Precise positioning: Cov cranes no tau nruab nrog cov txheej txheem siab tshaj plaws uas ua kom muaj kev txav mus los thiab tso cov khoom hnyav. Qhov no yog qhov tseem ceeb rau qhov tseeb ntawm qhov chaw choj kab teeb, girders, thiab lwm yam khoom siv thaum lub sij hawm tsim kho.
Mobility: Choj siv gantry cranes feem ntau yog tsim los ua txawb. Lawv raug ntsia rau ntawm lub log lossis lem, tso cai rau lawv txav mus raws qhov ntev ntawm tus choj tau tsim. Qhov kev txav mus los no ua rau lawv mus txog ntau qhov chaw ntawm qhov chaw tsim kho raws li xav tau.
Kev tsim kho ruaj khov: Muab cov khoom hnyav uas lawv tau ua thiab qhov xav tau ntawm kev tsim kho choj, cov cranes no tau tsim kom muaj zog thiab ruaj khov. Lawv tau tsim los siv cov ntaub ntawv zoo thiab tsim los tiv thaiv kev ua haujlwm hnyav.
Cov yam ntxwv kev nyab xeeb: Choj kev tsim kho gantry cranes tau nruab nrog ntau yam kev nyab xeeb kom ntseeg tau tias muaj kev noj qab haus huv ntawm cov neeg ua haujlwm thiab cov neeg ua haujlwm ntawm qhov chaw tsim kho. Cov no tuaj yeem suav nrog kev tiv thaiv overload, khawm nres thaum muaj xwm ceev, kev cuam tshuam kev nyab xeeb, thiab lub tswb ceeb toom.
Lifting thiab positioning choj Cheebtsam: Choj kev tsim kho cranes yog siv los nqa thiab tso ntau yam ntawm tus choj, xws li precast qhob kab teeb, steel girders, thiab choj decks. Lawv muaj peev xwm tuav cov khoom hnyav thiab muab tso rau hauv qhov chaw uas lawv tau xaiv.
Txhim kho choj piers thiab abutments: Choj siv cranes yog siv los txhim kho choj piers thiab abutments, uas yog cov kev txhawb nqa uas tuav tus choj lawj. Cov cranes tuaj yeem nqa thiab txo cov ntu ntawm cov piers thiab abutments rau hauv qhov chaw, ua kom muaj kev sib raug zoo thiab ruaj khov.
Tsiv formwork thiab falsework: Choj siv cranes yog siv los txav formwork thiab falsework, uas yog ib ntus lug siv los txhawb txoj kev tsim kho. Cov cranes tuaj yeem nqa thiab hloov cov qauv no raws li xav tau kom haum rau kev tsim kho.
Tso thiab tshem tawm scaffolding: Choj siv cranes yog siv los tso thiab tshem tawm scaffolding systems uas muab kev nkag tau rau cov neeg ua haujlwm thaum tsim kho thiab tu cov haujlwm. Cov cranes tuaj yeem nqa thiab tso lub scaffolding ntawm ntau theem ntawm tus choj, tso cai rau cov neeg ua haujlwm ua haujlwm nyab xeeb.
Khoom Siv Khoom: Thaum tsim tiav, cov ntaub ntawv tsim nyog rau kev tsim lub gantry crane tau txais. Qhov no suav nrog cov qauv hlau, cov khoom siv hluav taws xob, cov motors, cables, thiab lwm yam tsim nyog. Cov ntaub ntawv zoo yog raug xaiv los xyuas kom meej lub zog thiab kev ua haujlwm ntawm crane.
Fabrication ntawm cov khoom siv: Cov khoom siv ntawm tus choj gantry crane, nrog rau cov nqaj loj, ob txhais ceg, thiab cov qauv txhawb nqa, yog tsim. Cov kws txawj welders thiab fabricators ua hauj lwm nrog cov qauv steel los txiav, puab, thiab vuam cov khoom raws li tus tsim specifications. Kev tswj xyuas kev ua tau zoo yog siv los ua kom muaj kev ncaj ncees ntawm cov crane.
Kev sib dhos thiab kev sib koom ua ke: Cov khoom tsim cov qauv tsim tau sib sau ua ke los ua lub hauv paus ntsiab lus ntawm tus choj gantry crane. Ob txhais ceg, lub ntsiab nqaj, thiab cov qauv txhawb nqa tau txuas nrog thiab txhawb nqa. Cov khoom siv hluav taws xob, xws li lub cev muaj zog, tswj vaj huam sib luag, thiab cov xaim hluav taws xob, tau muab tso rau hauv crane. Cov yam ntxwv kev nyab xeeb, xws li txwv cov keyboards thiab cov khawm nres thaum muaj xwm ceev, raug teeb tsa.
Txhim kho Lifting Mechanism: Lub lifting mechanism, uas feem ntau muaj xws li hoists, trolleys, thiab kis kab teeb, yog ntsia rau ntawm lub ntsiab nqaj ntawm lub gantry crane. Lub lifting mechanism yog ua tib zoo ua raws thiab ruaj ntseg kom ntseeg tau tias du thiab meej lifting hauj lwm.
