Rigging hte lifting gaw dai ni na aten na engineering bungli galaw ai hta ahkyak ai lam ni rai nga ai. Gawgap ai madang ni hpe gyin shalat nna hkan sa ai lam gaw bungli galaw ai lam hta shimlum lam, akyu rawng ai lam, bungli masing a hkamja lam hte hkrak matut mahkai nga ai. Ndai laika buk hta, rigging hte lifting gawgap ai lam a matu madang masa hpe, hpaji masa, bungli galaw ai ladat, shimlam ra kadawn ai lam ni, hparan hpareng ai lam hpe yu reng ai lam ngu ai ningmu mali kaw nna, hkrang shapraw ai hku sang lang dan da ai. Ndai laika buk gaw, hpaga lam hta galaw sa wa na matu hpaji ninghkring ni a lam matsun ni hpe jaw na matu yaw shada ai.
I. Hpaji masa hte madang masat masa ni
Rigging hte lifting a matu hpaji masa ni gaw gawgap ai madang ni a madung npawt nhpang rai nga ai. Mungkan ting na Crane galaw ai ni a hpung (IMCA) hte nye a mungdan a "Lifting Machinery a matu shimlam tara ni" (GB 6067.1-2010) a ra sharawng ai lam ni hte maren, rigging lata ai shaloi, sharawt nga ai lit a n-gun, hkrang, bungli galaw ai makau grup yin ni hte hkrak hkrak rai ra ai. Wire sumri shingkyit ni a daw garan ai atsam gaw, lit htaw ai hta na htam kru hta n yawm ra ai, synthetic fiber shingkyit ni a shimlam masa gaw sanit hta n yawm ra ai. Hook hte shackles zawn re ai matut mahkai ai arung arai ni gaw asan sha masat da ai load ratings ni nga ra nna, n jahten sharun ai chyam dinglik ai lam ni hpe ayan galaw ra ai.
Rigging hkrang shapraw ai lam hte seng nna, lagaw law law lang ai shingkyit ni a angle hpe 90℃laman hta hkang ra ai, grau law ai gaw 120℃hta n jan ra ai. N tara ai lit ni a matu, n-gun atsam a npawt nhpang hpe sawn la nna, karum shingtau ai lam hpe shingdaw ai jak ni hpe bang ra ai. Laksan bungli galaw ai masa (katsi ai shara hte n-gun ja ai makau grup yin zawn re ai) hta, ASTM A975 (sh) DNVGL-OS-E303 madang ni hte maren galaw ai laksan rigging arung arai ni hpe lang ra ai. Rigging arung arai yawng hpe, galaw shapraw ai wa a quality masat masa galaw ai laika ni hpe shawng nnan hkan nna, hkan tam lu na matu, laklai ai nambat ni hte masat da ra ai.
II. Madang masat da ai bungli galaw ladat ni
Standardized bungli galaw ladat ni gaw, gawgap ai lam hta shim lum lam hpe hkam la lu na matu ahkyak ai hkang zing ai shara ni rai nga ai. Dai hpe n galaw shi yang, "masum lang jep joi ai lam hte masum lang jep joi ai lam" galaw ra ai: rigging hpe myi hte mu lu ai n-gun n rawng ai hpe jep yu ra ai (cross-section n-gun n rawng ai hpe shawng na diameter a 10% jan ai hpe n-gun n rawng ai ngu sawn la ai), sharawt na masing a jahpan ni hpe jep joi yu ra ai, npawt nhpang hpe hkam sharang lu ai atsam (equa to1 than1) hpe jep yu ra ai. Lifting commander ni gaw laksan jak rung lang ai wa a masat da ai laika (Class Q1/Q2) hpe lang ra nna, masat da ai lata masat kumla ni (sh) ISO 7731 hta tsun da ai na lu ai hte mu lu ai masat kumla ni hpe lang ra ai.
Hkawm sa ai lam gaw "slow start, steady lift, steady positioning" ngu ai npawt tara hpe hkan sa ra ai. Dai lit hpe lamu ga kaw nna 0.3-0.5 metres tsaw ai shara kaw tawn da nna, ngang grin ai lam hpe yu na matu galaw ra ai. Crane law law hpe jawm galaw ai shaloi, synchronized control system hpe jung da ra ai, dai hku nna crane lapran na lit garan ai lam n bung ai lam gaw, masat da ai atsam hta na 8% hta jan na n re. Load hpe shara kaw tawn da ngut ai hpang, n hpaw shi yang, n yawm htum kaja ai pat shingdang ai jak lahkawng hpe shara kaw naw tawn da ra ai. Magam bungli galaw ai aten tup matut manoi yu reng ra ai, nbung laru a n-gun gaw madang 6 (10.8 m/s) hta jan wa yang bungli galaw ai lam hpe kalang ta jahkring kau ra ai.
III. Hkamja lam hpe hparan ai ladat
Rigging hte lifting bungli ni hta shimlam madang ni gaw ahkyak dik rai nga ai. OSHA 1926.1400 hte nye a mungdan a "Gawgap ai lam hta tsaw ai shara hta bungli galaw ai ni hpe shim lum hkra galaw na matu hpaji masa ni" (JGJ 80-2016) hte maren, bungli galaw ai shara hpe lahkawng lang shinggrup da ai (hard fencing + warning tape) hte makawp maga ra ai, ahkang n lu ai masha ni hpe dai shara hta n mai tawn da ai. Tinang hkum hpe makawp maga ai arung arai (PPE) ni hta hkrat sum ai hpe pat shingdang ai palawng, n-gun ja ai palawng (impact absorption capacity 200J hta grau kaba ai (sh) dai hte maren), hte n-gun n rawng ai lata magap (EN388 level 4 (sh) dai hta jan ai) ni lawm ra ai.
Arung arai ni hpe gram lajang ai lam gaw, shani shagu, bat shagu, shata shagu ngu ai masum lang na jep joi ai lam hpe galaw ai. Hpaji sawk sagawn ai lam ni hta, daw mat ai wire ni hpe jep joi ai lam (cross-lay wire sumri ni hpe lay length langai a kata daw mat ai wire yawng a 10% du yang, n-gun n rawng ai wire ni hpe yeng seng kau ra ai), matut mahkai ai lam ni a hkrang nsam galai shai ai lam (10% jan ovality nga ai shackles ni hpe pat hkum da ai), hte brake exbraliability hpe pat hkum da ai). jep joi ra ai). Hkyak hkyak masing ni hta, lit n-gun yawm mat na matu buffer zone (buffer material compressive strength 20 MPa hta grau ai (sh) dai hte maren) hte hkala nba hkrum ai ni hpe shawng nnan garum shingtau ai lam ni hpe (ja hkye mawai aten hpe minit 5 daram sha tawn da ai) ni hpe bang ra ai.
IV. Quality hpe hkang zing ai lam hte yu reng ai lam
Kaja ai yu reng ai ladat gaw madang ni hpe hkan sa na matu madi shadaw ya ai. Gawgap ai company ni gaw ISO 9001 quality management system hpe gawgap nna, rigging prat hkrun lam a jahpan ni hpe tup hkrak hkan sa ra ai (dai hta mari ai hte hkap la ai jahpan ni, aten kadun laman jep joi ai lam ni a jahpan ni, gram lajang ai labau ni lawm ai). Masum ngu na-hpung jep joi hpung ni gaw, GB/T 20118-2017 hte maren, shata kru shagu magnetic particle jep joi (sh) ultrasonic chyam dinglik ai lam galaw ra ai, n law htum 100% jep joi ai lam hpe shinggrup da ra ai.
Supervision unit ni gaw, gawgap masing hta lawm ai lit jahpan ni hpe bai maram yu na matu (mying jahpan bang da ai structural engineer langai mi lata mara nna madi shadaw da ai), laksan shimlam hpaji masa hpe tsun dan ai laika ni hpe (shanglawm ai ni yawng hkum tsup hkra lata mara da ai), shani shagu na bungli jahpan ni hpe bai maram yu na matu myit maju jung ra ai. Ton 100 jan n-gun jat ai bungli kaba ni a matu, npawt nhpang tsi lajang ai lam, rigging lata ai lam a shingdu labau, lawan ladan galaw ra ai lam ni hpe hkum tsup hkra galaw na matu hpaji ninghkring ni a bai maram dinglik zuphpawng ni hpe galaw ra ai. Asuya tara upadi hkan sa ai wuhpung ni gaw, IoT hpaji masa hpe jai lang nna, RFID tags hte rigging jak ni hpe hparan na matu, jak ni a masa hpe tengman ai-ten hta yu reng lu na matu galaw ra ai.
Rigging hte lifting gawgap ai madang ni hpe ngang ngang kang kang hkan sa ai gaw gawgap ai shimlam a matu ahkyak ai npawt nhpang rai nga ai. Hpaji masa ni hpe gram lajang ai, bungli galaw ai ladat ni hpe gram lajang ai, shimlam hpe hkrang shapraw ai hku galaw ai, hpaji rawng ai hku nna hkamja lam hpe yu reng ai hku nna, bungli galaw ai hta byin wa chye ai tsin-yam ni hpe grai shayawm lu nna, gawgap ai lam hta kam hpa mai ai lam hpe grau kaja hkra galaw lu na re. Hpaga lam hta shang lawm ai ni yawng gaw, mungkan madang ni hpe gram lajang ai lam ni hpe matut manoi yu reng ra ai (ISO 4309:2017, "Crane Wire Rope hpe yu lajang ai lam hte gram lajang ai lam a matu lam matsun ni" zawn re ai ni) hte digital hpaji masa ni hpe (BIM sharawt ai simulation hte hpaji rawng ai sensor monitoringf zawn re ai ni hpe) bang nna, n-gun rawng ai asak hkrung lam hte bungli galaw ai lam ni hpe rawt jat galu kaba wa hkra galaw ra ai. Standard ra kadawn ai lam ni hpe bungli galaw masha yawng myit dum ai hku galaw sa wa na matu ga gale ya ai hku nna sha, "zero accidents" ngu ai jahtum na yaw shada lam hpe lu la na re.
