| Abstract: | In order to eliminates accident of colliding the dam foundation by the bucket during the back running of the reclaimer arm and prevent the damage of the bucket, a reform of the reclaimer control system has been carried out. This paper introduces the measures taken in the reform, such as adding the limit spacing on the site, perfecting the protection function for back running by differential contact technology. It has got good results. |
