塔机标准节制作工装简介邓莉（四川省建筑科学研究院成都）塔式起重机的塔身标准节是重要部件，需用量大，精度要求高，互换性也应当好。组装到独立高度后还要保证塔身轴心线相对于支承面的安装垂直度小于４／１０００。因此制造标准节时应有设计合理的工装。工装最基本的... Tower crane standard section made tooling Brief introduction Deng Li (Sichuan Academy of Building Research Chengdu) Tower crane tower standard section is an important component, requiring large quantities, high precision, interchangeability should also be good. Assembled to an independent height, but also to ensure that the tower axis relative to the bearing surface of the mounting perpendicularity is less than 4/1000. Therefore, the standard section should be designed to make reasonable tooling. Tooling the most basic ...
