1. Marine life jacket: Iri zvakare ndiro rinonyanya kushandiswa.Inoshandisa EVA furo zvinhu mukati, iyo yakamanikidzwa uye 3D matatu-dimensionally kuumbwa, uye ukobvu hwayo hunosvika masendimita mana (kugadzirwa kwemumba zvidimbu 5-6 zvebvudzi rakatetepa, ukobvu hunenge 4 cm) 5-7 cm) , mabhachi ehupenyu anogadzirwa zvinoenderana neyakajairwa maitiro ane yavo buoyancy miyero, iyo inowanzoita 7.5 kg / 24 maawa kune vakuru, izvo zvinoreva kuti buoyancy yevakuru inogona kuramba ichisvika 7.5 kg mushure mekunyura mugungwa kwemaawa makumi maviri nemana.

2. Self-inflating life jacket: Iri rudzi rwebhachi rehupenyu rinowanzoshandiswa pakubata hove.Iyo yemukati inovakwa nematanda maviri epamusoro-simba remakemikari zvinhu.Kana iwe ukawira mumvura, dzvanya bhatani rekurudyi, uye rutivi rworuboshwe rwunongofemera mweya, nepo chiratidziri chichiichengeta kusvika yazara.Iyo jasi rehupenyu rinowedzera buoyancy i10 kg / 24 maawa, asi rinofanira kuchengetwa kure kure nereef sezvinobvira kudzivirira kukuvara.

3. Bhachi rokuredzesa maoko rokuredza rokwe: Midziyo yokuredza matombo, ane mabhatani maviri kumberi anofanira kudhonzwa zvakasimba pakuaisa.Pamusoro pezvo, kune miviri miviri ye-elliptical luminous pachipfuva chebhachi rehupenyu kana pamapfudzi, ayo anonyanya kushandiswa kununura mugungwa.Paunosarudza, teerera kana pane slits, uye funga nezvemuvara uye jira.

Inofanira kushambidzwa mukati nekunze nebhurashi mushure mekushandiswa kwega kwega, yozoshambidzwa nemvura yakachena uye yoomeswa munzvimbo ine mhepo inofefetera kuti ive nechokwadi chekugara kwayo kwenguva refu.Iyo inozivikanwa mhando yehupenyu yekuredza vest haingoite basa reyakajairwa life vest, asi zvakare ine inopenya uye inovheneka-emitting mitsetse yeyambiro uye imwechete muhomwe mudziyo sevhare rehove, zvichibvumira mubati wehove kuti awedzere kuchengeteka uku aine zvakakwana. nzvimbo yekuchengetedza hove zvishandiso, zvinobudirira kuuraya shiri mbiri nebwe rimwe.
