Kodi Ndingajowine Masamba Awiri A Flat Pamodzi Kuti Nditalikitse Utali?

Legeni yopyapyala yomwe ndi yaifupi mapazi pang'ono kwambiri imatha kuyimitsa ntchito yokweza. Lingaliro laposachedwa: bwanji osangophatikiza gulaye ziwiri pamodzi? Mchitidwe wolumikiza gulaye ndi wofala, koma malinga ndi OSHA 1910.184 (c) (2) ndi ASME B30.9, gulaye sidzafupikitsidwa kapena kutalikitsidwa ndi knotting kapena kupindika, kapena kulumikizidwa ndi knotting.

Polyester vs. Nylon Flat Slings: Chemical Resistance and Elongation Profiles

Kusankha pakati pa poliyesitala lathyathyathya ndi nayiloni lathyathyathya gulaye si nkhani 'yabwino' kuposa ina-zimadalira kwathunthu malo ntchito. Zida zonsezi zimagawana malire olemetsa ogwirira ntchito komanso kutentha (-40 ° C mpaka 100 ° C) pansi pa EN 1492-1, koma zimasiyana kwambiri pakutalikirana, kukana kwamankhwala, ndi kuyankha kwa chinyezi. Nayiloni imatambasula 6-10% pamtengo wovomerezeka ndipo imatsutsa alkalis koma imawonongedwa ndi zidulo. Polyester imatambasula 3-4% yokha ndipo imakana ma asidi koma imawonongeka ndi alkalis. Bukhuli limapereka kufananitsa kwatsatanetsatane kuti athandize mainjiniya ndi akatswiri opangira zida kuti asankhe zida zoyenera zopangira gulayeti zomwe amagwirira ntchito.

Nthawi Yomwe Mungasinthire Malo Ophwanyika: Chitsogozo cha Njira Zoyendera pafupipafupi komanso pafupipafupi

Kudziwa nthawi yoti mulowe m'malo mwa ma slings athyathyathya ndikofunikira pakusungitsa chitetezo komanso kutsata malamulo. Miyezo yamakampani ASME B30.9 ndi EN 1492-1 imatanthawuza magawo awiri owunikira - pafupipafupi (tsiku ndi tsiku kapena asanagwiritse ntchito) komanso pakanthawi (pachaka kapena theka-pachaka) - iliyonse ili ndi njira zodziwira nthawi yomwe gulaye iyenera kuchotsedwa ntchito. Bukhuli likufotokoza kusiyana pakati pa kuyendera pafupipafupi ndi nthawi ndi nthawi, limapereka mndandanda watsatanetsatane wa aliyense, ndikuwonetsa njira zopuma pantchito zomwe zimayambitsa kusintha kwa gulaye. Kwa oyang'anira mabizinesi, oyang'anira chitetezo, ndi ogwira ntchito, iyi ndi njira yothandiza yosunga zosungira zotetezeka.

Physics of Flat Slings: Momwe Malo Otalikira Amachepetsera Kupanikizika ndi Kuteteza Katundu

Legeni yathyathyathya imachita zambiri osati kungonyamula katundu, koma imateteza. Malo otalikirapo, ophwanyika amagawa kulemera kwa katundu pamalo okulirapo, kumachepetsa kwambiri kupanikizika pamalo aliwonse. Ili ndiye mfundo yofunikira yafizikiki kumbuyo kwa ma slings athyathyathya: Pressure = Force ÷ Area. Powonjezera malo olumikizirana, ma gulayeti athyathyathya amachepetsa chiwopsezo cha kuwonongeka kwa pamwamba, madontho, ndi kuphwanyidwa, zomwe zimapangitsa kuti zikhale chisankho chomwe chimakonda kukweza zida zosalimba, zomalizidwa kapena zowonongeka mosavuta. Bukhuli likufotokoza za fiziki ya kugawa kwamakasitomala, kufanizitsa ma gulayesi athyathyathya ndi njira zina zonyamulira, ndipo limapereka chitsogozo chothandiza posankha m'lifupi mwake momwe mungagwiritsire ntchito gulaye.
