Ekuphatheni izinto ezibonakalayo, i-gantry crane iyithuluzi elinamandla neliguquguqukayo, eliguqula ukuphathwa kwemithwalo emagcekeni angaphandle, emachwebeni nasezindaweni zokwakha.
I. Iyini i-Gantry Crane?
I-crane ye-gantry inohlaka lwensimbi olumise okwe-gantry (njengomnyango) olunomshayo wokuphakamisa (i-girder eyinhloko) osekelwe yimilenze emibili. Le milenze ihamba ngezinsimbi zomhlabathi, okwenza kube lula ukuhamba ngokuvundlile. Eminye imiklamo ineziphetho ze-girder eyinhloko ezigoqwe nge-cantilevered ukuze kube nobubanzi bokusebenza.
II. Izinhlobo zama-Gantry Cranes
1. Ngesakhiwo se-Gantry
I-Full-gantry Crane: Izinzile, ayinazo izimbobo eziyinhloko ze-girder overhangs, ifanele imisebenzi ejwayelekile ezindaweni ezivalekile.
I-Semi-gantry Crane: Imilenze inokwehluka kokuphakama, ivumelana nomhlabathi ongalingani noma izakhiwo ezikhona ezindaweni ezikhethekile zezimboni.
I-Full-Gantry Crane
I-Semi-Gantry Crane
2. Ngu-Cantilever Design
I-Gantry Crane ene-cantilever ekabili: I-girder eyinhloko idlula ngale kwemilenze yomibili, ithuthukisa ukusetshenziswa kwendawo, ilungele amachweba noma amayadi amakhulu emithwalo.
I-Gantry Crane eyodwa ene-cantilever: Isandiso esisodwa, esisebenziseka ezindaweni ezivinjelwe isikhala njengezitshalo ezincane.
3. Ngesakhiwo Esiyinhloko Sebhande
I-Gantry Crane enebhande elilodwa: Ilula, ishibhile, inohlaka olumise okwebhokisi. Ifanele imithwalo emincane kuya kwephakathi (q ≤ 50t, s ≤ 35m), isib., emafektri amancane.
I-Gantry Crane enezinsika ezimbili: Iqinile, inkulu, izinzile. Izinhlobo zifaka:
a. Ibhokisi - ibhande I-Crane: Ukuphepha okuphezulu, ukuqina okukhulu, kwemisebenzi enzima (isb., izindawo zokupaka imikhumbi), kodwa kuyabiza futhi kuyasinda.
b. I-Truss - girder I-Crane: Intengo ephansi, elula, ukumelana nomoya okuhle, kodwa idinga ukushiselwa njalo - ukuhlolwa kwamaphuzu, uma imithwalo emincane inzima.
c. I-Honeycomb - girder Crane: Ihlanganisa izici ze-truss kanye nebhokisi, ezithembekile, ezindaweni ezithwala umthwalo ovamile noma osindayo (isb., amayadi emishayo yebhuloho).

4. Ngesicelo
I-General Gantry Crane: Ibanzi - ukusetshenziswa, iphatha izimpahla ezahlukahlukene, umthamo wokuphakamisa ungaphansi kwamathani ayi-100, ububanzi buyi-4 - 39m.
I-Hydropower Station Gantry Crane: Amasango okuphakamisa, ukufakwa, umthamo wamathani angu-80 - 500, ububanzi obuncane (8 - 16m).
I-Gantry Crane yokwakha imikhumbi: Ihlanganisa ama-shell, anomthamo wamathani ayi-100 - 1500, ububanzi obukhulu (kufika ku-185m).
I-Container Gantry Crane: Izitaki/ukulayisha izitsha, isitimela noma irabha - zikhathele, zisezingeni eliphezulu labasebenzi, zifinyelela kumamitha angu-60.
III. Isakhiwo kanye nesimiso sokusebenza
1. Izingxenye Eziyinhloko
Uhlaka lwe-Gantry: Lwenziwe ngensimbi, luxhumanisa amabhande amakhulu ukuze kuqiniswe.
Ibhande Eliyinhloko: Ugongolo lwensimbi, olulingana nomthwalo kanye nobuningi.
Indlela Yokuphakamisa: Ihlanganisa injini, i-reducer, njll., elawula ukuphakamisa.
Indlela Yokuhamba: Inamasondo, injini, ihambisa i-crane.
Indlela Yokuhamba Ngenqola: Ihambisa izimpahla ngenjini, izintambo, njll.
Uhlelo Lokulawula Ugesi: Imisebenzi yokuqapha nokulawula.
2. Isimiso Sokusebenza
Umqhubi uhambisa i-crane endaweni yayo.
I-trolley ibamba futhi iphakamisa izimpahla.
Indlela yokuhamba inyakazisa ibhande elilayishiwe.
I-trolley ibeka izimpahla endaweni oya kuyo.
IV. Izinzuzo kanye nokungalungi
1. Izinzuzo
Ukusetshenziswa Kwendawo Ephakeme: Isitimela - sisebenza kahle, akukho ukuphazamiseka kwethayi/ijeneretha, sisebenzisa isikhala kahle.
Indawo Enkulu Yokusebenza: Ama-Cantilever kanye nokuhamba kwesitimela kuhlanganisa izindawo ezibanzi.
Ukuzivumelanisa Nezimo Okuqinile: Kungenziwa ngezifiso kumasayithi/izidingo (isb., i-semi-gantry yomhlabathi ongalingani).
Ukusebenza okungabizi kakhulu: Kuqhutshwa ngogesi, ukulungiswa okuncane, ukonga amandla kungenzeka.
Ukuzenzakalela Okuphezulu: Ukuphathwa okunembile ngezinhlelo zokulawula nokubeka.
2. Ukungalungi
Isimo Sezulu - Kungathinteka: Ukusetshenziswa ngaphandle kuyingozi yokugqwala (okubangelwa yimvula) kanye nokushelela/ukugumbuqela (okubangelwa umoya), okudinga izinyathelo zokuzivikela.
Indawo - Okuxhomeke kuyo: Ithembela ezitimeleni; ukubeka/ukulungisa izitimeleni kubiza isikhathi nemali.
Ukutshalwa Kwezimali Okuphezulu Kokuqala: Ukuklama, ukukhiqiza, kanye nokufaka kuyabiza, ikakhulukazi kuma-crane amakhulu noma akhethekile.
V. Izinkambu Zokufaka Isicelo
Ama-crane e-gantry asebenza:
Ubunjiniyela be-Hydraulic: Ukwakha/ukunakekela amadamu, izingidi zemikhumbi, amasango okuphakamisa.
Ukwakha: Phatha/faka izinto zokwakha ezindaweni eziphakeme, amabhuloho.
Ukukhiqiza: Hlanganisa izinto zokusebenza ezinkulu emishinini, ezimbonini zezimoto.
Amakhemikhali kaphethroli, Ukumba, Ukwakha imikhumbi: Thutha imishini esindayo, izinto zokusetshenziswa.
Amachweba: Ukulayisha/ukukhipha izitsha, imithwalo emikhulu.
TI-crane ye-gantry, enezinhlobo ezahlukene, isakhiwo esizinzile, kanye nokusetshenziswa okubanzi, ibalulekile ekuphathweni kwezinto zanamuhla. Naphezu kwemingcele, ukusungula izinto ezintsha kuthuthukisa ukusebenza kwayo, kusiza ukusebenza kahle kwemboni.
Isikhathi sokuthunyelwe: Juni-26-2025
