◉ Ileli yekhebulaindawo yokubeka. Njengoko igama libonisa, yibhulorho exhasa iintambo okanye iingcingo, ekwabizwa ngokuba yi-ladder rack kuba imilo yayo ifana neleli.Ilelii-rack inesakhiwo esilula, umthamo oqinileyo wokuthwala umthwalo, uluhlu olukhulu lwezicelo, kwaye kulula ukuyifaka kwaye kulula ukuyisebenzisa. Ukongeza kwiintambo ezixhasayo, iirekhi zeleli zingasetyenziselwa ukuxhasa imibhobho, njengemibhobho yomlilo, imibhobho yokufudumeza, imibhobho yegesi yendalo, imibhobho yezixhobo zeekhemikhali njalo njalo. Izicelo ezahlukeneyo zihambelana neemodeli zeemveliso ezahlukeneyo. Kwaye ummandla ngamnye okanye ilizwe ngalinye ngokweemfuno zendawo yendawo yangaphandle baye baphuhlisa imigangatho yeemveliso ezahlukeneyo, ngoko ke iindidi zeemodeli zemveliso ezibizwa ngokuba ziimodeli ezahlukeneyo. Kodwa umkhombandlela jikelele wesakhiwo esiphambili kunye nenkangeleko imalunga nokufana, inokwahlulwa ibe zizakhiwo ezibini eziphambili, njengoko kubonisiwe ngezantsi:
◉Njengoko unokubona kumfanekiso ongentla, isakhelo seleli eqhelekileyo senziwe ngeentsimbi ezisecaleni kunye neziphambano.Imilinganiselo yayo ephambili yi-H kunye ne-W, okanye ubude kunye nobubanzi. Le milinganiselo mibini imisela uluhlu lokusetyenziswa kwale mveliso; Ixabiso elikhulu le-H, ubukhulu bobubanzi bentambo enokuthi ithwalwe; Ixabiso le-W elikhulu, inani elikhulu leentambo ezinokuthwala.Kwaye umahluko phakathi koHlobo Ⅰ kunye noHlobo Ⅱ kulo mfanekiso ungasentla ziindlela ezahlukeneyo zokufakela kunye nenkangeleko eyahlukileyo. Ngokwemfuno yomthengi, inkxalabo ephambili yomthengi ixabiso le-H kunye ne-W, kunye nobukhulu bezinto eziphathekayo T, kuba ezi xabiso zihambelana ngqo namandla kunye neendleko zemveliso. Ubude bemveliso abuyona ingxaki ephambili, kuba ubude beprojekthi kunye nokusetyenziswa kwemfuno enxulumene nemfuno, masithi: iprojekthi idinga i-30,000 yeemitha zeemveliso, ubude beemitha ezi-3 1, ngoko kufuneka siyenze. ukuvelisa ngaphezulu kwe-10,000. Kucingelwa ukuba umthengi uziva 3 yeemitha elide kakhulu ukufaka, okanye hayi lula ukulayisha ikhabhinethi, kufuneka itshintshwe ibe 2.8 yeemitha a, ke kuthi nje inani lemveliso ibe 10,715 okanye ngaphezulu, ukuze eqhelekileyo-20-unyawo isikhongozeli isikhongozeli. inokulayishwa ngaphezulu kwemigangatho emibini, kukho ubutyebi bendawo encinci yokufaka izincedisi. Iindleko zemveliso ziya kuba notshintsho oluncinci, kuba ubuninzi buyanyuka, inani elihambelanayo lezinto ezincedisayo liya kwanda, umthengi kufuneka anyuse iindleko zokuthengwa kwezixhobo. Nangona kunjalo, xa kuthelekiswa noku, iindleko zokuthutha ziphantsi kakhulu, kwaye le ndleko iyonke ingancitshiswa kancinane.
◉Le theyibhile ilandelayo ibonisa amaxabiso ahambelanayo ka-H kunye no-W weileliizakhelo:
W\H | 50 | 80 | 100 | 125 | 150 | 200 | 250 | 300 |

◉Ngokutsho kohlalutyo lokusetyenziswa kweemfuno zemveliso, xa ixabiso le-H kunye ne-W linyuka, indawo yokufakela ngaphakathi kwi-ladder rack iya kuba nkulu. Ngokuqhelekileyo, iingcingo ezingaphakathi kwi-ladder rack zinokuzaliswa ngokuthe ngqo. Kuyimfuneko ukushiya isithuba esaneleyo phakathi komtya ngamnye ukuququzelela ukutshatyalaliswa kobushushu kunye nokunciphisa impembelelo efanayo. Uninzi lwabathengi bethu benze izibalo kwaye bahlalutya ngaphambi kokukhetha iirekhi zeleli, ukuze kuqinisekiswe ukhetho lweemodeli zeleli rack. Nangona kunjalo, asibandakanyi ukuba abanye abathengi abayazi kakuhle, kwaye baya kusibuza imithetho okanye iindlela ekukhetheni. Ke ngoko, abathengi kufuneka banikele ingqalelo kula manqaku alandelayo ekukhetheni i-ladder rack:
1, indawo yofakelo. Indawo yokufakela ithintela ngokuthe ngqo umda ophezulu wokukhethwa kwemodeli yemveliso, ayinakudlula indawo yofakelo lomthengi.
2, iimfuno zokusingqongileyo. Ubume bemveliso bumisela imveliso kumbhobho ukushiya ubungakanani bendawo yokupholisa kunye neemfuno zokubonakala. Okufanayo kwakhona kumisela ukhetho lwemodeli yemveliso.
3, umbhobho cross-icandelo. Umbhobho we-cross-section sisigqibo esithe ngqo sokukhetha umda ophantsi wemodeli yemveliso. Ayinakuba ncinane kunobungakanani bombhobho onqamlezayo wecandelo.
Qonda ezi mfuno zintathu zingasentla. Inokuqinisekisa ubungakanani bokugqibela kunye nokumila kwemveliso.
