Ithebula 2: Inkomba ye-WLL
(2)i-chain slingizinhlobo kanye ne-angle yemilenze
a. isilingi somlenze owodwa
b. isilingi esinemilenze emibili
c. isilingi sezintambo ezintathu
d. i-sling yezintambo ezine
(3) ukusetshenziswa kweketanga lesixhumanisi eliyindilinga
a. Isisindo somthwalo kufanele silingane noma sibe ngaphansi kunesisindo esiphezulu se-lifting chain sling. WLL.
b. uma usebenzisa i-sling enemilenze emibili noma eminingi, i-engeli enkulu yemilenze ye-sling, umthwalo omncane ongayiphakamisa; i-engeli yemilenze kufanele ibe ngaphansi kuka-120° kunoma yikuphi (okungukuthi, i-engeli yemilenze yeketanga ene-engeli yokuhola eqondile kufanele ibe ngaphansi kuka-60°).
c. uma uphakamisa i-choker hitch, umthwalo kufanele ube ngaphansi kuka-80% WLL.
d. Iketanga lokuphakamisa kufanele liqonde ngaphandle kokugoba, ukufiphaza noma ukugoba. Zama ukugwema izinto ezisindayo ezigingqika eketanga.
(1) ukuhlolwa kwansuku zonke
a. Umhloli, izikhathi kanye namarekhodi
Umqhubi noma abasebenzi abaqokiwe kufanele benze ukuhlolwa kokubonakala okuvamile eketangeni lokuphakamisa nsuku zonke zokusebenza, futhi kuzoba nerekhodi "lohlobo lokuhlolwa kwamaphuzu nsuku zonke kwe-sling" (bheka i-Annex) endaweni, okubonisa ukuthi i-sling ingasetshenziswa ngokujwayelekile.
b. Ukuhlola okubonakalayo
Hlola ngokubuka ukubukeka kwezimpawu zokuguguleka okukhulu, ukuguquka noma umonakalo wangaphandle. Uma kutholakala amaphutha ekuhlolweni, qinisekisa ukuthi ingasetshenziswa futhi ngokwendlela yokuhlola evamile.
(2) Ukuhlolwa okwenziwa ngezikhathi ezithile
a. Umhloli, izikhathi kanye namarekhodi
Abasebenzi abaqokiwe kumele benze ukuhlolwa okuphelele kweketanga ngokwezimpawu zokukhubazeka eziphakanyiswe ukuhlolwa okuvamile, futhi benze amarekhodi okuhlola ukuthi ngabe iketanga lingaqhubeka yini nokusetshenziswa.
b. Amaphuzu okuhlola
i） Ukuthi izimpawu zangaphandle ezifana nophawu lokuphakamisa uchungechunge kanye nomthwalo wokugcina wokusebenza zicacile yini;
ii) Izixhumi ezingenhla nezingezansi (isixhumanisi esikhulu, isixhumanisi esiphakathi, izixhumi kanye nama-hook) zeketanga lokuphakamisa ziyaguquguquka, ziyasikwa futhi ziyaqhekeka, ezidlula izidingo ezijwayelekile futhi azikwazi ukusetshenziswa;
iii) Ukuguqulwa kwesixhumanisi seketanga: isixhumanisi seketanga sisontekile, sigobile futhi sinwetshiwe, futhi asinakusetshenziswa uma sidlula izidingo ezijwayelekile;
iv) Ukuguga kwezixhumanisi: i-notch, i-notch, i-gouge kanye nokuguga kwesixhumanisi esingaphandle kwesigaba esiqondile akukwazi ukusetshenziswa uma kudlula izidingo ezijwayelekile;
v) Ukuguqulwa kwehokhi: ukuguqulwa "kokuvula" kanye nokuphambuka kokuvuleka kwehokhi kudlula izidingo ezijwayelekile futhi akukwazi ukusetshenziswa;
vi) Imifantu: imifantu efakazelwe ngokubuka ngamehlo noma i-NDT ayikwazi ukusetshenziswa.
a. ukuguqulwa:
ubude obungaphandle > 3%
ubude obungaphakathi > 5%
b. ukugqoka:
ububanzi besigaba esiphambene ngemuva kokugqoka akufanele bube ngaphansi kuka-10% (okungukuthi, ububanzi < 90% okujwayelekile)
c. imifantu:
Akukho ukuqhekeka okuvunyelwe ebusweni besixhumanisi seketanga ngokuhlola okubonakalayo noma ukuhlolwa kwemishini.
d. ukugoba noma ukuhlanekezela:
Akukho ukugoba noma ukuphambuka okusobala, ukugqwala okukhulu noma ukunamathela okungenakususwa okuvunyelwe kwisixhumanisi seketanga.
(2) i-hook
a. Ukuvulwa kwe-hook: ukwanda kosayizi wokuvulwa kwe-hook akumele kudlule u-10% wenani elilinganiselwe.
b. Ukuguga kwesigaba esicindezelekile (esiyingozi): ubukhulu besigaba endaweni yokuguga akufanele buncishiswe ngaphezu kuka-5%
c. Ukuguquguquka kokusonta: ukuguqulwa kokusonta komzimba we-hook akumele kudlule u-5%.
d. Imifantu: imifantu ayivunyelwe ebusweni bonke behhuku ngokuhlola okubonakalayo noma ukuhlolwa kwemishini.
e. Ama-Nick nama-gouges: angalungiswa ngokugaya noma ngokufaka amafayili. Indawo elungisiwe kanye nezindawo eziseduze kufanele zishintshe kahle ngaphandle kokushintsha okungazelelwe engxenyeni. Ubukhulu bengxenye epholishiwe akufanele buncishiswe ngaphezu kuka-5%.
(3) isixhumanisi esiyinhloko
a. Ukuhlanekezela: ukuhlanekezela kwesixhumanisi esiyinhloko sonke akumele kudlule u-5%.
b. Ukuguguleka: ukuguguleka kobuso besixhumanisi esikhulu akumele kudlule u-10% wobubanzi bokuqala
c. Imifantu: imifantu ayivunyelwe kuyo yonke indawo eyinhloko yokuxhumanisa ngokuhlola okubonakalayo noma ukuhlolwa kwemishini.
(4) izikhonkwane nezinye izesekeli
a. Ukuvulwa: usayizi wokuvulwa kwe-shackle udlula u-10% wenani lokuqala.
b. Ukuguguleka: ububanzi bephini noma iphini shaft buguguleka ngaphezu kuka-10% wobubanzi bokuqala; ukuguguleka kwesigaba esicindezelwe (esiyingozi) kungaphezu kuka-5%
c. Uqhekeko: akukho ukuqhekeka okuvunyelwe kuyo yonke indawo yokwengeza ngokuhlola okubonakalayo noma ukuhlolwa kwemishini.
(1) Izixhumanisi zeketanga ezijwayelekile
(2) Ihhuku eliguquliwe (eliklwejiwe)
(3) Ukuguqulwa, ukuguguleka kanye nokuqhekeka kwezixhumanisi zamaketanga (ukuklwebha)
(4) Ukuguga kwendawo ebusweni besixhumanisi seketanga (kungalungiswa)
(5) Isixhumanisi seketanga sigugile kancane futhi sikhubazekile (singaqhubeka sisetshenziswa)
