Ngokuthuthuka okuqhubekayo kwamazinga okukhiqiza kanye nemvelo, okokusebenza kokushisisa nokupholisa izingosi zokugcina sekuyizinto ezisetshenziswayo ezijwayelekile zamabhizinisi amaningi. Ingxenye yekhethini yomnyango osheshayo we-zipper ayinazo izingxenye zensimbi zokuqinisekisa ukuphepha kwemishini kanye nabasebenzi, futhi umnyango we-zipper onesivinini esikhulu unokusebenza okuhle kakhulu kokumelana nokuzibamba. Ngesikhathi esifanayo, inomsebenzi wokuzilungisa, ngisho noma ikhethini lomnyango liphazamisekile (njengokushaywa i-forklift, njll.), ikhethini lizophinde lilandele ngokuzenzakalelayo emjikelezweni olandelayo wokusebenza.
