C80 series gondola car introduction

C80 gondola car, an 80t aluminum alloy gondola car designed and developed by Qiqihar Factory in 2003, is mainly used for heavy-duty transportation of Daqin Railway. In March 2003, the Transportation Bureau of the Ministry of Railways held the "Daqin Railway Transportation Expansion Technology Seminar". At the meeting, the feasibility analysis of the 20000-ton heavy-haul train on the Daqin Railway was discussed and passed, and the conditions for use of the vehicles were determined. And assessment standards. In 2004, the Ministry of Railways Science and Technology Department set up a project to develop and develop "25t axle load low altitude weight ratio special coal gondola car".

2. Model characteristics and technical parameters

C80 gondola is mainly composed of car body, bogie, brake device, hook and buffer device. The reliability design concept is adopted in the design to improve the reliability of key components, thus prolonging the maintenance cycle, reducing the cost, and realizing continuous operation of 1.6 million kilometers without overhaul.

The body is mainly composed of underframe, bathtub, side wall, end wall and strut. For the first time, the vehicle adopts aluminum alloy and polymer non-metallic light new materials, and uses a double bathtub car body. In addition to the underframe, the riveting structure of aluminum alloy profiles and plates is used, which greatly reduces the weight of the vehicle and reduces the center of gravity of the vehicle.

underframe is made of high strength weathering steel with a yield strength of 450Mpa, and the traction beam is reinforced.

brake device adopts the air brake device whose main brake pressure can meet the requirements of 500Kpa and 600Kpa, and the installation position of the ECP wired electric control brake system is reserved.

vehicle is equipped with grade E steel No. 17 interlocking fixed coupler, and the 2-position end is equipped with grade E steel No. 16 interlocking rotating coupler, which can be adapted to continuous tipping and unloading operations without taking off the hook. Supporting E-grade steel tail frame and MT-2 type buffer are adopted. When the drawbar device is used, the three vehicles are set as a group, the vehicles at both ends are respectively used for rotating coupler and fixed coupler, and the middle vehicles are connected by the drawbar device.
