Inspection standards for hand chain hoists

Iyo yekuongorora zviyero zve hand chain hoists kunyanya zvinosanganisira zvinotevera zvinhu:

Kuongorora kwechitarisiko: Tarisa uone kana goko recheni hoist rakachena uye rakachena, uye kana paine kukuvara kuri pachena, deformation kana makatsemuka.

Kuongorora kwegiya: Tarisa uone kana giya recheni remaoko rakatyoka mazino, kupfeka, nezvimwe, uye kana richikwanisa kutenderera zvakajairika.

Kuongorora hoko: Tarisa uone kana hoko yakaremara, yakakuvadzwa, uye kana inogona kuvhurwa nekuvharwa zvakajairika.

Kusimudza cheni yekuongorora: Tarisa uone kana cheni yekusimudza yakapfekwa kana kutyoka. Kana pane dambudziko, rinoda kuchinjwa.

Kuongorora kwebhureki: Tarisa kuti bhureki rinogona kubhureka zvakajairwa uye rakaiswa pagiya. Tarisa uone kana paine kuregedzera.

Hapana-mutoro bvunzo: Tarisa mamiriro ekushanda echeni hoist kana pasina mutoro, uye kana paine chero jamming chiitiko.

Rated load test: Inoitwa pabhenji rekuyedza rakakosha kuona kana tambo yetambo sitiroko yechanza cheni yekusimudza ichizadzikisa zvinodiwa.

Dynamic load test: Inoitwa pabhenji rekuyedza rakakosha kuyedza kuti tambo yekufamba kureba inosangana nezvinodiwa kana yaiswa ka1.1 pane yakayerwa mutoro.

Static load bvunzo: Inoitwa pabhenji rekuyedza rakakosha kuyedza kuti zvivhariso uye maplate ekusunga zvinokanganisa mashandiro kana akaremerwa ka1.5 nguva yakayerwa mutoro.

Hook test: Zvishoma nezvishoma kurodha pakati pehoko mhango pamushini wekuyedza zvinhu kusvika kaviri payakayerwa mutoro uye 4 nguva dzakarongerwa mutoro kuti utarise kana deformation yemuromo wehokwe inodarika kukosha kunobvumidzwa.

Kuvimbika bvunzo: Ramba uchidhonza danda rekumberi uye reverse tsvimbo kumashure neshure pasi pemutoro wakayerwa, kuitira kuti kuwedzeredza kumashure-uye-mberi sitiroko yetambo yewaya isiri pasi pe120 metres, uye ongorora kana chikamu chimwe nechimwe chisina kujairika.

Zvimwe zvinhu zvekuongorora: zvinosanganisira kutenderera kwetambo yetambo yekupedzisira, kupfava kweiyo clamping ndiro, riveting mhando uye pendi mamiriro ezvikamu, nezvimwe.

Ongororo dziri pamusoro apa ndedzekuona kushanda kwakajairwa uye kuchengetedzeka kwecheni yeruoko, uye nekupa hwaro hwekuchengetedza midziyo.
