Rel Lifting Jacks chungchang hriattirna .
Rail lifting jack, track lifting jack emaw rel kawng jack tia hriat bawk hi tunlai rel enkawlna atana hmanraw pawimawh tak a ni. Anni hian rel leh sleeper te him taka chawi theih an ni a, track engineer te chu alignment correction, gauge adjustment, ballast thlak, leh emergency track siamthat te an ti thei a ni. Heng jack te hi a chhe thei lo, a nghet thei tur, leh a thawhrimna tur atana siam a ni a, manual leh mechanized track maintenance operations te pawh a support thei bawk.
Rail lifting jack-a hnathawh dan tur (working principle) .
- Mechanical lama hmasawnna:Manual jack-ah chuan screw, lever, gear hmangin rel leh sleeper lifting atan mihring chakna chu a pung a ni.
- Hydraulic Force Multiplication:Hydraulic jack hian pressurized fluid hmangin lifting capacity sang tak a neih theih nan theihtawp a chhuah tlem ber a ni.
- Load sem dan: 1.1.Specialized base plate leh lifting pads te hian track emaw sleeper emaw a chhiat loh nan rel rit chu a insem darh vek theih nan a enkawl a ni.
- Precision control dan tur: 1.1.Adjustable height leh pressure hian fine alignment leh gauge correction a phal a, components overload lovin.
Rail lifting jack chi hrang hrang leh a mechanism te .
- Manual (Mechanical) Jacks:Portable, human-powered jacks te chu hmun hla tak takah siamthatna tenau leh emergency maintenance atan a tha.
- Hydraulic jack te chu:kut emaw electric pump hmanga power pek; Rail rit tak tak tha taka chawi thei. Large-scale track enkawlna atan a tha hle.
- Single-Rail vs dual-rail:Single-Rail jack te hian rail pakhat khatin an chawi a, dual-rail jack te hian track section pum pui chu a rualin an chawi thei thung.
- Hand-Pump vs electric pump:Duhthlanna chu site power awm theihna leh hman dan a zirin a innghat a ni.
