Thekaviri girder pamusoro pecraneinorema-basa rekusimudza mhinduro inowanzoshandiswa mumaindasitiri anoda yakasimba, yakakwirira-inogonesa kubata zvinhu. Rudzi urwu rwe crane ine magidhi maviri akafanana anotenderera pahupamhi hwenzvimbo yekushandira, achipa kugadzikana kukuru uye kutakura mutoro wekutakura kupfuura single-girder cranes. Aya macranes epamusoro akanakira maapplication akadai sekugadzira simbi, kubatanidza mota, kuvaka ngarava, uye dzimwe nzvimbo dzinodiwa zvakanyanya uko kurongeka uye kusimba kwakakosha.
Paunenge uchifunga zvinorema-basa rekusimudza mhinduro, kunzwisisa iyokaviri girdereot mutengo we cranekwakakosha pakuita bhajeti rezvirongwa zvemaindasitiri makuru.
Chimiro che akaviri girder pamusoro pecranekazhinji zvinosanganisira:
Magidhi maviri: Magidhi maviri ekutanga anotakura mutoro, achipa crane mukana wepamusoro wekusimudza zvinhu zvinorema.
Marori Anopera: Anowanikwa kumagumo emagirders, aya anofambisa kufamba achitevedza kaviri girder eot crane's runway, achigonesa kufamba kwakachinjika munzvimbo yebasa.
Hoist neTrolley: Yakaiswa pakati pemagidhi maviri, hoist uye trolley inofamba pamwe nepakati pemagidhi, ichigonesa yakatwasuka uye yakachinjika mitoro kufamba.
Magetsi Mota uye Kudzora System: Iyokaviri girder eot cranekufamba, kusimudza, uye mamwe mabasa anodzorwa kuburikidza nemota yemagetsi, kazhinji ine remote kana redhiyo redhiyo kuitira kushanda kwakachengeteka uye nemazvo.
Thekaviri girdereot mutengo we craneinogona kusiyanisa zvakanyanya zvichienderana nekutsanangurwa senge mutoro wekuremerwa, span, uye kugadzirisa sarudzo.
Nguva dzose kuchengetedza kwezvikamu zve crane-senge hoist, control system, uye chimiro chechimiro-yakakosha pakushanda kwakachengeteka uye kwakanaka. Zvirongwa zvekuchengetedza zvinofanirwa kusanganisira kuongororwa kwemota, mabhureki masisitimu, uye zvikamu zvinotakura zvinhu kuti ive nechokwadi chekuvimbika uye kudzivirira kuparara kusingatarisirwe.
