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

\"WTL-A220\u200b
\n\u200bWTL-A220 torque limiter<\/strong>is aIntelligent safety hub for tower cranes<\/strong>(Won the Major Scientific and Technological Achievement Award of Hubei Province) Designed specifically for tower cranes, it builds a millisecond-level safety protection closed loop by real-time monitoring of six parameters including lifting weight, amplitude, height, orientation and wind speed. Its split structure design supports 3-limit \/ 6-limit custom configuration and integration simultaneouslyBlack box record<\/strong>with4G remote transmission<\/strong>Dual-core function.<\/p>\n
