质心可调式重型水平吊具

Heavy centroid-adjustable horizontal sling

介绍了一种自身质心可调的重型水平吊具的结构形式、工作原理、强度计算、试验及使用情况。该吊具首次采用了起吊位置调节和自身质心无级调节的两级组合调节方式,具有操作简便、调节精度高的特点。经过试验验证,能够较好地满足使用要求,为后续同类产品吊具的研制提供了一种新的设计思路。

The paper introduces the structure,operating principle,strength calculation,test and usage of a heavy horizontal sling with adjustable centroid.The sling is the first to combine lifting position adjustment and self stepless centroid adjustment with the advantages of easy operation and high adjusting accuracy.Tests demonstrate that the sling fairly satisfies the requirements and points out a new design idea for the development of similar products in the future.
