Rubber tyred gantry crane (RTG crane) ndi chida chosunthika komanso chothandiza kwambiri chomwe chimagwiritsidwa ntchito kwambiri pamadoko, potengera zotengera, mayadi a njanji, ndi malo akulu opangira zinthu. Amapangidwa makamaka kuti azigwira ntchito zotengera chidebe, zomwe zimapereka kusinthasintha, kuyenda, komanso kudalirika pakusunga ndi kusamutsa zotengera. Mosiyana ndi magalasi okhala ndi njanji, chiwombankhanga cha matayala opangidwa ndi mphira amayendera matayala olimba, omwe amawalola kuti aziyenda momasuka pamalo osiyanasiyana monga konkire, phula, ngakhale malo ophatikizika popanda kukhazikika panjira zokhazikika. Kusuntha uku kumapangitsa kuti crane ya RTG ikhale yankho labwino kwa malo omwe amafunikira kusuntha kwa chidebe chosinthika kumadera ambiri.
Mapangidwe a gantry crane yopangidwa ndi matayala nthawi zambiri amakhala chitsulo chooneka ngati U chokhala ndi trolley ndi njira yokwezera yomwe ikuyenda motsatira mtengo wa gantry. Itha kukweza zotengera zazikuluzikulu - 20ft, 40ft, kapena 45ft - pogwiritsa ntchito zida zapadera, ndikuziyika bwino mpaka mizere 6 kapena 7 m'mwamba. Crane ili ndi makina oyendetsa apamwamba, omwe nthawi zambiri amathandizidwa ndi ma jenereta a dizilo kapena mphamvu yamagetsi kudzera munjira zosakanizidwa. Masiku ano RTGcranesnthawi zambiri amakhala ndi ma frequency converters, ukadaulo wobwezeretsa mphamvu, ndi njira zowongolera mwanzeru kuti zitsimikizire kuti zikuyenda bwino, kupulumutsa mphamvu, komanso kuchepetsedwa kwa mpweya wa kaboni, kugwirizanitsa ndi kufunikira kwa chitukuko cha doko lobiriwira.
Ubwino waukulu wama crane a gantry opangidwa ndi mphira wagona pakuwongolera kwawo kwapamwamba komanso mawonekedwe a automation. Ndi ukadaulo wotsutsa-sway, makina oyika bwino, komanso magwiridwe antchito akutali, RTGcranesbwino kwambiri chitetezo ndi kusamalira bwino. Mitundu yodzipangira yokha imatha kupanga masanjidwe osayendetsedwa ndi anthu komanso kukonza njira, kuchepetsa kuchulukira kwa ogwira ntchito komanso kuwopsa kwa magwiridwe antchito.
Pankhani ya ntchito, RTGcranesNdiofunikira kwambiri m'malo osungiramo zinthu ndi mayadi apakati, momwe amawongolera kusamutsa kopingasa ndikusunga moyima, kuwonetsetsa kuti zombo, magalimoto, ndi masitima apamtunda zikuyenda mwachangu. Kusinthasintha kwawo, mphamvu zonyamula katundu, komanso kugwira ntchito mwanzeru kumapangitsa makina opangira mphira kukhala otsika mtengo komanso okonzekera mtsogolo pamakampani amakono opanga zinthu.
♦Kuyendetsa Bwino Kwambiri: Chingwe cha rabara chopangidwa ndi matayala chimakhala ndi mawilo olimba a labala ndi ziwongolero zapamwamba, zomwe zimalola kuti iziyenda mosiyanasiyana mbali zingapo. Itha kugwira ntchito mosavuta m'mayadi olimba a chidebe, madoko, ndi malo osungira, kupangitsa kuti ikhale yosunthika kwambiri pakusunga ndi kutumiza zotengera.
♦Kulemera Kwambiri: Crane ya gantry ya matayala ya rabara yapangidwa kuti izigwira ntchito zolemetsa, yokhala ndi mitundu yambiri yotha kunyamula zotengera zolemera matani 50. Izi zimapangitsa kukhala koyenera kunyamula katundu wambiri pakati pa zombo, magalimoto, ndi malo osungira.
♦ Chitetezo Pansi: Chifukwa cha matayala ake a rabara, crane imagwira ntchito bwino pamalo osiyanasiyana popanda kuwononga. Izi zimatsimikizira kugwira ntchito motetezeka pazipinda zapadera, zomangika, ndi mayadi otengera, ndikuchepetsa ndalama zokonzera nthawi yayitali.
♦ Zida Zachitetezo Chapamwamba: Chitetezo ndi mwayi waukulu wa crane ya tayala ya rabara. Ili ndi ma alarm, masensa, ndi ma hydraulic clamps kuti atsimikizire kukweza kotetezeka komanso kuchepetsa ngozi za ngozi. Njira zotetezerazi zimapangitsa kuti zikhale zodalirika pamadoko otanganidwa komanso ma terminal.
♦Kugwira Ntchito Mwachangu: Chingwe cha rabara cha gantry cha rabara chimatha kugwira ntchito pamanja kapena pawokha, kuchepetsa nthawi yogwirira ntchito ndi zofunikira zantchito. Imagwiranso ntchito ndi zofalitsa zotengera ndi zomata zina zapadera, zomwe zimapangitsa kuti zitheke bwino pakutsitsa ndikutsitsa.
♦ Kugwiritsa Ntchito Ndalama: Pochotsa kufunikira kwa zida zowonjezera zogwirira ntchito, crane ya gantry ya rabara imapereka njira yotsika mtengo yoyendetsera chidebe ndi kusungirako. Kudalirika kwake komanso kusinthika kwake kumapangitsa kuti ikhale chisankho chokondedwa kwamakampani onyamula katundu ndi kutumiza padziko lonse lapansi.
Rubber tyred gantry crane (RTG crane) ndi makina onyamulira osunthika osunthika omwe amagwiritsidwa ntchito kwambiri m'madoko, mayadi otengera, ndi ma terminals pakunyamula katundu moyenera. Mosiyana ndi ma crane okhala ndi njanji, crane ya RTG imadalira matayala olimba a rabara m'malo mwa mayendedwe okhazikika, ndikupangitsa kuti ikhale yosinthasintha, yotsika mtengo, komanso kusamuka kosavuta kumadera osiyanasiyana ogwirira ntchito. Womangidwa ndi chimango cholimba cha gantry chomwe chimakhala ndi chotchingira chachikulu komanso makina onyamulira, crane ya RTG idapangidwa kuti izitha kunyamula zotengera zolemetsa ndi mayunitsi apakati mwatsatanetsatane.
Sitima yapamadzi kapena galimoto ikafika pamalo ofikira, RTG crane imatha kupita komwe kuli katundu. Mawilo ake olemera a rabara amawalola kuti aziyenda bwino pamalo osiyanasiyana, kuphatikiza misewu ya madoko, mayadi a konkire, ngakhale kudutsa njanji. Kuwongolera kwakukulu kumeneku kumatsimikizira kuti crane ya RTG imatha kusintha mwachangu kusintha kwa ntchito, kuchepetsa nthawi yopumira ndikuwongolera magwiridwe antchito.
Ubwino wofunikira pakugwirira ntchito kwa crane ya rabara ya gantry ndi kuthekera kwake kowongolera. Crane imatha kuzungulira, kugwirizanitsa ndi milu ya zotengera, ndikuyenda m'malo olimba mokhazikika. Yokhala ndi makina odalirika owongolera ndi mabuleki, crane ya RTG imawonetsetsa kukweza bwino komanso kuyenda kwa zotengera ngakhale pamalo otanganidwa.
Njira yokwezayi imayendetsedwa ndi magetsi kapena ma hydraulic system, omwe amayendetsa chokweza kuti chikweze, kutsitsa, ndikunyamula katundu wolemetsa. Ndi zinthu monga kukweza kosalala, anti-sway control, ndi malo olondola, crane ya RTG imatsimikizira kusungitsa bwino kwa chidebe ndikuchotsa.
Pomaliza, crane ya gantry ya rabara ndiyofunikira kwambiri pamayendedwe amakono ndi kutumiza. Kuphatikiza kwake kwa kuyenda, kusinthasintha, ndi kukweza bwino kumapangitsa kuti crane ya RTG ikhale chinthu chofunikira kwambiri pamadoko ndi ma terminals, kuwonetsetsa kuti katundu akuyenda mwachangu, motetezeka, komanso motsika mtengo pamayendedwe onse apadziko lonse lapansi.
