Kodi ziwalo za choyambitsa girder ndi ziti?

Thecrane yoyambira gantryndi chipangizo chofunikira chomwe chimagwiritsidwa ntchito popanga milatho pomanga ndikuyika ma girders a milatho. Ndi makina apadera opangidwa kuti anyamule, kunyamula ndikuyika ma girders olemera a milatho pamalo ake, zomwe zimapangitsa kuti ikhale gawo lofunika kwambiri pakupanga milatho.

Choyimitsa cholumikizira cholumikizira chimakhala ndi zigawo zingapo zofunika zomwe zimagwirira ntchito limodzi kuti zitsimikizire kuti zolumikizira zolumikizira mlatho zikhazikike bwino komanso motetezeka. Chimodzi mwa zigawo zazikulu ndi mtanda waukulu, womwe ndi gawo lalikulu la choyatsira. Mtanda waukulu umayang'anira kulemera kwa mtanda waukulu wa mlatho ndikupereka kukhazikika pakukweza ndi kutsitsa.

Chinthu china chofunikira kwambiri pa choyatsira nyali chachikulu ndi mutu woyambitsa, womwe uli kutsogolo kwa nyali yayikulu. Mutu wotumizira uli ndi zida zapadera monga ma hydraulic jacks ndi zida zonyamulira kuti zinyamule bwino ndikuyika ma girders a mlatho. Ulinso ndi truss yoyambitsa yomwe imapereka chithandizo chowonjezera komanso kukhazikika panthawi yoyambitsa.

Dongosolo loletsa kulemera ndi gawo lina lofunika kwambiri la choyatsira nyali ndipo lapangidwa kuti ligwirizane ndi kulemera kwa mlatho ndi choyatsira chokha. Dongosololi limaonetsetsa kuti choyatsira chikhale chokhazikika komanso chotetezeka pokweza ndikuyika magirders, kuchepetsa chiopsezo cha ngozi kapena kuwonongeka kwa kapangidwe kake.

Kuphatikiza apo, choyatsira beam chili ndi makina owongolera apamwamba omwe amalola woyendetsa kuti aziyang'anira ndikusintha njira yokwezera ndi kutsegulira. Makina owongolerawa amaphatikizapo zida zamagetsi ndi zamagetsi zomwe zimathandiza kuyenda molondola komanso mowongoleredwa kuti zitsimikizire kuyika bwino komanso kotetezeka kwa mipiringidzo ya mlatho.

Mwachidule, chokwezera mlatho ndi chida chovuta kwambiri chomangira mlatho chomwe chili ndi zinthu zingapo zofunika zomwe zimagwirira ntchito limodzi kukweza, kunyamula ndi kuyika mipanda ya mlatho panthawi yomanga mlatho. Kapangidwe kake katsopano komanso ukadaulo wapamwamba zimapangitsa kuti ikhale chida chofunikira kwambiri pamapulojekiti omanga mlatho, zomwe zimathandiza kuti mipanda ya mlatho ikhazikike bwino komanso motetezeka.
