Iyini Isici Sokuphepha esingu-7:1 futhi Kungani Ibalulekile?

Umphathi wokukhwabanisa ukhetha a ukuphakamisa isihlilingi  kulinganiselwe amathani ama-2. Umthwalo unesisindo esingamathani angu-1.5—ungaphakathi komkhawulo. Kodwa kwenzekani uma indwayimane igcwele ukushaqeka? Kuthiwani uma umthwalo ungahlulelwanga kahle? Kuthiwani uma ukucekelwa phansi kwemvelo kuye kwenza imicu ibe buthaka? Isilingi esinezinto zokuphepha ezingu-7:1 sinikeza isigcinalwazi esibalulekile kulezi zimo ezingalindelekile.

 

I-Lishenflex  isineminyaka engaphezu kwamashumi amabili ikhiqiza izihlilingi eziphakamisa izinto zokwenziwa, futhi umbuzo owodwa esiwuzwa kakhulu kubasebenzisi bokugcina uthi: Isho ukuthini leyo nombolo engu-7:1 kumaka? Impendulo ibalulekile ekuqinisweni okuphephile—futhi ngokuvamile ayiqondwa kahle.

 

Isici Sokuphepha vs. Umkhawulo Womthwalo Osebenzayo: Ukuqonda Umehluko

Ukuze uqonde isici sokuphepha esingu-7:1, okokuqala udinga ukuhlukanisa phakathi kwamatemu amabili abalulekile: Umkhawulo Womthwalo Osebenzayo (WLL) kanye Nokuqina Kokuphuka  (okubuye kubizwe ngokuthi I-Minimum Breaking Load noma i-MBL) .

 

Ngokusho kwe- Hercules Lifting guide , ubudlelwano phakathi kwalawa manani amabili kunqunywa isici sokuklama: WLL = Amandla Aphula ÷ I-Design Factor .

 

Isici sokuphepha esingu -7:1  sisho ukuthi amandla okuphuka kwesihlilingi aphindwe kasikhombisa i-WLL yayo. Ngesihlilingi se-WLL esiyithani eli-1, amandla okuphuka okungenani amathani ayi-7. Njengoba kuchazwe ezindinganisweni zemboni kuhlanganise I-EN 1492-1 kanye ne-EN 1492-2 , lesi silinganiso siyimfuneko encane yezihlilingi zokwenziwa.

Kungani 7:1 for Synthetic Lifting Slings?

Izinhlobo zemishini ehlukene zisebenzisa izici ezihlukene zokuphepha :

 

Izilingi zefiber zokwenziwa zidinga isici sokuphepha esiphezulu kunentambo yocingo noma iketango ngoba zisengozini kakhulu ezintweni zemvelo ezingehlisa amandla ngaphandle kwesixwayiso esibonakalayo.

 

Ngokusho kwe -WorkSafe WA's Mines Safety Bulletin No. 155 , izihlilingi eziyindilinga zokwenziwa zisengozini enkulu yokulimala ngokomzimba, ukukhanya kwelanga (i-ultraviolet), amakhemikhali, nokushisa okudlulele kunezinye izinhlobo zamagiya okuphakamisa. Isici esingu-7:1 sinikeza isivimbeli ngokumelene nalezi zimo zomhlaba wangempela ezingalindelekile.

 

Njengoba i-Lifting Gear Direct  iphawula ekuqondisweni komkhiqizo wabo, izinguquko zakamuva zezimboni ziye zadinga izinhlobo ezithile zokuphakamisa izihlilingi ukuze zibe nesici sokuphepha esingu-7:1 kunesilinganiso esidala esingu-5:1—okusho ukuthi izihlilingi manje zinomthwalo omncane wokuphuka ophindwe kasikhombisa i-WLL yazo.

 

Inani Lomhlaba Wangempela Lesici Sokuphepha esingu-7:1

Isici esingu-7:1 asiyona into engafanele. Ibala:

 

Ukulayisha okushaqisayo - ukulayisha ngokuzumayo noma ukukhululwa

 

Ukunyakaza okunamandla - ukushwibeka noma ukugudluka ngesikhathi sokuphakanyiswa

 

Ukucekelwa phansi kwemvelo —Ukulimala kwe-UV, amakhemikhali, noma ukushisa ngokuhamba kwesikhathi

 

Ukuguga —ukuhuzuka, ukusikeka, nokulimala onqenqemeni

 

Ama-engeli -ukunciphisa ikhono lokuklinywa noma ukushaywa kukabhasikidi

 

Ukubekezelelana kokukhiqiza - ukuhlukahluka kwempahla nokwakhiwa

 

Ngokusho kwe-CERTEX Denmark , izihlilingi zendwangu zokwenziwa zisengozini ikakhulukazi emiphethweni ebukhali, ukuguga nokungqubuzana, ukusikeka nezinyembezi, ukushisa okungaphezu kwezinga lokushisa elivunyelwe, amakhemikhali angahambelani, kanye nokuchayeka kwe-UV ngokuhamba kwesikhathi. Isici sokuphepha esingu-7:1 sinikeza umkhawulo walobu buthakathaka, iqinisekisa ukuthi isihlilingi esonakaliswe umonakalo omncane wendawo ezungezile singase sibe namandla ayinsalela anele okusingatha umthwalo waso olinganiselwe ngokuphepha.

 

Ukuhlolwa kwelebhu ye- Lishenflex kuqinisekisa ukuthi ngisho nokusikwa konqenqema okungu-10%—okungase kuphuthelwe ukuhlola ngokushesha ukusetshenziswa kwangaphambi kokusetshenziswa—kungehlisa umthamo we-sling ngo-35%. Isici esingu-7:1 siqinisekisa ukuthi isihlilingi esinomonakalo omncane singase sigcine amandla anele ukuphakamisa umthwalo wayo olinganiselwe. Yingakho isici sokuphepha esiphezulu singesona nje isidingo sokuthobela—kuyisidingo esingokoqobo.

 

Indlela Isici Sokuphepha 7:1 Sivela Ngayo Ngokusebenza

Ngaphansi kwe-EN 1492-1 ne-EN 1492-2, isici sokuphepha esingu-7:1 sihlanganiswa nezimpawu zomthamo ezinamakhodi anombala :

 

Umthombo: EN 1492-1/2 amazinga ekhodi yombala

 

I-DIN EN 1492-2  ithi izihlilingi eziyindilinga kufanele zibe nesici sokuphepha esiphezulu esingu-7:1, okusho ukuthi i-WLL engu-1000 kg ihambisana nomthwalo wekhefu ongu-7000 kg. Ukucaciswa komkhiqizo we-SpanSet kuqinisekisa ukuthi izihlilingi zabo zewebhu eziyisicaba zakhiwe ngento yokuphepha engu-7:1, umkhiqizo ngamunye unikezwe isitifiketi sokuhambisana kanye nenombolo ye-serial ehlukile ukuze kulandeleke .

 

Amazinga Agunyaza 7:1

Isici sokuphepha esingu-7:1 sigunyazwe amazinga amaningi wamazwe ngamazwe wezihlilingi zokwenziwa:

 

I-WorkSafe WA  iqinisekisa ukuthi kuzihlilingi eziyindilinga ze-polyester ezithobelana ne-AS 4497:2018, umthamo omncane wokuphuka uphindwe kasikhombisa i-WLL yazo , futhi ngayinye ilayishwa ubufakazi obuphindwe kabili i-WLL yayo.

 

Izincomo Ezifingqiwe Nezisebenzayo

Isici sokuphepha esingu -7:1  siyipharamitha yedizayini ebalulekile ehlinzeka ngemajini yokuphepha phakathi kwamandla okuphuka kwesihlilingi kanye nomkhawulo wayo womthwalo osebenzayo. Lesi sici sibangela izimo zomhlaba wangempela—ukulayisha ukushaqeka, ukucekelwa phansi kwemvelo, ukuguga, nezici ze-engeli—ezingonakalisa amandla e-sling.

 

Okuthathwayo okubalulekile:

 

1.7:1 igunyazwe yi-EN 1492-1/2 kanye ne-AS 4497:2018  yezihlilingi zokwenziwa

 

2.I-WLL ayiwephuli amandla —ungalinge usebenzise amandla okuphuka njengomkhawulo wokusebenza

 

3.Isici esiphezulu sokuphepha sezinto zokwenziwa kungenxa yokuba sengozini kwazo  ku-UV, ukushisa, amakhemikhali, nokulimala ngokomzimba.

 

4.Njalo hlola ithegi yesihlilingi —ibonisa kokubili i-WLL kanye nesici sokuphepha

 

5.Hlola njalo —isici esingu-7:1 siyisivikelo, asithathi indawo yokunakekelwa okufanele

 

I-Lishenflex  ikhiqiza izihlilingi zokwenziwa zokuphakamisa izinto ezinesici sokuphepha esingu-7:1, esihambisana namazinga we-EN 1492-1 kanye ne-EN 1492-2. Imikhiqizo yethu ifaka izimpawu zomthamo ezinemibala ecacile, izinombolo ze-serial ezihlukile ukuze zilandeleke, futhi zilayishwe ubufakazi ukuze kuqinisekiswe ukwethembeka.
