In order to implement the requirements of the National Bureau of Quality and Technical Supervision, large-tonnage bridge cranes and portal cranes must be equipped with safety monitoring systems. Since year 2014, HXME has successively upgraded a number of old products and newly-produced products for adding this function. This function enables real-time monitoring of all links and important safety status of the crane's entire control system operation. At the same time, driven by the digital economy and intelligent manufacturing, HXME has independently developed its own IoT (Intenet of Things) platform, which can remotely monitor and diagnose all the products in production, monitor the operation status of the product in real time, and make analysis based on historical data to make early warning for maintenance. The self-developed IoT intelligent control system is at the forefront of the industry and is at the leading level in technological innovation and research and development.
