摘要：
A crane has an elevation structure foldable at its intermediate portion, a rope extended along the structure and a rope support for supporting the rope. When the structure is folded and elevated, the rope support is moved to and held at a position near the point of folding of the structure. After the completion of straightening of the structure, the rope support is held at a position adjacent to the extreme end of the structure. A rope supporting apparatus for realizing this method includes an arrangement for mounting the rope support for movement along the structure, and a shifting driving mechanism mounted on the rope support and adapted to drive the rope support along the length of the structure.
