Raws li ib puag ncig steel txuas saw chaw tsim khoom rau 30 xyoo, peb lub Hoobkas tau nyob nrog thiab ua haujlwm rau lub sijhawm tseem ceeb ntawm Suav cov saw hlau ua kev lag luam evolution catering rau mining (coal mine tshwj xeeb), hnyav nqa, thiab kev lag luam conveying yuav tsum nyob rau hauv siab zog puag ncig. steel txuas chains. Peb tsis txhob tso tseg ntawm kev ua tus thawj coj sib txuas txuas cov chaw tsim khoom hauv Suav teb (nrog rau cov khoom txhua xyoo ntau dua 10,000T), tab sis ua raws li kev tsim thiab kev tsim kho tshiab.
