The utility model relates to a slope climbing automatic anti-reverse slipping system of an electric wheel off-highway dumper, and the system belongs to the field of the intelligent control of off-highway dumpers. A control system acquires the gradient of a slope from an inclinator and the load of an electric wheel mining truck from a weighing system, so as to calculate the safety moment F0 to prevent the electric wheel mining truck from reversely slipping when a brake is released so as to control a moment controller to keep increasing the moment F on a wheel motor; and when F is more than F0, the brake is loosened to realize the stable slope climbing. Due to the adoption of the system, a driver can realize the automatic anti-reverse slipping take-off of the electric wheel mining truck on the slope only by using an accelerator panel without also using a working brake pedal.
