Txoj kev loj hlob ntawm domestic thoob lub log stackers thiab reclaimers tau pib dhau los ntawm peb theem. Nyob rau xyoo 1960 thiab 1970, Tuam Tshoj pib tsim cov thoob lub log me me thiab cov khoom siv rov qab. Cov qauv zoo yog 3025, 8030, thiab lwm yam, nrog rau cov zog ntawm 300t / h thiab 800t / h, thiab gyration radii ntawm 25m thiab 30m feem. Xyoo 1980s thiab 1990s yog theem thib ob ntawm kev tsim cov thoob lub log stackers thiab reclaimers. Cov thoob loj-loj stacker-reclaimers tau maj mam tau txais hauv cov khoom siv tshiab uas tsim los ntawm cov chaw cia khoom xws li steel mills thiab fais fab nroj tsuag rau stacking thiab transshipment ntawm tej ntaub ntawv. Cov zis nce mus txog 2000t / h, thiab lub vojvoog tig mus txog 40m. Kev txwv los ntawm cov xwm txheej hauv tsev nyob rau lub sijhawm ntawd, kev tsim kho ntawm cov khoom siv thauj khoom thauj khoom no feem ntau yog tsim los ntawm kev koom tes lossis kev xa tawm tag nrho, thiab txawm tias tag nrho cov khoom siv thauj khoom loj tau raug xa los ntawm txawv teb chaws. Tom qab xyoo 2000, lub thoob thoob lub log stackers thiab reclaimers tau tsim rau theem tshiab. Txog tam sim no, cov tuam txhab lag luam hauv tsev muaj peev xwm tsim thiab tsim khoom ntawm 300 ~ 6000t / h muaj peev xwm ntau lawm thiab 25 ~ 60m tig vojvoog thoob lub log stacker thiab reclaimer series khoom. Nyob rau theem no, cov chaw tsim khoom txawv teb chaws tseem nyob ntawm qee qhov sib koom, tab sis cov tuam txhab tsim khoom hauv tsev tau paub txog cov cuab yeej technology thiab cov peev txheej tsim khoom, thiab tau tuav txoj haujlwm tseem ceeb hauv kev lag luam hauv tsev los ntawm kev tsim txiaj ntawm kev pabcuam thiab tus nqi zoo, thiab maj mam txav mus rau kev lag luam thoob ntiaj teb.
