Zikafika pa zomangira zomwe zimatha kunyamula katundu wolemetsa komanso zovuta, ma bolts olima amawonekera ngati chisankho chodalirika. Amadziwika chifukwa cha kulimba kwawo, mphamvu zawo komanso kukana kumeta ubweya wa mphamvu, amadziŵika ndi lathyathyathya kapena dome-monga, mutu wa countersunk ndi khosi lalikulu, zomwe zimalepheretsa bolt kutembenuka panthawi yoika. Khosi lalikulu limakhala mu dzenje lalikulu, nthawi zambiri pagawo lokwerera, kuteteza kasinthasintha pamene mtedza ukumitsidwa. Kapangidwe kameneka kamakhala kopindulitsa kwambiri pakugwiritsa ntchito komwe mbali imodzi ya olowa siyikupezeka, kuwapangitsa kukhala chisankho chodziwika bwino chophatikizira masamba ndi m'mphepete mwa makina olemera ndi zida.
Kodi mabawo a pulawo amagwiritsidwa ntchito kuti?
Maboti a pulawo amagwiritsidwa ntchito m'mapulogalamu osiyanasiyana omwe amafuna kulumikizana kolimba komanso kodalirika. Zina mwazogwiritsidwa ntchito kwambiri ndi izi:
Makina Azaulimi: Monga dzina likunenera, zolimira zimagwiritsidwa ntchito kwambiri paulimi. Amagwiritsidwa ntchito nthawi zambiri kumamatira mapulawo, zingwe zolima, ndi zida zina zamakina. Mabotiwa amatha kupirira zovuta zobwera chifukwa cha kulima ndi kulima nthaka, zomwe zimawapangitsa kukhala ofunikira kuti ntchito yaulimi isamayende bwino.
Zida Zomangira: M'makampani omanga, ma bolts amagwiritsidwa ntchito kuti ateteze m'mphepete ndikuvala zida zolemera monga ma bulldozer, ma grader, ndi ma loader. Kuthekera kwa zolimira kukana kumeta ubweya ndi kusunga kulumikizana kotetezeka ndikofunikira kuti makinawa azigwira ntchito komanso kukhala ndi moyo wautali.
Zida za Mgodi: Maboti olima amapeza ntchito m'makampani amigodi, pomwe zida zolemetsa zimakhala zovuta kwambiri. Amagwiritsidwa ntchito kumangiriza zida monga mano a ndowa, mafosholo, ndi zida zotumizira, kuwonetsetsa kuti migodi ikuyenda bwino komanso mosatekeseka.
Zida Zochotsa Chipale chofewa: Zolima chipale chofewa ndi zowuzirira chipale chofewa zimadalira zomangira kuti zikhomere m'mphepete ndi masamba. Kulimba kwa mabawutiwa kumatsimikizira kuti zidazo zitha kuchotsa chipale chofewa bwino m'misewu, malo oimikapo magalimoto, ma driveways, ndi misewu.
Makina Odula Mitengo: M’makampani odula mitengo, zolimira zimagwiritsidwa ntchito kutchingira zinthu monga macheka ndi m’mphepete mwa makina monga macheni ndi zogawaniza mitengo. Mphamvu ndi kukhazikika koperekedwa ndi ma pulawo a pulawo kumathandiza kuti ntchito yodula mitengo ikhale yotetezeka.
Kukonza Sitima: Maboti olima amagwiritsidwanso ntchito pokonza njanji kuti amangirire zinthu monga masiwichi a njanji ndi matayi. Kudalirika kwawo ndikofunikira pakuwonetsetsa chitetezo ndi magwiridwe antchito anjanji.
Momwe Maboti Olimira Amagwirira Ntchito
Mapangidwe a pulawo amathandizira kuti azigwira ntchito komanso kudalirika. Umu ndi momwe ma bolt a pulawo amagwirira ntchito:
1. Kukonzekera Bowo: Bowo la square limapangidwa mu gawo lokweretsa, lomwe limagwirizana ndi khosi lalikulu la bolt. Izi zimalepheretsa bawuti kuti isazungulire pakuyika.
2. Kulowetsa: pulawo amalowetsedwa mu dzenje lalikulu, ndi mutu wathyathyathya, wosunthika wowunikiridwa pamwamba pa gawolo.
3. Kumanga: Kumbali ina ya msonkhano, wochapira ndi mtedza zimakokedwa pa tsinde la ulusi wa pulawo. Pamene mtedzawo umangirizidwa, khosi lalikulu limalepheretsa bolt kuti lisagwedezeke, kupanga mgwirizano wotetezeka komanso wokhazikika.
4. Kulimbitsa Torque: Maboliti a pulawo amayenera kumangidwa pa torque inayake kuti atsimikizire mphamvu yokhomerera yoyenera. Kulimbitsa mopitirira muyeso kungayambitse kupsinjika kwakukulu pa chomangira, pamene kutsika kungayambitse kusagwirizana.
Kodi mumayesa bwanji kutalika kwa boliti?
Maboti a pulawo amatha kukhala ndi mutu wathyathyathya kapena mutu wa dome. Ngakhale kuti kukula kwake kumayesedwa mofanana ndi bawuti iliyonse, kutalika kwa bawuti iliyonse kumayesedwa mosiyana.
Kwa ma bawuti a pulawo akumutu athyathyathya, kutalika kwake kumayesedwa kuchokera pamwamba pa mutu mpaka kumapeto kwenikweni kwa mabawuti opangidwa ndi ulusi.
Kwa mabawuti a pulawo ya mutu wa dome, utali wake umayezedwa kuchokera pagawo lalikulu kwambiri la mutu mpaka kumapeto kwenikweni kwa bawuti yolumikizidwa. Gawo la dome la mutu (lomwe likutuluka pamene bolt likugwiritsidwa ntchito) silikuphatikizidwa muutali.
