CA 2441968

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.

L'invention concerne un dispositif de grue à tour comprenant une corbeille (16) qui supporte une grue à tour et qui prend assise dans une zone délimitée par les colonnes verticales (22) d'un bâtiment en construction. La corbeille et la grue à tour reposent sur des saillies de support (28) fixées aux colonnes verticales. Du fait que les charges latérale et verticale sont essentiellement réparties sur les colonnes verticales plutôt qu'horizontalement, il n'est pas nécessaire de renforcer les barres horizontales, les planchers ou toute autre partie de la structure de bâtiment, ce qui entraîne une économie substantielle sur les coûts.
