我厂自1978年起,在30吨桥式行车、15吨门座吊车等大型起重设备安装及修理中,开始应用J2-JD型激光经纬仪确定部分机件的水平和中心线位置,用以代替传统的玻璃连通器水准管、圆规、角尺及重锤等划线工具,大大提高了大型起重设备机件测量和定位工效,并提高安装的几何精度。
Since 1978, we have started to apply the J2-JD laser theodolite to determine the horizontal and centerline positions of some mechanical parts in the installation and repair of large-scale lifting equipment such as 30-ton overhead traveling vehicles and 15-ton overhead traveling cranes. Instead of the traditional glass connector leveling pipe, compasses, angle ruler and heavy hammer and other marking tools, it greatly improves the measurement and positioning work efficiency of large lifting equipment and improves the geometric precision of installation.
