I-Ladder uhlobo lwemishini yokuzivocavoca yangaphandle, evame ukuvela ezikoleni, emapaki, ezindaweni zokuhlala, njll; Izigaba ezijwayelekile zihlanganisa iladi elimazombezombe, ileli lohlobo lwe-C, ileli lohlobo lwe-S kanye nesitebhisi sokugibela ngesandla. Abantu bathanda lolu hlobo lwemishini yokuzivocavoca yangaphandle, hhayi nje ngenxa yesimo sayo esiyingqayizivele, kodwa nangenxa yomphumela wayo wokuqina ophawulekayo. Kungakhathaliseki ukuthi ukushintsha kuyini, iladi lingasebenzisa amandla emisipha yamalungu angaphezulu futhi lithuthukise ikhono lokubamba lezandla zombili. Ngaphezu kwalokho, uma le mishini ivame ukusetshenziswa, isihlakala, indololwane, ihlombe namanye amalunga nawo angaguquguquka. Ngaphezu kwalokho, imiklamo ehlukene yeladi nayo ingathuthukisa ukusebenzelana komzimba womuntu. Umphakathi jikelele ungasebenzisa iladi ukuze uhlale ulungile.
Ukusetshenziswa kwamashubhu ayisikwele kwenza izinsimbi ziqine, zibe zinhle futhi ziqine, futhi zingakwazi ukumelana nesisindo esikhulu.
Umsebenzi:
1. Khulisa ukujikeleza kwegazi emzimbeni futhi ukhuthaze umzimba;
2. Thuthukisa amandla ezitho ezingaphezulu kanye nokuguquguquka kokhalo nesisu, uthuthukise amandla okuthwala amajoyinti ehlombe, futhi usebenzise ibhalansi nokuxhumana.
3. Inqubo yokufafaza nge-electrostatic yamukelwa ngopende wokubhaka.
4. Ukukhethwa kwemibala ye-cushion neshalofu kumahhala, futhi ungakhetha imibala ehlukene.
