Gawgap mawdaw ni gaw, gap bungli, lam galaw ai, lung seng htu ai, kaga engineering bungli ni hta grai lang ai laksan mawdaw ni rai nga ai. Shanhte gaw amyu myu nga ai rai nna, langai hte langai hta laklai ai bungli hte arawn alai ni nga ai. Lawu na hta, n-gun ja ai gap hkat jahkring ai mawdaw amyu nkau mi hpe hkrak tup tsun dan da ai.
1. Htu shaw ai jak
Excavator ni gaw, ga, nhprang wan, lung seng zawn re ai arung arai ni hpe htu shaw na matu madung lang ai, gap hkat jahkring ai mawdaw langai rai nga ai. Htu shaw ai jak ni hpe shanhte hkawm sa ai ladat hku nna crawler htu shaw ai jak hte leng htu shaw ai jak ngu nna garan ginhka da ai. Excavator ni hta madung hku nna power unit, bungli galaw ai jak, slewing ladat, hkang ai ladat, htawt sit ai ladat, hkawm sa ai ladat ni lawm ai. Shanhte hpe bungli galaw ra ai lam amyu myu hte htap htuk hkra bungli galaw ai arung arai amyu myu hpe bang mai ai. Hka htung gap ai lam, lam galaw ai lam, lung seng htu ai lam ni zawn re ai bungli amyu myu hta htu shaw ai jak ni gaw n mai malap ai lit nga ai.
2. Loader
Loader ni gaw, lam kaba, wanleng lam, nta ni, hka wan jak, sanghpaw daru, lung seng htu ai shara ni zawn re ai gawgap bungli ni hta grai lang ai ga npu hpe htu ai jak ni rai nga ai. Shanhte hpe madung hku nna ga, nhprang wan, nlung npan, nhprang wan n-ga, nhprang wan n-ga zawn re ai n-gun kaba ai arung arai ni hpe htaw bang na matu lang ai rai nna, nhprang wan n-ga hte n-gun ja ai ga ntsa hta n-gun n rawng ai htu shaw ai bungli ni hpe mung galaw lu ai. Loader ni hpe gawgap bungli amyu myu hta grai lang ma ai, hpa majaw nga yang, shanhte gaw lawan ai, n-gun ja ai, n-gun ja ai, n-gun ja ai, galaw na matu loi ai.
3. Lam Roller
Road roller ngu ai gaw ga hte lam ntsa hpe shinggrup na matu lang ai gawgap jak langai mi re. Shi a bungli galaw ai ladat gaw, jak a n-gun (gravity) hte n-gun (vibration) hpe lang nna, n-gun hpe n-gun jat hkra galaw na matu re. Lam roller ni gaw, gawgap jak rung ni a kata na lam arung arai ni a hpan hta lawm nna, lam kaba, wanleng lam, nbungli pa, hka htung ni, ginsup pa ni zawn re ai-bungli kaba ni hta hka jahpring ai hte shinggrup ai bungli ni hta grai lang ma ai. Shanhte gaw nhprang n-gun rawng ai, daw mi-n-gun rawng ai, hte n-gun rawng ai ga ni, lam npu hpe n-gun jaw ya ai, asphalt concrete n-gun rawng ai ga ni hpe shinggrup lu ai. Lam hkawm ai roller ni hpe madung hku nna static hte vibrating ngu ai lahkawng hku garan nna galaw ai. Shanhte gaw n-gun kaba ai, n-gun kaba ai, asan sha galaw lu ai atsam nga ai.
4. Motor Grader
Motor grader ngu ai gaw, ga hpe n-gun dat na matu, n-gun dat ai jak langai re. Shaping hte leveling galaw ai lam lahkawng yan hta lang mai ai. Motor grader hta madung hku nna engine, transmission system, hkrun lam hkawm ai ladat, bungli galaw ai ladat, wan jak ladat ni lawm ai. Bungli galaw ai shaloi, motor grader a scraper gaw, n-gang hpe shinggrup, shamu shamawt, nhtang wa ai hku nna, ra ai shara de ga hpe htu nna, htaw sa nna, jahpring ya ai majaw, dai shara hpe maren mara byin hkra galaw ai. Motor grader ni gaw lam, hka htung, nbungli pa zawn re ai engineering bungli kaba ni hta ahkyak ai lit nga ai.
