Chimodzi mwazinthu zabwino zoyambiracranes pansi pa mlathondi mapangidwe awo apadera, omwe amawalola kuti ayimitsidwe panyumba yomwe ilipo. Kukonzekera uku kumathetsa kufunikira kwa mizati yowonjezera yothandizira, kupereka malo ogwirira ntchito momveka bwino pansipa. Chifukwa chake, izi zimapangitsa kuti pakhale mawonekedwe otseguka komanso osinthika, zomwe zimapangitsa kuti makina ndi zida zikhale zosavuta.
Nawa maubwino ena ogwiritsira ntchito ma cranes a underhung bridge kuti athetse njira zokweza bwino:
Kuchuluka kwa Mphamvu:Ma cranes apansi pa mlathoamatha kunyamula katundu wambiri, kuchokera ku kuwala kupita ku zipangizo zolemera. Kusinthasintha kumeneku kumawapangitsa kukhala oyenera kugwiritsa ntchito zosiyanasiyana, monga kupanga, malo opangira zinthu, ndi malo ogawa.
Chitetezo Chotukuka: Kapangidwe kameneka kamachepetsa ngozi ndi kuvulala pochepetsa kupondaponda kwa crane. Kuyika kwapamwamba kumatanthauzanso kuti ogwira ntchito sangakumane ndi zida za crane, zomwe zimachepetsanso mwayi wa ngozi.
Kuchita Zowonjezereka:Ma cranes apansi pa mlathoadapangidwa kuti aziyenda bwino komanso moyenera, zomwe zimapangitsa kuti azinyamula mwachangu komanso moyenera. Izi zimabweretsa kuchepa kwa nthawi yozungulira komanso kuchulukirachulukira, zomwe zimapangitsa kuti ntchito zonse ziziyenda bwino.
Kuchepetsa Kukonza: Mapangidwe a underhung amathandizanso kuti pakhale zofunikira zosamalira. Pokhala ndi zigawo zocheperako komanso kuchepetsedwa kwa magawo osuntha, ma cranewa samakonda kuvala ndi kung'ambika, zomwe zimapangitsa moyo wautali wautumiki ndikuchepetsa nthawi.
Kusintha mwamakonda:Single girder underslung cranesikhoza kusinthidwa kuti ikwaniritse zosowa zenizeni za malo. Izi zikuphatikizapo zosankha zamapangidwe amodzi kapena awiri, zonyamula zosiyanasiyana, ndi machitidwe osiyanasiyana owongolera.
Mphamvu Zamagetsi: Makanema amakono a single girder underslung adapangidwa ndi zida zopangira mphamvu, monga ma frequency frequency drives ndi regenerative braking systems. Zinthuzi sizimangochepetsa kugwiritsa ntchito mphamvu komanso zimathandizira kuti pakhale mpweya wocheperako.
Pomaliza,cranes pansi pa mlathoperekani njira yabwino komanso yotsika mtengo yogwiritsira ntchito zinthu m'mafakitale osiyanasiyana. Popereka mphamvu zowonjezera, chitetezo chokhazikika, zokolola zambiri, komanso kukonza pang'ono, ma cranes awa amathandiza mabizinesi kukhathamiritsa ntchito zawo ndikukhalabe opikisana pamsika wamasiku ano ovuta.
