Na splo\u0161no ga lahko glede na razli\u010dne proizvodne metode razdelimo na kovane kljuke in laminirane kljuke. Glede na razli\u010dne oblike jih lahko razdelimo na enojne in dvojne kavlje.<\/p>\n\n\n\n<p>Danes bomo predstavili dve najpogostej\u0161i vrsti:<\/p>\n\n\n\n<p>(1) Kavelj za rezine<\/p>\n\n\n\n<p>Trnke za rezine delimo na enojne in dvojne. Ta vrsta kljuke ima preprosto strukturo, zanesljivo delovanje in priro\u010dno vzdr\u017eevanje. Enojni kavlji se obi\u010dajno uporabljajo na livarskih \u017eerjavih, medtem ko se dvojni kavlji obi\u010dajno uporabljajo v \u017eerjavih za splo\u0161no uporabo, ki tehtajo ve\u010d kot 100 ton.<\/p>\n\n\n\n<p>(2) Kovani kavelj<\/p>\n\n\n\n<p>Kovani trnki se delijo na enojne in dvojne. Ker lahko sila na enojni kavelj odstopa, ni tako stabilna kot simetri\u010dna sila na dvojnem kavlju. Zato majhna in srednje velika \u017eerjava s te\u017eo manj kot 75 ton pogosto uporabljajo en kavelj. \u017derjavi z nosilnostjo nad 75 ton pogosto uporabljajo dvojne kljuke.<\/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=\"kljuke \u017eerjava\" 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=\"kljuke \u017eerjava\" 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 Kako dobro opraviti vsakodnevno vzdr\u017eevanje kavljev?<\/p>\n\n\n\n<p>Varnost in stabilnost trnkov imata pomembno vlogo pri varni proizvodnji. Enota, ki jo uporablja, mora redno izvajati dnevne varnostne preglede in vzdr\u017eevanje kljuke. Na splo\u0161no dnevni pregled in vzdr\u017eevanje kavljev vklju\u010duje naslednje:<\/p>\n\n\n\n<p>(1) O\u010distite glavno telo <a href=\"https:\/\/www.sevencrane.com\/sl\/product\/crane-hook\/\">kavelj \u017eerjava<\/a> sklop z nejedkim organskim topilom, ga obri\u0161ite do suhega in preglejte s pove\u010devalnim steklom. \u010ce se odkrijejo razpoke, jih je treba takoj zamenjati, popravljalno varjenje pa ni dovoljeno. (2) Preverite stopnjo odpiranja kljuke in stopnjo obrabe na nevarnem delu.<\/p>\n\n\n\n<p>(3) Preverite, ali je obraba utora in roba jermenice enakomerna, ali se jeklena \u017ei\u010dna vrv ujema z utorom in ali je jermenica ohlapna ali se trese.<\/p>\n\n\n\n<p>(4) Prepri\u010dajte se, da se vrtljivi del kavlja prosto vrti in da razmak ne sme biti prevelik. \u010ce pride do te\u017eav pri vrtenju ali zagozdenju, preverite, ali so le\u017eaji ali pu\u0161e gredi po\u0161kodovane ali premalo mazane.<\/p>\n\n\n\n<p>(5) Preverite, ali je glavni kavelj po\u0161kodovan zaradi obremenitve.<\/p>\n\n\n\n<p>(6) Preverite dele, kot sta za\u0161\u010ditna plo\u0161\u010da kljuke in pre\u010dni nosilec. \u010ce je za\u0161\u010ditna plo\u0161\u010da mo\u010dno obrabljena, jo lahko privarite in ponovno izvrtate.
