Zikumveka zosavuta - tiyeni tingopanga maulalo kukhala akulu. Koma kukhala ndi maulalo okulirapo kumabwera pamtengo. Timafunikirabe maulalo athu kuti akhale olimba mokwanira. Mkati mwa malire a mphamvu zomwe zilipo zitsulo izi nthawi zonse zimatanthawuza maulalo amafuta opangidwa ndi mainchesi okulirapo. Izi zitha kukhala zovuta kupeza zolumikizira kuti zigwirizane.
Maulalo ambiri amakhala ndi malo oponderezedwa kuti athandizire kulumikizana ndi unyolo. Ndikofunikira kuyang'ana pakamwa pakamwa pa cholumikizira komanso m'mimba mwake ngati mukufuna kuwona ngati ikufanana ndi masterlink kapena shackle.
Kugwiritsa ntchito ulalo wokhala ndi chopindika chokhazikika kuti mugwirizane.
Mphamvu
Koma kodi masterlink iyenera kukhala yamphamvu bwanji? Pansi pa mfundo za ku Australia za gulayeni, ulalo wa gulaye* uli wonse uyenera kukhala ndi katundu wosweka wa 4:1 - chimodzimodzi ndi momwe amachitira ndi gulayeni.
Izi siziri choncho mosasamala kanthu za kusweka kwa mitundu yosiyanasiyana ya mwendo wa gulaye: unyolo, chingwe cha waya, gulayeni, gulaye, ndi zina zotero. zovuta zakuthupi zosiyanasiyana zimaganiziridwa. Izi sizimakhudza mwachindunji zoyikapo unyolo, kotero kuti katundu wawo wosweka amakhalabe momwe amachitira ndi gulaye.
Izi sizili choncho m'mayiko ena, ndipo malamulo a m'deralo ayenera kutsatiridwa.
* Pali zina, kuphwanya katundu wa gulaye lonse kwa ogwira ntchito crane workbox ndi kuwirikiza kawiri, kotero ulalo amene angakhale 4:1 ndi 8:1 pamene kusinthidwa kwa bokosi ntchito.
Pali zambiri kwa izo ndithudi. Masterlink iliyonse iyenera kukhala ductile, iyenera kuthana ndi moyo wanthawi zonse wogwira ntchito, ndipo iyenera kupulumuka kuyesedwa kwa umboni.
Chain gulaye ndi Master Link mukamayesa
Chofunika kwambiri - ma masterlink sakhala umboni payekhapayekha mpaka atapangidwa kukhala gulaye yomwe yayesedwa umboni. Pa gawo loperekera gawo la masterlinks ndi zitsanzo zoyesedwa pa mandrels.
Kuyesa umboni ndi gawo lofunikira popanga masing'i odalirika. Pali magawo osiyanasiyana omwe amalumikizana kuti kuyezetsa kumapereka chitsimikizo chofunikira kuti zigawo zonse ndi mphamvu zofananira ndi WLL yolembedwa - ndipo zidzapulumuka zovuta zogwiritsidwa ntchito popanda kupunduka.
Kuyezetsa kumatetezanso ku zolakwika zamagulu.
Masterlink yokhala ndi vuto lopanga lazindikirika pakupakidwa umboni.
Zofunikira
Zofunikira
Master Links ndi gawo lofunikira pankhani yokweza chokweza pamwamba pomwe ndi malo olumikizirana ndi ma slings ndi kugwiritsa ntchito mitundu ina ya gulaye.
Mabuku athunthu akhoza kulembedwa okhudza masterlinks ndipo timatha kungokhudza zina mwazofunikira apa:
• Maulalo apamwamba a ma gulayendo angapo ayenera kukonzedwa bwino
• Kusiyana kwa milingo ndi mavoti kuyenera kuganiziridwa posankha zigawo
• Ayenera kulumikizana moyenera ndi gulaye ndi mbeza.
• Ayenera kukhala amphamvu mokwanira.
…komanso osachepera, tiyenera kuyang'ana tag yofananira ndi satifiketi yoyeserera ya masterlink yoperekedwa ngati gawo la msonkhano wa gulaye.
Masterlinks ndi abwino kwambiri monga momwe amapangira, kugwiritsa ntchito komanso kuyang'anira kosalekeza.
Ayenera kusankhidwa nthawi zonse ndikuwunikiridwa ndi munthu woyenerera.
