0.4米~3靠壁式液压抓岩机,是由长沙矿山研究院、南昌通用机械厂、第八冶金建设公司共同研制成功的竖井掘进装载机械。在竖井掘进时可将爆破后的松散岩渣装入吊桶。该机于74年10月完成样机试制,并进行了地表试验测定检查,75年1～4月在甘肃省金川二矿区完成了井下工业性试验。75年4月份进行技术鉴定。会议认为该样机的研制、试验是成功的,可以定型、批量生产。
0.4 m ~ 3 by the wall hydraulic grabs, by the Changsha Institute of Mining, Nanchang General Machinery Plant, the eighth Metallurgical Construction Company jointly developed a successful shaft boring and loading machinery. In the shaft excavation can blast loose rock residue into the bucket. The prototype was prototyped in October, 74, and ground surface test was carried out. From January to April in 1975, the underground industrial test was completed in Jinchuan No. 2 Mine Area, Gansu Province. 75 years in April for technical appraisal. The meeting that the prototype development, testing is successful, you can stereotypes, mass production.
