    Abstract: A rotary tower crane has a tower constructed from uniformly sized sections which can be arranged to provide a tower of small or large cross section, as required. The tower sections can be aligned in a single, vertical column to provide a tower having a narrow cross section, or a plurality of sections can be joined horizontally to form sections of enlarged cross section, which are then vertically aligned to provide a tower having an enlarged cross section.

    Abstract: A rotary tower crane having a tower which can be extended step-wise by adding a section between the boom supporting segment and segments of the supporting structure is provided with a host and crab mechanism for adding or removing a section adjacent to the boom without the use of another crane. The tower is provided with a movable inner tower member slidably disposed in the upper tower segment. The inner tower member has transverse members adapted to be retracted so they will pass bracing members on the tower and to expand to a point where they will support the inner member on the brace members when immediately above the brace members.

    Abstract translation: 具有塔架的旋转式塔式起重机设置有主机和螃蟹机构，该塔架可以在悬臂支撑段和支撑结构的段之间添加一段来逐步延伸，该主机和螃蟹机构用于在没有使用的情况下添加或移除与起重臂相邻的部分 的另一台起重机。 该塔具有可滑动地设置在上部塔段中的可移动内塔架构件。 内塔构件具有适于缩回的横向构件，使得它们将在塔上通过支撑构件并且扩展到在支架构件正上方时它们将支撑支撑构件上的内部构件的点。
