Frenos de emergencia de seguridad hidr\u00e1ulicos<\/strong><\/span><\/h6>\n

Los frenos de seguridad para gr\u00faas de la serie SB son dispositivos de frenado de alta potencia dise\u00f1ados para ejes de baja velocidad (ejes de tambor). Estos frenos son ampliamente adecuados para el frenado de seguridad de emergencia en gr\u00faas medianas y grandes, ascensores de maquinaria de manipulaci\u00f3n portuaria y ejes de baja velocidad de mecanismos de inclinaci\u00f3n de pluma. Tambi\u00e9n son ideales para el frenado de seguridad operativo y de emergencia de polipastos mineros, equipos de elevaci\u00f3n y transportadores de cinta inclinados de gran potencia, as\u00ed como para el frenado de seguridad en mecanismos de accionamiento de telef\u00e9ricos y gr\u00faas de cable. Adem\u00e1s, proporcionan frenado de emergencia para los ejes de baja velocidad de mecanismos de elevaci\u00f3n en aplicaciones especiales de elevaci\u00f3n, como gr\u00faas de fundici\u00f3n.<\/p>\n

Caracter\u00edsticas principales de la gr\u00faa Frenos de seguridad<\/a><\/strong><\/span><\/h6>\n
    \n
  • Con un dise\u00f1o normalmente cerrado, estos frenos son seguros y fiables. La fuerza de frenado se aplica mediante un muelle de disco especialmente dise\u00f1ado, mientras que la energ\u00eda hidr\u00e1ulica libera el freno (consulte el cat\u00e1logo de estaciones hidr\u00e1ulicas para la selecci\u00f3n de estaciones hidr\u00e1ulicas).<\/li>\n
  • Equipados con pastillas de fricci\u00f3n dura de alto rendimiento y sin amianto, ofrecen un coeficiente de fricci\u00f3n estable sin da\u00f1ar el disco de freno y son resistentes al agua y a la niebla salina (espuma de mar).<\/li>\n
  • Los frenos son muy sensibles, con tiempos de cierre (frenado) cortos.<\/li>\n
  • Se dispone de interruptores opcionales, como el l\u00edmite de desbloqueo y el l\u00edmite de desgaste de las pastillas, para la visualizaci\u00f3n de se\u00f1ales o la protecci\u00f3n de enclavamiento.<\/li>\n
  • Una estructura de sellado bien dise\u00f1ada y juntas importadas de primera calidad proporcionan un sellado eficaz y una larga vida \u00fatil.<\/li>\n
  • Las flexibles opciones de instalaci\u00f3n hacen que los frenos sean f\u00e1ciles de usar, ajustar y mantener.<\/li>\n<\/ul>\n
    Condiciones de funcionamiento de los frenos de seguridad de las gr\u00faas<\/strong><\/span><\/h6>\n
