Lub log crane yog ib qho tseem ceeb ntawm cov crane. Nws yog nyob rau hauv kev sib cuag nrog tus khiav thiab plays lub luag hauj lwm ntawm kev txhawb nqa lub crane load thiab khiav kis tau tus mob. Qhov zoo ntawm lub log muaj feem xyuam rau qhov ntev ntawm lub crane lub neej ua haujlwm.
Raws li cov txheej txheem ntau lawm, crane log tuaj yeem muab faib ua forged log thiab cam khwb cia log. Peb lub tuam txhab muaj ntau xyoo ntawm crane log forging kev, thiab tau muab cov khoom zoo rau ntau lub lag luam hnyav.
Cov ntaub ntawv tseem ceeb ntawm crane log puas yog hnav, hardened txheej crushing thiab pitting. Txhawm rau txhim kho qhov hnav tsis kam thiab lub neej ntawm lub log nto, cov khoom siv ntawm lub log feem ntau yog 42CrMo alloy steel, thiab lub log tsheb yuav tsum raug kho kom sov saum npoo thaum ua cov txheej txheem los txhim kho qhov hnav tsis kam. Lub hardness ntawm lub log tom qab ua tiav yuav tsum yog HB300-350, qhov tob tob tshaj 20 hli, thiab cov log uas tsis ua raws li qhov yuav tsum tau ua kom rov ua kom sov.
Lub log crane yuav tsum tau mus txog qhov kawg hardness kuaj ua ntej tawm hauv lub hoobkas. SEVENCRANE nruj me ntsis raws li cov cai ntawm kev soj ntsuam cov cai los xaiv qhov hardness ntawm tread nto thiab sab hauv ntawm lub npoo ntawm lub crane log.
Siv lub hardness tester los ntsuas peb lub ntsiab lus sib npaug ntawm qhov ncig ntawm lub tread ntawm lub log, thiab ob ntawm lawv tsim nyog. Thaum tus nqi hardness ntawm qhov ntsuas qhov ntsuas tsis ua tau raws li qhov yuav tsum tau ua, ob lub ntsiab lus ntxiv nrog rau qhov kev taw qhia axis ntawm qhov taw tes. Yog tias ob lub ntsiab lus tsim nyog, nws tsim nyog.
Thaum kawg, lub log crane tuaj yeem muab tso rau hauv kev siv tsuas yog tom qab daim ntawv pov thawj zoo thiab cov ntaub ntawv pov thawj raug muab rau lub log uas tau dhau qhov kev tshuaj xyuas. Muaj peev xwm siv cov khoom siv hlau tsim nyog thiab raug tsim thiab ua cov cuab yeej siv tshuab thiab kev kho cua sov yog ib qho tseem ceeb los xyuas kom meej qhov zoo ntawm cov crane taug kev log.
