<p>The present invention relates to a caterpillar driving system which prevents a bicycle, a rail sled or a rail bike from skidding on a slope section so that a user can more easily drive the bicycle, the rail sled or the rail bike on the slope section, thereby securing stability. The caterpillar driving system includes a rail on which the bicycle, the rail sled or the rail bike is driven and a slope driving part (300) installed on a slope part of the rail. The slope driving part (300) includes a track part (320), a hooking part (310), and a power part (330). Additionally, the slope driving part includes a wire type track part (321), a gripper type hooking part (360), and the power part (330). The caterpillar driving system also includes the bicycle, the rail sled or the rail bike to be driven on the rail.</p> |
