Sany 80-ton Crane STC800T6: Chida Chaumisiri Chothandiza komanso Chodalirika 

Sitima yapamtunda ya STC800T6 80-tons yomwe idakhazikitsidwa ndi Sany Heavy Viwanda yakhala chida chokondedwa kwambiri pantchito yomanga ndi zomangamanga chifukwa cha magwiridwe ake apamwamba, kapangidwe kanzeru komanso kukhazikika kodalirika, zopindulitsa zake zazikulu zimakhazikika pamagawo angapo.

Pankhani yokweza magwiridwe antchito, STC800T6 imapambana. Imatengera kapangidwe kake kagawo kakang'ono ka magawo asanu ndi limodzi, kokhala ndi kutalika kopitilira muyeso mpaka 55 metres komanso kukulitsa kwakukulu kwa jib mpaka 27 metres. Kutalika kophatikizana kwa boom kumatha kukwaniritsa zosowa za zochitika zovuta monga kukweza nyumba zapamwamba komanso kumanga mlatho. Kukweza kwake kwakukulu kumafika matani 80, ndipo mphamvu yokweza pamtunda wa 3-mita ndi 800kN, yomwe ili yoposa zida zina za msinkhu womwewo. Kuphatikiza apo, boom imapangidwa ndi chitsulo champhamvu kwambiri cha Q690, chomwe chimachepetsa kulemera kwinaku chikukweza mphamvu yonyamula katundu, kuwonetsetsa kuti chitetezo chimagwira ntchito ndikuchepetsa kugwiritsa ntchito mphamvu.

Kuchita bwino kwambiri komanso kupulumutsa mphamvu kwamagetsi ndi chinthu china chofunikira kwambiri. Kireniyi ili ndi injini ya Weichai WP12.460 yomwe imagwirizana ndi National VI emission standard, yomwe ili ndi mphamvu zokwana 338kW, zomwe zimakhala zamphamvu komanso zopanda mafuta. Imafanana ndi gearbox ya Fast 10-speed gearbox, yomwe imayenda bwino ndikusintha misewu yovuta monga misewu yamapiri ndi malo omanga. Kuphatikiza apo, makina ake opangira ma hydraulic amatenga ukadaulo wowongolera katundu, womwe ungathe kusintha molondola kayendedwe kake malinga ndi zofunikira zogwirira ntchito, kupewa kuwononga mphamvu. Ndi pafupifupi 15% yowonjezera mphamvu kuposa zipangizo zamakono, kuchepetsa ndalama zogwiritsira ntchito nthawi yaitali.

Luntha komanso kuphweka kwa magwiridwe antchito kumathandizira kwambiri magwiridwe antchito. Dongosolo lowongolera mwanzeru lomwe lili ndi chophimba cha 10.1-inchi chokhudza kukhudza kumatha kuwonetsa magawo ofunikira monga kukweza kulemera, ma radius ndi kutalika kwa boom munthawi yeniyeni, kuthandizira kudzizindikiritsa nokha ndikuwunika kwakutali kuti muthe kuthana ndi mavuto munthawi yake. Ntchito monga kuyimitsidwa kwa kiyi imodzi, kusanja kwadzidzidzi ndi kuchepa kwa torque kumachepetsa zovuta zogwirira ntchito, kulola kuti ngakhale novices ayambe msanga komanso kuchepetsa kwambiri nthawi yokonzekera ntchito. Nthawi yomweyo, kabatiyo imatenga mawonekedwe oyimitsidwa, okhala ndi zowongolera mpweya komanso mipando yowopsa, yomwe imathandizira kuti ogwira ntchito azikhala otonthoza komanso amachepetsa kutopa kwa nthawi yayitali.

Njira yotsimikizira chitetezo ndi yathunthu komanso yodalirika. Zidazi zili ndi zida zambiri zotetezera chitetezo, kuphatikizapo torque limiter, kutalika kwa malire, kulemera kwake, ndi zina zotero, zomwe zimachenjeza ndikudula zinthu zoopsa pamene ntchitoyo ili pafupi ndi malire a chitetezo. Chojambulacho chimatenga mawonekedwe amtundu wa bokosi ndi machitidwe amphamvu a torsional, ndipo kutuluka kwa kunja kumakhala kwakukulu ndipo chithandizocho chimakhala chokhazikika, chomwe chingathe kukhala bwino ngakhale m'malo opapatiza, kuchepetsa kuchepetsa chiopsezo cha kugwedezeka.

Kuonjezera apo, maukonde abwino a Sany pambuyo pa malonda amapereka chithandizo chokonzekera ndi kukonzanso panthawi yake, ndi zowonjezera zowonjezera zowonjezera, zomwe zimachepetsa kwambiri kuwonongeka kwa zipangizo komanso kupititsa patsogolo luso la wogwiritsa ntchito.
