Mu 10 mbere ya Yesu, umwubatsi wa kera w’Abaroma Vitruvius yasobanuye imashini iterura mu gitabo cye cyubaka.Iyi mashini ifite mast, hejuru yikinini ifite pulley, umwanya wikibanza ushyirwaho numugozi ukurura, kandi umugozi unyura muri pulley ukururwa na winch kugirango uzamure ibintu biremereye.
Mu kinyejana cya 15, Ubutaliyani bwavumbuye jib crane kugirango ikemure iki kibazo.Crane ifite cantilever yegeranye ifite pulley hejuru yukuboko, ishobora kuzamurwa no kuzunguruka.
Hagati yikinyejana cya 18 na nyuma yikinyejana cya 18, watt imaze gutera imbere no guhimba moteri ya parike, yatanze ingufu zamashanyarazi.Mu 1805, injeniyeri wa Glen Lenny yubatse icyiciro cya mbere cyamazi ya parike ya Londere.Mu 1846, Armstrong wo mu Bwongereza yahinduye icyuma cy’amazi muri docast ya Newcastle ahinduka hydraulic crane.
Mu ntangiriro z'ikinyejana cya 20, Crane umunara yakoreshejwe mu Burayi,
Crane ikubiyemo cyane cyane uburyo bwo guterura, uburyo bwo gukora, uburyo bwa luffing, uburyo bwo guswera hamwe nicyuma.Uburyo bwo guterura nuburyo bwibanze bwakazi bwa crane, bugizwe ahanini na sisitemu yo guhagarika na winch, kimwe no guterura ibintu biremereye binyuze muri hydraulic.
Uburyo bukoreshwa bukoreshwa mu kwimura ibintu biremereye birebire kandi bitambitse cyangwa guhindura imyanya ikora ya kane.Mubisanzwe bigizwe na moteri, kugabanya, feri niziga.Uburyo bwa luffing bufite ibikoresho gusa kuri jib crane.Amplitude igabanuka iyo jib yazamutse kandi ikiyongera iyo yamanuwe.Igabanijwemo kuringaniza no kuringaniza.Uburyo bwo guswera bukoreshwa mukuzunguruka ibimera kandi bigizwe nigikoresho cyo gutwara hamwe nigikoresho cyo gutwara.Imiterere yicyuma ni urwego rwa kane.Ibice byingenzi bifata nk'ikiraro, boom na gantry birashobora kuba agasanduku k'imiterere, imiterere ya truss cyangwa imiterere y'urubuga, kandi bamwe bashobora gukoresha ibyuma by'igice nk'igiti gishyigikira.
