Qhov sib txawv tseem ceeb ntawm Gooseneck semi-trailer thiab cov kab ncaj nraim semi-trailer nyob rau hauv lawv cov girder tsim thiab chaw thau khoom yooj.
Ib txoj kab ncaj nraim semi-trailer, tseem hu ua "ncaj phaj" semi-trailer, nta cov qauv girder uas ua rau txoj kab ncaj nraim. Qhov yooj yim thiab meej tsim no ua rau nws yooj yim rau kev tsim thiab tswj. Vim nws txoj kev tsim ncaj nraim, tus nqi qis kuj yog ib qho kev xaiv rau kev thauj mus los. Ib txoj kab ncaj nraim semi-trailer yog tsim rau thauj ntau yam khoom, tshwj xeeb tshaj yog thaum thauj khoom qhov chaw yuav tsum tsis txhob siab, vim nws muab kev thauj mus los zoo.
Hauv qhov sib piv, Gooseneck semi-trailer muaj "Z"-puab girder qauv, uas yog vim li cas nws tseem hu ua "siab thiab qis phaj" semi-trailer. Qhov kev tsim no tsim qhov siab sib txawv ntawm lub hauv paus phaj thiab gooseneck, feem ntau nyob ib ncig ntawm 200 mm. Cov qauv no tso cai rau qhov chaw thau khoom ntau dua thiab yooj yim dua nyob rau hauv cov nqe lus ntawm qhov siab ntawm cov khoom thauj. Tsis tas li ntawd, qhov qis nruab nrab ntawm lub ntiajteb txawj nqus ntawm cov khoom thauj ua rau gooseneck semi-trailer ruaj khov thaum tsav tsheb, txhim kho kev nyab xeeb.
Yog li ntawd, cov kab ncaj nraim semi-trailer yog qhov yooj yim thiab siv tau zoo, tsim nyog rau cov xwm txheej uas tsis tshua muaj chaw thau khoom. Hauv qhov sib piv, gooseneck semi-trailer, nrog nws cov qauv "Z" tshwj xeeb, muaj kev yooj yim dua hauv chaw thau khoom thiab txhim kho kev tsav tsheb, ua rau nws zoo tagnrho rau kev thauj mus los uas xav tau ntau dua cov khoom thauj khoom yooj yim.
