Zomangamanga mawonekedwe ndi makhalidwe a malo grating trestle

Misewu yomwe ilipo kale imakhala yopanda kukongola ndipo imakhala yovuta kusakanikirana ndi chilengedwe, makamaka m'malo okhala ndi chilengedwe. Pofuna kukulitsa moyo wautumiki wa misewu yamtundu wa trestle, pulasitiki ndi zida zina zamakina zimayikidwa pamwamba pa ma pedals, zomwe sizosavuta kuwononga chilengedwe, komanso zimakhudzanso mawonekedwe. Nthawi yomweyo, mphamvu ya msewu wa trestle sungathe kutsimikiziridwa bwino. M'njira yolowera pansi pa grating board imagwiritsa ntchito chitsulo chopepuka ngati poyatsira kuti kuwala kwadzuwa ndi mvula zilowe, zomwe zimapangitsa kuti zomera zapansi zikule bwino. Mapangidwe ake amachepetsanso lateral resonance kuti apititse patsogolo chitonthozo choyenda, chomwe sichimangokhala ndi zotsatira zokongola komanso chimachepetsa mtengo wa polojekitiyi.

Monga zida zomangira zomwe zikubwera, mbale ya grating ikuwonetsa maubwino ake apadera pama projekiti amatawuni. Choyamba, ili ndi makhalidwe okhalitsa, osakonza, mphamvu zambiri, kulemera kwake, kusakhala ndi fumbi, kutulutsa kuwala kwapamwamba, katundu wabwino wotsutsa-slip, ndi kuyika kosavuta ndi kuchotsa, komwe kuli koyenera kwa malo owoneka bwino akunja. Chachiwiri, mbale ya grating ili ndi makhalidwe a kukhazikitsa mwamsanga ndi kuchotsa mwamsanga, zomwe zimathandiza kuteteza chilengedwe cha malo owoneka bwino.

Msewu wa grating plank siwokongola komanso wowoneka bwino, komanso wosavuta kuphatikiza ndi chilengedwe. Ilinso ndi zabwino zamphamvu kwambiri, mphamvu yabwino yothandizira, kusanja kosavuta komanso kukonza, komanso kukana dzimbiri. Msewu wopangidwa ndi zitsulo zopangira matabwa umaphatikizapo thupi la msewu wa thabwa ndi makina oyika omwe amakonzedwa pansi pa denga la msewu. Msewu wa thabwa umaphatikizapo mbale ya grating, mbale yosindikizira, mbale yachitsulo ya konkriti, keel yothandizira ndi pedal. Chosindikizira chosindikizira chimakonzedwa molingana pansi pa malekezero onse a mbale yopangira grating. Chitsulo chachitsulo chimakonzedwa mkati mwa ngodya yomwe imapangidwa pakati pa mbale yosindikizira ndi grating plate, ndipo mbale yosindikizira ndi grating plate imagwirizanitsidwa kupyolera muzitsulo zachitsulo; mbale yachitsulo ya konkire imakonzedwa pansi pa mbale ya grating, ndipo chingwe cha ngalande chimapangidwa pakati pa mbale yachitsulo ya konkire ndi mbale ya grating ndi mbale yosindikizira motsatira. Miyendo yothandizira imagawika mofanana mu gawo la ngalande. Malekezero a ma keel othandizira amalumikizana ndi mbale yachitsulo ya konkriti ndi mbale ya grating motsatana ndikukakamiza mbale ya konkire yachitsulo ndi mbale ya grating motsatana. Madoko a ngalande amatsegulidwa kumapeto onse a mbali imodzi ya pedal, ndipo madoko a ngalande amalumikizidwa ndi kusanjikiza kwa ngalande.
