1. Product Introduction<\/h3>\n

\"WTL-A200\u200b<\/p>\n

\u200bThe WTL-A200 Moment Limiter<\/strong>is the intelligent safety control core for cranes by WTAU Electronics,validated in the market for 15 years.<\/strong>It features a 240\u00d7128 large blue LCD screen that dynamically refreshes key parameters in real time, including main hook load, jib amplitude and load rate. When the load rate is exceeded, the screen immediately turns red and triggers a buzzer alarm of over 60dB, providing national standard-level overload protection for mobile cranes, port gantry cranes and other equipment.<\/p>\n
