Zofunikira pakugwiritsa ntchito ndi kusamalira ma crane a gantry panthawi yogwira ntchito zitha kufotokozedwa mwachidule motere: kulimbitsa maphunziro, kuchepetsa katundu, kuyang'anira kuyang'anira, ndi kulimbitsa mafuta. Bola ngati muika kufunika kokonza ndi kukonza panthawi yogwira ntchito ya crane malinga ndi zofunikira, zimachepetsa kulephera koyambirira, kukulitsa nthawi yogwira ntchito, kukonza magwiridwe antchito, ndikubweretsa phindu lalikulu ku makinawo.
Kreni ya gantry ikachoka ku fakitale, nthawi zambiri imayenda kwa maola pafupifupi 60. Izi zimafotokozedwa ndi fakitale yopanga kutengera ukadaulo wa kagwiritsidwe ntchito koyamba ka kreni. Kuyenda kwa nthawi ndi njira yofunika kwambiri yotsimikizira kuti kreni ikugwira ntchito bwino, kuchepetsa kulephera, ndikuwonjezera nthawi yake yogwirira ntchito.
Makhalidwe a kuthamanga mu nthawi yama crane a gantry:
1. Kuchuluka kwa kusweka kumathamanga. Chifukwa cha zinthu monga kukonza, kusonkhanitsa, ndi kusintha kwa zigawo zatsopano za makina, pamwamba pa kukangana kumakhala kolimba, malo olumikizirana a pamwamba pa kukangana ndi ochepa, ndipo mkhalidwe wa kupanikizika kwa pamwamba siwofanana. Panthawi yogwira ntchito ya makina, zigawo zopingasa ndi zopingasa pamwamba pa zigawo zimalumikizana ndikukandana. Zinyalala zachitsulo zomwe zimagwa zimakhala zokwawa ndipo zimapitiriza kutenga nawo mbali pakukangana, zomwe zimapangitsa kuti pamwamba pa kukangana pazigawozo pakhale kusweka mwachangu. Chifukwa chake, panthawi yogwira ntchito, zimakhala zosavuta kuyambitsa kuwonongeka kwa zigawozo, ndipo kuchuluka kwa kusweka kumakhala kofulumira. Pakadali pano, ngati ntchito yolemetsa ichitika, ikhoza kuwononga zigawozo ndikupangitsa kuti zilephereke msanga.
2. Mafuta odzola osakwanira. Chifukwa cha kutseguka pang'ono kwa zinthu zatsopano zomwe zasonkhanitsidwa komanso kuvutika kuonetsetsa kuti zinthuzo zikugwirizana chifukwa cha kusonkhana ndi zifukwa zina, mafuta odzola sikophweka kupanga filimu yamafuta yofanana pamwamba pa kugwedezeka kuti apewe kuwonongeka. Izi zimachepetsa kugwiritsa ntchito mafuta bwino ndipo zimayambitsa kuwonongeka koyambirira kwa zinthuzo. Pa milandu yoopsa, zimatha kukanda kapena kuluma pamwamba pa kugwedezeka kwa zinthu zolondola, zomwe zimapangitsa kuti pakhale zolakwika.
3. Kumasuka kumachitika. Zigawo zomwe zakonzedwa ndi kusonkhanitsidwa kumene zimakhala ndi kusintha kwa mawonekedwe ndi kukula koyenera. Poyamba kugwiritsidwa ntchito, chifukwa cha zinthu zosiyanasiyana monga kugwedezeka ndi kugwedezeka, komanso zinthu monga kutentha ndi kusintha, kuphatikiza kuwonongeka mwachangu, zimakhala zosavuta kuti zigawo zomwe zidamangidwa poyamba zisamasuke.
4. Kutaya madzi kumachitika. Chifukwa cha kumasuka, kugwedezeka, ndi kutentha kwa zigawo za makina, kutaya madzi kungachitike pamalo otsekera ndi malo olumikizira mapaipi a makina. Zolakwika zina monga kuponyera ndi kukonza zimakhala zovuta kuzizindikira panthawi yosonkhanitsa ndi kukonza, koma chifukwa cha kugwedezeka ndi kukhudzidwa panthawi yogwira ntchito, zolakwikazi zimaonekera, zomwe zimaonekera ngati kutaya mafuta. Chifukwa chake, kutaya madzi kumachitika nthawi yomwe ikuyenda.
5. Pali zolakwika zambiri pakugwira ntchito. Chifukwa cha kusamvetsetsa bwino kapangidwe ndi momwe ma gantry cranes amagwirira ntchito, n'zosavuta kuyambitsa zolakwika komanso ngozi zamakina chifukwa cha zolakwika pakugwira ntchito.
