一种新颖的液压起道器在黄岩县液压机械厂问世。四月一日,由北京铁路局和浙江省机械厅联合主持通过了产品鉴定。我同铁路运输的16000营业公里的繁忙重载线路中,年运量超过了3000万吨总重,有的已超过1亿吨,其轨道基础口趋重型化,钢轨从43、50公斤/米发展到60、70、75公斤/米,迄今全路已有5000公里线路铺设了这种重型钢轨。为适应重轨线路维修养护作业需要,黄岩县液压机械厂与北京铁路局工务处线务科经二年时间努力,研制成功了SYQD—15型手动液压起道器,最大起道量147千牛吨(15吨),最大起升高度120毫米,空载效率大于5.6毫米/次,手柄(长为1米时)操作力小于440牛顿,手柄摆动角度小于60°,质量小于26千克。试产
A new type of hydraulic lifter came out in Huangyan Hydraulic Machinery Factory. April 1, the Beijing Railway Administration and Zhejiang Provincial Machinery Office jointly presided over the product identification. Of the 16,000 kilometers of busy heavy lines that I carry with rail transport, the annual traffic volume exceeds 30 million tons of gross weight, and some of them have exceeded 100 million tons. The orbital base ports tend to be heavy, with rails from 43,50 kg / m With a total area of 60,70,75 kg / m, 5,000 heavy lines have been laid so far across the country. In order to meet the needs of heavy rail line maintenance and maintenance operations, hydraulic machinery plant in Huangyan County and the Beijing Railway Administration Branch of the line of work after two years of hard work, the successful development of the SYQD-15-type manual hydraulic lifting device, the maximum starting volume of 147 kN (15 tons), the maximum lifting height of 120 mm, no-load efficiency greater than 5.6 mm / time, the handle (length of 1 meter) operating force of less than 440 Newtons, the handle swing angle of less than 60 °, mass less than 26 kg.
