1. Xaiv cov khoom siv log: ua ntej xav txog qhov loj ntawm txoj kev nto, cov teeb meem, cov khoom seem ntawm qhov chaw siv (xws li cov ntaub ntawv hlau, roj), ib puag ncig tej yam kev mob (xws li qhov kub thiab txias, qhov kub thiab txias) thiab qhov hnyav. tias cov log tuaj yeem nqa tau. cov xwm txheej los txiav txim siab xaiv cov khoom siv log tsim nyog. Piv txwv li, cov log roj hmab tsis tiv taus cov kua qaub, roj thiab tshuaj lom neeg, thaum lub log super polyurethane, lub log muaj zog polyurethane, nylon log, steel log thiab siab kub log yog tsim rau ntau qhov chaw tshwj xeeb.
2. Xam cov khoom hnyav: txhawm rau xam cov peev txheej uas yuav tsum tau muaj los ntawm ntau cov casters, nws yog ib qho tsim nyog yuav tsum paub txog tus kheej qhov hnyav ntawm cov khoom siv thauj khoom, qhov siab tshaj plaws load thiab pes tsawg lub log thiab casters siv. Qhov yuav tsum tau muaj peev xwm ntawm ib lub log lossis caster yog xam raws li hauv qab no:
T=(E plus Z)/M × N:
---T=Qhov yuav tsum tau muaj qhov hnyav ntawm ib lub log lossis caster;
---E=tus kheej qhov hnyav ntawm cov khoom thauj;
---Z= siab tshaj load;
---M=tus naj npawb ntawm ib lub log thiab casters siv;
---N=yam kev nyab xeeb (kwv yees 1.3-1.5).
3. Txiav txim siab qhov loj ntawm lub log txoj kab uas hla: Feem ntau, qhov loj ntawm lub log txoj kab uas hla, nws yooj yim dua rau thawb, lub peev xwm thauj khoom ntau dua, thiab muaj peev xwm tiv thaiv hauv av kom tsis txhob puas. Kev xaiv ntawm lub log txoj kab uas hla yuav tsum xub xav txog qhov hnyav ntawm lub load thiab qhov pib thrust ntawm lub tsheb nyob rau hauv lub load. txiav txim siab.
4. Kev xaiv ntawm cov khoom siv log nyuaj thiab mos: Feem ntau cov log muaj xws li nylon log, super polyurethane log, siab zog polyurethane log, siab zog dag roj hmab log, hlau log, thiab inflatable log. Super polyurethane log thiab lub zog siab polyurethane log tuaj yeem ua tau raws li koj cov kev cai tuav txawm tias lawv khiav hauv tsev lossis sab nraum zoov; Lub zog hluav taws xob hluavtaws roj hmab tuaj yeem siv rau hauv tsev so, cov khoom siv kho mob, cov plag tsev, cov plag tsev ntoo, cov nplais hauv pem teb, thiab lwm yam. Nws yuav tsum tau tsav tsheb hauv av tsis muaj suab nrov thiab ntsiag to thaum taug kev; nylon log thiab hlau log yog haum rau cov chaw uas tsis sib xws hauv av los yog hlau filings thiab lwm yam khoom nyob rau hauv av; thaum lub log inflatable yog haum rau lub sijhawm nrog lub teeb load thiab mos thiab tsis sib xws ntawm txoj kev.
5. Kev sib hloov hloov tau yooj yim: qhov loj dua ntawm ib lub log, qhov ntau zog-txuag nws yog tig, cov menyuam bearing tuaj yeem nqa hnyav dua, thiab qhov kev tiv thaiv thaum sib hloov yog loj dua: lub log ib leeg yog nruab nrog cov khoom zoo (cov kabmob steel) pob bearings, uas tuaj yeem nqa hnyav dua, kev sib hloov yog sib dua, hloov tau thiab ntsiag to.
6. Qhov kub thiab txias: qhov txias txias thiab kub siab ua rau muaj kev cuam tshuam zoo rau cov casters. Polyurethane log tuaj yeem tig tau yooj yim thiab ywj pheej ntawm qhov kub qis ntawm rho tawm 45 degree, thiab cov log kub resistant tuaj yeem tig tau yooj yim ntawm qhov kub ntawm 275 degree.
Kev saib xyuas tshwj xeeb: Vim tias 3 cov ntsiab lus txiav txim siab lub dav hlau, thaum tus naj npawb ntawm cov casters siv yog 4, lub peev xwm thauj khoom yuav tsum raug xam raws li 3.
