Ukuqonda ukuhlukaniswa kwama-gantry cranes kulungele ukukhetha nokuthenga ama-cranes. Izinhlobo ezahlukene zama-cranes nazo zinokuhlukaniswa okuhlukile. Ngezansi, le ndatshana izokwethula izici zezinhlobo ezahlukahlukene zama-cranes gantry ngokuningiliziwe kumakhasimende azosebenzisa njengesethenjwa lapho ekhetha ukuthenga i-crane.
Ngokwendlela yokwakheka kohlaka lwe-crane
Ngokwesimo sesakhiwo sohlaka lomnyango, singahlukaniswa saba yi-gantry crane kanye ne-cantilever gantry crane.
Ama-gantry craneszihlukaniswe:
1. I-Gantry Crane ephelele: Ugongolo oluphambili alunayo i-overhang, kanye nokuhamba kwe-trolley ngaphakathi kwe-span enkulu.
2. Semi-Gantry Crane: Ngokusho kwezidingo zokwakha umphakathi, ukuphakama kwabakhishwe kuyahlukahluka.
Ama-cantilever gantry cranes ahlukaniswe:
1. Double Cantilever Gantry Crane: Enye yamafomu ajwayelekile kakhulu, ukucindezelwa kwawo kwesakhiwo kanye nokusetshenziswa okusebenzayo kwendawo yendawo kunengqondo.
2. I-Canry Crane engashadile ye-cantilever gantry: Ngenxa yemikhawulo yesayithi, lesi sakhiwo sivame ukukhethwa.
Ukuhlukaniswa ngokwesimo nohlobo lomshini omkhulu we-gantry crane:
1. Qedela ukuhlukaniswa kwemishini eyodwa ye-girter gansres eyodwa
I-Wind-Gander Crane elula, kulula ukuyenza futhi ifake, futhi inenqwaba encane. Iningi lemishayo yalo eyinhloko lizithandela izakhiwo zozimele zejele. Uma kuqhathaniswa ne-gantry crane ephindwe kabili, ukuqina okuphelele kubuthakathaka. Ngakho-ke, lapho amathani wokuphakamisa we-Q≤50, i-span s≤35m.
I-One Garder Gantry CraneImilenze eminyango iyatholakala ngohlobo lwe-L no-C-TYPE. Imodeli ye-L-Shaped kulula ukuyifaka, inokumelana kahle kwamandla, futhi inenqwaba encane, kepha isikhala sokuphakamisa izimpahla ngemilenze sincane. Imilenze eyenziwe ngama-C igayiwe noma igobe ukuhlinzeka indawo enkulu evundlile yemithwalo yempahla yokudlula kahle ngemilenze.
2. Qedela ukuhlukaniswa kwama-ndrry ama-ndrry ama-double girter
I-Double-girder gantry cranesYiba nomthamo oqinile, izikhala ezinkulu, ukuqina okuhle, nezinhlobonhlobo eziningi, kepha isisindo sazo sikhulu kune-gantry cranes eyodwa yokuphakamisa, futhi izindleko ziphakeme.
Ngokusho kwezakhiwo ezihlukile ze-Beam Main, zingahlukaniswa ngezindlela ezimbili: Ibhokisi logongolo kanye neTruss. Njengamanje, izinhlaka zohlobo lwebhokisi zivame ukusetshenziswa.
Ukuhlukaniswa ngokuya ngesakhiwo esikhulu se-Gantry Crane:
1. UTruss girder gantry crane
Isakhiwo se-welded sensimbi engela noma i-weam sinezinzuzo zezindleko eziphansi, isisindo esikhanyayo kanye nokumelana nomoya okuhle.
Kodwa-ke, ngenxa yenani elikhulu lamaphoyinti we-welding, i-truss ngokwayo inezinkinga. I-Truss Beam nayo inamaphutha afana nokuphambuka okukhulu, ukuqina okuphansi, ukuthembeka okuphansi, kanye nesidingo sokuthola njalo kwamaphoyinti we-welding. Ilungele amasayithi anezidingo eziphansi zokuphepha kanye nesisindo esincane sokuphakamisa.
2. I-Box Garder Gantry Crane
Amapuleti ensimbi afakwe ekwakhiweni okwenziwe ngebhokisi, elinezimpawu zokuphepha okuphezulu nokuqina okuphezulu. Ngokuvamile esetshenziselwa i-tonnage enkulu kanye nemigwaqo emikhulu ye-tonnage gantry. Umbhede omkhulu wamukele ukwakheka kwebhokisi lebhokisi. Ama-Box Beams abuye abe nobubi bezindleko eziphezulu, isisindo esifile, kanye nokumelana nomoya ompofu.
3. I-Honeycomb benga gantry crane
Ngokuvamile ibizwa nge- "Isoscelos Triangle deneycomb beam", ubuso bokuphela bogongolo oluyinhloko luyinxantathu, futhi kunezimbobo zezinyosi ezinhlangothini zombili zesisu esisesiswini, phezulu nangaphansi. Imishayo yamaselula ibamba izici ze-truss beams kanye nemishayo yebhokisi, futhi ibe nokuqina okukhulu, ukunqotshwa okuncane kanye nokwethenjwa okuphezulu kunokwethenjwa kweTruss.
Kodwa-ke, ngenxa ye-welding yamapuleti ensimbi, okusindayo nezindleko kuphakeme kancane kunaleyo ye-Truss Beams. Ilungele ukusetshenziswa okusetshenziswa njalo noma izingosi ezisindayo noma amasayithi we-beam. Ngoba lolu hlobo lwe-beam ngumkhiqizo wokuphathelene, kukhona abakhiqizi abambalwa.
