UKULUNGISELELA ISIVIVINYO SOMKHIQIZO WOKUPHEPHA: PHUME ISIVIVINYO SAKHO SOKUPHEPHA NGESIFUNDAZWE

Uhlelo lokusebenza lokulungiselela ukuhlolwa kuphela olwakhelwe izivivinyo zelayisensi yesifundazwe se-lifti. Izivivinyo zakho zihlola i-ASME A17.1 Safety Code, izidingo zikagesi ze-NEC Article 620, amazinga e-OSHA, kanye nezinhlelo zemishini. Lolu hlelo lokusebenza luhlanganisa konke.

UKUQHATHANISWA KWE-TRACTION VS HYDRAULIC

I-Traction lifti: izintambo zensimbi kanye ne-sheave eqhutshwa yimoto kagesi. Ilungele ukudonsa ngesivinini esisheshayo, ayinagiya lokuphakama okuphezulu. Isisindo esiphikisayo sinciphisa umthwalo wemoto. Akukho mkhawulo wejubane osebenzayo.

I-Hydraulic lifti: ipompo, ijeki, kanye namafutha kuphakamisa imoto. Izilawuli zamandla adonsela phansi zehlisa. Izinhlobo: ukusebenza ngqo emhlabathini, okungenamigodi, i-hydraulic enezintambo. Ukuhamba okuphezulu cishe ngamafidi angu-50.

Amadivayisi okuphepha aqhathaniswa eceleni kufaka phakathi i-governor kanye ne-safeties (traction) vs i-valve yokwehlisa kanye ne-valve yokuqhuma (hydraulic), izinhlobo ze-buffer, kanye nezikhawu zokuhlola ze-ASME A17.1.

IKHODI YOKUBHEKISA YEKHODI YE-ASME A17.1

Umgodi: ubuncane bokujula okungamamitha angu-2, ukukhanya phezulu kwesitebhisi, inkinobho yokumisa ngaphakathi kwamamitha angu-2, isitebhisi siyadingeka uma umgodi udlula amasentimitha angu-35. Igumbi lomshini: ubuncane bokukhanda okungamamitha angu-7, izinga lokushisa elingu-50 kuya ku-90 degrees F, inkinobho yokunqamula lapho imishini ibona khona. Indlela yokuphakamisa: ukwakhiwa okumelana nomlilo, akukho zinto ezivuthayo. Izikhawu zokuhlola: ukuhlolwa okuvamile minyaka yonke, ukuhlolwa kokuphepha kanye nokuhlolwa kombusi njalo eminyakeni emi-5.

UMHLAHLANDLELA WEDIVAYISI LOKUPHEPHA

Umbusi: i-centrifugal, isebenza ngesivinini esikhulu, ikhubaza ukuphepha kwemoto. Ukuphepha kwemoto: izinti zokuqondisa zokubamba. Ishesha ngesivinini esiphansi, iyaqhubeka ngesivinini esiphezulu. I-Buffer: uwoyela (ukudonsa) noma intwasahlobo (i-hydraulic). Ukukhiya umnyango: kuvimbela ukunyakaza ngaphandle kokuthi umnyango we-hoistway ukhiyiwe. Iswishi yokumisa i-Pit: iphula isekethe yokulawula.

IMIBUZO YOKUZIQHEKEZA EYI-1,000+

IMBONO KAGESI NE-NEC (30%): Amandla esigaba sesithathu, inkolelo-mbono yemoto, izifunda zokulawula imoto, Isigaba se-NEC 620, ukumisa nokubopha, izifunda zamagatsha, ama-GFCI emakamelweni omshini.

Umthombo: I-NFPA 70 Ikhodi Kagesi Kazwelonke (i-NEC) — https://www.nfpa.org/codes-and-standards/nfpa-70-standard-development/70

IKHODI YE-ASME A17.1 (25%): Izidingo ze-Pit, igumbi lomshini, kanye ne-hoistway, indawo ebiyelwe imoto, izikhawu zokuhlola nokuhlola, ukusebenza okuphuthumayo, ukufinyeleleka.

IZINHLELO ZOMKHIQIZO (25%): Izingxenye zokudonsa (i-sheave, izintambo zocingo, isisindo esiphikisayo, imigqa yokuqondisa), izingxenye ze-hydraulic (ipompo, i-jack, i-valve yokulawula, isilinda), izinhlelo zamabhuleki, ukuthambisa.

AMADIVAYISI OKUPHEPHA (10%): Izilungiselelo zikahulumeni kanye nesivinini esingaphezu kwesilinganiso, izinhlobo zokuphepha, izinhlobo ze-buffer, i-interlock yomnyango, izikhawu zokuhlola.

I-OSHA NE-SAFETY (10%): I-OSHA 1926 Subpart R, i-lockout kanye ne-tagout, ukuvikelwa kokuwa ezindaweni zokuphakama, isikhala esivalekile semigodi.

Umthombo: I-OSHA 1926 Subpart R — https://www.osha.gov/laws-regs/regulations/standardnumber/1926/1926SubpartR

Yonke imibuzo ifaka incazelo eningiliziwe ngesigaba se-ASME A17.1 kanye nezinkomba zesihloko se-NEC.

MAHHALA: Imibuzo emi-5 ngosuku, ukuqhathaniswa kwe-traction vs hydraulic, ukubuka konke kwedivayisi yokuphepha. Akukho akhawunti edingekayo.

NYANGA ZONKE ($9.99): Imibuzo engenamkhawulo, wonke amathuluzi, isivivinyo samahhala sezinsuku ezi-3.
NYAKA ZONKE ($24.99): Yonga ngaphezu kwamaphesenti angama-75. Inani elihle kakhulu.
I-LIFETIME ($49.99): Inkokhelo eyodwa. Ukufinyelela unomphela.

ISITHEMBISO SOKUDLULA: isilinganiso esingu-80%, ukubhalisa okusebenzayo izinyanga ezi-3, akukadluli: izinyanga ezi-4 ezinwetshiwe mahhala. voltexam.com/pass-promise

Ayihlobene ne-NEIEP, i-IUEC, i-ASME, noma yiliphi ibhodi lelayisensi ye-elevator likahulumeni. Izinkomba zekhodi zenzelwe ukulungiselela ukuhlolwa kwezemfundo kuphela.
