Nyiaj siv ua haujlwm cranes yog ib hom khoom nqa nqa uas feem ntau siv hauv kev tsim khoom, kev tsim kho, kev tsim khoom, thiab lwm yam lag luam uas yuav tsum tau ua kom muaj zog ntawm cov khoom hnyav. Yog li ntawd, muaj kev cai nyiaj siv ua haujlwm crane tsim rau cov kev xav tau tshwj xeeb yog qhov tseem ceeb rau koj txoj kev lag luam.
Classification ntawm choj cranes
Kev faib tawm los ntawm cov qauv: xws li ib-nqaj choj crane, ob-beam choj crane, underslung crane, ob-trolley choj crane, ntau-trolley choj crane, thiab lwm yam.
Kev faib tawm los ntawm kev nqa khoom: xws li nuv crane, rub crane, electromagnetic crane, thawv crane, thiab lwm yam.
Kev faib tawm los ntawm lub hom phiaj: xws li chaw ua haujlwm crane, dav dav crane, metallurgical crane, tawg-pov thawj crane, thiab lwm yam.
Cov khoom tseem ceeb ntawm choj cranes
Nyiaj siv ua haujlwm cranes yog tsim los ntawm ob peb yam tseem ceeb uas ua haujlwm ua ke kom ntseeg tau tias cov khoom siv tau yooj yim thiab txhim khu kev qha. Cov khoom tseem ceeb muaj xws li:
Choj: Tus choj yog lub ntsiab kab rov tav kab uas hla qhov dav ntawm qhov chaw. Nws txhawb nqa lub hoist thiab pab txhawb kev txav ntawm lub nra.
Cov cuab yeej nqa: Cov cuab yeej nqa nqa yog lub luag haujlwm rau kev nqa thiab txo qis, xws li crane. Nws txuas nrog tus choj thiab txav mus raws tus choj, tso cai rau cov khoom thauj kom raug.
Xaus ncej: Cov ncej kawg yog nyob rau ntawm ob qho kawg ntawm tus choj thiab khiav ntawm txoj kev. Lawv txhawb nqa tus choj qauv thiab muab kev ruaj ntseg thaum lub crane txav.
Cov cuab yeej tswj hwm: Cov cuab yeej tswj tau ua rau tus neeg teb xov tooj ua haujlwm ntawm crane thiab tswj kev nqa, txo qis thiab txav ntawm lub nra. Niaj hnub nimno cranes feem ntau siv cov txheej txheem tswj hwm los txhim kho qhov tseeb thiab kev nyab xeeb.
Yuav tsim tus choj crane li cas?
Ntawm no yog ib qho piv txwv ntawm kev tsim tus choj crane:
Txiav txim siab qhov ntsuas ntawm tus choj crane:
Lifting peev: yog hais txog qhov hnyav ntawm qhov nqa qhov hnyav, hauv kilograms lossis tons, thiab suav qhov hnyav tshaj plaws uas lub crane xav tau nqa.
Lifting qhov siab: yog hais txog qhov kev ncua deb ntawm qhov nruab nrab ntawm tus nuv thiab hauv av.
Choj crane ncua: yog hais txog qhov kev ncua deb ntawm cov kab nruab nrab ntawm ob txoj kab ntawm tus choj crane khiav khiav, uas yog hu ua qhov ncua ntawm lub crane.
Kev ua haujlwm theem: Cov xwm txheej ua haujlwm yog qhov ntsuas ntawm tag nrho lub tshuab, qhia txog qhov ntsuas tag nrho ntawm lub crane nqa nqa thiab tus lej ntawm kev nqa haujlwm. Qib ua haujlwm crane tau muab faib ua yim theem ntawm A1 txog A8, los ntawm lub teeb (A1-A3) mus rau hnyav ntxiv (A8).
Tsis tas li ntawd, koj yuav tsum tau txiav txim siab qhov chaw ua haujlwm. Xav txog yam xws li kub, av noo, thiab muaj cov khoom phom sij.
Tsim qauv:
Xam qhov loj thiab lub zog ntawm cov khoom siv crane xws li girders, kab, thiab cov kab hluav taws xob khiav.
Xav txog yam xws li cov khoom siv zog, qaug zog tiv thaiv, thiab yam muaj kev nyab xeeb.
Nrog rau cov qauv tsim tshwj xeeb thiab cov qauv, xws li CMAA (Crane Manufacturers Association of America) lossis cov cai hauv zos.
Txiav txim siab lub lifting mechanism:
Xaiv qhov tsim nyog lifting system (hlau hlua hoist, saw hoist, thiab lwm yam) raws li qhov yuav tsum tau ua.
Xam qhov yuav tsum tau nqa ceev, acceleration thiab deceleration.
Xav txog cov yam ntxwv kev nyab xeeb xws li txwv cov keyboards, khawm nres thaum muaj xwm ceev thiab cov khoom siv tiv thaiv overload.
European hlau hlua hoist 5 tons HD European ib leeg nqaj crane
Xaiv qhov system tswj:
Xaiv ib phau ntawv, semi-automatic lossis tag nrho tsis siv neeg tswj qhov system.
Xav txog tus neeg teb xov tooj interface, kev nyab xeeb nta thiab kev koom ua ke nrog lwm yam khoom siv.
Teb Spreader NLH 32 tons ob chav nqaj crane slewing spreader export Mexico
Xav txog cov kev xav tau ntawm hluav taws xob thiab lub zog:
Txiav txim siab cov khoom siv hluav taws xob (voltage, zaus) thiab hom kev xa hluav taws xob (cable drum, festoon system, conductive pas nrig).
Xam cov khoom siv hluav taws xob thiab qhia cov khoom siv hluav taws xob tsim nyog (lub cev muaj zog, tswj, cable, thiab lwm yam).
Ntsuas cov yam ntxwv kev nyab xeeb:
suav nrog kev ntsuas kev nyab xeeb xws li txwv kev hloov pauv, khawm nres thaum muaj xwm ceev, cov khoom siv tiv thaiv overload thiab thaiv kev nyab xeeb.
Xav txog kev nyab xeeb ntawm cov neeg ua haujlwm thaum lub sijhawm ua haujlwm crane thiab tu.
Ua raws li kev txheeb xyuas cov qauv:
Siv engineering software los txheeb xyuas cov qauv crane thiab xyuas kom meej tias nws tuaj yeem tiv taus qhov kev cia siab ntawm kev thauj khoom thiab quab yuam.
Txheeb xyuas qhov ruaj khov, kev faib tawm kev ntxhov siab, thiab deflection ntawm cov khoom tseem ceeb.
Tsim cov duab kos kom ntxaws:
Npaj kom ntxaws fabrication thiab sib dhos drawings, nrog rau tag nrho cov tsim nyog qhov ntev thiab specifications.
Xws li kev sib dhos ua ntu zus, vuam cov ntsiab lus, thiab cov khoom specifications.
Prototype thiab kuaj:
Tsim ib tus qauv ntawm lub crane thiab ua qhov kev ntsuam xyuas kom paub tseeb tias nws qhov kev ua tau zoo, kev ua haujlwm, thiab kev nyab xeeb.
Ua ib qho kev hloov kho lossis kev txhim kho uas tsim nyog raws li qhov kev xeem tau.
Nws yog tsim nyog sau cia tias tsim ib qho nyiaj siv ua haujlwm crane yuav tsum muaj kev txawj ntse hauv kev tsim qauv engineering, mechanical engineering, thiab hluav taws xob engineering. Xav txog kev sab laj nrog tus kws tshaj lij lossis cov chaw tsim khoom crane kom muaj kev nyab xeeb thiab siv tau zoo. Thaum koj tau txheeb xyuas cov kauj ruam no, koj yuav tsum npaj kho koj tus kheej nyiaj siv ua haujlwm crane.
