Chidziwitso Chofala Chokhudza Chingwe Chomangirira cha Ratchet

SHF:

Mphamvu yokhazikika ya dzanja: Mphamvu yogwiritsira ntchito dzanja ya 500N(50daN pa chizindikiro).

STF:

Mphamvu yokhazikika yogwira ntchito: Mphamvu yotsalira pambuyo potulutsa chogwirira cha chogwirira cha ratchet.

Kutalika:

Muyeso wa kutambasula, pa katundu woperekedwa, umafotokozedwa ngati peresenti ya kutalika koyambirira komwe sikunatulutsidwe. Zipangizo zonse zomwe zili ndi mphamvu zidzatambasuka ndipo zipangizo zosiyanasiyana zimakhala ndi mphamvu zosiyana za kutambasula pa katundu wofanana wa mphamvu.

Pa lamba wa ratchet, kutalika kwa chingwecho ndi 4% mpaka 7%.

Kutentha:

Mangani lamba pogwiritsa ntchito polypropylene kapena polyester webbing musagwiritse ntchito kutentha kopitirira 90℃ kapena pansi pa -40℃.

Kukonza:

Sipadzakhala kukonzanso maukonde, ma ratchet buckle, ma hook kapena ma strapping/socking patterns.

Muyezo:

EN 12195-2, AS/NZS 4380, ndi WSTDA-T-1 ndi miyezo yonse yomwe imayang'anira zofunikira, mayeso, ndi kagwiritsidwe ntchito ka zingwe za ratchet ndi zomangira zomangira zomwe zimagwiritsidwa ntchito poteteza katundu. Ngakhale kuti zimafanana pa cholinga, zimasiyana malinga ndi komwe zimachokera, zofunikira zake, ndi njira zoyesera.
