Ityhefu ebizwa ngokuba sisidumbu esiqinileyo. Akukho ntambo isetyenziswa njenge-skeleton, ngoko akukho mfuneko yokufaka itayara, kwaye akukho sidingo sokugcwalisa ityhubhu yangaphakathi okanye i-liner engaphakathi. Amatayara okuqala ayeneetayara eziqinileyo.
Amatayara aqinileyo ahlulwe ikakhulu kwiindidi ezimbini: amatayara aqholiweyo kunye namatayara angowabinayo. Yakuqala kubhekiswa kumatayara achithwe ngokuthe ngqo kwaye axhonywe emgceni, kwaye okulandelayo kubhekisa kumatayara ahleliweyo aze axhonywe emgqomeni.
Ngokutsho kokuhlelwa kobume, zimbini iintlobo zamatayara aqinileyo anemigangatho esezantsi ye-on efanelekileyo kunye neetayile eziqinileyo ze-cylindrical; Ukuba yahlulwe ngenjongo, kukho amatayara e-oyile, enomthwalo oqinileyo, ongenakumakisha okumangalisayo, i-antistatic, eqhuba, njl.
Ukusebenza kwetayara eqinileyo: Amatayara aqinileyo anezinto zokuhlaselwa kobushushu, ukuqina okuphezulu kwaye anxibe ukunganyangeki, uzinzo olungcono, indawo enkulu yoqhakamshelwano, kwaye yomelele.
Imisebenzi eqinileyo yetayara: Amavili aqinileyo anobomi obude, ireyithi yokuphuhlisa, ifuthe elincinci kwi-forklift, incitshiswe iindleko ze-forklift, kwaye yanda intuthuzelo yomqhubi.
