《起重机械监督检验规程》(以下简称《规程》)中要求:塔机安装后,在空载、无风的状态下,塔身轴心线对支承面的侧向垂直度≤4/1000。1 2种常见的测量方法简介1.1《规程》中的检验方法将标尺分别水平固定在臂架铰点附近和基础节(或最高附着点)的塔身上,其中心位于塔身中心线上,臂架转到其纵向轴线与塔身的一个截面中心线重合的位置,分别在X、Y轴的2个方向上用经纬仪
Crane Supervision and Inspection Procedures (hereinafter referred to as the “Rules”) requirements: the tower crane installed in the no-load, no wind conditions, the tower axis of the bearing surface perpendicularity ≤ 4/1000 .1 Introduction to the 2 Common Methods of Measurement 1.1 Test Methods in the Procedures The scales are to be fixed horizontally on the tower near the hinge point of the boom and on the base section (or the highest attachment point) with its center on the center line of the tower, Boom to its longitudinal axis and tower cross section of the centerline of a coincidence position, respectively, in the X, Y axis of the two directions with theodolite
