Mingaki iminyaka intambo yokuphepha ichithwe?

I-athikili 5.2.2 ye-ASTM standard F1740-96(2007) iphakamisa ukuthi impilo ende yesevisi yentambo yiminyaka eyi-10.IKomidi le-ASTM lincoma ukuthi intambo yokuvikela ukuphepha kufanele ishintshwe ngisho noma ingazange isetshenziswe ngemva kweminyaka eyishumi yokugcina.

Uma sikhipha intambo yokuphepha ukuze isebenze futhi siyisebenzise endaweni engcolile, enelanga futhi kunemvula, ukuze ikwazi ukugijima ngokushesha kuma-pulleys, abaxhumi bezintambo kanye nabahamba kancane, izoba yini imiphumela yalokhu kusetshenziswa?Intambo iyindwangu.Ukugoba, ukuhlanganisa, ukusetshenziswa endaweni emagebhugebhu kanye nomjikelezo wokulayisha/wokukhipha konke kuzodala ukuguga kwefayibha, ngaleyo ndlela kunciphise amandla okusebenzisa intambo.Kodwa-ke, akucaci ukuthi kungani umonakalo omncane wezintambo uzonqwabelana ube ngumonakalo omkhulu, futhi isizathu sokuthi kungani amandla okusebenzisa izintambo ngokusobala encishisiwe.

UBruce Smith, umbhali kanye naye we-On Rope, waqoqa futhi wagqabula izintambo zesampula ezingaphezu kwe-100 ukuze kuhlolwe umhume.Ngokusetshenziswa kwezintambo, amasampula ahlukaniswa ngokuthi “amasha”, “ukusetshenziswa okuvamile” noma “okuhlukunyeziwe”.Izintambo “ezintsha” zilahlekelwa amandla angu-1.5% kuya ku-2% njalo ngonyaka ngokwesilinganiso, kuyilapho izintambo “zokusetshenziswa okuvamile” zilahlekelwa amandla angu-3% kuya ku-4% minyaka yonke.USmith uphethe ngokuthi “ukugcinwa kahle kwezintambo kubaluleke kakhulu kunokuphila kwezintambo.”Mingaki iminyaka intambo yokuphepha ichithwe?

Ukuhlola kukaSmith kufakazela ukuthi uma isetshenziswa kancane, intambo yokuhlenga ilahlekelwa amandla angu-1.5% kuya ku-2% minyaka yonke ngokwesilinganiso.Uma isetshenziswa njalo, ilahlekelwa amandla angu-3% kuya ku-5% njalo ngonyaka ngokwesilinganiso.Lolu lwazi lungakusiza ukuthi ulinganisele ukuncipha kwamandla entambo oyisebenzisayo, kodwa alukwazi ukukutshela kahle ukuthi kufanele uyisuse yini intambo.Nakuba ungakwazi ukulinganisa ukwehla kwamandla entambo, kufanele futhi wazi ukuthi yikuphi ukulahlekelwa amandla okuvumelekile ngaphambi kokuba intambo ikhishwe.Kusukela namuhla, alikho izinga elingasitshela ukuthi intambo yokuphepha esetshenzisiwe kufanele ibe namandla kangakanani.

Ngaphezu kokulahlekelwa ukuphila kweshelufu namandla, esinye isizathu sokuqeda izintambo ukuthi izintambo zilimele noma izintambo zibe nomonakalo osolisayo.Ukuhlola okufika ngesikhathi kungathola iminonjana yomonakalo, futhi amalungu eqembu angase abike ngokuhamba kwesikhathi ukuthi intambo ishaywe umthelela, ishaywe amatshe noma inhlabathi phakathi kwe-stretcher nodonga.Uma unquma ukuqeda intambo, yihlukanise futhi uhlole ingaphakathi lendawo elimele, ukuze wazi kabanzi mayelana nezinga lesikhumba sentambo esilimele futhi usengakwazi ukuvikela umgogodla wentambo.Ezimweni eziningi, umgogodla wezintambo ngeke wonakaliswe.

Futhi, uma unokungabaza ngobuqotho bentambo yokuphepha, yisuse.Izindleko zokushintshwa kwemishini azibizi ngokwanele ukufaka izimpilo zabatakuli engozini.
