The invention relates to a double-wheel self-propelled rope carrier. Two sets of traveling wheel assemblies (2), a friction clutch assembly (3), two sets of main rope supporting wheel assemblies (4), a connecting rod mechanism assembly (5), a sprocket device assembly (6), a traction rope pinch roller assembly (7), a friction wheel assembly (10) and a lifting rope supporting wheel assembly (12) are arranged on a rack (8). According to the double-wheel self-propelled rope carrier provided by the invention, the problems of span and safety can be solved very well; the service life of a main rope can be prolonged; the use requirement on the large span (the span of a rope crane can reach 1,400m) can be met; the double-wheel self-propelled rope carrier is safe and reliable; the operation speed of a trolley is high; the operation maintenance cost is low; and the production rate can be greatly improved.
