China's first high-speed rail lifting "Hercules" to fill the gap

It was learned from China’s Qiqihar Transportation Equipment Co., Ltd. that on June 26, the 125-ton high-speed railway crane with complete independent intellectual property rights developed by the company successfully passed the on-site simulation drill in Taiyuan. This is the "first show" of the car after being reviewed by the China National Railway Corporation on June 16. It marks the first domestic and world-leading high-speed railway crane to come out and fills the gap in China's high-speed rail emergency support equipment.

Due to the inability of similar foreign products to be used on bridges and high-speed railways in China, in order to maintain the operational safety of high-speed rails and timely and effectively dispose of various types of emergencies related to the operation of high-speed rails, the China National Railway Corporation established a special railway crane for high-speed rail in 2013. CSR Qiqihar Transportation Equipment Co., Ltd. draws on the design, manufacturing and application experience and advanced technologies of domestic and international large-scale 100t, 125t, and 160t railway cranes, and combines domestic high-speed rail and ordinary lines, bridges, and special working conditions to achieve independent innovation. In conjunction with the Institute of Rail Transit, Institute of Railway Science and Technology, Southwest Jiaotong University, Dalian Jiaotong University, Dalian University of Technology, etc., the development of high-speed railway dedicated railway cranes and jib cranes was started.

The maximum capacity of the high-speed railway crane is 125t, and the maximum lifting torque of the high-speed rail line is 1125t·m (45t lifting capacity and 25m in width). It is based on the high-speed railway and takes into consideration the emergency protection of ordinary line vehicles to meet the single- and double-line high-speed railway bridges. Tunnels, curves, ramps, and operations under a variety of operating conditions under the catenary can be used to directly drive complex vehicle groups on high-speed railway bridges, as well as large-scale cargo handling, heavy equipment installation, etc. It is both high-speed rail-specific and widely adaptable. Sex.

At 15 o'clock on the June 26th, a new Chinese car maker, "Hercules," slowly entered the "examination room" at the Taiyuan Railway Bureau. Under the moderator's explanation, this "Hercules" elegantly and perfectly demonstrates the three key high-speed rail emergency handling conditions. It showed many key technologies such as innovative multi-legs, shared bearing of wheel pairs, and innovative auxiliary wheel support, and delivered a perfect “test paper”.

According to reports, this "Hercules" compared with similar foreign products, using a multi-legged bearing and support leg load intelligent control and other key technologies to solve the problem of high-speed railway lines and bridges bearing capacity constraints; the use of auxiliary support, It can realize the free-walking operation of the crane lifting heavy objects on the bridge; adopts advanced technologies and structures such as arc-shaped boom, swing-type telescopic heavy-duty iron, four-axis welded bogie, and telescopic outrigger, which reduces the weight and satisfies the high-speed rail The requirements for high-speed loopback and safe and efficient operation of cranes; the first intelligent fault diagnosis system was adopted, which fully improved the reliability and operability, and achieved the goal of safe, efficient, and intelligent control of high-speed rail emergency protection.
