Description

Technical Field

[0001] The utility model relates to the technical field of rail electric traction vehicles, in particular to an electric rail traction vehicle. Background Art

[0002] A rail electric tractor is a type of transport power equipment used on rails, which is used to transport and tow rail transport carriages or other rail transport equipment. Currently, most rail electric tractors are large-scale traction equipment, such as the locomotives that we traditionally understand. Whether they are electrically driven or driven by internal combustion engines, they are usually powered by huge power equipment to achieve the traction of multiple carriages to meet the needs of heavy-load traction. However, for the production environment of some rail equipment, or during the installation stage of rail facilities, small rail equipment is in the greatest demand.

[0003] During the production of track equipment or the installation of track facilities, due to environmental reasons, there will be debris such as small stones or fine welding slag on the track. These debris and garbage will affect the safety of the tractor operation and cause safety accidents such as derailment.

[0004] To this end, we propose an electric rail tractor. Utility Model Content
