Ndi mitundu yanji ya bollard yokweza yomwe ilipo?

Mabodi okwezanthawi zambiri amatanthauza zida zomwe zimagwiritsidwa ntchito kunyamula ndi kutsitsa katundu kapena magalimoto. Malinga ndi kagwiritsidwe ntchito kawo ndi kapangidwe kawo, zitha kugawidwa m'mitundu yambiri, kuphatikiza koma osati kokha:

Mabodi okweza a hydraulic:Kupanikizika komwe kumaperekedwa ndi makina a hydraulic kumapangitsa kuti bollard ikwere kapena igwe, yomwe imagwiritsidwa ntchito kunyamula magalimoto kapena zinthu zolemera.

Mabodi okweza magetsi:Yoyendetsedwa ndi mota yamagetsi kuti ikwaniritse ntchito zonyamula, zomwe zimagwiritsidwa ntchito kwambiri m'ma desiki onyamula magetsi, makina oimitsa magetsi, ndi zina zotero.

Mabowolo okweza ozungulira:Kukweza kumachitika kudzera mu kutumiza kozungulira, komwe nthawi zambiri kumagwiritsidwa ntchito kusintha kutalika kwa matebulo ndi mipando kapena kugwiritsidwa ntchito m'mafakitale apadera, monga matebulo ogwirira ntchito.

Mabowolo okweza a pneumatic:Gwiritsani ntchito mpweya woperekedwa ndi makina opopera mpweya kuti muwongolere kukweza, ndipo nthawi zambiri amagwiritsidwa ntchito pokweza zida m'mafakitale opanga zinthu kapena m'malo apadera.

Mabokosi onyamulira ndi manja:Ntchito zonyamula katundu zimapezeka pogwiritsa ntchito manja, monga ma hydraulic jacks amanja.

Izi zonse ndi mitundu yodziwika bwino yazonyamulira mabodi, ndipo chisankho chenichenicho chimadalira zofunikira zenizeni zogwiritsira ntchito komanso momwe zinthu zilili.
