Nsobola Okukozesa Flat Sling mu Nsengeka ya Choke Hitch?

Abakozi abakola ebyuma beetaaga okusitula omugugu ogw’ekika kya ssiringi — payipu ey’ekyuma, empagi ya seminti oba ekibinja ky’embaawo. Omu flat sling  gye bakwata okuva ku rack ye buwanvu obutuufu n’obusobozi. Naye omugugu tegulina bifo bitegeerekese ebikwatagana. Omuvuzi w’ebyuma azinga sling ku mugugu, n’ayita eriiso erimu mu eddala, n’aginyiga nnyo. Kino kiziyiza (choke hitch) —era kiyinza okuba eky’okugonjoola ebyuma ekikola obulungi, naye nga kikoleddwa mu butuufu.

 

Lishenflex  emaze emyaka egisukka mu makumi abiri ng’ekola ebyuma ebiyitibwa synthetic flat slings, era obumanyirivu bwaffe mu nnimiro bulaga nti choke hitches bye bimu ku bisinga okukozesebwa obubi sling configurations. Choke hitch erabika nga nnyangu, naye okugikozesa okutali kwa bulabe kisinziira ku kutegeera okukendeeza ku busobozi, choke angle entuufu, n’embeera ya sling. Okusinziira ku biwandiiko by’amakolero  okuva mu bakola sling ezigoberera EN 1492-1, ensonga y’obusobozi bwa choke hitch eri 0.8 —ekitegeeza nti sling ebalirirwamu ttani emu mu vertical lift esobola okutwala kkiro 800 zokka mu ngeri ey’obukuumi mu choke hitch .

 

Choke Hitch Kiki?

Choke hitch ye nsengeka ya rigging nga sling ezingibwa ku mugugu, era enkomerero emu eya sling eyisibwa mu liiso oba fitting erikontana. Olwo omugugu ne gusitulibwa, ekivaako ekiwujjo okunywezebwa okwetooloola omugugu. Kino kikola cinching effect  enyweza omugugu n'okuziyiza okuseerera .

 

Nga bwe kinnyonnyoddwa mu OSHA's Guidance on Safe Sling Use , choker hitch esaanira emigugu egizibu okutebenkeza oba okunyweza n'okusitula okugolokofu okwesimbye . Choker hitch ekwata omugugu obulungi nga gunyweza okwetooloola. Wabula OSHA erabula mu bulambulukufu nti mu choke hitch, choke point erina okuba ku mubiri gwa sling gwokka, never ku splice oba fitting .

 

Ekitongole  kya Rigging Institute  kigamba nti choke hitch y’emu ku sling hitches ssatu ezisookerwako, ku mabbali ga vertical ne basket hitches, era etera okukozesebwa ng’omugugu tegulina bifo bituufu we gunyweza .

 

Okukendeeza ku busobozi mu Choke Hitch

Ensonga esinga obukulu mu kukozesa choke hitch kwe kukendeeza ku busobozi. Ekkomo ly’omugugu gw’okukola ogugereddwa (rated working load limit) lya sling lisinga mu kusika okugolokofu okwesimbye. Bwe kikozesebwa mu choke hitch, obusobozi bukendeera nnyo.

 

Okusinziira ku OSHA Guidance on Safe Sling Use , omugugu ogugereddwa ku sling mu choke hitch gusalibwawo abakola sling era nga gwesigamiziddwa ku angle of choke. OSHA egamba nti obusobozi bwa choke hitch bukola kasita enkoona ya choke eba diguli 120 oba okusingawo. Ku nkoona z’okuziyira ezitasukka diguli 120, omugugu ogugereddwa gulina okwongera okukendeezebwa nga omukozi w’engoye bw’agamba .

 

Ekipande ky’okugeraageranya obusobozi (nga kyesigamiziddwa ku EN 1492-1 polyester flat sling):

 

Ensibuko: EN 1492-1 ebikwata ku busobozi okuva mu CEREX ne Mennens

 

Nga ekipande bwe kiraga, ensonga ya choke hitch (KL) eri 0.8 wansi wa EN 1492-1, ekitegeeza okukendeeza ku busobozi ebitundu 20% bw’ogeraageranya n’okusiba okwesimbye.

 

Ddi Okukuba Choke Hitch Kusaanidde?

Choke hitch esaanidde mu mbeera ezenjawulo:

 

1.Emigugu egitalina bifo bitegeerekese ebikwatagana —emigugu egy’ekika kya cylindrical, payipu, ebibumbe by’embaawo, n’empagi za seminti

 

2.Emigugu egyetaaga okukwatibwa obulungi —okuziyiza okuseerera nga ositula oba okukyukakyuka

 

3.Single-leg lifts —nga basket hitch tekisoboka

 

Nga bwe kyalagulwa Medeer Lifting , choke hitch ya mugaso mu kukwata emigugu obulungi naye nga tenywevu nnyo okusinga vertical hitch era esobola okwonoona sling singa ekozesebwa mu ngeri etasaana . Slings zokka ezikoleddwa okukozesebwa mu choke hitch ze zirina okukozesebwa mu nsengeka eno, era sling erina okwekebejjebwa okulaba oba eyonoonese nga buli kugikozesa n’oluvannyuma lw’okugikozesa.

 

Enkola esinga obulungi:  Mu choke hitch, choke point erina okuteekebwa ku mubiri gwa sling —nete ku liiso, splice, oba fitting . Enkoona ya choke erina okuba 120° oba okusingawo okukuuma ensonga y’obusobozi 0.8 enzijuvu.

 

Ebikulu Ebirina Okulowoozebwako ku Byokwerinda

Tokozesa choke hitch singa:

 

● Sling erina ebisala, okunyiga oba okutunga okwonooneka mu kitundu ekijja okugumira okuziyira

 

● Choke angle eri wansi wa 120° nga tewali kukendeeza busobozi kukwatagana

 

● Omugugu gulina empenda ensongovu eziyinza okusala ebiwuzi by’omugugu (kozesa ebikuuma mu nsonda) .

 

● Omusipi gukyuse oba gunyiganyiga —kino kireeta ebifo ebitali bimu

 

● Ekiwandiiko ekiraga nti sling eno kibula oba tekisomebwa —tosobola kukakasa busobozi obugereddwa

 

OSHA ekugira mu bulambulukufu:

 

● Ensigo eziriko amafundo (okufunza oba okuwanvuya ng’ozisiba oba okuzinyiga tekikkirizibwa) .

 

● Okukozesa sling mu choke hitch nga choke point eri ku splice oba fitting

 

● Okuwummuza emigugu ku sling

 

● Okusika omugugu okuva wansi w’omugugu ng’omugugu guwummudde ku mugugu

 

Lishenflex ’s lab testing confirms that slings with even minor damage —nga localized abrasion oba edge cuts —zifuna okwambala okw’amangu mu choke hitch configurations olw’amaanyi agakuŋŋaanyiziddwa ku choke point. Eno y’ensonga lwaki okusooka okukozesa n’okukebera enfunda eziwera buli ASME B30.9 kikulu nnyo naddala ku slings ezikozesebwa mu choke hitches.

 

Ebyetaago by’okukebera okukozesa Choke Hitch

Slings ezikozesebwa mu choke hitches zirina okwekebejjebwa emirundi mingi okusinga ezo ezikozesebwa mu vertical lifts zokka. ASME B30.9  yeetaaga emitendera esatu egy’okukebera:

 

Emisingi emikulu egy’okuggyawo wansi wa ASME B30.9  ku slings ezipapajjo ezikozesebwa mu choke hitches:

 

● Okutunga okumenyese oba okwambala mu biyungo ebisitula emigugu

 

● Okwokya kwa asidi oba okuziyira

 

● Obujulizi obulaga nti ebbugumu lyonooneka

 

● Ebituli oba amaziga agabikkula obuwuzi obukulu —naddala mu kifo we buziyira

 

● Okwambala okuyitiridde okusiiga

 

● Amafundo mu mubiri gwa sling —okusiba amafundo kikugirwa mu OSHA

 

● Ebitundu okukyusa langi oba ebikutuse ebiraga nti eddagala oba UV byonoonese

 

Mu bufunze n’ebiteeso eby’omugaso

Flat sling  esobola okukozesebwa mu choke hitch configuration, naye okukozesa kulina okutuukirirwa n’obwegendereza n’obusobozi.

 

Ebikulu ebigenda okutwalibwa:

 

1.Capacity reduction is non-negotiable —a choke hitch ekendeeza WLL okutuuka ku 80% ku busobozi obwesimbye wansi wa EN 1492-1

 

2.Choke angle ensonga —kuuma 120° oba okusingawo for full 0.8 factor; okukendeeza ku busobozi bw’enkoona entonotono buli bulagirizi bw’omukozi

 

3.Never choke ku splice oba fitting —ekifo ekiziyira kirina okuba ku mubiri gwa sling

 

4.Kebera nga tonnaba n’oluvannyuma lw’okukozesa —choke hitches concentrate stress; kebera oba waliwo ebyonoonese mu kitundu

 

5.Kozesa ebikuuma enkoona —ku migugu egirina empenda ezisongovu

 

Lishenflex  ekola slings za polyester flat slings nga zirina amaaso aganywezeddwa n’obubonero obulaga obusobozi obulaga langi ezitegeerekeka obulungi, nga zituukana n’omutindo gwa EN 1492-1 ne ASME B30.9. Ebintu byaffe bigezesebwa ku nsengeka zonna eza hitch, omuli ne choke hitches, era tuwa okutendekebwa mu kwekebejja okuwagira enkola za rigging ezitali za bulabe.

 

Bw’oba ​​weetaaga obuyambi okuzuula oba slings zo eza flat eziriwo kati zisaanira okukozesebwa mu choke hitch —oba nga weetaaga okulambika ku kubala obusobozi ku geometry yo ey’okusitula entongole —nsaba oweereze email ku sales@lishenflex.com , era ttiimu yaffe ey’ekikugu ejja kuwa obuyambi obw’omuntu ku muntu.
