Nws yog tsim los ntawm lub tsheb chassis, sib xyaw lub tog raj kheej, xa cov khoom siv, cov khoom siv dej, lub zog siv hluav taws xob tag nrho, txhawb nqa ua ntej thiab tom qab sib xyaw lub tog raj kheej, txo qis, kaw lus kaw lus hydraulic, cov khoom nkag thiab qhov hluav taws xob, tswj lub tshuab thiab lwm yam. Vim tias muaj kev cuam tshuam tsis zoo, cov tsheb tso tsheb sib tsoo hauv tsev nrog ntim ntawm 3m³-8m³ txais yuav plaub qhov loj hauv tsev, thaum cov uas muaj ntim ntau dua 8m³ feem ntau siv cov khoom xa tuaj.
Cov khoom sib xyaw: chav kawm thib ob chassis, kev xa xov, hydraulic system, thav duab, sib xyaw tank, pub khoom thiab tso tawm, dej system, tswj qhov system, ntaiv thiab lwm yam. Pem hauv ntej kawg ntawm lub tank sib txuas tau txuas nrog tus txo qis thiab teeb tsa rau pem hauv ntej kawg ntawm cov khib, thiab qhov kawg tom qab tau txhawb nqa los ntawm ob lub log txhawb nqa nruab rau tom kawg ntawm lub khib los ntawm txoj kev sib tw.
