Qhov siab tshaj plaws boom lub kaum sab xis rau crawler cranes yog qhov tseem ceeb cuam tshuam rau lawv lub peev xwm nqa thiab kev nyab xeeb ntawm kev ua haujlwm, tshwj xeeb tshaj yog rau cov booms ntev. Kev nkag siab txog lub kaum sab xis ntawm lub crane boom ua kom muaj kev ruaj ntseg ntawm cov khoom siv thiab tiv thaiv cov xwm txheej zoo. Tsis tas li ntawd, kev paub txog ntau hom crane booms tuaj yeem txhim kho kev ua haujlwm zoo thiab kev nyab xeeb.
Lattice boom crane
Lattice boom cranes tuaj yeem siv dav hauv lifting teb xws li cua fais fab kev tsim kho, choj kev tsim kho, petrochemicals, thiab municipal engineering. Lawv cov qauv tsim tshwj xeeb siv cov kab hlau sib txuas sib txuas los tsim cov qauv truss uas tso cai rau lub boom mus txuas ntxiv thiab thim rov qab. Qhov kev tsim no tsis tsuas yog muab lub zog zoo tshaj uas yuav tsum tau nqa cov khoom hnyav, tab sis kuj tseem ua kom tag nrho qhov hnyav ntawm crane kuj qis. Tsis tas li ntawd, nws yog ib qho tseem ceeb rau kev booms ntev ntawm crawler cranes, cov qauv truss no txhim khu kev ruaj ntseg thiab kev ua haujlwm zoo hauv ntau daim ntawv thov nqa.
Feem ntau, qhov siab tshaj plaws ua haujlwm ntawm lub lattice boom crane yog 70 degree txog 80 degree. Lub kaum sab xis no yog qhov tseem ceeb vim tias nws ua kom ruaj khov nqa lub peev xwm txawm tias nyob rau qhov siab dua, yog li txhim kho kev ua haujlwm ruaj ntseg. Cov cranes no tshwj xeeb tshaj yog tsim rau cov ntawv nqa hnyav uas muaj peev xwm thauj khoom thiab ruaj khov yog qhov tseem ceeb, xws li thaum tsim cov qauv loj lossis tuav cov khoom loj.
Telescopic boom crane
Telescopic boom cranes yog ntau hom crane dav siv hauv chaw tsim kho, chaw nres nkoj, chaw nres tsheb, thiab lwm yam. Lawv muab cov txiaj ntsig zoo xws li kev yoog raws, kev ua tau zoo, thiab kev txuag chaw. Paub txog lawv txoj kev ua haujlwm sai, cov cranes no yog qhov zoo tagnrho rau cov chaw tsim kho uas yuav tsum tau hloov kho sai los tiv thaiv qhov tsis tau pom dua. Raws li ib qho ntawm cov hom tseem ceeb ntawm crane booms, telescopic boom cranes txhim khu kev ua haujlwm zoo thiab yoog raws, ua rau lawv tseem ceeb rau ntau yam haujlwm nqa hauv qhov chaw muaj zog.
Lub hauv paus ntsiab lus ntawm telescopic boom crane yog tsav qhov txuas ntxiv thiab thim rov qab ntawm lub boom los ntawm hydraulic system kom ua tiav qhov kev hloov ntawm qhov siab thiab qhov ntev. Lub hydraulic system muaj xws li cov roj tank, hydraulic twj tso kua mis, hydraulic solenoid valve, hydraulic lub tog raj kheej, roj kav dej thiab hydraulic maub los. Thaum tus neeg teb xov tooj ua haujlwm ntawm tus maub los, lub twj tso kua mis hydraulic pib, nias hydraulic roj rau hauv lub tog raj kheej hydraulic, thawb lub boom kom txav mus. Telescopic booms yog ua los ntawm cov khoom siv ruaj khov xws li txhuas lossis hlau alloys siab, tsim los tiv taus qhov hnyav hnyav thaum tswj kev ua haujlwm zoo. Lub kaum sab xis ua haujlwm ntawm cov cranes feem ntau yog nyob nruab nrab ntawm 70 degree thiab 85 degree, uas tuaj yeem muab kev pom kev ruaj ntseg thiab ruaj khov thaum ua haujlwm.
