Puas yog tes saw hoist khoom tshwj xeeb?

Cov cuab yeej tshwj xeeb hais txog cov khoom siv ua haujlwm uas muaj kev txhawb nqa lub neej thiab muaj kev phom sij heev. Cov cuab yeej tshwj xeeb tau muab faib ua ob pawg: cov khoom siv tshwj xeeb siab-cov kabmob thiab cov khoom siv tshwj xeeb electromechanical. Rau kev lag luam lifting, nws yog pom tseeb tias nws belongs rau cov khoom siv electromechanical. hom khoom siv tshwj xeeb. Cov cuab yeej siv hluav taws xob tshwj xeeb yog siv rau kev nqa ntsug lossis cov khoom siv hluav taws xob uas nqa vertically thiab txav cov khoom hnyav horizontally. Yuav kom paub meej ntxiv, nws cov peev txheej tau txhais tau tias yog lub nqa nqa nrog lub peev xwm nqa tau ntau dua lossis sib npaug ntawm 0.5t thiab qhov ntsuas nqa lub peev xwm ntau dua lossis sib npaug li 3t thiab nqa qhov siab siab dua lossis crane sib npaug li 2m; los ntawm cov ntaub ntawv saum toj no, peb tuaj yeem pom tias cov saw hoist tsis yog cov cuab yeej tshwj xeeb. Ua tib zoo mloog lo lus "electromechanical", uas txhais tau hais tias nws yuav tsum tau ua nrog "hluav taws xob". Ntawd yog, lub npe hu ua hluav taws xob hoist, crane, thiab lwm yam. Cov ntaub ntawv saum toj no tsuas yog qhia tau hais tias cov saw hoist tsis yog cov cuab yeej tshwj xeeb. Txawm hais tias cov kev cai hais li ntawd, hauv qee thaj chaw ntawm lub tebchaws, covsaw hoistis suav tias yog cov cuab yeej tshwj xeeb thiab yuav tsum tau kuaj xyuas txhua xyoo.
