Qhia Txog Cov Kev Xav Tau: Nkag siab txog cov saw hlau xav siv (lifting? kis? khi?), qhov siab tshaj plaws uas nws yuav tsum tau tiv taus (ua haujlwm load, qhov kawg load), thiab qhov chaw ua hauj lwm (corrosion, kub, plua plav, thiab lwm yam).
Xaiv Yam Tsim Nyog thiab Qib: Xaiv cov saw hlau uas tsim nyog thiab qib muaj zog txaus (kev nyab xeeb zoo) raws li qhov xav tau siv. Tshwj xeeb tshaj yog rau kev nqa cov haujlwm, siab - lub zog lifting chains ua raws li cov qauv (xws li ISO, DIN, GB) (G80 qib thiab siab dua) yuav tsum tau siv.
Tshawb xyuas qhov zoo: Tshawb xyuas cov saw hlau rau qhov tsis xws luag xws li tawg, deformation, hnav hnyav, thiab xeb. Xyuas kom meej tias cov cim qhia meej (feem ntau suav nrog cov chaw tsim khoom, qib, thiab cov lus qhia tshwj xeeb).
Kev tshuaj xyuas thiab tu tsis tu ncua: Kev tshuaj xyuas cov saw hlau tsis tu ncua thaum siv, ua lubrication thiab txij nkawm, thiab hloov cov saw hlau uas hnyav dhau los yog puas lawm.
Kev Ua Haujlwm Zoo: Ua raws li cov txheej txheem ua haujlwm thiab tsis txhob hla cov saw hlau. Cov haujlwm nqa nqa yuav tsum ua los ntawm cov neeg ua haujlwm tsim nyog.
