Como Funcionam os Trav\u00f5es de Tambor S\u00e9rie YWZ4<\/h2>\n\n\n\n

The YWZ4 series operates on a proven spring-applied, hydraulic-release<\/strong> principle that ensures fail-safe performance in critical lifting applications.<\/p>\n\n\n\n

Fase de Travagem (Desligado)<\/h3>\n\n\n\n

When electrical power is disconnected or the thruster is de-energized, powerful compression springs<\/strong> force the brake arms to pivot, pressing the brake pads firmly against the rotating brake wheel. The resulting friction generates the rated braking torque, securely holding the load in position.<\/p>\n\n\n\n

Fase de Libera\u00e7\u00e3o (Ligado)<\/h3>\n\n\n\n

Quando o propulsor recebe energia, o motor interno aciona uma bomba hidr\u00e1ulica que estende a haste do propulsor, superando a for\u00e7a da mola e libertando as pastilhas de trav\u00e3o da roda de trav\u00e3o. O sistema hidr\u00e1ulico proporciona uma a\u00e7\u00e3o de liberta\u00e7\u00e3o suave e controlada que minimiza o choque mec\u00e2nico no sistema de accionamento.<\/p>\n\n\n\n
