S\u00e9lectionner la mauvaise bo\u00eete d'alimentation de frein ou le redresseur peut causer de graves probl\u00e8mes de fiabilit\u00e9 et de s\u00e9curit\u00e9 sur les grues. Si la tension de sortie CC ne correspond pas \u00e0 la bobine de frein, le frein peut se lib\u00e9rer lentement, ne pas se lib\u00e9rer compl\u00e8tement (traction), ou surchauffer la bobine et r\u00e9duire sa dur\u00e9e de vie. Un redressement incorrect ou une suppression de surtension manquante peut entra\u00eener des bourdonnements, un engagement instable, des dommages au contacteur ou des d\u00e9faillances r\u00e9p\u00e9t\u00e9es de la bobine.<\/p>
De nombreux freins de grues industrielles b\u00e9n\u00e9ficient de caract\u00e9ristiques de \u00ab lib\u00e9ration rapide \u00bb (courant d'appel plus \u00e9lev\u00e9 ou rectification optimis\u00e9e) pour r\u00e9duire le d\u00e9lai d'engagement et minimiser l'usure. Si l'alimentation ne peut pas fournir le bon comportement de lib\u00e9ration, la grue peut conna\u00eetre des d\u00e9marrages saccad\u00e9s, un retard dans l'ouverture du frein, un courant moteur plus \u00e9lev\u00e9 et une surchauffe des surfaces de friction. Assurez-vous toujours que la tension d'entr\u00e9e, la sortie CC, le cycle de service et la classification environnementale (IP, temp\u00e9rature) correspondent \u00e0 la conception du frein. En cas de doute, choisissez des alimentations recommand\u00e9es par le fabricant pour maintenir la performance de s\u00e9curit\u00e9 du frein et la conformit\u00e9.<\/p>","protected":false},"excerpt":{"rendered":"
Selecting the wrong brake power supply box or rectifier can cause serious reliability and safety problems on cranes. If the DC output voltage does not match the brake coil, the brake may release slowly, fail to release fully (dragging), or overheat the coil and shorten its life. Incorrect rectification or missing surge suppression can lead […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[132,3],"tags":[133],"class_list":["post-2375","post","type-post","status-publish","format-standard","hentry","category-faq","category-blog","tag-overhead-or-gantry-crane"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.takebrakes.com\/fr\/wp-json\/wp\/v2\/posts\/2375","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.takebrakes.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.takebrakes.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.takebrakes.com\/fr\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.takebrakes.com\/fr\/wp-json\/wp\/v2\/comments?post=2375"}],"version-history":[{"count":1,"href":"https:\/\/www.takebrakes.com\/fr\/wp-json\/wp\/v2\/posts\/2375\/revisions"}],"predecessor-version":[{"id":2390,"href":"https:\/\/www.takebrakes.com\/fr\/wp-json\/wp\/v2\/posts\/2375\/revisions\/2390"}],"wp:attachment":[{"href":"https:\/\/www.takebrakes.com\/fr\/wp-json\/wp\/v2\/media?parent=2375"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.takebrakes.com\/fr\/wp-json\/wp\/v2\/categories?post=2375"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.takebrakes.com\/fr\/wp-json\/wp\/v2\/tags?post=2375"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
