Njengamanje, iningi lama-pulleys endabuko emakethe ayinsimbi ekhonjiwe noma insimbi, ebizayo futhi eyinkimbinkimbi ekusebenzeni, futhi izindleko zangempela ziphakeme kakhulu kunalezo.amapulangwe enayiloni.Imikhiqizo enayiloni inomthamo oqinile wokuthwala, kodwa ukumelana nokugqokwa okungekuhle futhi igqokwa kalula ngezintambo zensimbi.

Kodwa futhi singashintsha izilinganiso ukuze sikhiqize amapulangwe enayiloni asebenza kangcono.Ngemuva kokusebenzisa i-nylon pulley entsha, impilo yesevisi ye-pulley ingandiswa izikhathi ezine kuya kweziyisihlanu, futhi impilo yesevisi yentambo yensimbi yensimbi ingandiswa cishe izikhathi eziyishumi.

Uma kuqhathaniswa ne-cast iron pulleys,amapulangwe enayilonizilula ngo-70% futhi zandisa ukusebenza kahle kokukhiqiza.Ngesikhathi esifanayo, iphinde ithuthukise ukusebenza okuphelele komshini, okulungele ukugcinwa, ukuhlakazeka nokuhlanganisa ngaphandle kwamafutha okugcoba.

Amasondo enayilonibabe nezici zokungabi bikho kwezinhlansi zokungqubuzana nokusebenza okuqinile kokuphepha, okungahlangabezana nezidingo zokusebenza kwangaphandle kwesikhathi eside.

Kusukela ngeminyaka yawo-1970s, abakhiqizi abaningi be-crane bangaphandle baye bamukela ama-pulley enayiloni njengezinsiza eziyisisekelo zama-cranes.Njengamanje, inkampani yethu ayinawo ama-pulleys afanele ama-cranes kuphela, kodwa futhi nemikhiqizo eminingi ye-nylon efanelekile kwezinye izimboni, eyamukelwa kahle yizinkampani eziningi emakethe.

Inayiloni imelana nokuhuzuka futhi ayinciphisi kuphela isisindo sisonke sedivayisi, kodwa futhi ivikela futhi isekele izindawo zensimbi.Okwamanje,amapulangwe enayiloniziye zasetshenziswa kabanzi ekuphakamiseni imishini efana nemikhumbi namakheshi.
