Cov kev xav tau rau cov muag muag- teeb pom kev yog feem ntau tshwm sim nyob rau hauv plaub qhov tseem ceeb: cov khoom ua tiav, lub zog ntawm cov qauv, kev kho saum npoo, thiab kev sib dhos zoo; sib sau ua ke, cov xwm txheej no txiav txim siab qhov kev ruaj ntseg thiab kev pabcuam lub neej.
Hais txog kev ua cov khoom siv, cov khoom no feem ntau siv aluminium alloys lossis steel, uas tau dhau los ua kev txiav, xuas nrig ntaus, thiab tsim cov haujlwm kom ntseeg tau tias qhov sib xws ntawm cov ntu thiab qhov zoo meej haum ntawm cov pob qij txha. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog rau telescopic lossis segmented cov qauv, qhov kev tswj hwm nruj yog qhov tseem ceeb los tiv thaiv cov teeb meem xws li jamming lossis loosening.
Hais txog lub zog ntawm cov qauv, cov txheej txheem tsim khoom yuav tsum ua kom cov phab ntsa tuab tuab thiab sib koom ua ke ntawm cov khoom tseem ceeb ntawm cov khoom tseem ceeb -cov ntsiab lus bearing-tshwj xeeb ntawm kev sib txuas ntawm qhov sib txuas thiab cov tshuab xauv. Cov cheeb tsam no feem ntau xav tau cov qauv tsim tshwj xeeb los tiv thaiv cov khoom tsis tu ncua los ntawm cov khoom siv teeb pom kev zoo thiab muag muag - lub teeb hloov kho, yog li tiv thaiv deformation lossis qaug zog puas tsuaj rau lub sijhawm siv ntev.
Hais txog kev kho saum npoo, mos- lub teeb sawv ntsug feem ntau dhau los ua cov txheej txheem xws li anodizing, hmoov txheej, lossis electrophoretic painting los txhim kho corrosion kuj thiab abrasion durability, thaum tib lub sijhawm txhim kho kev zoo nkauj. Kev kho saum npoo zoo kuj tseem pab txo qis qhov khawb thiab oxidation, yog li txhim kho qhov chaw muag khoom kom haum rau kev siv sab nraum zoov.
Raws li kev sib dhos, kev sib dhos meej ntawm cov xov sib txuas, snap-lock mechanisms, thiab cov khoom siv xauv yog qhov tseem ceeb los xyuas kom meej tias kev teeb tsa du, ruaj ntseg, thiab txhim khu kev qha. Tsis tas li ntawd, ua ntej tawm hauv lub Hoobkas, txhua qhov chaw sawv ntsug feem ntau ua rau cov khoom thauj -cov kabmob thiab kev ntsuas kev ruaj ntseg kom lav nws txoj kev nyab xeeb thiab kev ntseeg tau raws li kev ua haujlwm tiag tiag.
