Mine shaft sinking winch braking performance: the brake job should be sensitive and reliable, the contact area between the brake shoe (with) the rim and the brake shall be not less than 70%. Safe brake air travel time: compressed air brake brake shoe should not exceed 0.5s; brake shoe brake hydraulic accumulator should not exceed 0.6s.
