Lublub tshuab gantry craneyog ib yam khoom siv tseem ceeb uas siv rau hauv kev tsim choj los sib sau ua ke thiab teeb tsa cov girders choj. Nws yog ib lub tshuab tshwj xeeb uas tsim los tsa, thauj thiab tso cov girders choj hnyav rau hauv qhov chaw, ua rau nws yog ib feem tseem ceeb ntawm kev tsim choj.
Lub girder hoist muaj ntau yam tseem ceeb uas ua haujlwm ua ke los xyuas kom meej tias kev teeb tsa choj girders muaj kev nyab xeeb thiab ua haujlwm tau zoo. Ib qho ntawm cov khoom tseem ceeb yog lub ntsiab beam, uas yog lub ntsiab lus tseem ceeb ntawm lub launcher. Lub ntsiab beam yog lub luag haujlwm los txhawb qhov hnyav ntawm lub choj lub ntsiab beam thiab muab kev ruaj khov thaum lub sijhawm tsa thiab tso tawm.
Lwm yam tseem ceeb ntawm lub tshuab tua hluav taws xob tseem ceeb yog lub taub hau tua hluav taws xob, uas nyob rau ntawm pem hauv ntej ntawm lub taub hau tseem ceeb. Lub taub hau xa hluav taws xob muaj cov khoom siv tshwj xeeb xws li cov hydraulic jacks thiab cov khoom siv nqa kom raug thiab tso qhov chaw ntawm cov choj girders. Nws kuj tseem muaj lub truss tua hluav taws xob uas muab kev txhawb nqa ntxiv thiab kev ruaj khov thaum lub sijhawm tua hluav taws xob.
Lub kaw lus counterweight yog lwm qhov tseem ceeb ntawm lub beam launcher thiab nws tau tsim los kom sib npaug qhov hnyav ntawm tus choj thiab lub launcher nws tus kheej. Lub kaw lus no ua kom lub launcher tseem ruaj khov thiab muaj kev nyab xeeb thaum tsa thiab tso cov girders, txo qhov kev pheej hmoo ntawm kev sib tsoo lossis kev puas tsuaj ntawm cov qauv.
Tsis tas li ntawd xwb, lub tshuab tua nqaj hlau muaj lub kaw lus tswj hwm siab heev uas tso cai rau tus neeg teb xov tooj saib xyuas thiab kho cov txheej txheem tsa thiab tso tawm. Lub kaw lus tswj hwm suav nrog cov khoom siv hydraulic thiab hluav taws xob uas ua rau muaj kev txav mus los meej thiab tswj tau kom ntseeg tau tias muaj kev nyab xeeb thiab raug ntawm cov girders choj.
Hauv kev xaus lus, lub girder hoist yog ib qho khoom siv tsim kho choj uas muaj ntau yam khoom tseem ceeb uas ua haujlwm ua ke los tsa, thauj thiab tso cov girders choj thaum lub sijhawm tsim kho choj. Nws txoj kev tsim qauv tshiab thiab thev naus laus zis siab heev ua rau nws yog ib qho cuab yeej tseem ceeb rau cov haujlwm tsim kho choj, ua rau kev teeb tsa cov girders choj tau zoo thiab muaj kev nyab xeeb.
