Cov kav dej Crane yog qhov tseem ceeb heev hauv kev thauj mus los niaj hnub, vim tias kev thauj mus los yuav ntsib cov tshuaj lom neeg thiab yuav muaj kev pheej hmoo. Yog li ntawd, xav tau cov kav dej crane. Kev ruaj ntseg yeeb nkab crane tseem tuaj yeem txhim kho kev ua haujlwm. Ntawm chav kawm, qhov twg lub raj crane yuav siv tau yog nyob ntawm qhov nruab nrab uas tau thauj thiab yam khoom xa tuaj twg siv rau. Kuj muaj ntau lub zos nqaum hauv Suav teb. Cov chaw nres nkoj thiab cov piers yog qhov chaw nyob ua ntej rau kev lag luam tawm. Yog tias koj thauj cov kua tshuaj, siv cov hlab raj. Nws yog qhov zoo dua los xyuas kom muaj kev nyab xeeb tsis muaj kev ploj thiab txhim kho kev ua haujlwm. Qhov tseem ceeb tshaj plaws ntawm cov yeeb nkab crane yog cov sib koom ua ke. Nws thawj cov kev txiav txim siab yog:
(1) PTFE polytetrafluoroethylene khoom yog xaiv, thiab lub ntsej muag sealing yog polished ua kom nws hnav-resistant, corrosion-resistant, acid thiab alkali resistant.
(2) Crane tube teb sib koom tes yog tsuas yog tsim ntawm lub nplhaib puab, sab hauv lub nplhaib sib dhos, foob, dov steel pob (kabmob) thiab txuas cov ntsia hlau.
(3) Lub tog raj kheej pob yeeb sib koom tes tau ua tib zoo laij kom ua tib zoo kom lub chaw thau khoom thiab thau khoom kom txaus siab rau qhov sib npaug ntawm qhov xav tau ntawm lub ntees, thiab kev ua haujlwm sib dhos yog lub teeb thiab yooj yim.
(4) Lub tog raj crane tig lub pob qij txhawm rau txhim kho cov qhov tso tawm lub zog, thiab qhov tso tawm qhov tso tawm tau ua raws li lub cev muaj zog cov txiaj ntsig los ntawm qhov kev txo qis, tab sis nws yuav tsum raug sau tseg tias qhov ntxiv qhov siab ntawm qhov txo qis tsis tuaj yeem tshaj.
(5) Kev txiav txim siab uas cov hlau tsis muaj cov khoom tuaj yeem tuaj yeem nqus cov poob siab thiab kev co ntawm cov khoom siv, tiv thaiv kom tsis txhob rov hnav dua, thiab ntev txuas ntxiv rau kev pab lub neej ntawm cov khoom siv.
