Kapangidwe kake ka ma sign pole light pole amapangidwa ndi ma light pole a pamsewu, ndipo chizindikiro chowunikira chimapangidwa ndi chitsulo choyimirira, cholumikizira cha flange, mkono wofananira, flange wokwera ndi kachipangizo kachitsulo kamene kamayika kale. Mzati wa nyali wamakina amagawidwa mumtengo wa nyali ya octagonal, cylindrical chizindikiro cha nyali ndi mtengo wanyali wa conical malinga ndi kapangidwe kake. Malinga ndi kapangidwe kake, imatha kugawidwa mumtengo umodzi wa cantilever, mzati wapawiri wa cantilever, mtengo wa chizindikiro cha cantilever ndi mzati wa chizindikiro cha cantilever.
Ndodo yowongoka kapena mkono wopingasa wothandizira umatenga chitoliro chachitsulo chowongoka kapena chitoliro chachitsulo chopanda msoko. Kumapeto kwa ndodo yowongoka ndi mkono wothandizira wopingasa amapangidwa ndi chitoliro chachitsulo chofanana ndi mkono wa mtanda, ndipo amatetezedwa ndi mbale yolimbitsa zitsulo. Mzati woyima ndi maziko amalumikizidwa ndi ma flanges ndi ma bolts ophatikizidwa, ndipo amatetezedwa ndi mbale zowotcherera; Kulumikizana pakati pa mkono wamtanda ndi kumapeto kwa mtengo wowongoka kumalumikizidwa ndikutetezedwa ndi mbale zowotcherera.
Ma welds onse a mtengo wowongoka ndi zigawo zake zazikulu zidzakwaniritsa zofunikira, ndipo pamwamba pake padzakhala yosalala komanso yosalala. Kuwotcherera kudzakhala kosalala, kosalala, kolimba komanso kodalirika, komanso kopanda zilema monga pores, kuwotcherera slag ndi kuwotcherera zabodza. Mzati ndi zigawo zake zazikulu zimakhala ndi ntchito yoteteza mphezi. Chitsulo chosagwiritsidwa ntchito cha nyalicho chimapanga chonse ndipo chimagwirizanitsidwa ndi waya wapansi kupyolera mu bolt pansi pa chipolopolo. Mzati ndi zigawo zake zazikulu zidzakhala ndi chipangizo chodalirika chokhazikika, ndipo kukana kwapansi kudzakhala ≤ 10 Ω.
Njira yochizira pamtengo wamagalimoto: chingwe chachitsulo chiyenera kudumpha mwamphamvu kuseri kwa mlongoti ndipo sichingamasulidwe. Panthawiyi, kumbukirani kusagwirizana ndi magetsi kapena kuzimitsa magetsi akuluakulu, ndiyeno kuyimitsa ntchitoyi. Malinga ndi kutalika kwa mtengo wowala, pezani crane yapamwamba yokhala ndi mbedza ziwiri, konzani dengu lopachikidwa (tcherani khutu ku mphamvu yachitetezo), ndiyeno konzani chingwe chachitsulo chosweka. Kumbukirani kuti chingwe chonsecho sichinathyoledwe, dutsani njira ziwiri kuchokera pansi pa dengu lopachikidwa, ndikudutsa mudengu la hanger. Yembekezani mbedza pa mbedza, ndipo samalani kuti mbedzayo iyenera kukhala ndi inshuwalansi ya chitetezo kuti isagwe. Konzani ma interphone awiri ndikukweza mawu. Chonde sungani ma frequency abwino oimba. Woyendetsa crane atalumikizana ndi oyang'anira magetsi, yambani ntchito. Chonde dziwani kuti ogwira ntchito yokonza nyali yayikulu ayenera kukhala ndi chidziwitso chamagetsi ndikumvetsetsa mfundo yokweza. Opaleshoni ya crane iyenera kukhala yoyenera.
Dengulo likakwera kufika pamtunda wodziwikiratu, woyendetsa malo okwera amagwiritsa ntchito chingwe cha waya kulumikiza mbedza ina ya crane ku mbale yowunikira. Akaikweza pang’ono, amagwirizira choikapo nyalecho ndi dzanja lake n’kulikwezera m’mwamba, pamene ena amagwiritsa ntchito sikelo kuti amasule. Chingwecho chikamatidwa, ikani chidacho kutali, ndipo crane imakweza dengu kumbali imodzi osakhudza kukweza kwabwinobwino. Panthawiyi, woyendetsa pansi anayamba kuyika mbale yowala mpaka inagwa pansi. Ndodo ya mtangayo inabweranso pamwamba pa mtengowo, n’kubweza mbedza zitatuzo pansi, kenako n’kuzipukuta. Gwiritsani ntchito chopukusira kuti muvale bwino ndi batala, kenaka yikaninso bawuti yolumikizira (malata), ndiyeno muyikhazikitsenso pamwamba pa ndodo, ndikutembenuza mbedzazo kangapo ndi dzanja mpaka zitatenthedwa bwino.
Zomwe zili pamwambazi ndizomwe zimapangidwira komanso mawonekedwe a chizindikiro cha magalimoto. Panthawi imodzimodziyo, ndinayambitsanso njira yopangira magetsi a chizindikiro. Ndikukhulupirira kuti mupezapo kanthu mukawerenga izi.
