Aiming at large fluctuation of coal seam inclined slope, long distance and other outstanding problems, "KWGP -120 (110,90) / 600 (900) J high-speed standard rail trapped rail transport with large powerful traction " series of products were developed, through improving the winch, traction storage rope braking vehicle, tensioning device structure. The design was conducted in mine auxiliary slope of coal seam. It showed that the main components of system structure design was reasonable, with the advanced configuration, better solved the auxiliary transport problems of large equipment under the complex mine conditions.
