TOWER CRANE DEVICE

摘要

A crane tower device includes a basket (16) that supports a tower crane and sits within a bay formed by the vertical columns (22) of a building under construction. The basket and the tower crane are supported by support stubs (28) that are attached to the vertical columns. Because the lateral and vertical load is principally distributed vertically to the vertical columns rather than horizontally, no reinforcement of the horizontal beams, floors or any other portion of the building structure are needed, which results in substantial cost savings.
