Miyero yekuedza ye lever hoists

Test standard zvinhu zve lever hoists

(1) Hapana-mutoro bvunzo: Dhonza iyo yekumberi lever uye reverse lever kumashure uye mberi katatu kana pasina mutoro, uye tarisa mamiriro ekushanda eiyo michina. Hapafanirwe kuita jamming.

(2) Yakatemerwa mutoro bvunzo: Yakayedzwa payakakosha bhenji rekuyedza, ruoko rwekudhonza ruoko uye inodzokorodza waya tambo sitiroko yemubato inofanirwa kusangana nezvinodiwa.

(3) Dynamic mutoro bvunzo: Muedzo pane yakakosha bhenji rekuyedza, takura pa 1.1 nguva yakatarwa mutoro, kusimuka nekudonha kamwe, uye tambo yetambo yekufamba kure haifanirwe kuve isingasviki 200mm nguva imwe neimwe. Muchina wese unofanirwa kushanda zvakanaka uye zvakavimbika.

(4) Static load bvunzo: Pabhenji rakakosha rekuyedza, zvishoma nezvishoma takura kusvika 1.5 nguva yakatarwa mutoro uye gara kwemaminitsi gumi. Iwo maclamps uye clamping mahwendefa haakonzeredze deformation inokanganisa mashandiro.

(5)Hook test:

① Pamuchina wekuyedza zvinhu, zvishoma nezvishoma kurodha kusvika ku2 nguva yakayerwa mutoro kuburikidza nepakati pehoko mhango, wozobvisa mutoro mushure mekugara kweminiti imwe. Tarisa deformation yehoko yemuromo, iyo isingapfuuri 0.25%;

② Pamuchina wekuyedza zvinhu, zvishoma nezvishoma kurodha kusvika ku4 nguva yakayerwa mutoro kuburikidza nepakati pehoko mhango, uye hoko inofanirwa kutsigira yakavimbika kweminiti imwe.

(6) Kuvimbika bvunzo: Pasi pemutoro wakayerwa, ramba uchidhonza chireveredzo chemberi uye dzosera kumashure kumashure uye kumashure kuitira kuti kuwedzera-uye-kubuda sitiroko yetambo yetambo isiri pasi pe120m (inogona kuitwa muna kana, asi nguva imwe neimwe, asi iyo yakawedzera sitiroko yetambo tambo nguva imwe neimwe 30m, uye kupindirana pakati peawa imwe neimwe hakubvumidzwe kupfuudza tambo imwe neimwe nguva. bvunzo). Hakufanirwe kuve neabnormality mune chero chikamu chelever hoist.

(7) Kuongororwa kwehutano hwechitarisiko: Pamusoro pehoko inofanira kuva yakatsetseka uye yakachena, uye hapafaniri kuva nemabhura, kuputika, kupeta, kana kukanganisa kwenzvimbo kunoderedza simba; hapana kugadzirisa welding inobvumirwa pane hook. Iyo yepamusoro yeplamping plate inofanirwa kuve yakatwasuka uye isina burrs. Migumo yetambo yetambo inofanira kutenderedzwa uye kwete kusununguka. Hapana mapfundo, mapundu kana twists zvinotenderwa mutambo yese. Kutsemuka kwezvikamu kunofanira kunge kwakasimba, uye misoro yakatsemuka haifanirwe kunge iine hurema hwakadai semheni, kutsemuka, kana kukwenya. Chikamu chakapendwa chinofanira kuva chakaenzana uye chakajeka muvara. Panofanira kunge pasina mavara, mabubbles, wrinkles, peeling uye roughness.
