Ingaba ikhonkco lesandla lisisixhobo esikhethekileyo?

Izixhobo ezikhethekileyo zibhekisela kwizixhobo zokusebenza ezibandakanya inkxaso yobomi kwaye ziyingozi kakhulu. Izixhobo ezikhethekileyo zihlulwe zibe ngamacandelo amabini: izixhobo ezikhethekileyo ezithwele uxinzelelo kunye nezixhobo ezikhethekileyo ze-electromechanical. Kumashishini okunyusa, kuyacaca ukuba yeyezixhobo ze-electromechanical. uhlobo lwezixhobo ezizodwa. Izixhobo ezikhethekileyo ze-electromechanical zisetyenziselwa ukuphakamisa ngokuthe nkqo okanye izixhobo ze-electromechanical eziphakamisa ngokuthe nkqo kwaye zihambisa izinto ezinzima ngokuthe tye. Ukuchazwa ngakumbi, ububanzi balo buchazwa njengento yokunyuswa kunye nomthamo ophakanyisiweyo ophakamileyo okanye olingana no-0.5t kunye nomthamo ophakanyisiweyo wokuphakamisa umlinganiselo omkhulu okanye ulingana ne-3t kunye nokuphakama kokuphakama okukhulu kunokuba Okanye i-crane elingana ne-2m; ukusuka kule ngcaciso ingentla, sinokubona ukuba i-chain hoist ayisona sixhobo esikhethekileyo. Nika ingqalelo kwigama elithi "electromechanical", elithetha ukuba kufuneka liqhutywe "ngombane". Oko kukuthi, into ebizwa ngokuba yi-electric hoist, i-crane, njl. Ulwazi olungentla lubonisa kuphela ngokuthetha ukuba i-chain hoist ayisona isixhobo esikhethekileyo. Nangona imimiselo ithi, kwezinye iindawo zelizwe, ichain hoistisithathwa njengesixhobo esikhethekileyo kwaye kufuneka sihlolwe minyaka le.
