- 摘要:
- 文章论述了起重机恒抬吊力吊装法的依据、实施方式和产生偏差的评估与纠正,提出了促进该吊装技术应用的建议。该吊装方法能始终保持各吊点抬吊力恒定,并且通过三吊点和重心构成的四点共面设置解决了抬吊力的分配问题,方法简单可靠。
This paper discusses the basis, the implementation mode, the deviation assessment and correction of the new hoisting technique with constant uplift force by erecting crane as well as the approach promoting the technique. This technique can keep the constant uplift forces at each hoisting point, and solve the uplift force distribution problem by means of four points coplanarity mode in which the three hoisting points plus one gravity center are allocated within one plane. The new hoisting technique is simple and reliable.2010,1(1): 76-77 收稿日期：2009-5-6分类号：TH213作者简介：林汉丁(1936-),男,福建福州人,教授级高工,退休前一直从事工业设备安装技术工作.参考文献：
