Ukukhetha i-girder eyodwa ye-girhead crane kuhilela ukucabanga ngezinto eziningana ukuqinisekisa ukuthi i-crane ihlangabezana nezidingo zakho ezithile. Nazi ezinye izinyathelo ezibalulekile zokukusiza kwinqubo yokukhetha:
Nquma izidingo zomthwalo:
- Khomba isisindo esiphezulu somthwalo udinga ukusiphakamisa nokuhambisa.
- Cabanga ubukhulu nokwakheka komthwalo.
- Nquma uma kukhona izidingo ezikhethekile ezihlobene nomthwalo, njengezinto ezintekenteke noma eziyingozi.
Hlola indlela ye-Span ne-Hook:
- Kala ibanga phakathi kwezinhlaka zokusekelwa noma amakholomu lapho kuzofakwa khona i-crane (span).
- Nquma indlela edingekayo ye-hook, okuyi-mpo yebanga umthwalo udinga ukuhamba.
- Cabanga nganoma yiziphi izithiyo noma izithiyo kwindawo yokusebenza engathinta ukunyakaza kwe-crane.
Cabanga ngomjikelezo wokusebenza:
- Nquma imvamisa nesikhathi sokusetshenziswa kwe-crane. Lokhu kuzosiza ekutholeni umjikelezo womsebenzi noma isigaba somsebenzi esidingekayo kwi-crane.
- Amakilasi we-Duty Cycle aqala kusuka ku-Light-Duty (ukusetshenziswa okungajwayelekile) kuya emsebenzini osindayo (ukusetshenziswa okuqhubekayo).
Linganisa imvelo:
- Hlola izimo zemvelo lapho i-crane izosebenza khona, njengokushisa, umswakama, izinto ezilimazayo, noma i-aplosmances eqhumayo.
- Khetha izinto ezifanele nezici zokuqinisekisa ukuthi i-crane ingamelana nezimo zemvelo.
Ukucatshangelwa Kwezokuphepha:
- Qinisekisa ukuthi i-crane ihambisana namazinga nemigomo esebenzayo yokuphepha.
- Cabanga ngezinto zokuphepha ezifana nokuvikela ngokweqile, izinkinobho zokumisa eziphuthumayo, ukushintshwa komkhawulo, namadivayisi okuphepha ukuvimbela ukushayisana.
Khetha ukucushwa kwe-hoist ne-trolley:
- Khetha umthamo ofanele we-host nesivinini esisuselwa kwizidingo zomthwalo.
- Nquma uma udinga i-trolley yencwajana noma enezimoto yokuhamba okuvundlile eduze komgcini.
Cabanga ngezici ezingeziwe:
- Hlola noma yiziphi izici ezingeziwe ongazidinga, njengokulawula okukude komsakazo, Ukulawulwa kwejubane okuguquguqukayo, noma okunamathiselwe okukhethekile kokuphakamisa.
Thintana nochwepheshe:
- Funa izeluleko kubakhiqizi be-crane, abahlinzeki, noma ochwepheshe abanolwazi abanganikeza umhlahlandlela ngokusekelwe kubuchwepheshe babo.
Ngokucabanga ngalezi zinto kanye nokubonisana nochwepheshe, ungakhetha i-gerder girder overhead ehlangabezana nezidingo zakho zokuphakamisa kanye nokusingathwa kwezinto ezibonakalayo ngenkathi uqinisekisa ukuphepha nokusebenza kahle ekusebenzeni kwakho.
