Han Bo, member of the Standing Committee and Deputy Secretary of the Shaoshan Municipal Party Commit

  On May 25th,to welcome the first National Science and Technology Workers Day in Shaoshan City,Han Bo,member and deputy secretary of the Shaoshan Municipal Party Committee,and Zhang Xiaoling,vice chairman of the Shaoshan Municipal Political Consultative Conference and chairman of the Science and Technology Association,visited and comforted our company's scientific research staff at Xiangtan Hengxin.
  Vice Secretary Han visited the company's honor exhibition room and production workshop with Ouyang Yang,Deputy Director of the Engineering Technology Research Center for Underground Passenger Equipment in Hunan Province and Chief Engineer of Xiangtan Hengxin.He also had exchanges with scientific research and technical staff to gain a deeper understanding of their work and living conditions,and offered them holiday condolences,And praise and affirm the achievements of Xiangtan Hengxin in scientific research and technological achievements!
  Established in 1999,Xiangtan Hengxin is a large-scale research and manufacturing enterprise for underground passenger equipment in mines.We have the only provincial-level"Mine Underground Passenger Equipment Engineering Technology Research Center"and"Provincial Enterprise Technology Research Center"in China.The center has more than 50 research experts and technical personnel,constantly leading the industry's technological progress and product innovation.Has won honors such as the National Invention and Entrepreneurship Award,National Science and Technology Progress Award Excellence Award,National Invention Exhibition Invention Silver Award,and Hunan Province Science and Technology Progress Third Prize.

  Xiangtan Hengxin Product Technology
  ★ Aerial passenger device
  The hydraulic drive system for the aerial passenger device (commonly known as the "hydraulic monkey car") has passed the scientific and technological appraisal of the Hunan Provincial Department of Science and Technology,   and the conclusion is to fill the domestic gap and achieve the international advanced level in technology. Listed as a key transformation project for scientific and technological achievements by the Ministry of Industry and     Information Technology of China, and promoted for application.
  Received the 7th National Invention and Entrepreneurship Award.
  Pioneered in the development and application of axle breakage protection technology for overhead passenger devices, and has obtained an invention patent.
  We have taken the lead in developing online monitoring and alarm protection technology for steel wire ropes used in overhead passenger devices. When the broken wire of the steel wire rope reaches the scrap standard (10%)   specified in the Coal Mine Safety Regulations, the overhead passenger device cannot be started and operated.
  The hydraulic station for the wheel brake is equipped with a dual pump and dual motor system, achieving one in use and one backup.
  Equipped with oil change reminder function
  Equipped with mandatory routine inspection function
  Traction wire rope braking function
  Wireless emergency stop function throughout the tunnel
  ★ Endless rope continuous tractor
  Passive braking technology for shuttle cars: When the shuttle car exceeds the speed limit severely, the shuttle car will automatically perform track holding braking, and the main motor will automatically stop to ensure safety.
  Detection and alarm parking technology for steel wire rope falling off the slope at the current slope change point: When the steel wire rope falls off the slope at the current slope change point, the motor automatically loses   power and stops.
  Slope change point anti detachment rope technology: can effectively prevent the steel wire rope from falling off the track at the downhill slope change point.
  ★ Rope traction track type overhead passenger device
  The only revolutionary technological product in the industry, abbreviated as "Rail Monkey Car". It has the advantages of not falling off the road, not speeding, and turning freely on large slopes. Compared with traditional     overhead passenger devices, it has higher safety performance and stronger adaptability to underground tunnel conditions.
  ★ The electrical control device adopts a dual PLC system
  Dual protection circuit, achieving one backup and one use. The control panel adopts LCD touch screen control, and can achieve remote information control function according to user requirements.
  ★ Wireless mobile video monitoring technology
  Used for real-time video monitoring throughout the entire area of the tunnel.
  ★ Information based intelligent control technology
  Undertaken the construction project of the IoT supervision platform for mining products by the National Coal Supervision Administration and the Safety Standards Office (part of the overhead passenger device).
