Nyumba yonyamula katundu ndi gawo la conveyor roller yomwe imagwirizanitsa wodzigudubuza ndi chonyamula chotchedwa "mtima" wa roller.Kutsika kwa mpando wonyamulira kumagwira ntchito yofunika kwambiri panjira komanso kukana kozungulira komanso kozungulira kwa conveyor roller.Ngati malo a nyumba yobereka sakukwaniritsa zofunikira, zingayambitse zizindikiro za kulolerana kwa ma radial odzigudubuza, ndipo chifukwa malekezero onse a digiri ya coaxial si yabwino, zidzachititsa mbali zonse ziwiri za shaft yosiyana.Kusonkhanitsidwa, kudzachititsa wodzigudubuza kuonjezera kukana kasinthasintha wa conveyor wodzigudubuza, osati amachepetsa moyo utumiki, komanso lonse lamba conveyor ntchito mphamvu ukuwonjezeka.Choncho, msonkhano wa lamba wonyamula ndi imodzi mwa njira zofunika kwambiri popanga makina oyendetsa lamba.Kuti athetse vutoli, kuonetsetsa kuti wodzigudubuza wonyamula nyumba udindo ndi mbali ziwiri za digiri coaxial kubala, wopanga ayenera kusankha wodzigudubuza oyenerera ndi zitsulo chubu wodzigudubuza, kusankha kunyamula oyenerera, ndi kubala nyumba.
