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

\u200b\"WTL-A100N
\n\u200bWTL-A100N torque limiter<\/strong>It is the basis of micro and special technologyNational standards GB12602-2009 and GB6067.1-2010<\/strong>The new generation of crane safety protection devices developed. It is specially designed for cranes that need to frequently adjust their working conditions. By monitoring key parameters such as weight and Angle in real time, it dynamically calculates the actual moment value. When the load approaches the critical state, the system automatically triggers an audible and visual alarm and cuts off dangerous operations, effectively preventing overloading accidents. Its integrated shockproof structure and high anti-interference feature make it particularly suitable for harsh outdoor working conditions.<\/p>\n
