Choyamba, malo a bolodi la guardrail anganenedwe kuti amakhudza mwachindunji mawonekedwe a kukhazikitsa ndi kumanga kwa guardrail yothamanga kwambiri, kotero aliyense ayenera kudziwa bwino njira yoyenera yoyikira mzatiyo malinga ndi zojambula zomangira, kuti athandize guardrail mtsogolo.

Chachiwiri, pa masitepe okhazikitsa mzati, masitepe otsatira omanga amatha kuchitika pokhapokha ngati phewa la nthaka lalimbikitsidwa.

Chachitatu, pomanga ndi kukhazikitsa pulojekiti yayikulu, akatswiri ayenera choyamba kuthana ndi ma flange ndi mabolts a nangula kuti akhazikitse mizati yoyenera.

Chachinayi, zida zotetezera zingwe zothamanga kwambiri komanso kukhazikitsa zingwe zotetezera ziyenera kukonzedwa kuti zimangidwe pasadakhale, kuwunika ngati zipangizo zopangira zatha, komanso ngati magwiridwe antchito a zida ndi zida akukwaniritsa miyezo yomwe yatchulidwa.

Chachisanu, poika ma guardrails a Jinggong Technology Expressway, ndikofunikira kudziwa bwino zinthu zosiyanasiyana komanso momwe malo alili, ndi zina zotero, makamaka malo enieni a mapaipi okhala ndi zinthu zosiyanasiyana zomwe zaikidwa pa roadbed, onetsetsani kuti mwatsimikiza bwino.

Chachisanu ndi chimodzi, pomanga njanji yothamanga kwambiri, kumbukirani kuti musawononge zinthu zapansi panthaka mosiyanasiyana, ndipo onetsetsani kuti mwatenga mizati moyenera malinga ndi zojambula zomwe zapangidwa kale, kukhazikitsa malo owongolera m'malo osiyanasiyana, ndikuyika malo osiyanasiyana.

Chachisanu ndi chiwiri, pamene mizati yonse yayikidwa, akatswiri omanga oyenerera ayeneranso kuyang'ana momwe maziko a mzati uliwonse alili kuti awone ngati akukwaniritsa miyezo yomwe yaperekedwa.

Chachisanu ndi chitatu, ndikofunikira kudziwa njira yokhazikitsira mzati, kaya wayikidwa kale kapena wayikidwa pa chassis, chinthu chofunikira kwambiri ndikusunga mkhalidwe wokhazikika, ndipo sipayenera kukhala kugwedezeka ndi kusasunthika, chifukwa ngati chipangizo chotere sichinayikidwe bwino, sichidzangomasuka pambuyo pogwiritsidwa ntchito kwa nthawi yayitali, komanso chingayambitse mavuto monga kusintha kwa mawonekedwe.

Popeza kubwera kwa zaka za m'ma 2000, msewu waukulu wakhala umodzi mwa malo ofunikira kwambiri omwe timakumana nawo tsiku lililonse. Kukhalapo kwa njanji yothamanga kwambiri ya Jinggong Technology kungatithandize kukhala otetezeka kwambiri pamsewu woyendetsa.
