Muab tso ua ke los ntawm txoj kev ua haujlwm yog raws li nram no:
Kev sib haum xeeb ntawm ib qho hlua khi ib qho hlua khi tau muab faib ua ib qho nruas thiab ob chav nruas raws li tus naj npawb ntawm cov nruas: 1 tib qho kev sib dhos, feem ntau yog ib qho chaw sib txuas. Ib kawg ntawm cov hlua hlau yog tsau rau ntawm cov lus, thiab lwm qhov kawg yog txuas nrog lub thawv rau ntawm lub log saum nruab ntug; Thaum lub suab tig, cov hlua hlau hlau yog qhov mob los yog tso tawm rau hauv lub dav hlau nrawm los tsav lub tshem thiab txos ntawm lub thawv nqa. 2 Ob tog nruas ho rhais rau ob chav nqus ntiv tes (Daim Duab 1). Ob txoj hlua hlau xau yog txhua qhov chaw nyob rau ntawm lub suab, thiab feem ntau yog coj los ntawm cov saum toj no thiab hauv qab ntawm cov lus. Thaum lub suab tig, ib lub thawv nqa tuaj thiab ntim lwm lub thawv. Winding hom hoist raws li cov duab ntawm lub nruas yog muab faib ua kev sib npaug thiab lub cev tsis sib haum sib tw ob qho tib si. Lub nruas ntawm txoj kab uas sib npaug yog yooj yim hauv cov qauv, yooj yim los tsim thiab tsis muaj nqi, thiab nws yog siv dav. Thaum sib sib zog nqus zoo yog hoist, lub torque yog heev unbalanced vim loj variation ntawm qhov ntev ntawm cov hlau rope rau ob sab. Ntxov adopters ntawm cov kabmob tsis paub meej-cov kab (cylindrical conical reels) yog tam sim no siv los sib npaug cov hlua tia.
Mine hoist
Lub ntsiab ntu ntawm cov cua daj cua dub yog cov hlua, caj dab, cov kabmob loj, cov hlua khawm hloov, tshem tawm, qhov qhia tau qis thiab nres (Daim duab 2). Cov reels thiab cov ntsiab lus tseem ceeb ntawm ob lub paj ho muaj npe hu ua cov chaw ruaj ruaj, thiab cov uas txuas nrog lub taub hau loj ntawm txoj hlua khawm qhib hu ua active reels. Cov kab hlau uas siv hauv Suav yog 2 ~ 5m. Raws li qhov tob ntawm kuv lub thiab ntau lawm, qhov ntev thiab txoj kab uas hla txoj hlua hlau nce kom haum. Raws li ib tug tshwm sim, lub cheeb thiab dav ntawm lub reel kuj nce, yog li nws tsis haum rau tob zoo lifting.
Mine hoist Multi-rope winding hoist hoist nyob rau hauv kev khiav dej num ntawm ultra-sib sib zog nqus dej, txoj kev hlua tail hlua ntev hloov zoo heev, nyom hlua hlua rau ntawm cov kev sib txuas ntawm txoj kev ntxhov siab, cuam tshuam lub neej ntawm cov hlua hlau; cov hlua khi hlua kuj yog ib qho yooj yim rau kev sib tw hauv qhov dej cawv thiab ua haujlwm tsis zoo. Thaum xaus rau xyoo 1950, tus neeg Blair yog tus tsim Blair tsim ib qhov kev sib tw uas muaj ntau hom kab nrib qaum (tseem hu ua Breyer type hoist) nrog rau qhov siab ntawm 1580-2349m thiab ib tug nqi nce ntawm 10-20t. .
