Ama-cranes amabhuloho, aziwa nangokuthi ama-cranes angaphezulu, asetshenziswa kakhulu ezimbonini ezahlukahlukene ukuphakamisa nokuhambisa imithwalo esindayo.Amagama amabili abalulekile ahlotshaniswa nama-cranes amabhuloho ubude be-headroom nokuphakama kokuphakamisa.
Ukuphakama kwe-headroom kwe-crane yebhuloho kubhekisela ebangeni eliphakathi kwephansi nephansi le-beam yebhuloho le-crane.Lesi silinganiso sibalulekile njengoba sinquma inani lesikhala esidingekayo ekusebenzeni kwe-crane, kucatshangelwa noma yiziphi izithiyo, njengamapayipi, amapayipi, ama-trusses ophahleni noma izinto zokukhanyisa, ezingase zithiye ukuhamba kwawo.Ukuphakama kwe-headroom kuvame ukwenziwa ngendlela oyifisayo, futhi amaklayenti angacacisa izidingo zawo ngokuya ngezingqinamba zesikhala sendawo yawo.
Ngakolunye uhlangothi, ukuphakama kwe-crane yebhuloho kubhekisela ebangeni i-crane engakwazi ukuphakamisa umthwalo, likalwa ukusuka phansi kuya endaweni ephakeme kakhulu yokuphakamisa.Lobu bude buwukucatshangelwa okubalulekile, ikakhulukazi lapho kudluliselwa izinto zokusebenza noma imikhiqizo ezindaweni ezinamaleveli amaningi, lapho ibanga eliphakeme kakhulu lokuphakamisa i-crane lidlala indima ebalulekile ekunqumeni inani lephansi okufanele ilifti lihambe.
Kubalulekile ukuqonda umehluko phakathi kokuphakama kwe-headroom nokuphakama kokuphakamisaama-cranes ebhuloho, njengoba kungasiza ekukhetheni nasekuklameni okokusebenza okufanela kangcono indawo yokusebenza yekhasimende kanye nezimfuneko.
Ukuphakama kokuphakama kudlala indima ebalulekile ekunqumeni umthamo we-crane ukuthutha impahla endaweni ethile.Ukuphakama kokuphakama kwe-crane kufanele kukhethwe ngokucophelela, futhi kuya ngohlobo lomthwalo kanye nokuma nobukhulu besikhungo.Kubalulekile ukwenza ukukhetha okufanele ngenkathi ucabangela ukuphakama kokuphakamisa, njengoba kungase kuthinte ukusebenza kahle nokukhiqiza kwe-crane.
Sengiphetha, uma kukhulunywa ngama-cranes amabhuloho, ukuphakama kwe-headroom nokuphakama kokuphakama yizici ezimbili ezibalulekile okufanele zicatshangelwe.Ukuhlola kahle nokunquma ngalezi zici kungasiza ekuthuthukiseni ukusebenza kwe-crane yebhuloho, ukunciphisa isikhathi sokuphumula, nokuqinisekisa ukuphepha endaweni.
