Le SeeZol\u00a0Syst\u00e8me d'indicateur de moment de charge de grue (LMI pour grues)<\/strong><\/a> \u00e9galement connu sous le nom de Grue<\/strong> Indicateur de charge de s\u00e9curit\u00e9 (SLI)<\/strong><\/a> Il s'agit d'un dispositif essentiel qui assure le fonctionnement s\u00fbr des \u00e9quipements. Ses param\u00e8tres techniques ont un impact direct sur la pr\u00e9cision et la fiabilit\u00e9 de la protection. Voici les principales sp\u00e9cifications et descriptions fonctionnelles d'un syst\u00e8me type\u00a0:<\/p>\n\n\n\n

1. Plage de surveillance des moments<\/strong><\/strong><\/p>\n\n\n\n

Moment nominal : couvre g\u00e9n\u00e9ralement 50 % \u00e0 150 % de la charge nominale de la grue (par exemple, 50 \u00e0 300 kN\u00b7m), prenant en charge l'\u00e9talonnage dynamique.<\/p>\n\n\n\n

Classe de pr\u00e9cision : \u00b1 3 % FS (pleine \u00e9chelle), avec des mod\u00e8les de haute pr\u00e9cision atteignant \u00b1 1 % (utilisant des jauges de contrainte et une technologie de filtrage num\u00e9rique).<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

\u200b2. Seuils de protection \u00e0 plusieurs niveaux<\/strong><\/p>\n\n\n\n

Seuil d'avertissement : fix\u00e9 \u00e0 90 % du moment nominal (alarme sonore\/visuelle).<\/p>\n\n\n\n

Protection primaire : \u00c0 105 %, la r\u00e9duction automatique de la vitesse est d\u00e9clench\u00e9e.<\/p>\n\n\n\n

Protection secondaire : \u00c0 110 %, la puissance de levage est coup\u00e9e et le freinage m\u00e9canique est activ\u00e9.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

\u200b3. Temps de r\u00e9ponse<\/strong><\/p>\n\n\n\n

\u2264 50 ms entre la surcharge instantan\u00e9e et l'action de protection (bas\u00e9e sur un PLC ou des contr\u00f4leurs d\u00e9di\u00e9s).<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

\u200b4. Configuration du capteur<\/strong><\/p>\n\n\n\n

Capteurs de contrainte : install\u00e9s \u00e0 la racine de la fl\u00e8che, avec une r\u00e9sistance aux chocs \u2265 50 g.<\/p>\n\n\n\n

Capteurs d'angle : Surveillance en temps r\u00e9el de l'angle d'\u00e9l\u00e9vation de la fl\u00e8che (pr\u00e9cision de \u00b1 0,1\u00b0) pour la compensation du calcul du moment.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

\u200b5. Adaptabilit\u00e9 environnementale<\/strong><\/p>\n\n\n\n

Temp\u00e9rature de fonctionnement : -30\u00b0C \u00e0 +70\u00b0C (indice de protection IP65), avec r\u00e9sistance EMI (conforme \u00e0 la norme EN 61000-6-2).<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

\u200b6. Interfaces de donn\u00e9es<\/strong><\/p>\n\n\n\n

Bus RS485\/CAN standard, prenant en charge la surveillance \u00e0 distance (compatible avec le protocole ISO 2386).<\/p>\n\n\n\n
