| Abstract: | After several years＇ usage, walking mechanism of the QLY25B tyre crane had troubles frequently, especially some gears of the reducer casing of walking mechanism worn heavily, which has to be transformed. This paper states the pr/nciple of the reducer casing of the walking mechanim, analyzes the reasons of the trouble and puts forward improving measures. After transform, the reducer casing of walking mechanism runs well. The trouble rate of the walking mechanism decreases obviously. |
