A. Khetho ea Ketane
1. Litaba tsa Kereiti:
-G70 (Ketane ea Lipalangoang): Tšebeliso e akaretsang, ho ba bonolo ho e sebelisa.
-G80 (Ketane ea ho Phahamisa):Matla a phahameng, a tloaelehileng bakeng sa ts'ireletso.
-G100:Karolelano e phahameng ka ho fetisisa ea matla ho ea boima (e sebelisoa le lisebelisoa tse lumellanang).
- Kamehla bapisa ketane ea ketane le kereiti ea lisebelisoa.
2. Boholo le WLL:
- Bala kakaretso ea khatello e hlokahalang (ho latela melaoana e kang EN 12195-3 kapa FMCSA).
- Mohlala: Mojaro oa 20,000 lb o hloka khatello ea ≥5,000 lbs ka ketane (ntlha ea polokeho ea 4:1).
- Sebelisa liketane tse nang le khatello e baloang ea WLL ≥ (mohlala, ketane ea 5/16" G80: WLL 4,700 lbs).
B. Khetho ea Lisebelisoa
- Litlamo:
Li-Ratchet Binders: Khatello e nepahetseng, ts'ebetso e sireletsehileng (e loketse meroalo ea bohlokoa).
Li-Lever Binders: Li potlakile, empa li kotsi ea ho khutla kapele (li hloka koetliso).
- Lihokelo/Lihokelo:
Lihokelo tsa ho Tšoara: Hokela lihokelong tsa ketane.
Lihokelo tse Thellang: Tšehetsang lintlheng tse tsitsitseng (mohlala, foreimi ea teraka).
Lihokelo tsa C-Hooks/Clevis: Bakeng sa lihokelo tse khethehileng (mohlala, mahlo a tšepe a koili).
- Lisebelisoa: Litšireletso tsa mathōko, li-monitor tsa khatello ea maikutlo, li-chain.
C. Litlhophiso tse Ikhethang ka Mojaro
- Mechine ea Kaho (mohlala, Mochini oa ho Epa):Liketane tsa G80 (3/8"+) tse nang le li-binder tsa ratchet;Tiisa litsela/mabili + lintlha tsa ho khomarela; thibela motsamao oa ho bina.
- Likhoele tsa Tšepe:Liketane tsa G100 tse nang le li-C-hook kapa li-chock;Sebelisa khoele ea "figure-8" ka har'a leihlo la khoele.
- Libalaka tsa Sebopeho:Liketane tsa G70/G80 tse nang le lepolanka le sirelelitsoeng ho thibela ho thella;Ketane e tšelang likhutlong tse ≥45° bakeng sa botsitso ba lehlakore.
- Liphaephe tsa Konkreite: Lipheletso tsa Chock + liketane holim'a phaephe ka likhutlo tse 30°-60°.
A. Tlhahlobo (Pele/Kamora Tšebeliso e 'Ngoe le e 'Ngoe)
- Lihokelo tsa Ketane:Hana haeba: E otlolohile ho feta ≥3% ea bolelele, mapetso, maqeba a ka holimo ho 10% ea bophara ba khokahano, ho tjheseletsa ha weld, ho bola ho hoholo.
- Lihokelo/Litlamo:Hana haeba: E sothehile, ho buleha ha 'metso ho eketseha ka >15%, ho petsoha, ho hloka li-latch tsa polokeho.
- Litlamo:Hana haeba: Mohele/mmele o kobehileng, di-pawl/di-gear tse tsofetseng, diboutu tse hlephileng, mafome a sa sebetseng hantle.
- Kakaretso:Hlahloba hore na ketane e senyehile libakeng tseo e kopanang le tsona (mohlala, moo ketane e amang mojaro);Netefatsa matšoao a WLL a balehang le litempe tsa sehlopha.
B. Tataiso ea ho Nkela Sebaka
- Ho Nkela Sebaka ka Tsela e Tlamang:Mapetso afe kapa afe a bonahalang, ho lelefala, kapa setempe sa boleng bo holimo ha se balehe;Lihokelo/lithapo tse kobehileng >10° ho tloha sebopehong sa pele;Ho senyeha ha sehokelo sa ketane >15% ea bophara ba pele.
- Tlhokomelo e Thibelang:Lubella li-binder tsa ratchet khoeli le khoeli;Kenya di-binder sebakeng sa tsona dilemo tse ding le tse ding tse 3-5 (esita le haeba di sa senyeha; ho tsofala ha kahare ha ho bonahale);Ho tlohela mosebetsi ka mor'a lilemo tse 5-7 tsa tšebeliso e boima (tlhahlobo ea litokomane).
C. Litokomane
- Boloka litlaleho tse nang le matsatsi, lebitso la mohlahlobi, liphuputso le liketso tse nkiloeng.
