用“水准仪吊钩吊尺法”测量桥式起重机主梁拱度

Measuring Girder's Camber of Bridge Crane by Cable Sling and Height Gauge with Water Level

简介了笔者用水准仪结合吊钩挂放吊尺测量桥式起重机主梁拱度的探索过程,详细介绍了此法的具体操作步骤,并对此法在测拱过程中的诸多技术性问题及测量结果的准确度进行了比较深入的讨论与论证。最后寄望此法能在桥式起重机的拱度检测工作中得以全面推广普及。

This article introduces the author how to use cable sling, height gauge together with water level to measure girder's camber of bridge crane, and expatiates the operation process in detail. It also discusses and demonstrates thoroughly about the technical issues and the precision of measure results in the process by this method to measure girder's camber. Eventually, the author hopes that this measuring method can be applied to the measuring operation across-the-board.
