Xa ukhetha iI-crane ephezuluinkqubo yoncedo lwakho, enye yezona zikhetho zibalulekileyo oya kuzenza kukufakela ibhulorho esebenzayo ephezulu okanye ibhulorho ephantsi kwebhulorho. Bobabini bangabentsapho yee-cranes ze-EOT (i-Electric Overhead Traveling cranes) kwaye zisetyenziswa ngokubanzi kuwo wonke amashishini okuphatha izinto eziphathekayo. Nangona kunjalo, ezi nkqubo zimbini ziyahluka kuyilo, umthamo womthwalo, ukusetyenziswa kwendawo, kunye neendleko, okwenza nganye ifaneleke ngakumbi kwizicelo ezithile. Ukuqonda lo mahluko kunokukunceda wenze isigqibo sokuthenga esinolwazi olwandisa ukusebenza kakuhle kunye nokhuseleko kwimisebenzi yakho.
♦ Uyilo kunye noLwakhiwo
A phezulu ibhulorho crane ebalekayoisebenza kwiintsimbi ezigxunyekwe phezu kwemiqadi yendlela yeenqwelo-moya. Olu luyilo luvumela itroli kunye ne-hoist ukuba ibaleke phezu kweebhulorho ezigcina ibhulorho, zibanika ubude bokuphakama obuphezulu kunye nokufikelela lula kulondolozo. Iinkqubo ezisebenzayo eziphezulu zinokwakhiwa njenge-girder enye okanye i-double girder configurations, enikezela ukuguquguquka kwezakhono ezahlukeneyo zomthwalo kunye neemfuno ze-span. Ngenxa yokuba itroli ihleli phezu kwebhulorho, ibonelela ngobude obugqwesileyo bokuhoka, isenza ezi cranes zilungele ukuphakamisa umsebenzi onzima.
Ngokwahlukileyo, iI-crane yebhulorho ephantsiixhonywe kumzantsi weflange yeendlela zeenqwelo-moya. Endaweni yeziporo phezulu, i-hoist kunye netroli zihamba ngaphantsi kwebhanti yebhulorho. Olu luyilo luhlangene kwaye lufanelekile kwiindawo ezinesilingi eziphantsi okanye i-headroom encinci. Ngelixa ngokubanzi ithintela ukuphakama kokuphakama xa kuthelekiswa neenkqubo zokubaleka eziphezulu, i-underhung crane isebenzisa ngokufanelekileyo indawo ethe tye kwaye ihlala ixhaswa sisakhiwo.'s isakhiwo sesilingi, ukunciphisa imfuno yeentsika ezongezelelweyo zenkxaso.
♦Umthamo womthwalo kunye nokuSebenza
I-crane ephezulu eqhuba ibhulorho yindlu yamandla yeEOT craneusapho. Iyakwazi ukusingatha imithwalo enzima kakhulu, ehlala idlula iitoni ezili-100, kuxhomekeke kuyilo. Oku kuyenza ibe sisisombululo esithandwayo kumashishini afuna amashishini afana nokwenziwa kwentsimbi, ukwakha iinqanawa, ukuvelisa, kunye nemigca emikhulu yokuhlanganisa. Ngesakhiwo senkxaso esomeleleyo, iikhreyini ezibalekayo eziphezulu zihambisa uzinzo kunye nokomelela okubalaseleyo kokuphakanyiswa okukhulu.
Kwelinye icala, i-crane ye-underhung bridge yenzelwe usetyenziso olulula. Amandla okuphakamisa okuqhelekileyo aphakathi kwe-1 kunye ne-20 yeetoni, ezenza ziphelele kwimigca yendibano, iindibano zocweyo ezincinci zokuvelisa, imisebenzi yokulungisa, kunye nezibonelelo apho ukunyuswa okukhulu kungafunekiyo. Nangona bengenazo umthamo omkhulu womthwalo weekhreyini ezibalekayo eziphezulu, iikhreyini eziphantsi kwe-underhung zibonelela ngesantya, ukusebenza kakuhle, kunye nokuguquguquka kwimithwalo elula.
♦Ukusetyenziswa kwendawo
I-Crane yeBhulorho yokuSebenza ePhezulu: Ngenxa yokuba isebenza kwiintsimbi ezingaphezulu kweeplanga, ifuna izakhiwo zenkxaso ezomeleleyo kunye nokukhutshwa okuthe nkqo okwaneleyo. Oku kunokonyusa iindleko zofakelo kwizibonelelo ezinobude obulinganiselweyo besilingi. Nangona kunjalo, i-advanteji iphezulu yokuphakama kwe-hook, evumela abaqhubi ukuba baphakamise imithwalo kufuphi nophahla kwaye basebenzise ngokupheleleyo indawo ethe nkqo.
I-Underhung Bridge Crane: Ezi cranes zikhanya kwindawo apho indawo ethe nkqo ilinganiselwe. Ekubeni i-crane ijinga kwisakhiwo, inokufakwa ngaphandle kwenkxaso enkulu yendlela yeenqwelo-moya. Zihlala zisetyenziswa kwiindawo zokugcina iimpahla, iindibano zocweyo, kunye nemigca yemveliso enokukhutshwa okuqinileyo. Ukongeza, iinkqubo eziphantsi kwe-underhung zikhulula indawo yomgangatho oxabisekileyo kuba zixhomekeke kwinkxaso ephezulu.

Ukukhetha EOT Ekunene Crane
Xa uthatha isigqibo phakathi kwekhreyini yebhulorho ebalekayo ephezulu kunye nebhulorho ejingayo, kubalulekile ukuqwalasela iimfuno zakho zokusebenza:
Ukuba indawo yakho iphethe imisebenzi enzima yokuphakamisa izinto ezifana nokuveliswa kwentsimbi, ukwakhiwa kweenqanawa, okanye ukuveliswa kwezinto ezinkulu, inkqubo yokusebenza ephezulu iyona ndlela isebenzayo kwaye inokwethenjelwa. Uyilo lwayo olomeleleyo, ukuphakama kwehuku ephezulu, kunye nezakhono ezibanzi ze-span ziyenza ilungele imisebenzi enzima.
Ukuba indawo yakho ijongana nokukhanya ukuya kwimithwalo ephakathi kwaye isebenza kwindawo enemiqobo, inkqubo ephantsi kwe-underhung ingaba sisisombululo esingcono. Ngofakelo olulula, iindleko eziphantsi, kunye nokusebenza kakuhle kwendawo, iikhreyini ezixhonywe ngaphantsi zibonelela ngenye indlela esebenzayo nengabizi kakhulu.
