Ulwakhiwo olusisiseko lwepali yokukhanya yesignali yendlela lwenziwe yipali yokukhanya yesignali yendlela, kwaye ipali yokukhanya yesignali yenziwe yipali ethe nkqo, iflange yokudibanisa, ingalo yokumisela, iflange yokufaka kunye nesakhiwo sentsimbi esifakwe ngaphambili. Ipali yokukhanya yesignali yahlulwe yaba yipali yokukhanya yesignali ye-octagonal, ipali yokukhanya yesignali ye-cylindrical kunye nepali yokukhanya yesignali ye-conical ngokwesakhiwo sayo. Ngokwesakhiwo, ingahlulwa ibe yipali yokukhanya ye-single cantilever, ipali yokukhanya ye-double cantilever, ipali yokukhanya ye-frame cantilever kunye nepali yokukhanya ye-integrated cantilever.
Intonga ethe nkqo okanye ingalo yokuxhasa ethe tye isebenzisa umbhobho wentsimbi othe tye okanye umbhobho wentsimbi ongenamthungo. Isiphelo esidibanisayo sentonga ethe nkqo kunye nengalo yokuxhasa ethe tye senziwe ngombhobho wentsimbi ofanayo nengalo enqamlezileyo, kwaye ikhuselwe yipleyiti yokuqinisa ehlanganisiweyo. Ipali ethe nkqo kunye nesiseko ziqhagamshelwe ngeeflanges kunye neebholiti ezifakwe ngaphakathi, kwaye zikhuselwe ziipleyiti zokuqinisa ze-welding; Unxibelelwano phakathi kwengalo enqamlezileyo kunye nesiphelo sepali ethe nkqo luqhagamshelwe kwaye lukhuselwe ziipleyiti zokuqinisa ze-welding.
Zonke ii-welds zepali ethe nkqo kunye nezinto zayo eziphambili kufuneka zihlangabezane neemfuno ezisemgangathweni, kwaye umphezulu kufuneka ube tyaba kwaye uthambe. I-welding mayibe tyaba, igudileyo, iqine kwaye ithembeke, kwaye ingabi naziphene ezifana nee-pores, i-welding slag kunye ne-false welding. Ipali kunye nezinto zayo eziphambili zinomsebenzi wokukhusela umbane. Isinyithi esingatshajwanga sesibane senza yonke into kwaye siqhagamshelwe kwintambo yokumisa umhlaba nge-grounding bolt ekwiqokobhe. Ipali kunye nezinto zayo eziphambili kufuneka zixhotyiswe ngesixhobo sokumisa umhlaba esithembekileyo, kwaye ukumelana nokumisa umhlaba kufuneka kube yi-≤ 10 Ω.
Indlela yokunyanga ipali yesignali yendlela: intambo yentsimbi kufuneka itsibe ngokuqinileyo emva kwepali yesignali yendlela kwaye ayinakukhululwa. Ngeli xesha, khumbula ukucima umbane okanye ucime umbane oyintloko, uze uyeke ukusebenza. Ngokokuphakama kwepali yokukhanya, fumana i-crane ephezu kwentloko enezikhonkwane ezimbini, lungisa ibhaskithi exhonyiweyo (qaphela amandla okhuseleko), uze ulungise intambo yentsimbi ephukileyo. Khumbula ukuba yonke intambo ayiphukanga, dlula kwiitshaneli ezimbini ukusuka ezantsi kwebhaskithi exhonyiweyo, uze udlule kwibhaskithi exhonyiweyo. Xhoma ihoki kwihoki, kwaye uqaphele ukuba ihoki kufuneka ibe ne-inshurensi yokhuseleko ekuweni. Lungisa ii-interphone ezimbini kwaye uphakamise ilizwi. Nceda ugcine isandi esihle sokufowuna. Emva kokuba umqhubi we-crane enxibelelane nabasebenzi bokulungisa iiphaneli zokukhanya, qala umsebenzi. Nceda uqaphele ukuba abasebenzi bokulungisa isibane se-high pole kufuneka babe nolwazi lombane kwaye baqonde umgaqo wokuphakamisa. Ukusebenza kwe-crane kuya kuba yimfuneko.
Emva kokuba ibhaskithi iphakanyiswe yaya kubude obumiselweyo, umqhubi wokuphakama okuphezulu usebenzisa intambo yocingo ukudibanisa enye ihoko yekreyini kwipleyiti yokukhanya. Emva kokuphakamisa kancinci, ubamba iphaneli yesibane ngesandla sakhe aze ayibeke phezulu, ngelixa abanye besebenzisa isikrufu ukuyikhulula. Emva kokuba ihoko inamathele, beka isixhobo kude, kwaye ikreyini iya kuyiphakamisa ibhaskithi iye kwelinye icala ngaphandle kokuchaphazela ukuphakanyiswa okuqhelekileyo. Ngeli xesha, umqhubi osemhlabeni waqala ukubeka ipleyiti yokukhanya ide iwele phantsi. Abasebenzi abakwibhaskithi bafika phezulu kwepali kwakhona, bahambisa iihoko ezintathu emhlabeni, baze bazipolisha. Sebenzisa igrinder ukuyigquma ngebhotolo kakuhle, uze ufake kwakhona ibholiti yokudibanisa (egalelwe nge-galvanized), uze uyifake kwakhona phezulu kwentonga, uze ujike iihoko ezintathu izihlandlo ezininzi ngesandla ide ithanjiswe ngokukhuselekileyo.
Oku kungasentla lulwakhiwo kunye neempawu zepali yesignali yendlela. Kwangaxeshanye, ndazisa nendlela yokucubungula ipali yesignali yesignali. Ndiqinisekile ukuba uza kufumana into emva kokufunda ezi zinto.
