我厂在部、局和市有关部门的领导和支持下,于1981年与西德利勃海尔公司签定了“R942”液压挖掘机许可证协议。“R942”是国际上八十年代的新产品,主要特点是恒功率变量系统,先导液压操纵,柴油机和液压元件均为国际先进水平的厂商配套,通用配套件覆盖面大,整机性能完善,作业装置选配达40余件,还可以向系列上下发展。我厂引进“R942”不仅提高了技术水平和管理水平,突破了我国长期以来定量液压系统占主导地位的局面,促进了产品改造和新产品开发,而且对促进我国建筑机械行业的技术发展,对提高基础元器件,发
With the leadership and support of the relevant departments of the ministry, bureau, and city, our factory signed a license agreement for “R942” hydraulic excavator with West De Liebherr in 1981. “R942” is a new product in the 1980s. Its main features are constant power variable system, pilot hydraulic control, diesel engine and hydraulic components are all supported by internationally advanced manufacturers, universal accessories cover a large area, complete machine performance, and operation There are more than 40 devices available for selection, and the series can also be developed from top to bottom. The introduction of “R942” in our factory not only improved the technical level and management level, but also broke through the long-term situation in which China’s quantitative hydraulic system dominated, promoted product transformation and new product development, and promoted the technological development of China’s construction machinery industry.
