Industrial arung arai ni a ginra hta, lahkawng ngu na-}ndhand ni gaw, manu kaba ai a majaw, grai myit lawm wa ai. Hka hkin gau, gawgap ai shara (sh) jak rung bungli galaw ai shara rai tim, crane a hkrang bung sumla gaw shi a bungli galaw ai lam hte jai lang mai ai lam hpe hkrak hkra hkra machyi shangun ai. Second{4}}}d cranes ni a hkrang bung sumla ni hpe chye na ai gaw, mari ai ni hpe jak rung masa hte jai lang mai ai mabyin masa ni hpe grau hkrak hkra jep joi lu na matu karum ya na re.
1. Yawng hkra hkrang masa hte galu kaba ai lam
Second{0}}}}d a hkrang hpe shawng nnan shi a hkrang bung sumla hta madun dan ai. Crane amyu myu hta bridge crane, gantry crane, tower crane, etc. ni lawm nna, n bung ai amyu ni a hkrang gaw grai shai ai. Bridge crane ni gaw, madung n-gang, jahtum nhtoi hte hkawm sa ai ladat ni hte hpawng de da ai. Dai hkrang gaw galu kaba ai hte n-gun n rawng ai, nta kata (sh) gram lajang da ai lam ni a matu htuk manu ai; gantry cranes ni gaw chyinghka npawt nhpang hkrang ni hte bung ai, shinggan na n-gun hte jahkrat ai bungli ni a matu htuk manu ai, madung n-gang ni hpe madi shadaw ai outriggers ni; tower crane ni gaw towering tower structure nga ai rai nna, n-gun ja ai-rise hpe gawgap na matu htuk manu ai, shinggrup ai lata hte hpring tsup nga ai.
Size hte seng nna, lahkawng ngu na-}}} ai crane a hkrang nsam gaw, shi a sharawt ai n-gun hte bungli galaw ai radius hpe hkrak hkra hkra machyi shangun ai. Mari ai shaloi, dai arung arai ni hta galu kaba ai- aten a majaw, n-gun n-gun n-rawng ai lam ni nga ai kun ngu ai hpe myit maju jung ra ai, ga shadawn, main beam hpe shinggrup ai (sh) outriggers ni hpe tilting galaw ai zawn re ai ni hpe myit yu ra ai.
2. Ahkyak ai daw ni a dan dawng wa ai atsam .
Hook hte wire sumri: Dai shingkyit gaw crane a madung daw langai mi re. Shi a hkrang gaw n-gun n rawng ai hte n-gun n rawng ai rai ra ai. Wire sumri hpe n-gun n rawng ai (sh) n-gun n rawng ai hpe jep yu ra ai. Second langai a hook hpe ayan lang ai majaw lang mai ai, dai hpe laksan myit maju jung ra ai.
Hkrun lam hkawm ai leng ni hte lam ni: Hka lawng hte gantry crane ni a hkrun lam hkawm ai leng ni a hkrang gaw, n-gun n rawng ai sha, lam hkawm ai lam hte hkrak hkrak matut mahkai ra ai. Dai leng rim grai htum mat yang, n-gun n rawng ai bungli galaw ai lam byin chye ai.
Electrical control box: Hkrang nsam gaw, n-gun n rawng ai sumpu langai mi rai nga ai. Dai gaw n-gun n rawng ai kun, hkra machyi ai kun, kata na circuit gaw asak kaba ai kun ngu ai hpe jep yu u.
3. Laknak masat masa hte gram lajang ai masat kumla ni
Lahkawng ngu na-}}d crane a hkrang gaw shi a gram lajang ai masa hpe mung madun dan lu ai. High{2}} manu jahpu gaw, n-gun rawng ai, n-gun rawng ai, n-gun rawng ai n-gun rawng ai, n-gun ja ai welding daw hpe n-gun rawng ai, n-gun ja ai n-gun rawng ai. Dai hte maren, n-gun n rawng ai shara kaba langai mi nga ai rai yang, dai jak a ntsa e n-gun n rawng ai (sh) n-gun n rawng ai hpe welding galaw ai rai yang, shim lum lam hta hkrit tsang hpa ni nga chye ai.
4. Hpaga lam hte seng ai hpaji jaw ga ni
Lahkawng ngu na-hhand crane hpe mari ai shaloi, shara kaw nga ai arung arai ni a hkrang hpe jep yu nna, ra ai rai yang, hpaji ninghkring ni hpe jep joi na matu hpaji jaw ai. Structural integrity, ahkyak ai daw ni hpe bu hpun ai hte ra kadawn ai lam ni hpe hkan sa lu na matu, yawng hpe gram lajang ai masa hpe myit maju jung u.
Dai hkrang hpe atsawm sha yu ai hku nna, mari ai ni gaw, htuk manu ai second{0}}hhand crane ni hpe grau kaja hkra jep yu lu nna, mari ai lam hpe shayawm ya lu ai hte, jak rung ni hpe jai lang ai lam hpe grau kaja hkra galaw lu ai.
