\u200b1. Product Introduction<\/strong><\/h3>\n

\"WTL-A710
\n\u200bWTL-A710 Hydraulic torque limiter<\/strong>It is an intelligent safety system tailor-made for wheeled cranes (such as truck cranes, tire cranes, etc.). \"ThroughReal-time monitoring of hydraulic pipeline pressure<\/strong>Based on the data of the boom Angle and length, the working moment value is dynamically calculated. When the load approaches the critical value, the system automatically triggers an audible and visual alarm and cuts off dangerous operations, completely eliminating the risk of overloading and overturning of the hydraulic power take-off crane.<\/p>\n

\u200b2. Main functions<\/strong>\u200b<\/h3>\n

\u200bDual core of hydraulic perception and intelligent protection<\/strong>\u200b<\/p>\n

    \n
  • \u200bFive-channel oil pressure precise monitoring<\/strong>\u200b
    \nSynchronous monitoring of the main hook\/auxiliary hook lifting oil circuit, luffing cylinder, rotary motor and hoisting system<\/li>\n
