Loaders yog cov khoom siv hauv av siv dav siv hauv kev tsim kho xws li txoj kev, kev tsheb ciav hlau, kev tsim kho, hydropower, chaw nres nkoj, thiab mines. Lawv feem ntau yog siv los shovel tej ntaub ntawv xws li av, xuab zeb, txiv qaub, thiab thee, thiab tseem muaj peev xwm ua lub teeb shoveling ua hauj lwm ntawm ore, tawv av, thiab lwm yam. Los ntawm kev hloov txawv auxiliary ua hauj lwm pab kiag li lawm, bulldozing, lifting, thiab loading thiab unloading. lwm cov ntaub ntawv xws li ntoo kuj tuaj yeem ua tau. Loaders tuaj yeem muab faib ua cov loaders me me, nruab nrab loaders, loj loaders, thiab ntxiv-loj loaders raws li lawv lub zog.
Cov dej ntws ntawm cov loaders yog cov khoom siv raw xws li steel, iav, thiab roj hmab, nrog rau cov khoom xws li cav, log tsheb, thiab rooj zaum; midstream yog tsim thiab muab cov loaders; cov downstream feem ntau yog siv nyob rau hauv txoj kev loj, railways, kev tsim kho, chaw nres nkoj, hydropower, thiab mines.
Hlau yog ib qho ntawm cov khoom siv tseem ceeb rau cov loaders. Nrog rau kev txhim kho tas mus li ntawm kuv lub teb chaws kev lag luam steel, steel ntau lawm kuj tau nce, muab cov khoom raw txaus lav rau kuv lub teb chaws cov khoom tsim khoom.
Kev tsim kho kev lag luam yog ib qho ntawm cov ntawv thov hauv qab ntawm kuv lub teb chaws kev lag luam loader. Nrog rau kev txhim kho tas mus li ntawm kuv lub teb chaws cov infrastructure, vaj tse thiab lwm yam kev lag luam, thaj chaw tsim kho vaj tse nyob rau hauv kev tsim kho kev lag luam kuj tseem nce ntxiv, thiab kev loj hlob ntawm kev thov tau txhawb txoj kev loj hlob tsis tu ncua ntawm kev lag luam.
Nrog rau kev txhim kho txuas ntxiv ntawm kuv lub teb chaws cov vaj tsev, kev tsim vaj tsev, kev tsim hluav taws xob thiab lwm yam kev lag luam hauv xyoo tas los no, qhov kev thov rau cov khoom thauj khoom kuj tseem nce ntxiv. Kev loj hlob ntawm kev thov tau ua rau muaj kev nce ntxiv hauv kev muag khoom ntawm cov khoom thauj khoom hauv kuv lub tebchaws.
