Ukukhetha i-handrail efanele ye-escalator akukhona nje ukubukeka—kuthinta ngqo ukuphepha, ukuqina, kanye nezindleko zokusebenza zesikhathi eside. Kwabochwepheshe be-elevator kanye ne-escalator, ukuqonda imingcele yokusebenza ebalulekile kusiza ukuqinisekisa ukuthi i-handrail ihambisana nezidingo zemishini kanye nezimo zokusetshenziswa.
I. Izinto Ezibalulekile Zokukhetha
I-handrail efanelekile ye-escalator kufanele ihlangabezane nalezi zimfuneko ezilandelayo eziyinhloko:
Ukuqina: Ukumelana nokuqhekeka, ukuklwebheka, nokuguga
Ukusebenza Kokungqubuzana: I-coefficient eqinile ukuqinisekisa ukunyakaza okuhambisanayo nezinyathelo
Ukumelana Nemvelo: Amandla okumelana nokushisa, umswakama, kanye nokuchayeka kwe-UV
Ukuhambisana: Kufanelekela izinhlobo ezahlukene ze-escalator kanye nezinhlelo zokushayela
Umjikelezo Wokulungisa: Impilo yesevisi ende inciphisa imvamisa yokushintsha kanye nesikhathi sokungasebenzi
II. Amapharamitha Obuchwepheshe Abalulekile
Uma kuhlolwa izibambo, kufanele kubhekwe ngokucophelela lezi zimiso ezilandelayo:
| Ipharamitha | Ibanga Elijwayelekile | Incazelo |
| Amandla Okudonsa | ≥ 25 MPa | Inquma ukumelana nokunwebeka kanye nokuguquguquka |
| Ukwelula Ngesikhathi Sokuphumula | ≥ 300% | Kubonisa ukuguquguquka nokumelana nokuqhekeka |
| Ubulukhuni (Ogwini A) | 65–75 | Kuthinta umuzwa wokubamba kanye nokumelana nokuguguleka |
| I-Coefficient of Friction | 0.3–0.6 | Iqinisekisa ukuvumelanisa nesivinini sesinyathelo |
| Izinga Lokushisa Lokusebenza | -20°C kuya ku-+60°C | Kufanelekela izindawo zangaphakathi nezingaphandle kancane |
| Ukumelana Nokugqoka | ≤ 120 mm³ | Inani eliphansi libonisa ukumelana okungcono kokuguguleka |
| Ukumelana ne-UV | ≥ amahora angu-500 (akukho ukuqhekeka) | Kubalulekile kuma-escalator angaphandle |
| Impilo Yesevisi | Iminyaka emi-3–5 (ejwayelekile) | Kuncike ekusetshenzisweni kaningi kanye nendawo okuyo |
II. Ukwakheka Kwesakhiwo
I-handrail ye-escalator esezingeni eliphezulu ngokuvamile yenziwa ngezendlalelo eziningi:
| Isendlalelo | Izinto | Umsebenzi |
| Isendlalelo Sangaphandle | Irabha / i-TPU | Inikeza ukubamba, ukumelana nokuguguleka, kanye nokubukeka |
| Isendlalelo Sokuqinisa | Izintambo zensimbi/indwangu | Iqinisekisa amandla okuqina kanye nokuqina kobukhulu |
| Isendlalelo Sangaphakathi | Indwangu + irabha | Kunciphisa ukungqubuzana ngemivimbo yokuqondisa |
IV. Ukufanisa nezinhlelo ze-Escalator
Izinhlobo ezahlukene ze-escalator zingaba nezidingo ezithile zobukhulu be-handrail kanye nokusebenza. Uma ukhetha, cabanga ngalokhu:
Ukuhambisana kobubanzi be-handrail kanye nobukhulu
Uhlobo lwesistimu yokushayela (isondo lokushayisana / idrayivu yochungechunge)
Ukunemba kokuvumelanisa isivinini
Indlela yokufaka kanye nohlobo lwejoyinti
Kumaphrojekthi okuthuthukisa, qinisekisa njalo imininingwane yokuqala noma ufake amamodeli alinganayo noma athuthukisiwe.
V. Amazinga Okuhlola Ukusebenza
Abahlinzeki abathembekile banikeza izibambo ezihlangabezana nezindinganiso zokuhlola zomhlaba wonke:
| Into Yokuhlola | Okujwayelekile | Isidingo |
| Ukuhlolwa Kokumelana Nokuqhekeka | Izindinganiso ze-ISO / EN | Akukho mifantu ngemva kokuzigoba okuphindaphindiwe |
| Ukuhlolwa Kokukhathala | ≥ imijikelezo engu-100,000 | Akukho ukwehluleka kwesakhiwo |
| Amandla Okunamathela | ≥ 4 N/mm | Ukubopha okuqinile phakathi kwezingqimba |
| Ukumelana Nomlilo | I-EN115 / ISO | Ihlangabezana nemithetho yokuphepha ye-escalator |
VI. Izindleko vs. Inani Lomjikelezo Wokuphila
Nakuba izibambo ezibiza kancane zinganciphisa izindleko zokuqala, zivame ukuphumela ku:
Ukushintsha njalo
Ukwanda komsebenzi wokulungisa
Ingozi ephezulu yesikhathi sokuphumula
I-handrail esebenza kahle kakhulu enokuqina okude inikeza okungconoinani eliphelele lomjikelezo wokuphila, ikakhulukazi ezindaweni ezinabantu abaningi njengezitolo ezinkulu, iziteshi zesitimela, kanye nezikhumulo zezindiza.
VII. Isixazululo Esinconyiwe
Kumaphrojekthi adinga ukuqina okuthuthukisiwe kanye nokuncipha kwemvamisa yokugcinwa, kunconywa ikhambi lezinga eliphezulu:
Ibhande Lesandla Le-Escalator Le-FUJI — Ukuqina okukhulu ngokusetshenziswa okuphindwe izikhathi ezingu-200,000 ngaphandle kokuqhekeka
Uma kuqhathaniswa nemikhiqizo ejwayelekile (ngokuvamile imijikelezo eyi-100,000), lokhu kwandisa kakhulu impilo yesevisi, okwenza kube kuhle kakhulu ekusetshenzisweni kwemithwalo ephezulu.
Ukukhetha i-handrail efanele ye-escalator kudinga ibhalansi yokusebenza kwemishini, ukuzivumelanisa nezimo zemvelo, kanye nokusebenza kahle kwezindleko zesikhathi eside. Ngokugxila kumapharamitha alinganiswayo kanye nezindinganiso zokuhlola eziqinisekisiwe, ungaqinisekisa ukusebenza okuthembekile kanye nokuphepha kwabagibeli okuthuthukisiwe.
