Kunqatshelwe ngokuphelele ukusebenzisaama-gantry cranesngale kwemininingwane. Abashayeli akufanele bawasebenzise ngaphansi kwezimo ezilandelayo:
1. Ukulayishwa ngokweqile noma izinto ezinesisindo esingacacile azivunyelwe ukuphakanyiswa.
2. Isignali ayicacile futhi ukukhanya kumnyama, okwenza kube nzima ukubona ngokucacile.
3. Ukuthi impahla yokuphepha ye-crane iyahluleka, okokusebenza kwemishini kwenza umsindo ongajwayelekile, noma i-crane yehluleka ukuphakama ngenxa yokungasebenzi kahle.
4. Intambo yocingo ayizange ihlolwe, ihlanganiswe, noma ilengiswe ngokuphephile noma ingalingani ngaleyo nyanga futhi ingase ishelele futhi yehluleke ukulengiswa.
5. Ungaphakamisi izinto ezisindayo ngaphandle kokwengeza i-padding phakathi kwamachopho namakhona entambo yensimbi.
6. Ungayiphakamisi into ezophakanyiswa uma kukhona abantu noma izinto ezintantayo phezu kwayo (ngaphandle kwama-hoists akhethekile athwala abantu).
7. Lengisa izinto ezisindayo ngokuqondile ukuze zicutshungulwe, futhi uzilengise ngokudayagonali esikhundleni sokuzilengisa.
8. Ungaphakamisi esimweni sezulu esibi (umoya onamandla/imvula enkulu/inkungu) noma ezinye izimo eziyingozi.
9. Izinto ezigqitshwe ngaphansi komhlaba akufanele zisuswe uma isimo sazo singaziwa.
10. Indawo yokusebenza imnyama futhi akunakwenzeka ukubona ngokucacile indawo nezinto eziphakanyiswayo, futhi isignali yomyalo ayiphakanyiswa.
Abashayeli kufanele bahambisane nezidingo ezilandelayo ngesikhathi sokusebenza:
1. Ungasebenzisi iswishi yomkhawulo wesikhundla ngokwedlulele ngezinjongo zokupaka emsebenzini
2. Ungawalungisi amabhuleki omshini wokuphakamisa nowokumisa ngaphansi komthwalo.
3. Lapho uphakamisa, akekho ovunyelwe ukudlula phezulu, futhi akekho ovunyelwe ukuma ngaphansi kwengalo ye-crane.
4. Akukho ukuhlolwa noma ukulungiswa okuvunyelwe ngenkathi i-crane isebenza.
5. Ezintweni ezinzima eziseduze nomthwalo olinganiselwe, amabhuleki kufanele ahlolwe kuqala, bese ehlolwa ekuphakameni okuncane kanye ne-stroke emfushane ngaphambi kokusebenza kahle.
6. Ukunyakaza kokushayela okubuyela emuva akuvunyelwe.
7. Ngemuva kokuthi ukhreyini usulungisiwe, usulungisiwe, noma kwenzeke ingozi noma umonakalo, ukhreyini kufanele uphumelele ukuhlolwa kwe-ejensi ehlola izinto ezikhethekile futhi uhlolwe ngaphambi kokuthi kubikwe ukuthi usetshenziswa.
