The present invention relates to an electric tracklaying gear and the use thereof for a self-propelled working machine, preferably for a construction or earth-moving machine or a surface mining machine such as Surface Miner, which includes an endlessly circulating track chain which can be driven by a crawler drive that is arranged inside the path of circulation of the track chain. It is proposed to associate a cooling device with a closed fluid cooling circuit to the electric motor of the crawler drive arranged in the interior of the path of circulation of the track chain. Due to the high thermal capacity of a suitable cooling fluid such as oil or water-glycol mixture small volumetric flow rates in the fluid cooling circuit and hence small conduit cross-sections are sufficient. On the other hand, due to the closed formation of the fluid cooling circuit any dust input into the crawler drive and also any generation of dust by exhaust air can be avoided.
