Pakusamalira zinthu, gantry crane ndi chida champhamvu komanso chosinthasintha, chomwe chimasintha kwambiri momwe munthu amagwiritsira ntchito katundu m'mabwalo akunja, m'madoko, komanso m'malo omanga.
I. Kodi Gantry Crane ndi chiyani?
Kreni ya gantry ili ndi chimango chachitsulo chooneka ngati gantry (monga chitseko) chokhala ndi mtanda wonyamulira (girder yayikulu) wochirikizidwa ndi miyendo iwiri. Miyendo iyi imayenda m'njira zopingasa, zomwe zimathandiza kuyenda mopingasa. Mapangidwe ena ali ndi malekezero a girder yayikulu kuti agwire ntchito mokulirapo.
II. Mitundu ya Ma Gantry Cranes
1. Ndi Kapangidwe ka Gantry
Crane Yodzaza ndi Gantry: Yokhazikika, yopanda magirder overhangs, yoyenera ntchito zanthawi zonse m'malo otsekeka.
Semi-gantry Crane: Miyendo imakhala ndi kutalika kosiyana, imasintha malinga ndi nthaka yosagwirizana kapena nyumba zomwe zilipo kale m'malo apadera a mafakitale.

Kireni ya Semi-Gantry
2. Ndi Cantilever Design
Gantry Crane yokhala ndi cantilever ziwiri: Chingwe chachikulu chimadutsa miyendo yonse iwiri, zomwe zimapangitsa kuti malowo agwiritsidwe ntchito bwino, ndipo ndi abwino kwambiri pamadoko kapena malo akuluakulu onyamula katundu.
Gantry Crane imodzi yokha: Yowonjezera mbali imodzi, yothandiza m'malo ochepa monga zomera zopapatiza.
3. Ndi Kapangidwe ka Main Girder
Gantry Crane yokhala ndi girder imodzi: Yosavuta, yotsika mtengo, yokhala ndi chimango chooneka ngati bokosi. Yoyenera katundu wochepa mpaka wapakati (q ≤ 50t, s ≤ 35m), mwachitsanzo, m'mafakitale ang'onoang'ono.
Gantry Crane yokhala ndi mipiringidzo iwiri: Yamphamvu, yayikulu, yokhazikika. Mitundu yosiyanasiyana ndi iyi:
a. Bokosi - girder Kireni: Yotetezeka kwambiri, yayikulu - yolimba, ya ntchito zolemera (monga malo opangira zombo), koma yokwera mtengo komanso yolemera.
b. Truss - girder Crane: Yotsika mtengo, yopepuka, yolimba ndi mphepo, koma imafunika kuwotcherera pafupipafupi - kuyang'ana malo, ngati katunduyo ndi wochepa.
c. Chigoba cha uchi - girder Crane: Chimaphatikiza zinthu za truss ndi bokosi, zodalirika, kuti zigwiritsidwe ntchito pafupipafupi kapena zolemera (monga mayadi a milatho ya mlatho).
Kireni Yokhala ndi Grider Imodzi
Kireni ya Grider Yawiri
4. Pogwiritsa ntchito
Kireni ya General Gantry: Yogwiritsidwa ntchito kwambiri, imagwirira ntchito katundu wosiyanasiyana, mphamvu yonyamula katundu yosakwana matani 100, kutalika kwake ndi mamita 4 - 39.
Kireni ya Gantry ya Siteshoni ya Mphamvu ya Madzi: Zipata zokwezera, kuyika, mphamvu ya matani 80 - 500, kutalika kochepa (8 - 16m).
Crane Yopangira Zombo: Imasonkhanitsa ma shells, okhala ndi mphamvu zokwana matani 100 - 1500, kutalika kwakukulu (mpaka 185m).
Kireni ya Gantry ya Chidebe: Milu/kunyamula zidebe, njanji kapena rabala - yotopa, ya antchito apamwamba, imafikira mamita 60.
III. Kapangidwe ndi Mfundo Yogwirira Ntchito
1. Zigawo Zazikulu
Chimango cha Gantry: Chopangidwa ndi chitsulo, chimalumikiza magirders akuluakulu kuti chikhale chokhazikika.
Chitsulo chachikulu: Mtanda wachitsulo, kukula kwake malinga ndi katundu ndi kuchuluka kwake.
Njira Yokwezera: Ikuphatikizapo injini, chochepetsera, ndi zina zotero, zomwe zimawongolera kukweza.
Njira Yoyendera: Ili ndi mawilo, injini, imayendetsa crane.
Njira Yoyendera Magalimoto: Imayendetsa katundu kudzera mu injini, zingwe, ndi zina zotero.
Dongosolo Lowongolera Magetsi: Ntchito zowunikira ndi kuwongolera.
2. Mfundo Yogwirira Ntchito
Woyendetsa amasuntha crane pamalo ake.
Trolley imatenga ndikunyamula katundu.
Njira yoyendera imasuntha girder yodzaza.
Trolley imayika katundu pamalo omwe ikupita.
IV. Ubwino ndi Kuipa
1. Ubwino
Kugwiritsa Ntchito Malo Ofunika Kwambiri: Sitima - imayenda bwino, palibe kusokoneza matayala/jenereta, imagwiritsa ntchito malo bwino.
Malo Ogwirira Ntchito Akuluakulu: Ma cantilever ndi sitima zoyendera zimaphimba madera ambiri.
Kusinthasintha Kwamphamvu: Kusinthidwa malinga ndi malo/zosowa (monga, malo otsetsereka pang'ono kuti nthaka isafanane).
Ntchito Yotsika Mtengo: Yoyendetsedwa ndi magetsi, yosakonzedwa bwino, komanso yosunga mphamvu.
Makina Odziyendetsa Mwachangu: Kugwira ntchito molondola kudzera mu makina owongolera ndi oyika zinthu pamalo oyenera.
2. Zoyipa
Nyengo - Yosakhazikika: Kugwiritsa ntchito panja kungachititse dzimbiri (chifukwa cha mvula) ndi kutsetsereka/kugubuduzika (chifukwa cha mphepo), zomwe zimafunika njira zodzitetezera.
Malo - Odalira: Amadalira njanji; kuyala/kukonza njanji kumawononga nthawi ndi ndalama.
Ndalama Zoyambira Kwambiri: Kupanga, kupanga, ndi kukhazikitsa ndi okwera mtengo, makamaka pa ma crane akuluakulu kapena apadera.
V. Minda Yofunsira
Ma crane a Gantry amagwira ntchito:
Uinjiniya wa Hydraulic: Kumanga/kusamalira madamu, maloko a sitima, zipata zokwezera.
Kapangidwe: Gwirani/ikani zipangizo zomangira m'malo okwera, milatho.
Kupanga: Kusonkhanitsa zida zazikulu zogwirira ntchito m'makina, mafakitale a magalimoto.
Mafuta, Migodi, Kumanga Zombo: Kusuntha zida zolemera, zipangizo zopangira.
Madoko: Kunyamula/kutsitsa ziwiya, katundu wolemera.
TKreni ya gantry, yokhala ndi mitundu yosiyanasiyana, kapangidwe kokhazikika, komanso kugwiritsidwa ntchito kwambiri, ndi yofunika kwambiri pakugwiritsa ntchito zipangizo zamakono. Ngakhale kuti pali malire, luso lamakono limawonjezera magwiridwe ake, zomwe zimathandiza kuti makampani azigwira bwino ntchito.
