FAQ:
Vim li cas thiaj xaiv H-section truss hla lub tubular truss rau lub crane- pabcuam lub tsev?
Ib qho khoom H chord nqa ntsug crane thiab hauv zos hnyav hnyav dua li lub raj nyias - txog 30% siab dua lub sijhawm ntawm inertia ntawm tib qhov hnyav. Yog li rau cov nroj tsuag nrog 50-tuj cranes thiab cov tshuab ua haujlwm siab, H-section truss muab kev ua haujlwm ruaj khov, nyab xeeb dua; tubular qhov chaw truss haum lub teeb yuag nkhaus ntev-ntev architecture hloov.
Lub crane loj npaum li cas los yog nqa cov teeb tsa kuv yuav tsum tau txhim kho cov trusses?
Nws nyob ntawm ntu ntev thiab qhov hnyav. Peb loj shippable ntu yog li lub mobile crane ntawm chav kawm koj paub meej nrog peb txoj kev npaj erection tuaj yeem xaiv lawv; peb muab cov ntsiab lus lifting thiab ib ntu yuag daim ntawv teev npe kom koj tuaj yeem ntiav lub tshuab zoo yam tsis muaj kev kwv yees.
Lub ru tsev txoj kab nqes ua haujlwm li cas nrog kev tsim truss?
Sab saum toj -chord theem thiab kawg- cov kabmob phaj yog teem rau koj lub ru tsev txoj kab nqes, yog li cov kua dej thiab vaj huam sib luag profiles (xws li sawv-seam) khi kom huv si rau lub truss. Peb ua qauv ntawm txoj kab nqes tiag tiag rau hauv Tekla chord geometry es tsis yog xav tias tus tswvcuab tiaj tus.
Dab tsi yog ua ntej -camber rau, thiab vim li cas thiaj xav tau nws?
Manufactured pre-camber offsets downward deflection ib loaded truss tsim, yog li nyob rau hauv tag nrho load lub chord theem tawm mus rau tus tsim kab. Yog tsis muaj nws, ib tug ntev ncua sags pom nyob rau nruab nrab -span; peb teeb tsa thiab tuav ua ntej-camber los ntawm kev sib txuas thiab kev soj ntsuam ib ntus.
Kuv yuav siv nyiaj li cas rau cov hlau tonnage rau ib qhov project?
Raws li daim ntawv qhia kev npaj, H-section truss framing feem ntau tsaws hauv qhov sib piv ntawm ib square meter mus rau qhov zoo sib xws welded ua-up system ib zaug ncua sij hawm thiab crane load tau tsau; xa span, bay spacing, gradient thiab crane muaj peev xwm thiab peb paub meej seem + kwv yees tons hauv 24 teev.
