Construction industry-a equipment cost control mamawhna a san chhoh zel avangin second-hand concrete machinery market chu khawvel puma thil lei nan hmun pawimawh tak a lo ni ta a ni. Mixer emaw, pump truck emaw truck-mounted pump emaw pawh nise, second-kut hmanrua lei leh scientific taka hman hian investment man a tihhniam mai bakah, sakna lama a thawh thatna a tichiang thei bawk. He article hian industry practitioner-te tana practical reference pe turin second-hand concrete machinery-a thil lei thiamna, performance evaluation leh maintenance point-te a zirchiang ang.
1. Second -hand concrete machinery lei theihna core skills .
• Demand chiang tak leh budget .
A lei hmain hmanrua chi hrang hrang chu project scale angin a hriat a ngai a ni. Entirnan, project tenau te chuan cubic meter 50 aia tlem lo mixer an thlang thei a, infrastructure lian-scale chuan thil siam chhuah theihna sang zawk a mamawh thung. Budget chungchangah chuan maintenance mamawhna tur phuhruk nan maintenance fund 10%-15% reserve a tha.
• Hnathawh hun chhung ngaihven la, hmanrua℃ha la
Hnathawh hun chhung hi hmanrua nunna la awmte tehna atana hmanraw pawimawh tak a ni. A tlangpuiin, mixing host hnathawh hun chhung darkar 10,000 aia tam a nih chuan hydraulic system leh mixing arm wear te chu enfiah a ngai a ni. Chu bakah, a hnu lama replacement cost sang tak awm loh nan hopper guide leh conveyor belt ang chi vulnerable parts te wear℃en bawk ang che.
• Maintenance record leh certification document te en rawh .
Supplier-te chu maintenance log kimchang leh original certification document pe turin an ti a, engine leh hydraulic pump ang chi core components te chu siamthat a nih leh nih loh finfiah a tum bawk. Export hmanrua atan chuan target market-a emission standards a tlin leh tlin loh (European Tier 4 emaw US EPA certification ang chi) a tlin leh tlin loh finfiah a ngai a ni.
2. Performance evaluation leh test dan tur .
Machine hi site-a enfiah hunah core test pathum neih a tha:
No{{0}Load Operation Test : Equipment i tan hnuah hydraulic system pressure a nghet em tih leh a ri dik lo a awm leh awm loh enfiah rawh.
Load simulation test : Mixing uniformity leh discharge speed te hian nominal parameters an tlin leh tlin loh hriat theih nan standard proportion concrete dah belh.
Safety device verification verification : Emergency braking leh overload protection ang chi function te hi a sensitive a, a tangkai em tih test.
3. Thil hmanrua te dam rei theihna tur enkawlna point .
Hydraulic oil leh filter elements thlak danglam reng chuan system failure rate a tihhniam thei a ni. Darkar 2000 danah enkawl reng a tha. Open air-a hmanrua dahkhawmte tan chuan electrical circuit leh metal part-te rust venna lam ngaihtuah a ngai a ni. Operator training pawh a pawimawh hle. A hnathawh dan dik lo chuan pump pipe a block thei emaw, mixing shaft-a eccentric wear emaw a thlen thei.
Global Second-Hand concrete machinery transaction volume chu tunah hian a vaiin kum khat chhungin 7% zetin a pung a ni. Scientific purchase leh maintenance method thiam chuan hmanrua atanga investment return nasa takin a tichangtlung ang. Purchaser-te chuan third-party testing services te chu risk tihziaawmna turin an hmang tangkai a, chutih rual chuan Southeast Asia leh Africa ang chi market thara hmanraw tangkai tak tak, cost-demand trend chu ngaihven turin a rawt bawk.
