Kireni ya Mlatho wa Underhanged Double Girder

Ma cranes a mlatho wa Underhung double girder amapereka yankho lolimba kwambiri pa ntchito zokhala ndi katundu wolemera, liwiro lalikulu, komanso kutalika kwa nthawi yayitali. Ma cranes a mlatho wa Underhung double girder amaperekanso njira yabwino kwambiri yolowera m'mbali ndipo amagwiritsa ntchito bwino m'lifupi ndi kutalika kwa nyumbayo akathandizidwa ndi denga kapena denga.

Ma cranes a mlatho wa girder awiri opangidwa ndi kampani yathu ali ndi mphamvu zonyamula katundu wokwana matani 500 ndi kutalika koyenera mpaka mamita 40, komwe kumatha kunyamula katundu wolemera mosamala komanso molondola. Akhoza kusinthidwa kuti agwirizane ndi nyumba zomwe zakonzedwa kapena zomwe zilipo kale kudzera mu njira zosiyanasiyana zapadera zoyikira. Ma cranes a girder awiri pamwamba amatha kuyendetsedwa kuchokera pansi pogwiritsa ntchito chingwe cholumikizira cholumikizidwa kapena ndi wailesi yowongolera kutali. Kuphatikiza apo, zowongolera zingapo zimatha kuchitika posintha zowongolera kuchokera ku mtundu wina kupita ku wina, kulola kuti crane igwire ntchito m'njira zamanja, zodziyimira zokha kapena zodziyimira zokha. Sevencrane ikhoza kukupatsani crane ya mlatho wa girder awiri yapamwamba komanso yogwira ntchito bwino, chonde titumizireni momasuka kuti mudziwe zambiri zanu mwachangu momwe mungathere.

Kuyang'anira ndi kuyesa ma crane oyenda pamwamba. (1) Kawirikawiri, ma crane a mlatho ayenera kufufuzidwa kamodzi pachaka. (2) Ngati kukhazikitsa kwatsopano, kukonzanso, kusintha, kugwiritsa ntchito nthawi yanthawi yayitali mpaka zaka ziwiri kapena kusagwiritsidwa ntchito kwa nthawi yoposa chaka chimodzi ya crane ya mlatho, kuyenera kutsatira njira zoyesera makina okweza mayeso ake. Ayenera kugwiritsidwa ntchito asanayambe kugwiritsidwa ntchito. (3) mayeso a katundu kuphatikizapo mayeso osanyamula katundu, mayeso okhazikika a katundu, mayeso othamanga a katundu.

Malangizo Oteteza Kuyang'anira. (1) Antchito apadera ayenera kupatsidwa udindo woyang'anira kuwunikako. Maphunziro a chitetezo ayenera kuperekedwa kwa ogwira ntchito oyenerera asanagwire ntchito kuti amvetsetse zofunikira za malamulo oyenera. Nthawi yomweyo, kugawa kwa ogwira ntchito kuyenera kukhala komveka bwino. (2) Yang'anani crane ya pamwamba motsatira malamulo a chitetezo cha ntchito zamakanika, zamagetsi ndi zamlengalenga. (3) Panthawi yoyesa, ogwira ntchito oyenerera ayenera kuyima pamalo otetezeka. (4) Njira zotetezera poyankha mwadzidzidzi pazochitika zadzidzidzi komanso zoopsa ziyenera kupangidwa.
