Isisekelo senqwaba singakhethwa ezimweni ezilandelayo

1. Isisekelo senqwaba singasetshenziswa lapho isisekelo sibuthakathaka futhi isisekelo semvelo asikwazi ukuhlangabezana nezidingo zamandla esisekelo kanye nokuguqulwa.

2, lapho kunezidingo eziqinile zokwakhiwa kwesakhiwo, isisekelo senqwaba kufanele sisetshenziswe.

3. Isisekelo senqwaba kufanele sisetshenziswe lapho izakhiwo eziphakeme noma izakhiwo zinezidingo ezikhethekile zokunciphisa ukutsheka.

4. Isisekelo senqwaba kufanele sisetshenziswe lapho isisekelo sokuhlala sinomthelela ofanayo ezakhiweni eziseduze.

I-5, isitshalo sezimboni esindayo esinesitezi esisodwa esine-tonnage enkulu esindayo, umthwalo we-crane mkhulu, ukusetshenziswa njalo, isiteji semishini yokusebenzela, isisekelo esiminyene, futhi ngokuvamile sinomthwalo ophansi, ngakho-ke ukuguqulwa kwesisekelo kukhulu, bese isisekelo senqwaba singasetshenziswa.

6, ukunemba imishini isisekelo namandla mechanical isisekelo, ngenxa deformation kanye amplitude evunyelwe banezidingo ephakeme, ngokuvamile futhi esetshenziswa inqwaba isisekelo.

I-7, indawo yokuzamazama komhlaba, esisekelweni esingancibilika, ukusetshenziswa kwesisekelo senqwaba ngokusebenzisa ungqimba lwenhlabathi e-liquefiable futhi lunwebe ungqimba lwenhlabathi oluqinile oluphansi, lungaqeda noma lunciphise umonakalo wokukhipha uketshezi esakhiweni.
