The reason that the mining locomotive have poor brake ability as below:
① The brake shoes are seriously worn, the remaining thickness is less than 10 mm, and there is no guarantee that the brake pads and the rim maintain a gap of 2 to 3 mm.
② The wear of the screw, nut, pin and hole of the brake system exceeds the limit.
③The balance beam and boom of the braking system are generated due to external force
Deformation, poor brake shoe contact during braking.
④ The 1.9K W motor and the air compressor do not work, and the contact of the electric contact pressure gauge is poor, Malfunction of foot valve and trachea.
⑤ Failure to follow the locomotive regulations, the load is severely overloaded.
The above is the reason for the poor braking capacity of the electric locomotive.
