I-dual lead worm kunye nevili lentshulube luhlobo lwenkqubo yegiya esetyenziselwa ukuhanjiswa kwamandla. Ibandakanya intshulube, eyi-screw-like cylindrical component enamazinyo e-helical, kunye nevili leentshulube, eliyigiya enamazinyo adityaniswa nombungu.

Igama elithi “dual lead” libhekisela kwinto yokuba lo mbungu unamazinyo amabini, okanye imisonto, ejikeleza umbhobho kwii-engile ezahlukeneyo. Olu yilo lubonelela ngomlinganiselo ophezulu wegiya xa kuthelekiswa nomsundululu omnye, nto leyo ethetha ukuba ivili lentshulube liza kujikeleza amaxesha amaninzi kwi revolution yombungu.

Inzuzo yokusebenzisa i-dual lead worm kunye nevili lentshulube kukuba inokufikelela kumlinganiselo omkhulu wegiya kwi-compact design, iyenze ibe luncedo kwizicelo apho indawo incinci. Ikwayazitshixa, nto leyo ethetha ukuba intshulube iyakwazi ukulibamba ivili leentshulube ngaphandle kwemfuneko yesiqhoboshi okanye enye indlela yokutshixa.

Iinkqubo ezimbini zeentshulube ezikhokelayo kunye nevili leentshulube ziqhele ukusetyenziswa koomatshini kunye nezixhobo ezifana neenkqubo zokuhambisa, izixhobo zokunyusa, kunye nezixhobo zoomatshini.
