Dab tsi yog kis ntauwd pej thuam?

Kev Hloov Cov yees yog cov chaw teeb hluav taws xob tshwj xeeb siv los txhawb nqa cov xov hlau thiab cuam tshuam. Lawv yog ib feem tseem ceeb ntawm cov hluav taws xob cov kab thiab ua kom cov kis tau zoo thiab nyab xeeb ntawm hluav taws xob hluav taws xob. Tus qauv ntawm kev sib kis ntauwd pej thuam feem ntau muab faib ua peb ntu loj: Lub taub hau ntauwd, lub pej thuam lub cev thiab cov pej thuam ob ceg. Lub taub hau ntauwd yog txoj haujlwm uas cov pej thuam qhov chaw hloov pauv, thiab ntau txhiab ceg yog thawj ntu ntawm lub pej thuam nyob rau ntawm lub hauv paus.

Kev xa cov yees thev naus laus zis muaj ntau yam duab, thiab cov nquag yog "Miv taub hau ntauwd" thiab "iav caw ntauwd". Cov npe no tsuas yog cais los ntawm cov qauv sib txawv ntawm cov pej thuam ntauwd. Cov ntsiab lus tseem ceeb ntawm cov neeg saib xyuas kis tau xws li cov neeg ua haujlwm, cov xov hlau overhead av (xob laim hluav taws xob (xws li cov hlau clamps, thiab lwm yam). Cov neeg saib xyuas yog lub luag haujlwm rau kev coj ua tam sim no thiab hloov hluav taws xob tam sim no, thiab lawv tus lej yog cuam tshuam nrog cov kis kev sib txuas ntawm cov kab.

 

Cov ntaub ntawv ntawm kis kis ntau zaus feem ntau siv ob hom kaum ob lub kaum steel, Q235 (A345 (16mn). Cov pas nrig txuas nrog los ntawm cov nqaj hlau. Tag nrho cov pej thuam yog tsim ntawm lub kaum ntse ntse steel, txuas hlau daim hlau thiab bolts. Rau cov yees nrog qhov siab tsawg dua 60 metres, txhais ko taw cov ntsia hlau ib txwm tau teeb tsa tus neeg tseem ceeb ntawm cov pej xeem los pab txhawb kev tsim kho thiab txij nkawm.
