Kev tiv thaiv ntawm ib qho hlau pulley tsuas yog muab kev tiv thaiv thaum lub sij hawm thauj mus los (ntau tshaj ob lub hlis).Nws yuav tsum tau muab sau tseg tias yog lubkhaws cia ntawm cov hlua hlaumuaj cov xwm txheej zoo, cov hlua hlau hlua tuaj yeem khaws cia rau lub sijhawm ntev. Yog hais tias cov hlua hlau yuav tsum tau muab khaws cia rau ntawm cov hlua hlau rub lub sijhawm ntev, cov xwm txheej hauv qab no yuav tsum tau lav:
1. Nws yuav tsum tau muab khaws cia rau hauv cov khoom pov thawj noo noo, plua plav pov thawj thiab lwm yam kev mob ib puag ncig, thiab cov khoom ntim nws tus kheej yuav tsum tsim nyog rau kev khaws cia ntev (warehouse, steel khoom tiv thaiv, thiab lwm yam). Nyob rau hauv txhua rooj plaub, txoj hlua hlau rub yuav tsum tau muab tso rau hauv kab rov tav.
2. Tsis txhob cuam tshuam rau qhov kub thiab txias ib puag ncig;
3. Nyob rau hauv cov huab cua kub, rau oiled hlau ropes, cov hlau hlua pulley yuav tsum dov ib nrab ib tug tig txhua ob lub hlis los tiv thaiv cov roj los ntawm dripping los yog lub zos tsub zuj zuj, uas ua rau uneven roj cov ntsiab lus nyob rau hauv cov hlau hlua;
4. Kev saib xyuas tshwj xeeb yuav tsum tau them rau kev tiv thaiv tag nrho cov khoom tiv thaiv los ntawm cov chaw tsim khoom. Thaum pib lossis xaus ntawm kev khaws cov hlua hlau, qhov xwm txheej ntawm cov hlua hlau rub yuav tsum raug tshuaj xyuas thiab cov txiaj ntsig tshuaj xyuas yuav tsum raug cim;
5. Khaws daim ntawv teev npe thiab daim ntawv pov thawj zoo ntawm cov hlua hlau rub kom paub cov hlua hlau. Daim ntawv teev npe thiab daim ntawv pov thawj zoo yog muab los ntawm tus neeg muag khoom, thiab ntau yam ntsiab lus ntawm steel hlau hlua tsim yuav tsum tau qhia;
6. Thaum lub sij hawm khaws cov hlua khi, lawv yuav tsum tau muab tso rau ntawm ib qho hlua khi kom tsim nyog kom muaj qhov chaw tsim nyog ntawm cov hlua hlau thiab hauv av, thiab kom tsis txhob muaj kev sib cuag ncaj qha ntawm cov hlua hlau thiab hauv av.
