Ho khetha sehatla sa lifti tse phahameng se nepahetseng ha se taba feela ea ponahalo—se ama ka ho toba polokeho, ho tšoarella le litšenyehelo tsa ts'ebetso ea nako e telele. Bakeng sa litsebi tsa lifti le lifti tse phahameng, ho utloisisa liparamente tsa bohlokoa tsa ts'ebetso ho thusa ho netefatsa hore sehatla se lumellana le litlhoko tsa lisebelisoa le maemo a ts'ebeliso.
I. Lintlha tsa Khetho ea Bohlokoa
Sehatsetsi sa escalator se tšoanelehang se lokela ho fihlela litlhoko tse latelang tsa mantlha:
Ho tšoarella: Ho hanyetsa ho petsoha, ho taboha le ho tsofala
Tshebetso ea Khohlano: Koefficient e tsitsitseng ho netefatsa motsamao o tsamaellanang le mehato
Khanyetso ea Tikoloho: Bokhoni ba ho mamella mocheso, mongobo le mahlaseli a kotsi a UV
Ho lumellana: E loketse mefuta e fapaneng ea li-escalator le litsamaiso tsa ho khanna
Potoloho ea Tlhokomelo: Bophelo ba tšebeletso e telele bo fokotsa makhetlo a ho nkela sebaka le nako ea ho se sebetse
II. Liparamente tsa Bohlokoa tsa Tekheniki
Ha ho hlahlojoa li-handrails, liparamente tse latelang li lokela ho hlahlojoa ka hloko:
| Paramethara | Mefuta e Tloaelehileng | Tlhaloso |
| Matla a tšepe | ≥ 25 MPa | E khetholla ho hanyetsa ho otlolla le ho fetoha ha sebopeho |
| Ho Lelefatsa Nako ea Phomolo | ≥ 300% | E bontša ho tenyetseha le ho hanyetsa mapetso |
| Bothata (Lebopong la A) | 65–75 | E ama maikutlo a ho tshwara le ho hanyetsa ho tsofala |
| Khokahano ea Khohlano | 0.3–0.6 | E netefatsa ho hokahana le lebelo la mohato |
| Mocheso o sebetsang | -20°C ho isa ho +60°C | E loketse tikoloho ea ka tlung le ea kantle hanyane |
| Ho hanyetsa ho apara | ≤ 120 mm³ | Boleng bo tlase bo bontša khanyetso e betere ea ho khohlela |
| Khanyetso ea UV | ≥ lihora tse 500 (ha ho petsohe) | Bohlokoa bakeng sa li-escalator tsa kantle |
| Bophelo ba Tšebeletso | Lilemo tse 3–5 (tse tloaelehileng) | Ho itshetlehile ka kgafetsa ya tshebediso le tikoloho |
II. Sebopeho sa Sebopeho
Sehatsetsi sa escalator sa boleng bo holimo hangata se etsoa ka mekhahlelo e mengata:
| Lera | Thepa | Mosebetsi |
| Lera le ka Ntle | Rabara / TPU | E fana ka ho tšoara, ho hanyetsa ho tsofala, le ponahalo |
| Lera la Matlafatso | Lithapo tsa tšepe / lesela | E netefatsa matla a ho tsikinyeha le botsitso ba litekanyo |
| Lera la ka Hare | Lesela + rabara | E fokotsa khohlano ka lireile tse tataisang |
IV. Ho bapisa le Mekhoa ea Li-Escalator
Mefuta e fapaneng ea li-escalator e ka ba le litlhoko tse khethehileng bakeng sa litekanyo tsa lithaele le ts'ebetso. Ha u khetha, nahana ka:
Bophara ba letsoho le botenya bo tsamaellanang
Mofuta oa sistimi ea ho khanna (lebili la khohlano / drive ea ketane)
Ho nepahala ha ho hokahanya lebelo
Mokhoa oa ho kenya le mofuta oa manonyeletso
Bakeng sa merero ea ntlafatso, kamehla netefatsa litlhaloso tsa mantlha kapa u li nkele sebaka ka mehlala e lekanang kapa e ntlafalitsoeng.
V. Maemo a Teko ea Tshebetso
Bafepedi ba tšepahalang ba fana ka li-handrails tse fihlelang maemo a liteko tsa machaba:
| Ntho ea Teko | E tloaelehileng | Tlhokahalo |
| Teko ea Khanyetso ea Maqhubu | Maemo a ISO / EN | Ha ho mapetso ka mor'a ho kobeha khafetsa |
| Teko ea Mokhathala | ≥ lipotoloho tse 100,000 | Ha ho na ho hloleha ha sebopeho |
| Matla a ho khomarela | ≥ 4 N/mm | Kamano e matla pakeng tsa mekhahlelo |
| Khanyetso ea Mollo | EN115 / ISO | E fihlela melao ea polokeho ea li-escalator |
VI. Boleng ba Litšenyehelo khahlanong le ba Potoloho ea Bophelo
Leha li-handrails tse theko e tlase li ka fokotsa litšenyehelo tsa pele, hangata li fella ka:
Ho nkeloa sebaka khafetsa
Mosebetsi o eketsehileng oa tlhokomelo
Kotsi e phahameng ea nako ea phomolo
Sehatsetsi se sebetsang hantle se nang le botsitso bo bolelele se fana ka betereboleng bohle ba potoloho ea bophelo, haholo-holo libakeng tse nang le sephethephethe se seholo joalo ka mabenkele a maholo, liteishene tsa metro le boema-fofane.
VII. Tharollo e Khothaletsoang
Bakeng sa merero e hlokang ho tšoarella ho eketsehileng le ho fokotseha ha makhetlo a tlhokomelo, ho kgothaletswa tharollo ya maemo a hodimo:
Lebanta la Handrail la FUJI Escalator — Ho tšoarella haholo ka makhetlo a 200,000 a tšebeliso e se nang mapetso
Ha ho bapisoa le lihlahisoa tse tloaelehileng (hangata lipotoloho tse 100,000), sena se atolosa bophelo ba tšebeletso haholo, se etsa hore e be se loketseng lits'ebetso tse nang le mojaro o moholo.
Ho khetha sehatsetsi se nepahetseng sa li-escalator ho hloka tekano ea ts'ebetso ea mechini, ho ikamahanya le tikoloho, le ts'ebeliso e ntle ea litšenyehelo tsa nako e telele. Ka ho tsepamisa maikutlo ho liparamente tse ka lekanngoang le maemo a liteko a netefalitsoeng, u ka netefatsa ts'ebetso e tšepahalang le polokeho e ntlafetseng ea bapalami.
