pulley installation members 4 and 4 revolve for the upper members 4a and 4a, and each direction of the pulleys 5 and 5 changes, and further the beam member 2 turns for a hook engagement member 3. The attitude of the segment P is changed smoothly and in stable manners by the revolution and turn, and the change to the longitudinal attitude or installation attitude can be carried out easily.
