Abstract: Abstract: In order to effectively solve the problem of large slope traction of track miner in coal mine, the design technical requirement of the rubber wheel tractor were obtained through the study of the operating environment conditions of the underground track miner. And through the matching calculation of the key technical power system of the vehicle and the research of the swing compensation traction device, the overall arrangement scheme of the tractor is designed. Finally, the first tractor completed production, and has carried on the underground industrial test, the result shows that this scheme has effectively solved the traction problem of the track harvesters.
