Ua haujlwm theem ntawm crane mechanism
Kev siv theem yog hais txog kev tsis khoom ntawm lub tshuab ua haujlwm. Nws muab faib ua 10 theem ntawm T0 txog T9 raws li tag nrho cov sij hawm ua haujlwm thaum lub sij hawm tag nrho cov kev pab cuam lub neej ntawm txhua lub tshuab. Lub xeev load qhia tau hais tias lub load degree ntawm lub mechanism muab faib ua plaub theem: lub teeb, nruab nrab, hnyav thiab hnyav ntxiv. Qib ua haujlwm tau muab faib ua 8 qib los ntawm M1 txog M8 raws li qib kev siv thiab lub xeev thauj khoom, raws li txoj cai kab pheeb ces kaum.
Ncua tseg crane
Ntawm no, nws yuav tsum tau taw qhia ua ntej tias theem ua haujlwm ntawm crane thiab nqa lub peev xwm ntawm crane yog ob lub ntsiab lus sib txawv. Lub peev xwm nqa tau hais txog qhov loj ntawm cov khoom nqa ntawm ib zaug, thiab qib ua haujlwm yog qhov ua haujlwm dav dav ntawm cov khoom siv crane. Cov qib ua haujlwm yuav tsis siab yog tias qhov hnyav nqa loj; qib ua haujlwm yuav tsis qis yog tias qhov nqa qhov hnyav me me. Txawm hais tias tib hom cranes nrog tib lub lifting hnyav muaj ntau theem ua haujlwm, qhov kev nyab xeeb ntawm cov khoom sib txawv. Yog tias koj tsuas saib lub lifting tonnage thiab tsis quav ntsej txog qib kev ua haujlwm, thiab siv lub crane nrog qib qis ua haujlwm tsis tu ncua thiab tag nrho cov load, nws yuav ua rau kom cov khoom tawg yooj yim, ua rau tsis zoo, thiab tseem ua rau muaj xwm txheej.
Tsis tas li ntawd, nws yuav tsum raug sau tseg tias qib ua haujlwm ntawm cranes thiab cov qauv hlau sib txawv los ntawm qib ua haujlwm ntawm lub tshuab. Rau tib lub crane, vim qhov tsis sib xws ntawm cov khoom thauj ntawm txhua lub tshuab ua haujlwm thiab lub sijhawm ua haujlwm tsis sib xws, txawm tias tib lub crane, kev ua haujlwm ntawm cov txheej txheem sib txawv feem ntau tsis sib haum nrog qib ua haujlwm ntawm crane. Qhov no yuav tsum tau them nyiaj tshwj xeeb rau thaum cov khoom sib txawv ntawm cov txheej txheem sib txawv thiab hloov kho.
Zuag qhia tag nrho ua haujlwm theem ntawm crane:
Qib ua haujlwm ntawm crane yog qhov ntsuas qhov qhia txog kev ua haujlwm hnyav ntawm lub crane, uas yog, qhov ntsuas qhov qhia txog kev ua haujlwm hnyav ntawm crane nyob rau lub sijhawm thiab tag nrho cov load. Hom nuv yog muab faib ua peb theem thiab xya yam: A1-A3 (lub teeb); A4-A5 (nruab nrab); A6-A7 (hnyav). Lub teeb (A1-13): tsis tshua muaj nqa cov khoom siv thauj khoom, feem ntau nqa lub teeb thauj khoom, feem ntau yog siv rau kev teeb tsa thiab kev saib xyuas cov khoom siv hauv cov chaw nres tsheb fais fab lossis lwm qhov chaw ua haujlwm, lossis chaw ua haujlwm thiab chaw khaws khoom uas tsis siv ntau zaus.
Intermediate (A4-15): qee zaum nqa lub nra hnyav, feem ntau nqa cov khoom nruab nrab, siv hauv kev cob qhia thiab chaw nres tsheb nrog kev ua haujlwm hnyav, xws li kev ua haujlwm dav dav thiab kev sib dhos ua haujlwm.
Hnyav qib (A6-A7): Rated load feem ntau yog lifted, feem ntau hnyav loads yog lifted, thiab nws yog siv nyob rau hauv lub workshops thiab warehouses nrog hnyav ua hauj lwm, xws li nquag lifting hnyav loads ntev thiab siv nyob rau hauv kev cob qhia metallurgical.
