(3) ukuphakamisa ukusetyenziswa kwekhonkco elijikelezayo
a.ubunzima bomthwalo buyalingana okanye bunganeno kunokuphakamisa isilingi sobukhulu.WLL.
b.xa usebenzisa i-2-leg okanye i-multi leg chain chain sling, i-angle enkulu yemilenze yesilingi, umthwalo omncinci onokuwuphakamisa;imilenze i-engile iyakuba ngaphantsi kwe-120° kuyo nayiphi na imeko (okt, i-angle yomlenze wetsheyini ene-engile yokukhokela ethe nkqo iya kuba ngaphantsi kwama-60°).
c.xa uphakamisa i-choker hitch, umthwalo uya kuba ngaphantsi kwe-80% WLL.
d.Ikhonkco lokuphakamisa liya kuba lithe tye ngaphandle kokukrazula, ukugquma okanye ukugoba.Zama ukuphepha izinto ezinzima eziqengqelekayo kwitsheyini.
(1) ukuhlolwa kwemihla ngemihla
a.Umhloli, amaxesha amaninzi kunye neerekhodi
Umsebenzisi okanye abasebenzi abachongiweyo baya kuqhuba uhlolo lwenkangeleko yesiqhelo kwitsheyini yokuphakamisa yonke imihla yokusebenza, kwaye kuya kubakho irekhodi "yohlobo lokuhlola indawo yesilingi yemihla ngemihla" (jonga kwiSihlomelo) kwisiza, ebonisa ukuba isilingi sinokusetyenziswa ngokuqhelekileyo.
b.Ukuhlolwa okubonakalayo
Jonga ngokubonakalayo inkangeleko yeempawu zokunxiba, ukuguqulwa okanye umonakalo wangaphandle.Ukuba iziphene zifunyenwe ekuhlolweni, qinisekisa ukuba zingasetyenziswa kwakhona ngokwendlela yokuhlola rhoqo.
(2) Ukuhlolwa kwamaxesha athile
a.Umhloli, amaxesha amaninzi kunye neerekhodi
Abasebenzi abachongiweyo baya kuqhuba uhlolo olubanzi kwikhonkco ngokuhambelana neempawu zesiphene ezicetywayo ngokuhlolwa rhoqo, kwaye benze iirekhodi zokuvavanya ukuba ikhonkco lingaqhubeka lisetyenziswa.
b.Jonga amanqaku
i）Ukuba amanqaku angaphandle afana namanqaku okuphakamisa ikhonkco kunye nomthwalo wokugqibela wokusebenza acacile;
ii) Iziqhagamshelo eziphezulu kunye nezisezantsi (ikhonkco eliphambili, ikhonkco eliphakathi, iziqhagamshelo kunye neehaki) zekhonkco lokuphakamisa zikhubazekile, zinqunywe kwaye ziqhekeke, ezidlula iimfuno ezisemgangathweni kwaye azikwazi ukusetyenziswa;
iii) Ukuguqulwa kwekhonkco lekhonkco: ikhonkco lekhonkco lijikiwe, ligobile kwaye lide, kwaye alinakusetyenziswa xa lidlula iimfuno ezisemgangathweni;
iv) Ukunxitywa kwekhonkco: inotshi, inotshi, igouge kunye nokunxitywa kwekhonkco elingaphandle kwecandelo elithe tye alinakusetyenziswa xa lingaphaya kweemfuno eziqhelekileyo;
v) I-Hook deformation: "ukuvula" ukuguqulwa kunye nokuphazamiseka kokuvuleka kwe-huku kugqithise iimfuno ezisemgangathweni kwaye akunakusetyenziswa;
vi) Iintanda: iintanda ezingqinwe ngokujongwa okubonakalayo okanye i-NDT ayinakusetyenziswa.
a.ukuguqulwa:
ubude bobude obungaphandle＞3％
ubude bangaphakathi bobude＞5％
b.ukunxiba:
Idayamitha yecandelo lomnqamlezo wekhonkco emva kokunxiba ayisayi kuba ngaphantsi nge-10% (okt, idayamitha <90% yesiqhelo)
c.iintanda:
Akukho ukuqhekeka kuvunyelwe kumphezulu wekhonkco lekhonkco ngokuhlola okubonakalayo okanye ukuhlolwa kwezixhobo.
d.ukugoba okanye ukuphazamiseka:
Akukho ukugoba okucacileyo okanye ukuphazamiseka, ukubola okunzulu okanye ukuqhotyoshela okungenakususwa kuvunyelwe kwikhonkco lekhonkco.
