I. Hnathawh dan chi hrang hrang leh a mamawh dan hriatchhuah .
Maintenance tools kan thlan hmain an hman tum leh an hman dan tur hriatthiam hmasak a pawimawh. Tool performance mamawh chu operation hrang hrangah a inang lo hle. Hnathawh dan chi hrang hrang hman tlanglawn te chu:
Rail cutting: Entirnan, rel thlak laiin rel chhe tawh siamthat
Sleeper drilling: Bolt, spike, leh fastener dahna tur
Rail grinding: rel chunglam a chhiatna awm thei te, corrugation leh crack te tihbo
Tamping: Sleepers hnuaia ballast compactness vawng reng leh track stability enkawl
Gauge leh gap tehna: Track geometry hmuhchhuahna .
Fastener dah leh lakchhuah: Spike leh bolt tihkhauh nan
II a ni. Hnathawh boruak leh hmun dinhmun ngaihtuah rawh .
Power awm theihna: Khawpui subway leh station area-ah chuan electric a awm tlangpui a, hei hian electric hmanrua hman theihna a siamsak a ni. Tlang leh pawn lama hnathawhna hmunah chuan chhung lam kangmei chhuahna hmanrua a ngai a ni.
Workspace: Confined space (tunnel ang chi) te hi low-noise, emission-free electric equipment atan a tha zawk.
Work intensity leh frequency: Long-Term, hman fo tan chuan hmanraw chhe thei lo duh zawk tur a ni. Lightweight portability hi a ngai a ni: Repair team emaw, aerial work emaw chu kut zungtang rit lo tak tak hmanrua atan a tha zawk.
iii a ni. Matching power type leh hmanrua performance te .
Rel kawng enkawlna hmanrua atan hian power chi hrang hrang pathum a awm a:
1. Electric .
A thatna: thawm hniam, exhaust emission awm lo, boruak tichhe lo leh thianghlim
A that lohna: Power supply emaw battery life tlem emaw a ngai
A hman theih tur chu: khawpui chhunga rel kal, tunnel, leh workshop enkawlna atana hman tur a ni.
2. Petrol/diesel hmanga siam a ni.
A thatna: Thiltithei tak, versatile, pawn lam power supply ngai lo
A that lohna: thawm ri nasa tak, emission sang tak, enkawlna complex tak tak
A hman theih tur chu: Off-road line, tlang rel kawng, leh emergency repairs te a ni.
3. Hydraulic/Pneumatic hmanrua .
A tlangpuiin hmanraw lian tak tak linkage emaw high-frequency, heavy-load construction, track tamping leh tensioning equipment ang chi te tan hman thin a ni. Hydraulic pump station emaw air compressor emaw hmanga hman a ngai. Hmanrua thlan hunah workload intensity leh power supply environment ngaihtuah la, power system-a a remchan dan leh a enkawlna senso kal mek chu uluk takin endik rawh.
iv. Rel kawng enkawlna hmanrua hman tlanglawn tak tak thlan chhuah
1. Rel hmanga kah theihna hmanrua .
Electric rail cutters: A rit lo va, boruak tichhe lo, khawpui subway leh routine maintenance atan pawh a tha.
Gasoline rail cutters: Thiltithei tak, electric leh high-intensity cutting operations awm lohna hmun atan a tha.
2. Drilling hmanrua .
Handheld drills (electric/internal combustion): Rail leh sleeper-a khur laih nan hman thin a ni. Model thlan hunah drill bit compatibility, cooling system, leh positioning accuracy te ngaihtuah rawh.
3. Thil hmanrua grinding .
Hand-Push grinders: flexible, corrugation siamthat leh rust lakchhuahna atana tha.
Specialized turnout grinders: Point rail leh switch ang chi hmun hrang hrang complex tak tak enkawlna atan a tha. Advanced needs atan chuan automated emaw vehicle-mounted grinding systems ngaihtuah rawh.
4. Tamping hmanrua te .
Electric/internal combustion tamping picks: Routine sleeper tamping leh maintenance atan a tha.
Tamping machine lian tak tak: Trackbed leh track leveling precision tamping atan hman a ni.
5. Track tehna hmanrua te .
Digital tools laser track gauges leh rail gap gauges te hi high-speed railways leh high-precision maintenance project atan a tha hle.
V. Hriselna leh certification lam ngaihtuah .
Specialized equipment angin rel hmanrua hian himna mechanism nghet tak a neih a ngai a ni:
Emergency stop device hmanga thuam a ni.
CRCC certification emaw rel kawng bureau kaihhnawih testing qualification emaw a ni thei.
Kangmei ven, puak thei-proof, leivut-proof, leh noise-Thil design tihtlem.
Standardized operating instruction leh training support te a awm bawk.
High-Equipment a tichak mai bakah hmanrua a chhiat avanga himna atana hlauhawm a awm loh nan a veng bawk.
