Wiishka Gantry waxaa loo isticmaalaa inta badan dhanka macdanta, wax soo saarka guud, shubka, dhismaha, iyo sidoo kale meelaha lagu raro hawo furan iyo bakhaarrada si loo xakameeyo xamuulka badan. Wiishka gantry-ga ah ee hal-geeska ah ayaa guud ahaan loo arkaa inuu yahay nooc khafiif ah oo ah wiishka gantry sababtoo ah naqshadaynta qaab-dhismeedka oo leh hal bir oo keliya, ayaa si weyn loogu isticmaalaa goobaha hawada furan sida deyrarka alaabta, goobaha shaqada, bakhaarada alaabta rarka iyo dejinta. Wiishashka gantry-ga hal-geeska ah waa wiish caadi ah oo loogu talagalay maaraynta walxaha guud, oo inta badan lagu isticmaalo goobaha bannaanka, bakhaarrada, dekedaha, warshadaha granite, warshadaha tuubooyinka sibidhka, deyrar furan, bakhaarrada haamaha lagu kaydiyo, iyo barxadaha maraakiibta, iwm. Si kastaba ha ahaatee, waa mamnuuc la tacaalida birta dhalaalaysa, ololi kara, ama walxaha qarxa. Crane-gantry-ga noociisa ah ee hal-geeska ah waa cabbir dhexdhexaad ah, wiish-socod-raac, guud ahaan ku qalabaysan koronto-qaade MD-ga caadiga ah sida kor-qaade, oo leh wiish koronto ah oo dul-maray I-birta hoose ee girder weyn, oo laga sameeyay saxan bir ah. , kaas oo laga sameeyay saxan bir ah, sida C-steel, iyo saxan birta dahaarka ah, iyo I-steel.
SEVENCRANE waxay bixisaa noocyo kala duwan oo gantry wiish ah, sida, dhamaystiran iyo semi-dhamaystiran gantry marka la eego qaab-dhismeedka cagta, gantry weel, gantry gantry, dockside gantry, dockside gantry, dockside gantry, dockside gantry, marka la eego codsiyada. Marka lagu daro wiishashka gantry-ga halliga ah ee caadiga ah ee aan kor ku soo xusnay, SEVENCRAN -E waxay naqshadaysaa oo soo saartaa wiishyada gantry-ga moobilka ee kala duwan ee codsiyada warshadaha kala duwan, oo ay ku jiraan gantry koronto oo wata caag-kaliya nooca loo yaqaan 'hydraulic'.
Marka si sax ah loo nashqadeeyo, wiishashka hal-geeska ah ayaa kordhin kara wax-soo-saarka maalinlaha ah, iyadoo siinaya xalka ugu fiican ee tas-hiilaadka iyo hawlgallada kuwaas oo leh meel bannaan oo sagxad ah iyo baahiyaha nadiifinta dusha sare ee wiish hawl-fulin-ilaa-dhex-dhexaad ah. Sababtoo ah waxay u baahan yihiin hal bir oo kaliya si ay u maraan, nidaamyadani guud ahaan waxay leeyihiin miisaan dhimis oo hooseeya, taasoo la micno ah inay ka faa'iidaysan karaan hababka raadraaca fudud oo ay ku xidhaan dhismayaasha jira ee taageeraya dhismayaasha. Dhisidda wiishashka sagxadda hoose waxay u oggolaanaysaa nidaamyada jeexjeexyada, kaas oo looga baahan yahay wareejinta rarka ee hal gacan oo loo wareejiyo mid kale, ama iyada oo lagu wareejinayo monorails, ka dibna wiish kale, ama xabbad-joojin.
