Isithwali se-Girder esilungisiwe/Isithwali se-Beam

I-girder transporter iyimoto ekhethekile esindayo eyenzelwe ukuthutha ama-girder amakhulu kanye nemishayo esetshenziswa ekwakheni, kumaphrojekthi engqalasizinda, kanye nasezisetshenzisweni zezimboni. Ama-girder ayizingxenye ezibalulekile ekwakheni amabhuloho, izitimela, kanye nezakhiwo ezinkulu, futhi ukuthuthwa okuphephile nokuphumelelayo kwalezi zingxenye ezinkulu kubalulekile ekuqedeni amaphrojekthi anjalo ngesikhathi nangempumelelo. Ama-girder transporter aklanywe ukuze aphathe isisindo esikhulu kanye nosayizi walezi zingxenye ngenkathi egcina amazinga aphezulu okuqina kanye nokuphepha ngesikhathi sokuthutha.

Esinye sezici ezibalulekile zabathuthi begirder ukuthi bayakwazi ukuthwala umthwalo omningi, ngokuvamile abakwazi ukuthutha amagirder anesisindo esingamathani angamakhulu amaningana. Laba bathuthi bahlonyiswe ngezinhlelo zokumiswa kwe-hydraulic ezisiza ekusabalaliseni umthwalo ngokulinganayo kuma-axle amaningi, okuqinisekisa ukunyakaza okubushelelezi kwemithwalo esindayo ngisho nasezindaweni ezingalingani. Lokhu kumiswa kuthuthukisa nokuguquguquka, okuvumela umthuthi ukuthi ahambe ezindaweni ezixineneyo nasezindaweni zomsebenzi eziyinkimbinkimbi ngaphandle kokubeka engcupheni ukuphepha.

Ngaphezu kwamakhono azo okuthwala imithwalo, abathuthi begirder bavame ukuza nemiklamo ye-modular, okuvumela ukuthi bavumelane nobukhulu obuhlukene begirder kanye nezimo. Uhlobo lwe-modular lwalaba bathuthi lubenza bakwazi ukuguquguquka ngokwanele ukuphatha izinto zokwakha ezahlukahlukene, kusukela emishayweni yensimbi kuya kuma-girder ekhonkrithi.

Ukuphepha kuyisici esibalulekile sokuthuthwa kwe-girder, futhi iningi labathuthi lihlonyiswe ngezinhlelo zokubhuleka ezithuthukisiwe, izindlela zokuqondisa ezenzakalelayo, kanye nezinhlelo zokuqapha ngesikhathi sangempela ukuqinisekisa ukuthi i-girder iboshwe kahle futhi izinzile phakathi nohambo lwayo. Lezi zici zinciphisa izingozi futhi ziqinisekisa ukuthi i-girder ilethwa ngokuphephile nangendlela efanele lapho iya khona.

Ngamafuphi, abathuthi begirder babalulekile ekuthuthukisweni kwengqalasizinda yesimanje, banikeza amandla aphezulu, ukuguquguquka, kanye nokuphepha ekuthuthweni kwegirder ezinkulu nezisindayo ezibalulekile kumaphrojekthi okwakha amakhulu.
