Cov khoom siv Yeej Nyuaj yog cov thoob uas muaj zog hnyav uas siv cov hinged mechanism rau daus thiab nqa cov ntaub ntawv xoob. Cov taw no yog qhov tseem ceeb rau cov khoom siv thauj khoom zoo li cov khoom siv thee, ore, grain, xuab zeb hauv kev tsim kho, kev tsim khoom, thiab kev lag luam khoom muag. Ntau hom crushs, xws li clamshly crushs, yog tsim rau cov ntaub ntawv tshwj xeeb, nrog cov khoom loj, thiab yooj yim cov khoom ntws.
HYDRAULIC GRAVs tau siv dav hauv kev lag luam uas xav tau kev tuav cov khoom siv ntau:
Chaw nres nkoj thiab Docks: Chaw thau khoom thiab tsis muaj cov khoom thauj khoom loj xws li cov thee, ore, grain, thiab chiv.
Cov khoom siv hloov khoom yards: hlau thiab hlau zeb ore thiab Coke cia vajntxwv; Lub hwj chim cog thee.
Kev tsim kho cov engineering: kos thiab hloov chaw xuab zeb, gravel, av, thiab crushed pob zeb.
Kev tiv thaiv thiab kev tiv thaiv ib puag ncig: thawb seem ntawm cov hlau thiab cov ntaub qhwv; tuav thiab txheeb cov dej khov kho cov khib nyiab; slude tshem tawm los ntawm cov dej phwj tuaj kho cov nroj tsuag.
Tsuas: Chaw thau khoom ore ua ke nrog cov kab hluav taws xob nrog excavators.
Cov Khoom Taw Qhia Kev Thauj Khoom: Tshem cov ntaub ntawv ntxiv los ntawm cov tsheb thauj khoom zoo.
Grab Thoob Thoob:
Tus naj npawb ntawm lub puab tsaig Flaps:
Muab ob npaug rau cov khaub ncaws hnav khaub ncaws thoob: veras ntau tshaj, haum rau feem ntau cov ntaub ntawv.
Ntau hom lapse tuav thoob (piv txwv li, 5-6 lobes): siv rau brob cov pob zeb, cov pob zeb loj
Clamshell lauj kaub thoob: Ob lub lobes yog plhaub-puab, muab kev sib sau zoo heev thaum muab cov khoom siv granular xws li cov khoom pov thawj ua pov thawj yog qhov siab.
Tsim qauv qauv:
Lub teeb yuag: siv rau cov khoom muaj nuj nqis tsawg.
Hnyav-Ua Haujlwm: Refleksful cov qauv, siv rau ores, thiab lwm yam.
Ntxiv-hnyav-duty / seem steel lis dej thoob: ua los ntawm cov hlau tshwj xeeb nrog kev txhawb nqa cov hniav, siv rau kev ua haujlwm hnyav.
Cov cuab yeej hydraulic yog cov cuab yeej tseem ceeb hauv cov khoom siv niaj hnub sib xyaw ua ke, tus cwj pwm los ntawm kev ua haujlwm siab, lub zog, thiab kev txawj ntse. Kev xaiv kom zoo thiab sib txuam nrog tus tswv tsev ua haujlwm, ua haujlwm sib xyaw ua ke nrog kev ua haujlwm zoo, kev nyab xeeb, thiab kev ua haujlwm tsis zoo ntawm kev thauj khoom thiab thauj khoom. Thaum xaiv ib tug cab, nws yog qhov tseem ceeb kom sib txuas lus kom huv nrog cov kws tshaj lij lossis cov chaw muag khoom hais txog cov haujlwm ua haujlwm tshwj xeeb. Weihua pawg yog ib tug coj kev tsim khoom lag luam nyob hauv Suav teb, muab cov neeg siv khoom lag luam zoo nyob rau xyoo 1988. Peb zoo siab tos txais koj cov lus nug txog cov khoom lag luam.
