Ukukhetha i-handrail efanelekileyo ye-escalator akupheleli nje ekujongeni—ichaphazela ngqo ukhuseleko, ukuqina, kunye neendleko zokusebenza kwexesha elide. Kwiingcali ze-elevator kunye ne-escalator, ukuqonda iiparameter eziphambili zokusebenza kunceda ukuqinisekisa ukuba i-handrail iyahambelana neemfuno zezixhobo kunye neemeko zokusetyenziswa.
I. Izinto ezibalulekileyo zokukhetha
I-handrail ye-escalator efanelekileyo kufuneka ihlangabezane neemfuno eziphambili ezilandelayo:
Ukuqina: Ukuxhathisa ukuqhekeka, ukukrweleka, kunye nokwaluphala
Ukusebenza kweFriction: I-coefficient ezinzileyo ukuqinisekisa intshukumo ehambelanayo namanyathelo
Ukumelana nokusingqongileyo: Ukukwazi ukumelana nobushushu, ukufuma, kunye nokuvezwa yi-UV
Ukuhambelana: Ifanelekile kwiimpawu ezahlukeneyo zee-escalator kunye neenkqubo zokuqhuba
Umjikelo WokugcinwaUbomi benkonzo ende kunciphisa ukuphindaphinda kunye nexesha lokungasebenzi
II. Iiparameter zobuGcisa ezibalulekileyo
Xa kuvavanywa ii-handrails, ezi parameter zilandelayo kufuneka zijongwe ngononophelo:
| Ipharamitha | Uluhlu oluqhelekileyo | Inkcazo |
| Tensile strength | ≥ 25 MPa | Inquma ukumelana nokuzolula kunye nokuguqulwa |
| Ukwandiswa ngexesha lokuphumla | ≥ 300% | Ibonisa ukuguquguquka kunye nokumelana nokuqhekeka |
| Ubunzima (uLwandle A) | 65–75 | Ichaphazela indlela yokubamba kunye nokumelana nokuguguleka |
| I-Coefficient of Friction | 0.3–0.6 | Iqinisekisa ukuvumelanisa nesantya senyathelo |
| Ubushushu bokusebenza | -20°C ukuya ku +60°C | Ifanelekile kwiindawo zangaphakathi nangaphandle |
| Ukumelana nokunxiba | ≤ 120 mm³ | Ixabiso eliphantsi libonisa ukumelana okungcono kokukrweleka |
| Ukumelana ne-UV | ≥ iiyure ezingama-500 (akukho kuqhekeka) | Kubalulekile kwii-escalators zangaphandle |
| Ubomi beNkonzo | Iminyaka emi-3–5 (eqhelekileyo) | Kuxhomekeke kwinani lokusetyenziswa kunye nendawo engqongileyo |
II. Ulwakhiwo lwesakhiwo
I-handrail ye-escalator esemgangathweni ophezulu idla ngokwenziwa ngee-layers ezininzi:
| Umaleko | Izinto eziphathekayo | Umsebenzi |
| Umaleko ongaphandle | Irabha / iTPU | Inika ukubamba, ukumelana nokuguguleka, kunye nenkangeleko |
| Umaleko Wokuqinisa | Iintambo zentsimbi/ilaphu | Iqinisekisa amandla okuxinana kunye nozinzo olulinganayo |
| Umaleko wangaphakathi | Ilaphu + irabha | Inciphisa ukungqubana ngeereyili ezikhokelayo |
IV. Ukufanisa neeNkqubo ze-Escalator
Iimpawu ezahlukeneyo zee-escalator zinokuba neemfuno ezithile zobungakanani kunye nokusebenza kwe-handrail. Xa ukhetha, cinga:
Ukuhambelana kobubanzi be-handrail kunye nobukhulu
Uhlobo lwenkqubo yokuqhuba (ivili lokukhuhlana / idrayivu yetsheyini)
Ukuchaneka kokuvumelanisa isantya
Indlela yokufaka kunye nohlobo lwejoyinti
Kwiiprojekthi zokuphucula umgangatho, soloko uqinisekisa iinkcukacha zokuqala okanye uzitshintshe ngeemodeli ezifanayo okanye eziphuculweyo.
V. Imigangatho yoVavanyo lokuSebenza
Ababoneleli abathembekileyo banikezela ngee-handrails ezihlangabezana nemigangatho yovavanyo lwamazwe ngamazwe:
| Into yoVavanyo | Umgangatho | Imfuneko |
| Uvavanyo lokuxhathisa ukuqhekeka | Imigangatho ye-ISO / EN | Akukho ziqhekeko emva kokuzithulula ngokuphindaphindiweyo |
| Uvavanyo lokudinwa | ≥ iibhayisekile ezili-100,000 | Akukho kusilela kwesakhiwo |
| Amandla okuncamathela | ≥ 4 N/mm | Ukubopha okuqinileyo phakathi kweengqimba |
| Ukumelana nomlilo | EN115 / ISO | Ihlangabezana nemigaqo yokhuseleko lwee-escalator |
VI. Ixabiso leendleko xa kuthelekiswa nexabiso lomjikelo wobomi
Nangona ii-handrails ezingabizi kakhulu zinokunciphisa iindleko zokuqala, zihlala zibangela oku kulandelayo:
Ukutshintshwa rhoqo
Ukwanda kwabasebenzi bokulungisa
Umngcipheko ophezulu wokungasebenzi
I-handrail esebenza kakuhle enokuqina okude inika ngconoixabiso lilonke lomjikelo wobomi, ingakumbi kwiindawo ezinabantu abaninzi ezinje ngeevenkile ezinkulu, izitishi zemetro, kunye nezikhululo zeenqwelo-moya.
VII. Isisombululo Esicetyiswayo
Kwiiprojekthi ezifuna ukuqina okuphuculweyo kunye nokugcinwa okuncitshisiweyo rhoqo, kucetyiswa isisombululo esikumgangatho ophezulu:
Ibhanti yesandla se-FUJI Escalator — Ihlala ixesha elide kakhulu kwaye isetyenziswa ngokuphindwe kayi-200,000 ngaphandle kokuqhekeka
Xa kuthelekiswa neemveliso eziqhelekileyo (ngesiqhelo ii-cycles ezili-100,000), oku kwandisa ubomi benkonzo, nto leyo eyenza ukuba ilungele ukusetyenziswa kwemithwalo ephezulu.
Ukukhetha i-handrail efanelekileyo ye-escalator kufuna ulungelelwaniso lokusebenza koomatshini, ukulungelelaniswa nokusingqongileyo, kunye nokusebenza kakuhle kweendleko ixesha elide. Ngokugxila kwiiparamitha ezinokulinganiswa kunye nemigangatho yovavanyo eqinisekisiweyo, unokuqinisekisa ukusebenza okuthembekileyo kunye nokhuseleko oluphuculweyo lwabakhweli.
