Totalt sett, i henhold til forskjellige produksjonsmetoder, kan den deles inn i smidde kroker og laminerte kroker. I henhold til deres forskjellige former kan de deles inn i enkeltkroker og doble kroker.<\/p>\n\n\n\n<p>I dag vil vi introdusere de to vanligste typene:<\/p>\n\n\n\n<p>(1) Skj\u00e6r kroken<\/p>\n\n\n\n<p>Skivekroker er delt inn i enkle kroker og doble kroker. Denne typen krok har en enkel struktur, p\u00e5litelig drift og praktisk vedlikehold. Enkeltkroker brukes ofte p\u00e5 st\u00f8pekraner, mens doble kroker ofte brukes i kraner for generell bruk som veier over 100 tonn.<\/p>\n\n\n\n<p>(2) Smidd krok<\/p>\n\n\n\n<p>Smidd kroker er delt inn i enkle kroker og doble kroker. Fordi kraften p\u00e5 en enkelt krok kan avvike, er den ikke like stabil som den symmetriske kraften p\u00e5 en dobbel krok. Derfor bruker sm\u00e5 og mellomstore kraner med en vekt p\u00e5 under 75 tonn ofte en enkelt krok. Kraner med en tonnasje p\u00e5 over 75 tonn bruker ofte doble kroker.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"https:\/\/d3fnmw4lwrx8lm.cloudfront.net\/wp-content\/uploads\/2023\/06\/13111421\/crane-hooks.jpg\" alt=\"krankroker\" class=\"wp-image-4190 lazyload\"\/><noscript><img decoding=\"async\" width=\"750\" height=\"563\" src=\"https:\/\/d3fnmw4lwrx8lm.cloudfront.net\/wp-content\/uploads\/2023\/06\/13111421\/crane-hooks.jpg\" alt=\"krankroker\" class=\"wp-image-4190 lazyload\" srcset=\"https:\/\/d3fnmw4lwrx8lm.cloudfront.net\/wp-content\/uploads\/2023\/06\/13111421\/crane-hooks.jpg 750w, https:\/\/d3fnmw4lwrx8lm.cloudfront.net\/wp-content\/uploads\/2023\/06\/13111421\/crane-hooks-300x225.jpg 300w, https:\/\/d3fnmw4lwrx8lm.cloudfront.net\/wp-content\/uploads\/2023\/06\/13111421\/crane-hooks-428x321.jpg 428w, https:\/\/d3fnmw4lwrx8lm.cloudfront.net\/wp-content\/uploads\/2023\/06\/13111421\/crane-hooks-345x258.jpg 345w, https:\/\/d3fnmw4lwrx8lm.cloudfront.net\/wp-content\/uploads\/2023\/06\/13111421\/crane-hooks-253x190.jpg 253w\" sizes=\"(max-width: 750px) 100vw, 750px\" \/><\/noscript><\/figure>\n\n\n\n<p>2\u3001 Hvordan gj\u00f8re en god jobb i daglig vedlikehold av kroker?<\/p>\n\n\n\n<p>Sikkerheten og stabiliteten til kroker spiller en viktig rolle i sikker produksjon. Brukerenheten b\u00f8r regelmessig utf\u00f8re daglige sikkerhetsinspeksjoner og vedlikehold p\u00e5 kroken. Generelt sett inkluderer den daglige inspeksjonen og vedlikeholdet av kroker f\u00f8lgende:<\/p>\n\n\n\n<p>(1) Rengj\u00f8r hoveddelen av <a href=\"https:\/\/www.sevencrane.com\/nb\/product\/crane-hook\/\">krankrok<\/a> monter med et ikke-etsende organisk l\u00f8semiddel, t\u00f8rk det t\u00f8rt og inspiser det med et forst\u00f8rrelsesglass. Hvis det oppdages sprekker, b\u00f8r de skiftes ut umiddelbart og reparasjonssveising er ikke tillatt. (2) Sjekk \u00e5pningsgraden til kroken og mengden slitasje p\u00e5 den farlige delen.<\/p>\n\n\n\n<p>(3) Sjekk om slitasjen p\u00e5 trinsesporet og felgen er jevn, om st\u00e5ltauet passer til rillen, og om trinsen er l\u00f8s eller rister.<\/p>\n\n\n\n<p>(4) S\u00f8rg for at den roterende delen av kroken roterer fritt og at gapet ikke kan v\u00e6re for stort. Hvis det er problemer med rotasjon eller blokkering, sjekk om lagrene eller akselhylsene er skadet eller mangler sm\u00f8ring.<\/p>\n\n\n\n<p>(5) Se etter overbelastningsskader p\u00e5 hovedkroken.<\/p>\n\n\n\n<p>(6) Sjekk delene som krokbeskyttelsesplaten og tverrbjelken. Hvis beskyttelsesplaten er sterkt slitt, kan den sveises og bores p\u00e5 nytt. Hvis du erstatter med nye deler, er det n\u00f8dvendig \u00e5 sikre at de mekaniske egenskapene til materialet oppfyller kravene.<\/p>\n\n\n\n<p>(7) Kontroller anti-frakoblingsanordningen<\/p>","protected":false},"excerpt":{"rendered":"<p>Krankroken er den mest brukte l\u00f8fteanordningen i l\u00f8fteoperasjoner, som b\u00e6rer all last som l\u00f8ftes.
