Iindaba - Isikhokelo seLashing Chains

Kwimeko yokuthuthwa kwemithwalo enzima kakhulu, kunokuba lula kakhulu ukubopha imithwalo ngokufaka imixokelelwane evunyiweyo ngokwemigangatho ye-EN 12195-3, endaweni yokusebenzisa imixokelelwane yewebhu evunyiweyo ngokwemigangatho ye-EN 12195-2. Oku kwenzelwa ukunciphisa inani lemixokelelwane efunekayo, kuba imixokelelwane yemixokelelwane inika amandla okukhusela aphezulu kakhulu kunemixokelelwane yewebhu.

Iimpawu zeTyayini

Iinkcukacha kunye nokusebenza kweetyathanga ezijikelezayo ezinokusetyenziselwa ukubopha imithwalo kwiindlela zokuthutha zichazwe kwi-EN 12195-3 standard, iityathanga ezibotshelelweyo. Njengeetyathanga zewebhu ezisetyenziselwa ukubopha imithwalo, iityathanga ezibotshelelweyo azinakusetyenziselwa ukuphakamisa, kodwa zisetyenziselwa ukubopha imithwalo kuphela.

Iintambo zokugquma kufuneka zixhotyiswe ngepleyiti ebonisa ixabiso le-LC, oko kukuthi, amandla okugquma entambo achazwe kwi-daN, njengoko kubonisiwe kumzekelo kumfanekiso.

Ngokwesiqhelo imixokelelwane yokuqhobosha iba yeyohlobo olufutshane loqhagamshelo. Eziphelweni kukho iihoko okanye amaringi athile ekufuneka afakwe kwisithuthi, okanye aqhagamshele umthwalo xa kukho ukuqhobosha ngokuthe ngqo.

Iintambo zokuLashing zibonelelwa ngesixhobo sokuxinanisa. Le inokuba yinxalenye esisigxina yentambo yokulashing okanye isixhobo esahlukileyo esinamathele kwintambo yokulashing ukuze ixinaniswa. Kukho iintlobo ezahlukeneyo zeenkqubo zokuxinanisa, ezifana nohlobo lweratchet kunye nohlobo lwebhakede lokujika. Ukuze kuhambelane nomgangatho we-EN 12195-3, kuyimfuneko ukuba kubekho izixhobo ezikwaziyo ukuthintela ukukhululeka ngexesha lokuthuthwa. Oku kuya kuphazamisa ukusebenza kokuqiniswa. Indawo yokulahlwa emva kokuxinanisa kufuneka inqunyelwe kwi-150 mm, ukuze kuthintelwe ukubakho kweentshukumo zomthwalo ezinokubangela ukulahleka koxinzelelo ngenxa yokuzinza okanye ukungcangcazela.

Ukusetyenziswa kweetsheyini xa kunxitywa ngqo

Ukusetyenziswa kweeLashing Chains

Inani elincinci kunye nolungiselelo lweentambo zokuqhawula zinokumiselwa kusetyenziswa iifomyula ezikwimigangatho ye-EN 12195-1, ngelixa kuyimfuneko ukujonga ukuba iindawo zokuqhawula intambo zesithuthi apho iintambo zincamathiselwe khona zinika amandla aneleyo, njengoko kufuneka ngokomgangatho we-EN 12640.

Hlola phambi kokuba uyisebenzise ukuqinisekisa ukuba imixokelelwane yokuqhawula imitya ikwimeko entle kwaye ayigugi kakhulu. Xa igugisiwe, imixokelelwane yokuqhawula imitya idla ngokunwebeka. Umthetho oqhelekileyo uyalela ukuba kuthathwe njengemixokelelwane egugisiweyo kakhulu enobude obungaphezulu kwe-3% yexabiso lethiyori.

Kufuneka kuqatshelwe ngokukodwa xa imixokelelwane yokuxhuzula idibana nomthwalo okanye nenxalenye yesithuthi, njengodonga. Imixokelelwane yokuxhuzula ivelisa ukungqubana okukhulu nenxalenye yokuxhuzula. Oku, ukongeza kumonakalo kumthwalo, kunokubangela ukulahleka koxinzelelo kumasebe ekhonkco. Ke ngoko, ngaphandle kokuqwalasela amanyathelo athile okhuseleko, kuyacetyiswa ukusebenzisa imixokelelwane kuphela ekuxhuzuleni ngokuthe ngqo. Ngale ndlela inqaku lomthwalo kunye nenqaku lesithuthi ziqhagamshelwe yikhonkco lokuxhuzula ngaphandle kokudibana nezinye izinto, njengoko kubonisiwe kumfanekiso.
