Ob leeg koom nrog MG-series ob-girder gantry cranes, tsim los rau kev siv cov khoom siv sab nraum zoov hnyav, tab sis lawv lub ntsiab-girder structural tsim tsim qhov sib txawv loj hauv kev nruj, cua-load kev ua haujlwm, kev saib xyuas haujlwm thiab tag nrho cov nqi ntawm cov tswv cuab.

Ntau tus neeg yuav khoom tsuas yog sib piv tus nqi pib yuav khoom thaum tsis quav ntsej ISO chav haujlwm ua haujlwm, lub log-load ntawm lub hauv paus, txwv kev txwv thiab kev soj ntsuam mus sij hawm ntev. Kev xaiv tsis ncaj ncees lawm yuav ua rau muaj kev vibration ntau dhau, kev saib xyuas tsis tu ncua lossis ua haujlwm tsis zoo. Phau ntawv qhia no sib pivLub thawv girder vs truss ob chav girder gantry cranelos ntawm kev ua haujlwm hauv ntiaj teb tiag tiag, pab koj ua cov ntaub ntawv-tsav RFQ kev npaj thiab kev txiav txim siab xaiv cov khoom siv rau koj qhov project.

Dab tsi yog Box-Type Ob Chav Girder Gantry Crane

Lub thawv hom ob chav girder gantry crane txais yuav kaw lub thawv-section lub ntsiab girders fabricated los ntawm tuab steel-phaj tsis siv neeg vuam. Lub thawv kaw lub thawv-cov qauv muab qhov zoo tshaj plaws bending txhav thiab torsional tsis kam, uas yog lub ntsiab lus hnyav-lub luag haujlwm rau kev ua haujlwm siab-nruab nrab nqa.

Cov neeg tsim khoom lag luam ua qhov kev ntsuam xyuas tsis muaj kev puas tsuaj (NDT) rau kev nkag mus rau tag nrho cov welds, txhawb nqa los ntawm finite-element-analysis (FEA) suav ua ntej tsim khoom. Lub crane no txhawb nqa cov chav kawm ua haujlwm siab ISO xws li A4 txog A7, suav nrog nqa lub peev xwm ntawm 20 tons mus rau ntau dua 200 tons, thiab tso cai rau kev tsim qauv ntev ntev. Nws cov txheej txheej du ua kom yooj yim blasting thiab tiv thaiv corrosion ua hauj lwm rau ntug hiav txwv dej los yog corrosive ua hauj lwm ib puag ncig.

Cov teeb meem tshwm sim los ntawm nws cov khoom siv hlau-phaj: siab dua qhov hnyav ntawm tus kheej tuag nce lub log thauj mus rau cov kev sib tw khiav thiab cov pob zeb ua vaj tse, xav kom muaj zog dua kev lag luam hauv kev lag luam. Cov cua daj cua dub loj dua txhais tau hais tias cua daj cua dub ntau dua lub sijhawm thaum muab tso rau hauv qhov chaw siab cua qhib cua.

Dab tsi yog Truss Ob Chav Girder Gantry Crane

Lub truss ob chav girder gantry crane, tseem hu ua lattice-type ob-girder gantry crane, tsim lub ntsiab girders nrog lub kaum sab xis steel, channel steel lossis tubular profiles txuas ntawm gusset-phaj vuam. Raws li peb txoj kev quab yuam-hloov cov hauv paus ntsiab lus, qhov qhib-web lattice qauv zoo heev txiav steel noj thiab nws tus kheej-yuag piv nrog lub thawv-hom girders nyob rau hauv sib npaug span specifications.

Lub teeb tuag-qhov hnyav txo lub log load ntawm kev khiav thiab lub hauv paus, ua rau truss-style tsim kev lag luam sib tw rau ultra-ntev-span tej yaam num saum 40 m. Open-web layout cia cua ntws los ntawm lub girder, xa cov cua tiv thaiv kev ua tau zoo rau cov cua daj cua dub los yog qhov chaw siab. Truss ob-girder gantry cranes feem ntau raug ntsuas rau ISO A3-A5 cov chav kawm ua haujlwm, haum rau nruab nrab-load thiab sib cuam tshuam-lub voj voog nqa cov haujlwm.

Cov ntsiab lus tsis muaj zog loj yog los ntawm cov pob qij txha loj heev thiab cov kab sib txuas. Cov ntsiab lus tshuaj xyuas ntau dua yog xav tau rau kev tiv thaiv kev saib xyuas; plua plav, noo noo thiab xeb yooj yim khaws cia hauv qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob Nyob rau hauv qhov hnyav offset loads, loj dua deflection thiab cov qauv kev co yuav tshwm sim piv nrog lub thawv-hom counterparts.
