How many tons of weight can be hauled by a 3 ton mining motor car?

The motor power of 3 tons motor car is 6.5kwx2, which is a wire motor car, and it can haul about 30 tons of goods when the slope is about 3‰ (including the self weight of the locomotive and the self weight of the mine car.)

If it is a 3-ton battery motor car, the motor power is 4.5kw, and it can haul about 25-30 tons of goods when the slope is about 3‰ (including the weight of the locomotive and the weight of the mine car.)

Of course, if the slope exceeds 3‰, the traction force will be reduced, and the specific situation is different according to the mining environment.
