Ithebula 2: Inkomba ye-WLL
(2)isihlilingi seketangoizinhlobo kanye nemilenze angle
a. indwayimane yeketango lomlenze owodwa
b. Isilingi seketanga lemilenze emi-2
c. Isilingi seketanga lemilenze emi-3
d. 4-leg chain isilingi
(3) ukuphakamisa ukusetshenziswa kweketango eliyindilinga
a. isisindo somthwalo sizolingana noma sibe ngaphansi kunesihlilingi sokuphakamisa iketango. WLL.
b. uma usebenzisa isihlilingi sochungechunge lwemilenze emi-2 noma eminingi, i-engeli enkulu yemilenze ye-sling, umthwalo omncane ongawuphakamisa; I-engeli yemilenze izoba ngaphansi kuka-120° kunoma yikuphi (okungukuthi, i-engeli yomlenze weketango ene-engeli yokuhola eqondile izoba ngaphansi kuka-60°).
c. lapho uphakamisa i-choker hitch, umthwalo uzoba ngaphansi kwama-80% WLL.
d. Iketango eliphakamisayo kufanele liqonde ngaphandle kokugoqa, ukugoqa noma ukugoba. Zama ukugwema izinto ezisindayo ezigingqa iketango.
(1) ukuhlolwa kwansuku zonke
a. Umhloli, imvamisa namarekhodi
Umsebenzisi noma izisebenzi eziqokiwe zizohlola ukubukeka okujwayelekile ochungechungeni oluphakamisayo zonke izinsuku zokusebenza, futhi kuzoba nerekhodi "lendlela yokuhlola indawo yansuku zonke yesihlilingi" (bona Isijobelelo) esizeni, elibonisa ukuthi isihlilingi singasetshenziswa ngendlela evamile.
b. Ukuhlola okubonakalayo
Bheka ngokubukeka ukubukeka kwezimpawu zokuguga okukhulu, ukuwohloka noma ukulimala kwangaphandle. Uma kutholakala amaphutha ekuhlolweni, qinisekisa ukuthi angasetshenziswa futhi ngokwendlela yokuhlola evamile.
(2) Ukuhlolwa ngezikhathi ezithile
a. Umhloli, imvamisa namarekhodi
Abasebenzi abaqokiwe bazohlola ngokucophelela iketango ngokwezimpawu zokukhubazeka eziphakanyiswe ukuhlola okuvamile, futhi benze amarekhodi ukuze bahlole ukuthi iketango lingaqhubeka yini lisetshenziswa.
b. Hlola amaphuzu
i）Ukuthi amamaki angaphandle afana neketango lokuphakamisa uphawu kanye nomthwalo wokugcina wokusebenza acacile yini;
ii) Izixhumi ezingenhla nezingezansi (isixhumanisi esiyinhloko, isixhumanisi esimaphakathi, izixhumi namahhuku) zeketango eliphakamisayo zikhubazekile, ziyasikwa futhi ziyaqhekeka, ezeqa izidingo ezijwayelekile futhi azikwazi ukusetshenziswa;
iii) Ukuguqulwa kwe-chain link: iketango ilinki lisontekile, ligobile futhi lenziwe side, futhi ngeke lisetshenziswe uma lidlula izidingo ezijwayelekile;
iv) Ukugqokwa kwesixhumanisi: inothi, inothi, i-gouge nokuguga kwesixhumanisi ngaphandle kwengxenye eqondile ngeke isetshenziswe uma yeqa izimfuneko ezijwayelekile;
v) I-Hook deformation: ukuguqulwa "okuvula" nokuhlanekezela ukuvuleka kwehhuku kudlula izidingo ezijwayelekile futhi akunakusetshenziswa;
vi) Imifantu: imifantu efakazelwe ngokubheka okubonakalayo noma i-NDT ayikwazi ukusetshenziswa.
a. ukuguqulwa:
ubude bangaphandle＞3％
ubude bangaphakathi＞5％
b. ukugqoka:
isixhumanisi ububanzi besigaba esiphambene ngemva kokugqoka akufanele sibe ngaphansi ngo-10% (okungukuthi, ububanzi obungu-< 90% ngokwegama)
c. imifantu:
Akukho ukuqhekeka okuvunyelwe phezu kwesixhumanisi seketango ngokuhlola okubonwayo noma ukuhlolwa kwemishini.
d. ukugoba noma ukuhlanekezela:
Akukho ukugoba okusobala noma ukuhlanekezela, ukugqwala okukhulu noma okunamathiselwe okungenakususwa okuvunyelwe kusixhumanisi seketango.
(2) ihuku
a. Ukuvulwa kwehuku: ukwanda kosayizi wokuvula ihhuku akumele kudlule u-10% yenani elilinganiselwe.
b. Ukugqoka kwesigaba esicindezelekile (okuyingozi): ubukhulu besigaba endaweni yokugqoka akufanele buncishiswe ngaphezu kuka-5%
c. Ukusonta kwe-twist: ukuguqulwa kwe-twist yomzimba we-hook akufanele kudlule i-5%.
d. Imifantu: imifantu ayivunyelwe kuyo yonke indawo yehhuku ngokuhlola okubonwayo noma ukuhlolwa kwemishini.
e. Ama-Nick and gouges: angalungiswa ngokugaya noma ukufaka. Indawo elungisiwe kanye nezindawo eziseduze zizoshintsha ngokushelela ngaphandle kwezinguquko eziphuthumayo esigabeni. Ubukhulu bengxenye epholishiwe akufanele buncishiswe ngaphezu kuka-5%.
(3) isixhumanisi esiyinhloko
a. Ukuhlanekezela: ukuhlanekezela kwesixhumanisi esiyinhloko akufanele kudlule u-5%.
b. Gqoka: ukuguga kwendawo yesixhumanisi esiyinhloko akufanele kudlule u-10% wobubanzi bokuqala
c. Imifantu: imifantu ayivunyelwe kuyo yonke isixhumanisi esiyinhloko ngokuhlola okubonakalayo noma ukuhlolwa kwemishini.
(4) amaketanga nezinye izesekeli
a. Ukuvula: usayizi wokuvula we-shackle udlula u-10% yenani lokuqala.
b. Gqoka: ububanzi bephini noma iphinikhodi kugqokwe ngaphezu kwe-10% yobubanzi bokuqala; ukugqokwa kwesigaba esicindezelekile (okuyingozi) kungaphezu kuka-5%
c. Ukuqhekeka: akukho ukuqhekeka okuvunyelwe kuyo yonke into engaphezulu ngokuhlola okubonwayo noma ukuhlola okokusebenza.
(1) Izixhumanisi zamaketanga ajwayelekile
(2) Ihuku elikhubazekile (elilahliwe)
(3) Ukuguquguquka, ukuguga kanye nokuqhekeka kwezixhumanisi zamaketango (ukukrweleka)
(4) Ukugqokwa kwendawo ebusweni besixhumanisi seketango (kungalungiswa)
(5) I-chain link igugile kancane futhi ikhubazekile (ingaqhubeka nokusetshenziswa)
