Thaum muas hoisting machinery, cov tuam txhab lag luam yuav tsum ua tib zoo xav txog cov yam ntxwv xws li kev npaj siv, kev siv ntau zaus, kev siv tus nqi, thiab cov peev txheej nqa, txhawm rau xaiv lub crane nrog cov chav ua haujlwm uas ua tau raws li cov kev xav tau tshwj xeeb ntawm lawv lub koom haum.
Raws li cov txheej txheem tsim, kev tshawb fawb kev lag luam yuav tsum tau ua. Tus neeg muag khoom xaiv yuav tsum yog lub chaw tsim khoom tshwj xeeb crane tuav daim ntawv tso cai kev nyab xeeb rau cov cuab yeej tshwj xeeb.
Tsis tas li ntawd, nws yog ib qho tseem ceeb rau kev soj ntsuam cov chaw tsim khoom cov cuab yeej ua haujlwm, kev tsim qauv tsim khoom, thiab cov khoom siv thev naus laus zis. Tom qab ua cov kev sib piv no, qhov kev xaiv zaum kawg yuav tsum yog lub tshuab hoisting uas muaj tus nqi tsim nyog, kev ua tau zoo, kev ua tau zoo dua, thiab cov khoom siv dav dav ntawm kev nyab xeeb.
Thaum tuaj txog ntawm cov cuab yeej, thaum lub sij hawm unpacking thiab txais kev soj ntsuam, nws yog tsim nyog los xyuas kom meej tias tag nrho cov accompanying cov ntaub ntawv yog tiav; uas suav nrog cov khoom seem, cov cuab yeej, thiab cov khoom siv sib txuas nrog cov npe ntim khoom; thiab hais tias tsis yog cov cuab yeej siv los yog nws cov khoom tsis pom muaj kev puas tsuaj lossis qhov tsis xws luag. Cov ntaub ntawv ntxaws ntxaws ntawm qhov kev tshem tawm thiab kev lees paub qhov kev kuaj xyuas no yuav tsum tau khaws cia kom raug.
