发明名称 Method and arrangement for staying climb rods for co-operation with so-called climbing jacks
摘要 A method of staying climb rods for co-operation with so-called climbing jacks by utilizing masts, preferably lattice masts, each of which climb rods is capable to carry vertical forces transferred via associated climbing jacks, while horizontal forces acting on the climb rod are transferred to the staying mast. The method comprises the steps of supporting the staying mast pivotally on a footing permitting the mast to pivot slightly in any direction, and attaching the climb rod slidably to the staying mast so as to render possible relative movements in the vertical direction between the rod and the mast. The invention also relates to an arrangement for staying climb rods in accordance with the method set forth.
