《机械工22000年产品振兴目标研究》是国家经委批准的重大技术开发项目,气腿式和内燃凿岩机2000年振兴目标研究是这个项目的两项子课题。该课题在大量收集国内外有关资料和广泛征询国内各方面专家意见的基础上,采用“多指标加权评分”的方法,将国产YT27/28型和美国乔伊(JOY)公司加拿大分公司的AL60M型气腿式凿岩机,国产YN30A型和瑞典伯瑞玛(Berema)公司的Pionjar(先锋)120型手持式内燃凿岩机分别进行了综合的评价对比。对我国凿岩机的水平、关键技术、发展趋势、市场需求和出口前景等
The “Research on the Promotion of Productivity of the 22000 Mechanical Products” is a major technology development project approved by the State Economic Commission. The research on the revitalization goals of the gas leg type and the internal combustion rock drill in 2000 are two sub-topics of this project. Based on the massive collection of relevant domestic and foreign data and extensive consultation with domestic experts in various fields, this topic adopts a “multi-indicator weighted scoring” method and will use the domestically produced YT27/28 model and the American company JOY company’s AL60M. The gas leg type rock drill, the domestically-produced YN30A type, and the Swedish Pionjar (pioneer) 120 hand-held internal-combustion rock drill have been comprehensively evaluated and compared. The level, key technology, development trend, market demand and export prospects of China’s rock drills
