Ama-cranes e-gantry kanye nemishini yebhuloho imishini emibili ephakeme yokuphakamisa, esetshenziswa kabanzi ezimbonini, emachwebeni, ezindaweni zokugcina izimpahla kanye nezinye izinkambu. Banezimpawu zabo ezakhiweni, ukusebenza kanye nezimo zokusetshenziswa. Okulandelayo ukuqhathanisa okuningiliziwe:
1. Gantry craneIzici Zokwakheka:
Indlela yokusekela: Ixhaswe yimilenze (gantry) nhlangothi zombili emhlabathini ithrekhi noma isisekelo esilungisiwe sokwakha isakhiwo "somnyango".
Ugongolo: Ugongolo oluphambili luphensele imilenze nhlangothi zombili futhi lungahlome ngogongolo olulodwa noma ugongolo oluphindwe kabili.
Ukuhamba: Ngokuvamile kuhamba eduze kwethrekhi yomhlabathi, futhi amanye amamodeli (anjengeTire-Type Gantry Cranes) awadingi amathrekhi.
Ukuhlukaniswa:
I-Gantry-Type Gantry Crane: isebenza kumathrekhi ahleliwe, inokuqina okuphezulu, futhi ilungele izindawo zokusebenza ezimisiwe.
I-Gantry-Type Gantry Crane (RTG): I-Tracless, iguquguqukayo futhi iselula, evame ukutholakala emayadini athile.
I-ShipBuilding Gantry Crane: I-Super Grough Tonnage, esetshenziselwa imikhumbi.
Izinzuzo:
Isikhala esikhulu: Ilungele amasayithi avulekile anomoya afana namachweba, amayadi, kanye neziza zokwakha.
Umthamo onamandla wokuthwala: Ungenziwa nge-Living Photha yamakhulu ezinkulungwaneni zamathani.
Ukuqina okuqinile: Akukhawulelwe ukuphakama kwesitshalo, kungasebenza ezindaweni ezinokhahlo.
Okubi:
Isinyathelo esikhulu sezinyawo: Kudingeka ukubeka amathrekhi noma ukubeka indawo ehambayo.
Izindleko eziphakeme: ama-cranes amakhulu e-gantry ayinkimbinkimbi ukukhiqiza futhi afake.
Izicelo ezejwayelekile:
Isitsha sokulayisha nokulayisha, imikhumbi, ukufakwa okukhulu kwensimbi yensimbi, imishini yamandla omoya iyakhuphula.
2. Ngaphezulu kwe-craneIzici Zokwakheka:
Indlela yokusekela: Womabili ama-Exs of the Beam Main asekelwa kuthrekhi (ugongolo olujikelezayo) ngaphezulu kwesitshalo ngamasondo, ngaphandle kwemilenze yomhlaba.
Isikhala esisebenzayo: Hambisa ngokuvundlile kwithrekhi esekelwa udonga lwezitshalo noma ikholomu, futhi i-trolley igijimisana ngokuhamba phambili eceleni komshini omkhulu.
Ukulungiswa: Kuvame ukulungiswa ngaphakathi kwesakhiwo.
Ukuhlukaniswa:
I-Single-Beam Bridge Crane: Isakhiwo esikhanyayo, esilungele ukuphakamisa okukhanyayo (≤20 Tons).
I-Double-Beam Bridge Crane: Ukuqina okuhle, okulungele i-tonnage enkulu (kufinyelela kumakhulu amathani).
I-Crane yeBridge Emisiwe: Ugongolo oluphambili lumisiwe ngaphansi kwesakhiwo sophahla ukusindisa isikhala.
Izinzuzo:
Gcina indawo yomhlaba: ayihlali ithrekhi yomhlabathi, ilungele imisebenzi ebanzi efektri.
Ukusebenza okubushelelezi: Ithrekhi isendaweni ephakeme futhi ayiphazamiseki kancane phansi.
Ukusebenza okuguquguqukayo: kungasebenza ngokulawula okukude noma i-cab.
Okubi:
Kuya ngesakhiwo sefektri: isakhiwo sidinga ukuba nomthamo owenele wokuthwala umthwalo.
I-SPAN Enqunyelwe: Inqunyelwe ububanzi befektri, ngokuvamile hhayi ngaphezu kwamamitha angama-30- 40.
Izicelo ezejwayelekile:
Ukusingathwa kwezinto ezibonakalayo endaweni yokusebenzela, ukugqugquzela imigqa yokukhiqiza, ukulayisha kanye nokulayisha kwezindawo zokugcina impahla, kanye nomhlangano wemishini.
Ama-gantry cranes kanye nezincomo zokukhethwa kwebhulohoKhetha i-gantry crane:
Kudinga imisebenzi yangaphandle, izikhala ezinkulu, kanye nezinsimbi ezinkulu zokuphakamisa (njengamachweba, amandla omoya, kanye nokwakha umkhumbi).
Khetha i-crane yebhuloho:
Ukuphakamisa endaweni ehleliwe efektri, isikhala esinqunyelwe, kanye nemisebenzi ejwayelekile (efana nemisho yokucobelela efekthri).
Ngokusho kokuhlola okuphelele kwezidingo ezithile (Isisindo esiphakamisayo, i-span, imvelo, isabelomali), izimo ezikhethekile nazo zingabheka umklamo we-hybrid walezi ezimbili (ezifana ne-semi-gantry crane).
