Kunzwisisa mamakisi emaketani kwakakosha pakusarudza cheni yakakodzera yekushandiswa mumaindasitiri, kusimudza, kana kuchengetedza. Nemhando dzakasiyana dzeketani dziri pamusika, tingaziva sei kana tiri kushandisa mamakisi chaiwo emaketani kumapurojekiti edu? Danho rekutanga nderekuziva mamakisi emaketani, kupera kwemaketani uye zvazvinoreva.
Chii chinonzi Chain Grades?
Magiredhi echeni inzira yekuronga cheni dzesimbi dze alloy zvichienderana nesimba radzo rekudhonza uye muganho wemutoro wekushanda (WLL). Kana giredhi rayo rakakwirira, cheni yacho inosimba uye yakaoma.
| Giredhi | Zvinhu | Simba reKusimba (psi) | Kushandiswa Kwakajairika |
| Giredhi 30 | Koiri yeUchapupu (kabhoni) | ~30,000 | Basa rakareruka: kubatanidza, zvipingamupinyi |
| Giredhi rechi43 | Muedzo Mukuru (kabhoni) | ~43,000 | Kusunga mutoro, kudhonza, kunyora matanda |
| Giredhi 70 | Kutakura (chishongo) | ~70,000 | Cheni yekutakura, kusungirirwa kwemarori |
| Giredhi 80 | Simbi yesimbi | ~80,000 | Cheni yekusimudza, cheni yemasango, tambo |
| Giredhi 100 | Simbi yesimbi yepamusoro-soro | ~100,000 | Kusimudza zvinhu zvinorema, marongero, kusimudza zvinhu pamusoro |
| Giredhi 120 | Simbi yesimbi yakawedzerwa | ~120,000 | Kusimudza zvinhu zvinorema zvakakosha |
Mashoko Akakosha Ekuziva:
1. Muganho weMutoro weKushanda (WLL):Huremu hwakanyanya hunogona kusimudzwa neketani zvakachengeteka.
2. Simba reKusimba:Cheni yakasimba inogona kumira isati yatyoka.
3. Bvunzo reUchapupu:Kuedzwa pamutoro wakatarwa (kazhinji 2x WLL) kuve nechokwadi chekuti hapana zvikanganiso.
Kupedzisa kweChain:
Heino pfupiso pfupi yezvavanoreva:
1. Inozvipenda yega:hapana kupedzisa kana kuputira
2. Okisijeni nhema:Black oxide kana kuti blackening ipurasitiki inogadzirwa nezvinhu zvesimbi, inoshandiswa kuwedzera ngura, kuti ionekwe zvakanaka, uye kuderedza kupenya kwechiedza.
3. Magetsi akabatidzwa:electroplating yekuisa zinc pamusoro, inoiswa mu zinc salt solution, uye magetsi anoisa zinc layer yakatsetseka, inopenya, yakatetepa, yakafanana.
4. Kupisa kwakanyungudutswa:Inosanganisira kunyudza simbi mu zinc yakanyungudutswa panosvika 450°C, Zinc inosangana nesimbi kuti igadzire zvidimbu zvakakora zve zinc-iron alloy, Inopa dziviriro iri nani yengura kwenguva refu, kunyanya kunze.
5. Hupfu hwakaputirwa: Kuputira hupfu rudzi rwekuputira runoshandiswa sehupfu hwakaoma hunoyerera huchiyerera.Kuputira hupfu kunogona kugadzira machira akakora kupfuura emvura asingamhanye kana kutsvedza.
Cherechedza:Magiredhi 80 zvichikwira chete ndiwo anotenderwa kusimudza zvinhu zvinorema zvichienderana neOSHA neASME standards.
Kusarudza Chain Yakakodzera：
1.Sarudza mutoro:Ziva huremu uye chinhu chekuchengetedza.
2. Zvakatipoteredza:Inoparadza, inopisa zvakanyanya, nezvimwewo.
3. Mashandisirwo:Kusimudza, kudhonza, kusunga, nezvimwewo.
4. Mitemo:OSHA, DOT, kana kumwe kutevedzera mitemo.
Mhedziso:
Zvino zvawava kunzwisisa mutsauko uripo pakati pemhando dzakasiyana dzecheni, unogona kushanda zvakachengeteka uye kusarudza cheni yakakodzera iwe. Uye kana uchitsvaga cheni yemhando yepamusoro, G80 kana G100 lifting hook, chain sling, kana uine mibvunzo nezve zvaunoda, taura nesu pano paQingdao Well Done Imp & Exp Co., Ltd.. Nyanzvi dzedu dzichafara kukubatsira kuwana zvaunoda.
