Ulwakhiwo olusisiseko lwepali yokukhanya yomqondiso wendlela yenziwe yipali yokukhanya yendlela, kunye nepali yokukhanya yomqondiso yenziwe ngepali ethe nkqo, iflange edibanisayo, ingalo yomfuziselo, iflange exhomayo kunye nesakhiwo sentsimbi esifakwe ngaphambili. Ipali yesibane somqondiso yahlulwe ibe yi-octagonal yesibane sesibane se-octagonal, i-cylindrical signal isibane isibonda kunye ne-conical signal isibane sesibonda ngokwesakhiwo sayo. Ngokwesakhiwo, inokwahlulwa ibe yipali yesignali ye-cantilever enye, i-double cantilever signal pole, i-frame cantilever signal pole kunye ne-pali yesignali edibeneyo ye-cantilever.
Intonga ethe nkqo okanye ingalo yokuxhasa ethe tye ithatha umbhobho wentsimbi womthungo othe tye okanye umbhobho wentsimbi ongenamthungo. Isiphelo sokudibanisa intonga ethe nkqo kunye nengalo yokuxhasa ethe tyaba yenziwe ngombhobho wentsimbi efanayo njengengalo yomnqamlezo, kwaye ikhuselwe ngeplati yokuqinisa i-welded. Isibonda esithe nkqo kunye nesiseko sidibaniswe ngama-flanges kunye neebholiti ezifakwe ngaphakathi, kwaye zikhuselwe ngamacwecwe okuqinisa i-welding; Uqhagamshelo phakathi kwengalo yomnqamlezo kunye nokuphela kwepali ethe nkqo i-flanged kwaye ikhuselwe nge-welding yokuqinisa iipleyiti.
Zonke iintsimbi zepali ezithe nkqo kunye nezixhobo zayo eziphambili ziya kuhlangabezana neemfuno ezisemgangathweni, kwaye umphezulu uya kuba mcaba kwaye ugudileyo. I-welding iya kuba sicaba, igudileyo, iqinile kwaye ithembekile, kwaye ingabi naziphene ezinjengeepores, i-welding slag kunye ne-welding yobuxoki. Ipali kunye namacandelo ayo aphambili anomsebenzi wokukhusela umbane. Isinyithi esingahlanjululwanga sesibane senza yonke into kwaye idibaniswe kwintambo yomhlaba ngokusebenzisa i-bolt grounding bolt kwi-shell. Ipali kunye nezixhobo zayo eziphambili ziya kuxhotyiswa ngesixhobo esithembekileyo sokumisa, kwaye ukuchasana komhlaba kuya kuba ≤ 10 Ω.
Indlela yonyango yepali yomqondiso wezithuthi: intambo yocingo lwentsimbi kufuneka itsibe iqinile emva kwepali yophawu lwezithuthi kwaye ayinakuyekwa. Ngeli xesha, khumbula ukuqhawula unikezelo lwamandla okanye ukucima unikezelo lwamandla oluphambili, kwaye emva koko uyeke ukusebenza. Ngokokuphakama kwepali yokukhanya, fumana i-crane ephezulu kunye neekhonkco ezimbini, lungisa ibhasikidi yokuxhoma (nikela ingqalelo kumandla okhuseleko), uze ulungise intambo yentsimbi ephukileyo. Khumbula ukuba yonke intambo ayiphulwanga, idlule kwiindlela ezimbini ukusuka ngaphantsi kwebhaskiti yokuxhoma, uze udlule kwi-hanger basket. Ukuxhoma hook kwi hook, kwaye unikele ingqalelo ukuba hook kufuneka ibe ne-inshurensi yokhuseleko nxamnye ukuwa. Lungisa ii-interphones ezimbini kwaye unyuse ilizwi. Nceda ugcine umnxeba olungileyo rhoqo. Emva kokuba umqhubi we-crane eqhagamshelana nabasebenzi bokugcina ipaneli yokukhanya, qalisa umsebenzi. Nceda uqaphele ukuba abasebenzi bokulondoloza isibane esiphezulu kufuneka babe nolwazi lombane kwaye baqonde umgaqo wokuphakamisa. Umsebenzi weCrane uya kuba nesiqinisekiso.
Emva kokuba ibhaskithi iphakanyiselwe kubude obumiselwe kwangaphambili, umqhubi wobude obuphezulu usebenzisa intambo yocingo ukudibanisa enye ihuku yekhrane kwipleyiti yokukhanya. Emva kokuphakamisa kancinane, ubamba isibane ngesandla aze asijongele phezulu, ngoxa abanye besebenzisa isitshixo ukusikhulula. Emva kokuba i-hook ibambelele, beka isixhobo kude, kwaye i-crane iya kuphakamisa ibhasikidi kwelinye icala ngaphandle kokuchaphazela ukuphakanyiswa okuqhelekileyo. Ngeli xesha, umqhubi emhlabeni waqala ukubeka phantsi ipleyiti yokukhanya de yawa phantsi. Intonga ekwingobozi yeza phezu kwepali kwakhona, yawabuyisela amagwegwe amathathu emhlabeni, yaza yawakhazimlisa. Sebenzisa i-grinder ukuze uyiqabe ngebhotolo kakuhle, uze uphinde ufake ibholithi yokudibanisa (i-galvanized), uze uphinde uyibuyisele phezu kwentonga, kwaye ujike amagwegwe amathathu amatyeli aliqela ngesandla de ithanjiswe ngokukhuselekileyo.
Oku ngasentla kubume kunye neempawu zepali ye-traffic signal. Ngelo xesha, ndazisa kwakhona indlela yokucubungula isibane sesibane somqondiso. Ndiqinisekile ukuba uya kufumana into emva kokufunda le mixholo.
