Engineering machinery lamah chuan second-kut excavator te hi khawvel pum huapa construction leh mining market-a hmanraw thlan pawimawh tak an ni ta a, hei hi an man to lutuk-Effectiveness leh strong practicality vang a ni. An structural composition leh performance characteristics hriatthiamna hian a lei duhtute chu thutlukna dik zawk siam turin a pui ang. He article hian second-hand excavators core structure chu technical lam atanga thlirin a zirchiang ang a, international market-a an value performance a zirchiang ang.
Core structural composition 1000 a ni.
Second-hand excavator structure-ah hian a bik takin part pali a awm a, chungte chu power system, hydraulic system, working device leh chassis te an ni.
Power system hi excavator "thinlung" a ni a, a tlangpuiin diesel engine Cummins, Isuzu leh brand dangte an hmang thin. Engine chakna hian hmanrua hnathawh dan a nghawng nghal a, second-kut hmanrua engine dinhmun pawh ngaihven a ngai a, chutah chuan a chhe lam degree, maintenance record leh emission standard-te chu tualchhung dan zawm a nih leh nih loh te pawh a tel a ni.
Hydraulic system hi excavator "nerve" a ni a, boom, dipper leh bucket movement control hna a thawk a ni. High-Quality hydraulic pump, valve group leh cylinder te hian hmanrua hman dan dik leh nghet tak a siam thei a ni. Second-hand excavator-a hydraulic system-ah chuan leak, pressure tling lo emaw, components tar emaw a awm leh awm loh enfiah a ngai a ni.
Working device-ah hian boom, dipper leh bucket te a tel a, chu chuan excavator hnathawh theihna chu direct-in a tichiang a ni. Excavator model hrang hrangah bucket tonnage hrang hrang dah a ni a, hnathawhna hmun hrang hrang, leilung hnathawh, ore emaw construction waste emaw atan a tha hle. Second-kut hmanrua hnathawh dan chu a chhe leh a chhe tawh loh enfiah a ngai a, a bik takin bucket edge-a sharpness leh structural integrity te hi endik a ngai a ni.
Chassis hi crawler track emaw tire emaw a ni a, supporting wheel leh guide wheels a awm a, hei hian hmanrua stability leh mobility a nghawng nghal vek a ni. Crawler excavator te hi complex terrain atan a tha a, tire-type excavator te hi kawngpui siamna atan a tha zawk bawk. Second-kut hmanrua chassis chu track tension a awm leh awm loh enfiah a ngai a, wheel wear leh drive motor performance a support bawk.
Market value leh lei dan tur rawtna .
Second-hand excavator man hi a tlangpuiin a thar man atanga 30%-70% a ni a, kum, hnathawh hun leh enkawlna dinhmun a zirin a ni. International market-ah chuan Japan leh European leh American brand atanga second-hand excavator te hi an rintlak em em avangin an duhsak hle a ni. A lei dawnin hmanrua enkawlna record, engine leh hydraulic system dinhmun enfiah a, professional testing hmanga a dam chhung la awm chu endik a tha.
Khawvel pum huapa infrastructure sakna tur mamawhna a san chhoh zel chuan a pahnihna-Hand Excavator market chu a thawk chhunzawm zel dawn a ni. A structural characteristics leh market dynamics hriatthiamna hian a lei duhtute chu a man tlawm zawka hmanraw tangkai tak tak an hmuh theih nan leh engineering project-te economic lama hlawkna an hmuh theih nan a pui dawn a ni.
