Zvivako zvikuru zvesimbi zvikamu zvakakosha muindasitiri yekutumira zvinhu sezvo zvichikurumidzisa kutamiswa kwezvinhu, zvichiita kuti zvikwanisike kutakura zvinhu zvakawanda munguva pfupi.

Izwi rekuti 'port crane' rinoreva chero mudziyo unorema unoshandiswa muchiteshi chekutakura zvinhu kana chiteshi chekutakura zvinhu kuti ubate makontena, zvinhu, nezvimwe zvinhu zvakakura. Anouya mumhando dzakasiyana-siyana, saizi uye kugona, uye akagadzirwa kuti abate mhando dzakasiyana dzezvinhu zvinotakura. Mamwe emhando dzakajairika dzeport crane dzinosanganisira magantry crane, magantry crane ane mataira erabha, macrane engarava, uye macrane ane tambo dzechitima.

Macrane eGantry ndiwo mhando yemacrane anonyanya kuwanikwa muzviteshi zvemazuva ano. Izvivako zvikuru zvinoshanda panjanji uye zvinogona kutakura zvinhu zviri mumakontena kubva pachiteshi kuenda kune chimwe kana chimwe. Macrane eGantry anouya mumhando dzakasiyana-siyana uye saizi, ane urefu hwemaboom hunobva pamamita makumi maviri kusvika pamamita zana nemakumi maviri. Macrane aya anoshandisa mota dzemagetsi dzine simba kusimudza makontena anorema kusvika kumatani zana zviri nyore.

Kune rumwe rutivi, macrane erabha ane mataira akafanana nemacrane erabha kunze kwekuti anoshanda pamatairi erabha panzvimbo pematrack. Anofamba zvakanyanya uye anogona kutakura zvinhu muchiteshi zviri nyore, zvichiita kuti ashande zvakanaka kana zvasvika pakurongedza nekutamisa macontainer.

Makireni engarava, anozivikanwawo semakireni epadivi pechiteshi, anoshandiswa kurodha nekuburitsa ngarava dzakakura zvakanyanya kuti dzisakwanise kumira pamhenderekedzo. Makireni aya anotambanudza kubva pachiteshi osimudza magaba zvakananga kubva muchikepe kuenda kumarori kana zvitima zvakamirira pamucheto wechiteshi.

Makireni anokwidzwa muchitima anoshandiswa muzviteshi zvine nzira yekufambisa zvinhu mukati menyika. Akagadzirirwa kutamisa makontena kubva muchikepe kuenda kuchitima uye anogona kusimudza makontena anorema kusvika matani makumi mana rimwe nerimwe.

Makireni epachiteshi akavakwa kuti agone kutsungirira mamiriro ekunze akaoma uye akagadzirwa nesimbi yakasimba kuti ave nechokwadi chekugadzikana uye kuvimbika. Makireni emazuva ano ane tekinoroji yepamusoro uye masensa ekuvandudza kuchengetedzeka uye kushanda zvakanaka kwemabasa epachiteshi. Ane hushamwariwo nezvakatipoteredza, ane simba shoma rinoshandiswa uye utsi hunobva mumhepo, zvichiita kuti ave akakodzera makireni emazuva ano.

Mukupedzisa, kireni yechiteshi chinhu chakakosha muindasitiri yekutakura zvinhu nekutakura zvinhu. Ndiyo inorema inosimudzira madoko uye zvinhu zvichifamba. Nekuuya kwetekinoroji yepamusoro, mhando itsva dzekireni dzechiteshi dzinoshanda zviri nani uye dzisingakuvadzi nharaunda dzicharamba dzichibuda, zvichichinja indasitiri zvakanyanya. Kunyange zvazvo remangwana reindasitiri yekutakura zvinhu risingafungidzike, chimwe chinhu chine chokwadi ndechekuti kireni yechiteshi icharamba isingatsiviwe.
