Lifting ntauwd nyob rau hauv tus txheej txheem ntawm kev siv txoj hlua khi ntawm sab laug thiab sab xis kom ruaj khov, slewing mus rau qhov siab xav tau, yuav tsum tau maj mam nqis mus rau qhov chaw ruaj khov, kom tsis txhob muaj xwm txheej thiab hnav thiab tsim kua muag sai heev.Ntawm txoj kev ntawm kev teeb tsa, yog tias pom muaj teeb meem ua ntej kev ntsuas kub ceev, tom qab ua tiav thiab tom qab ntawd nqa kev ua haujlwm.
1. Lub peev xwm nqa crane yog tsau, qhov loj dua lub voj voog ua haujlwm ntawm crane.Qhov sib zog ntawm cov khoom nqa, qhov me me ntawm lub voj voog ua haujlwm, qhov hnyav dua cov khoom nqa.Lub vojvoog ua haujlwm yog kab rov tav nrug ntawm lub sijhawm nruab nrab mus rau qhov sib txuas.
2. Nkag siab qhov loj ntawm cov khoom nqa nqa, nrhiav qhov nruab nrab ntawm cov khoom mus rau qhov chaw ntawm lub crane kem nrug, raws li qhov kev ncua deb saib cov crane lifting peev tsis.
3. Xav txog qhov nqa qhov hnyav ntawm lub crane thiab chassis loj muaj peev xwm, beam yog xaiv qhov loj dua qhov zoo, lub crane loj thiab chassis me me, yuav ua rau cov nqaj deformation thiab puas.Chassis yog me me, lub cav fais fab yog me me, cuam tshuam lub peev xwm nqa ntawm crane.Yog li thaum peb xav txog 230mm beam, peb xaiv lub crane hauv qab 3 tons.Thaum peb xav txog 250 hli nqaj, peb xav txog crane hauv qab 6 tons.280mm nqaj tuaj yeem xaiv crane hauv qab 8 tons.Chassis zoo li rear yim lub log thiab pem hauv ntej plaub tuaj yeem xav txog crane hauv qab 10 tons.
