Jib crane feem ntau yog siv los ua kev pabcuam hauv kev ua haujlwm ntawm cov nyiaj siv ua haujlwm crane thiab tau nruab rau hauv tib chav, tab sis ib qib qis dua. Hom no nrov heev hauv kev lag luam. Qhov no tau piav qhia los ntawm nws ntau yam, yooj yim thiab efficiency.
Hauv kev lag luam, feem ntau muaj ob hom jib cranes - mobile thiab jib crane. Txawb yog lub console mounted ntawm ib txoj kab ntsug. Lub thav duab, nyob rau hauv lem, rests ntawm ob lub log nrog ib tug nyias tsav. Xws li ib tug crane yog tsau rau ntawm phab ntsa, nws tsuas yog txav raws nws. Kev txav mus los yuav tshwm sim nrog cov lus qhia tshwj xeeb uas siv lub tshuab hluav taws xob.
Hom thib ob yog qhov chaw nres tsheb cantilever crane. Hom no yog txuas nrog rau ntawm phab ntsa ntawm lub tsev los yog mus rau ib qho vertically sawv tubular los yog lub thawv-zoo li kem. Nyob rau hauv rooj plaub no, kem yog muab tso rau ntawm lub hauv paus. Thaum lub console tuaj yeem tig, hom no hu ua "cantilever-slewing crane".
Kev txav ntawm cov khoom yog ua nrog kev pab ntawm lub hoist tsau ntawm lub console thiabtxav raws nws. Nws tuaj yeem txav tau ob qho tib si nrog kev pab ntawm lub tshuab nruab rau ntawm nws tus kheej, thiab nrog kev pab los ntawm ib lub cable traction ua rau lub console winch. Nyob rau hauv rooj plaub thib ob, nws muaj peev xwm txav tau cov loads nrog ntau yam ceev. Lub console nws tus kheej yog tsiv manually, nrog kev pab los ntawm ib tug hlua, feem ntau tsau nyob rau hauv nws kawg, los yog ib tug hluav taws xob lub cev muaj zog. Hauv qhov kawg, cov cuab yeej yuav raug hu ua "cantilever electric crane".
Yog tias ib kem siv los ua kev txhawb nqa, lub crane tuaj yeem muaj ob txhais caj npab. Nws yog hu ua ob lub xub pwg nyom. Ib sab caj npab (ib leeg-girder) cranes yog sib dua thiab tsis tshua kim. Ob txhais caj npab tuaj yeem nqa qhov hnyav dua thiab tuaj yeem tiv taus qhov hnyav dua.
Kev siv tau ntau hom cranes
- Yog tias nws tsim nyog los nqa cov khoom uas tsis hnyav dhau, nws yog qhov zoo dua los siv lub jib crane nrog phau ntawv hoist thiab phau ntawv sib hloov ntawm lub console. Cov khoom siv no feem ntau yooj yim heev, vim lawv yooj yim rau kev khiav lag luam.
- Yog tias koj xav tau nqa thiab txav cov khoom hnyav, nws yog qhov zoo dua los siv lub crane nrog hluav taws xob traction. Tsis tas li ntawd, nws tsis yog qhov phem yog tias nws tau nruab nrog lub hoist (lub tshuab fais fab rau txav lub hoist).
- Yog tias yuav tsum muaj kev ruaj ntseg tshwj xeeb rau ib qho laj thawj tsim khoom, nws yog qhov zoo tshaj plaws kom txav cov khoom siv ob sab caj npab cantilever crane.
Ntxiv rau, kev lag luam tsim cov cuab yeej no thiab xaj, yog tias tsim nyog, nws ua haujlwm hauv ib qho twgtej yam kev mob. Nyob rau tib lub sijhawm, qhov ntev ntawm lub console, nws lub kaum sab xis ntawm kev sib hloov, qhov siab ntawm lub load, tag nrho lub peev xwm ntawm lub crane tuaj yeem nce ntxiv.
Jib crane feem ntau siv rau kev pabcuam warehouses, chaw tsim khoom, chaw tsim khoom me me, cov ntawv tshwj xeeb, thiab lwm yam. Raws li ntau xyoo dhau los ntawm kev siv cov txheej txheem no, nws tuaj yeem hais nrog kev ntseeg siab tias nws tuaj yeem yog qhov tseem ceeb hauv ntau qhov kev lag luam - mechanical engineering, loading and unloading terminals, machine shop, etc.
