Globalement, selon diff\u00e9rentes m\u00e9thodes de fabrication, il peut \u00eatre divis\u00e9 en crochets forg\u00e9s et crochets lamin\u00e9s. Selon leurs diff\u00e9rentes formes, ils peuvent \u00eatre divis\u00e9s en crochets simples et crochets doubles.<\/p>\n\n\n\n<p>Aujourd&#039;hui, nous pr\u00e9senterons les deux types les plus courants\u00a0:<\/p>\n\n\n\n<p>(1) Crochet \u00e0 trancher<\/p>\n\n\n\n<p>Les crochets tranches sont divis\u00e9s en crochets simples et crochets doubles. Ce type de crochet a une structure simple, un fonctionnement fiable et un entretien pratique. Les crochets simples sont couramment utilis\u00e9s sur les grues de coul\u00e9e, tandis que les crochets doubles sont couramment utilis\u00e9s dans les grues \u00e0 usage g\u00e9n\u00e9ral pesant plus de 100 tonnes.<\/p>\n\n\n\n<p>(2) Crochet forg\u00e9<\/p>\n\n\n\n<p>Les crochets forg\u00e9s sont divis\u00e9s en crochets simples et crochets doubles. \u00c9tant donn\u00e9 que la force exerc\u00e9e sur un crochet simple peut varier, elle n\u2019est pas aussi stable que la force sym\u00e9trique exerc\u00e9e sur un crochet double. Par cons\u00e9quent, les grues de petite et moyenne taille pesant moins de 75 tonnes utilisent souvent un seul crochet. Les grues d&#039;un tonnage sup\u00e9rieur \u00e0 75 tonnes utilisent souvent des crochets doubles.<\/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=\"crochets de grue\" 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=\"crochets de grue\" 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 Comment faire un bon travail d&#039;entretien quotidien des crochets ?<\/p>\n\n\n\n<p>La s\u00e9curit\u00e9 et la stabilit\u00e9 des crochets jouent un r\u00f4le important dans une production s\u00fbre. L&#039;unit\u00e9 utilisatrice doit effectuer r\u00e9guli\u00e8rement des inspections de s\u00e9curit\u00e9 et un entretien quotidiens sur le crochet. De mani\u00e8re g\u00e9n\u00e9rale, l&#039;inspection et l&#039;entretien quotidiens des crochets comprennent les \u00e9l\u00e9ments suivants\u00a0:<\/p>\n\n\n\n<p>(1) Nettoyez le corps principal du <a href=\"https:\/\/www.sevencrane.com\/fr\/product\/crane-hook\/\">crochet de grue<\/a> l&#039;ensemble avec un solvant organique non corrosif, essuyez-le et inspectez-le avec une loupe. Si des fissures sont d\u00e9tect\u00e9es, elles doivent \u00eatre remplac\u00e9es imm\u00e9diatement et les r\u00e9parations par soudage ne sont pas autoris\u00e9es. (2) V\u00e9rifiez le degr\u00e9 d&#039;ouverture du crochet et le degr\u00e9 d&#039;usure de la section dangereuse.<\/p>\n\n\n\n<p>(3) V\u00e9rifiez si l&#039;usure de la rainure et de la jante de la poulie est uniforme, si le c\u00e2ble en acier correspond \u00e0 la rainure et si la poulie est desserr\u00e9e ou tremble.<\/p>\n\n\n\n<p>(4) Assurez-vous que la partie rotative du crochet tourne librement et que l&#039;espace ne peut pas \u00eatre trop grand. En cas de difficult\u00e9s de rotation ou de blocage, v\u00e9rifiez si les roulements ou les manchons d&#039;arbre sont endommag\u00e9s ou manquent de lubrification.<\/p>\n\n\n\n<p>(5) V\u00e9rifiez que le crochet principal n&#039;est pas endommag\u00e9 par une surcharge.<\/p>\n\n\n\n<p>(6) V\u00e9rifiez les pi\u00e8ces telles que la plaque de protection du crochet et la traverse. Si la plaque de protection est tr\u00e8s us\u00e9e, elle peut \u00eatre soud\u00e9e et reperc\u00e9e. En cas de remplacement par des pi\u00e8ces neuves, il est n\u00e9cessaire de s&#039;assurer que les propri\u00e9t\u00e9s m\u00e9caniques du mat\u00e9riau r\u00e9pondent aux exigences.<\/p>\n\n\n\n<p>(7) V\u00e9rifier le dispositif anti-d\u00e9couplage<\/p>","protected":false},"excerpt":{"rendered":"<p>Le crochet de grue est l\u2019appareil de levage le plus couramment utilis\u00e9 dans les op\u00e9rations de levage, car il supporte toute la charge soulev\u00e9e.
