Since 2014, Henan Mining has carefully manufactured 71 sets of lifting equipment for Baosteel Zhanjiang Steel Cold Rolling 2030 Project and 1550 Project. Among them, all 15 cranes in the post rolling warehouse and finished product storage area adopt unmanned new technology, which can achieve functions such as three-dimensional positioning of cranes, automatic searching and loading and unloading, and is also an important component of Baosteel's WMS (warehouse management system). In 2016, it was awarded the title of "Excellent Supplier" by Baosteel Group. The construction and operation concept of "simplicity, efficiency, low cost, and high quality" in the Baosteel Zhanjiang Iron and Steel Three High Furnace System project, as well as the new standard of ultra-low emissions throughout the entire process, have put forward high requirements for the energy-saving and efficient operation of lifting equipment. Our company has carried out tailor-made optimization design for this and has once again deepened cooperation with Baosteel Group Zhanjiang Iron and Steel, signing contracts for 9 double beam bridge cranes for the three cold rolling projects.
