The invention discloses a base-reinforced tower crane, and belongs to the technical field of tower cranes. According to the key points of the technical scheme, four vertical frames used for supportingthe overall structure of the tower crane, and a base which is arranged at the bottom ends of the four vertical frames and used for stably installing the four vertical frames; the base comprises fourlocating plates; the four locating plates are vertically arranged, and jointly form a #-shaped structure; L-shaped corners are formed at the four corners of the #-shaped structure, and the four vertical frames are welded at the four L-shaped corners separately; a bottom plate is welded at the bottoms of the four locating plates, and is perpendicular to the locating plates, and the four locating plates are located in the middle of the bottom plate; and the bottom ends of the four vertical frames are welded with the bottom plate. According to the base-reinforced tower crane, the limiting effectof the base on the vertical frames is very good, so that the vertical frames are higher in stability.

    本发明公开了一种基座加强型塔式起重机,属于塔式起重机技术领域,其技术方案要点是,包括用于支撑其整体结构的四根立架以及安装在四根立架底端用于稳固安装四根立架的基座,基座包括有四块定位板,四块定位板均竖立设置并共同构成“井”字型结构,该“井”字型结构的四角处均形成有L型拐角,四根立架分别焊接在该四个L型拐角处,四块定位板的底部焊接有一块底板,底板与定位板垂直,且四块定位板位于底板的中部,四根立架的底端与底板焊接。该种基座加强型塔式起重机的基座对立架的限位效果十分好,从而使立架具有更好的稳固性。
