Ama-Gantry cranes ayimishini esindayo evame ukusetshenziswa emachwebeni, ezindaweni zemikhumbi, nasezindaweni zasezimbonini ukuphakamisa nokuhambisa imithwalo esindayo. Ngenxa yokuchayeka njalo esimweni sezulu esibi, amanzi olwandle, nezinye izakhi ezigqwalile, ama-gantry cranes asengozini enkulu yokulimala ukugqwala. Ngakho-ke, kubalulekile ukuthatha izinyathelo ezifanele zokunqanda ukugqwala ukuze kuvikelwe i-gantry crane ekuhlulekeni ngaphambi kwesikhathi, kwandiswe isikhathi sayo sokuphila, nokuqinisekisa ukuphepha nokukhiqiza okuphezulu. Ezinye zezinyathelo zokulwa nokugqwala kweama-gantry craneszimi kanje.
1. Ukugqoka: Esinye sezinyathelo eziphumelela kakhulu zokunqanda ukugqwala kwama-gantry cranes ukumboza. Ukusebenzisa izinto ezivimbela ukubola njenge-epoxy, i-polyurethane, noma i-zinc kungavimbela amanzi nomoya-mpilo ukuthi ungafinyeleli endaweni yensimbi futhi wenze nokugqwala. Ngaphezu kwalokho, ukunamathela kungasebenza njengesithiyo ngokumelene nokuhuzuka, ukuhlaselwa kwamakhemikhali, nemisebe ye-ultraviolet, ngaleyo ndlela kuthuthukise ukuqina nobuhle be-crane.
2. Ukunakekela: Ukuhlola njalo nokugcinwa kwe-gantry crane kungavimbela ukugqwala ngokuthola nokulungisa noma yimuphi umonakalo noma ukukhubazeka ngokushesha. Lokhu kuhlanganisa ukuhlanza ingaphezulu lika-crane, ukugcoba amalunga, ukushintsha izingxenye ezigugile, kanye nokuqinisekisa ukugeleza kahle kwamanzi emvula nolunye uketshezi.
3. Ukufakwa uthayela: Ukufakwa uthayela kuyinqubo yokumboza insimbi ngongqimba lwezinki ukuze ivikeleke ekugqwaleni. Lokhu kungenziwa ngokusebenzisa i-hot-dip galvanizing noma i-electroplating, kuye ngobukhulu be-crane nendawo. Insimbi eyenziwe ngegalazi imelana kakhulu nokugqwala futhi iphila isikhathi eside kunensimbi engamboziwe.
4. Ukuthuthwa kwendle: Ukugeleza kwamanzi emvula ngendlela efanele kubalulekile ukuze kugwenywe ukugqwala kwe-gantry crane, ikakhulukazi ezindaweni ezijwayele ukuba nemvula enkulu noma izikhukhula. Ukufaka ama-gutters, ama-downspout, kanye nemigudu yokukhipha amanzi kungaqondisa amanzi kude ne-crane futhi kuvimbele ukunqwabelana kwamanzi amile.
Kafushane, izinyathelo zokunqanda ukugqwala kwama-gantry cranes zibalulekile ukuze kuqinisekiswe ukuphila kwabo isikhathi eside, ukuphepha, kanye nokukhiqiza. Ukusebenzisa inhlanganisela yokumboza, ukunakekela, ukwenza uthayela, kanye nokukhipha amanzi kungavikela ingaphezulu lensimbi ye-crane ekugqwaleni futhi kuthuthukise ukusebenza kwayo nempilo yayo.
