Qhov sib nrug ntawm ob ncej ntawm ob - ncej tsheb nqa yog dab tsi? Vim li cas?
Qhov kev ncua deb ntawm ob ncej ntawm ob - ncej tsheb nqa yog feem ntau ntawm 2.7 meters thiab 3.1 meters (kwv yees li 110-122 ntiv). Cov txheej txheem feem ntau yog qhov chaw nruab nrab - mus rau nruab nrab ntawm kwv yees li 2.8 meters (112 ntiv tes), tab sis tus nqi tseeb nyob ntawm tus qauv.
Vim li cas qhov kev ncua deb?
1. Kom haum rau qhov dav ntawm cov tsheb feem ntau. Cov neeg caij tsheb niaj hnub no yog 1.7-2.0 meters dav, thaum SUVs thiab lub teeb tsheb thauj khoom tuaj yeem ncav cuag 2.1 meters. Qhov kev tshem tawm ntawm kwv yees li 40-50 centimeters ntawm txhua sab ntawm lub tsheb nqa tso cai rau kev nqa caj npab kom yooj yim mus txog qhov tsim nyog nqa.
2. Tso cai rau kev txav caj npab hloov tau yooj yim. Ob - lub tsheb nqa nqa siv lub viav caj npab kom ncav cuag lub tsheb nqa qhov taw qhia.
Yog tias cov ncej ntawm ob - ncej tsheb nqa tau ze dhau ua ke:
Lub caj npab lifting tsis tuaj yeem txuas tau zoo. Cov tsheb loj kuj yuav nkag tsis tau.
Yog tias qhov uprights dav dhau lawm: cov tsheb me tsis tuaj yeem ncav cuag ob lub ntsiab lus nqa. Lub lifting caj npab yuav overextend, ua rau kom txo tau lub peev xwm nqa. Nws tuaj yeem yooj yim ua rau nqa caj npab kom deform. Yog li ntawd, qhov sib nrug ntawm kwv yees li 2.8 meters yog qhov pom kev sib haum xeeb.
3. Kev ruaj ntseg zoo
Lub hauv paus phaj lossis crossbeam ntawm lub tsheb nqa yuav tsum muaj qhov dav txaus kom tswj tau qhov rigidity ntawm uprights. nqaim dhau yuav txo qhov ruaj khov; dav dhau yuav ua rau kom lub sijhawm khoov thiab kev ntxhov siab ntawm cov uprights thiab thauj tog rau nkoj bolts.
4. Kev sib raug zoo nrog cov qauv kev lag luam
Cov neeg tsim khoom tsim lub tsheb nqa kom haum rau: ntau hom tsheb me, suav nrog sedans, SUVs, MPVs, tsheb thauj khoom, thiab lwm yam.
Yog li ntawd, qhov sib nrug yog standardized hla ntau hom.
