Dai ni na aten na hpaga lam hte engineering gawgap ai lam hta, rigging hte lifting gaw, arung arai ni hpe hparan ai hte jak rung ni hpe jung ai hta madung daw ni rai nga ai. Shanhte a shim lum lam hte kam hpa mai ai lam gaw, arung arai ni hpe atsawm sha lata la ai hta hkrak madung nga ai. Rigging arung arai ni gaw static load-bearing ra kadawn ai lam ni hpe hkan sa ra ai sha n-ga, dynamic loads, grup yin shingra tara hpe hkra machyi shangun ai, aten galu-n-gun yawm mat ai zawn re ai mayak mahkak law law hpe mung hkam sharang lu ra ai. Dai majaw, rigging hte lifting materials ni a matu lata la ai lam hte hpaji masa ni hpe-sung sung hkaja ai lam gaw, bungli galaw ai lam hta shim lum lam hpe hkam la lu na matu hte sut masa lam hpe grau kaja hkra galaw lu na matu ahkyak nga ai.
I. Rigging galaw na matu ra kadawn ai madung bungli galaw ai lam ni
Rigging hte lifting arung arai ni hpe lata ai shaloi, bungli galaw ai lam hpe madun ai lam law law hpe atsawm sha myit yu ra ai. N-gun gaw ahkyak dik htum rai nna, tensile n-gun hte yield n-gun lahkawng yan hpe shinggrup da ai, dai gaw rigging a jahtum na lit-hkap la lu ai atsam hpe hkrak sha hkra machyi shangun ai. Ga shadawn, wire rope rigging hpe laksan hku nna, -madang tsaw ai carbon steel (sh) alloy steel hte galaw ai rai nna, 1770 MPa kaw nna 2160 MPa du hkra n-gun rawng ai majaw, n-gun kaba ai sharawt ai lam hta ra kadawn ai lam ni hpe hkap la lu ai. Toughness mung ahkyak ai, grau nna hkra machyi ai npu hta, brittle fracture n byin hkra, dai arai gaw ductility kaja hpe madun dan ra ai. Dai hta n-ga, n-gun n rawng ai lam gaw, bai kahtap nna shingjawng ai npu hta rigging a ngang grin ai lam hpe dawdan ya nna, n-gun n rawng ai lam gaw, hka lim ai, hka lim ai, shing nrai, tsi mawan ni lawm ai shara ni hta shi a magam bungli prat hpe hkrak hkra hkra machyi shangun ai.
II. Madung Rigging arung arai ni a hpaji masa hte jai lang ai lam ni
1. Metal Materials: Htunghking hte Hpaji ningnan lapran hta rap ra ai lam
Metal materials gaw rigging hpaga lam hta madung lata la ai lam rai nna, steel wire rope gaw n-gun kaba ai, n-gun ja ai, sakse hkam da ai galaw shapraw ai ladat ni a majaw uphkang nga ai. Galvanized steel wire rope, n-gun n-gun hpe ninghkap lu na matu ntsa lam hpe gram lajang ai hku nna grai jat wa ai, panglai hpaji hte hka lim ai shara ni hta jai lang na matu htuk manu ai. Stainless steel wire sumri (304/316 series zawn re ai) hpe acid hte alkali hpe grai hkam sharang lu ai majaw, tsi mawan hte malu masha galaw shapraw ai bungli ni hta grai lang ma ai.
Hpyen n-gang hte shingkyit zawn re ai n-gang ni hpe matut mahkai ai arung arai ni hpe alloy structural steel (40Cr hte 35CrMo zawn re ai) ni hte galaw chye ai. Heat-treated n-gun ja ai gaw n-gun ja ai hte n-gun yawm ai hpe ninghkap lu ai lahkawng yan hpe jaw ya ai. Kade nna ai aten hta, nickel-based alloys (Inconel zawn re ai) ni gaw, grai katsi ai hte n-gun ja ai makau grup yin ni hta ngang grin ai majaw, nbungli zawn re ai high-end application ni hta grau grau jai lang wa sai.
2. Synthetic Fibers: N-gun n law ai hte grup yin hpe n hkra ai masa ni
Hpaji masa rawt jat wa ai hte maren, n-gun n law ai, n-gun n rawng ai, n-gun n rawng ai, n-gun n rawng ai majaw, n-gun rawng ai n-gun rawng ai arung arai ni rai nga ai polyester (PET), polypropylene (PP), hte ultra-n-gun kaba ai polyethylene (UHMWPE) zawn re ai n-gun rawng ai n-gun rawng ai arung arai ni gaw, n-gun n rawng ai n-gun rawng ai arung arai ni tai wa sai. Ga shadawn, UHMWPE fibers (Dyneema® zawn re ai) ni gaw steel wire hta htam 15 jan n-gun ja nna, n-gun gaw langai-eighth sha n-gun rawng ai majaw, nbungli jak n-gang ni hpe jung ai zawn re ai hkrak tup galaw ai bungli ni hta grau nna akyu rawng ai. Raitim, shanhte a n-gun ja ai-hkum hkrang n-gun (100℃npu) hte UV hpe hkam sharang lu ai atsam gaw shanhte hpe jai lang ai lam hpe pat shingdang da ai majaw, coating hpaji masa hku nna gram lajang ra ai.
III. Arung arai lata ai hta dawdan lam ni
1. Load masa ni hpe bungli galaw ai masa ni hte bung hkra galaw ai
Rigging arung arai ni hpe bungli galaw ai masa hta hkrum katut ai load amyu ni hte hkrak hkrak hkan sa ra ai. Ga shadawn, n-gun ja ai lit ni (hpyen n-gun rawng ai (sh) sharawt ai shaloi hkrat sum ai zawn re ai) ni gaw, n-gun ja ai n-gun ra ai, pre-tensioned steel wire rope (sh) composite material ni hpe grau ra sharawng ai. Maga mi de, static loads ni gaw, manu jahpu-htuk manu ai arung arai ni hpe ahkyak shatai nna galaw lu ai, ga shadawn, n-gun n rawng ai n-gang n-gang sumri zawn re ai ni hpe.
2. grup yin hte htuk manu hkra galaw lu ai atsam
Corrosive makau grup yin (hka hkin gau ginra ni (sh) tsi rung ni zawn re ai ni) hta stainless steel (sh) coated makawp maga ai arung arai ni hpe ahkyak shatai nna galaw ma ai. N-gun ja ai-katsi ai shara (hpyen hpaga lam hta zawn) hta katsi ai hpe hkam sharang lu ai n-gang (Cr{3}}Mo alloys zawn re ai) shing nrai, ceramic fiber composite rigging ra ai.
3. Sut masa hte prat hkrun lam manu jahpu .
Hpa majaw nga yang, n-gun ja ai arung arai ni (nickel-based alloys (sh) UHMWPE zawn re ai) ni gaw, shawng nnan na manu grau law ai raitim, shanhte a prat galu ai hte gram lajang ra ai lam n law ai majaw, prat tup na manu hpe grai shayawm ya lu ai. Ga shadawn, stainless steel rigging gaw, n-gun n rawng ai makau grup yin hta, shinggyim masha ni lang ai carbon steel arai ni hta grau n law ai hku galai shai ra ai.
IV. Htawm hpang rawt jat galu kaba wa na matu lam matsun ni
Material science hta rawt jat galu kaba wa ai hte maren, rigging arung arai ni gaw, -magam bungli galaw lu ai composite ni hte hpaji rawng ai hpaji masa ni de rawt jat wa nga ai. Ga shadawn, carbon fiber hte n-gun ja ai polymer (CFRP) rigging gaw ultra-n-gun kaba ai hte n-gun n-ja ai atsam ni hpe kayau kaya galaw ai majaw, lamu ga ntsa na sanghpaw li hpe sharawt na matu htuk manu ai. Sensor ni hte bang da ai Smart rigging gaw, myit ru myit tsang lam hte n-gun yawm ai lam hpe aten dep yu lu nna, shim lum lam hpe grau nna jat wa shangun ai.
Arung arai ni hpe sharawt na matu rigging arung arai lata ai lam gaw, jak hpaji, arung arai hpaji, engineering galaw ai lam ni lawm ai hkrang shapraw dawdan ai lam re. Practice galaw ai ni gaw bungli galaw ai lam hpe madun ai masat kumla ni, bungli galaw ai masa ni, sut masa lam ni hpe tsep kawp myit yu ra ai, hpaji masa hku lata la ai hku nna shimlum lam hte akyu rawng ai lam lapran hta kaja dik ai rap ra lam hpe lu la na matu ra ai. Htawm hpang de, arung arai hpaji ningnan ni hpe bai gram lajang ai hte, rigging arung arai ni gaw, sharawt ai bungli ni hpe grau tsaw ai madang de rawt jat wa hkra grau nna karum ya na re.
