Comparison Between Mechanical Braking and Electrical Braking
Sr. No. | Mechanical Braking | Electrical Braking |
---|---|---|
1. | Mechanical braking produces excessive wear and tear of brake block shoes of brake lining. Therefore, frquent replacement is necessary. | No such need |
2. | Due to constant wear and tear of brake lining frquent adjustments are necessary to compensate the offset error, therefore maintanace is costly | Less maintanace |
3. | Produce metal dust causing wearing of bearings. | No such a dust is formed |
4. | If they are not correctly adjusted the sudden braking action produce shock, this result in discomfort to passengers | Adjustment is easy and braking action is gradual and smooth. |
5. | Heat is produce in brake shoes of brake lining, which may damage the lining and may result in failure of braking system. | Heat is produce at a convenient place which is no way harmful to braking system. |
6. | No such possibility | 60 to 80 % kinetic energy of apparatus can be fedback to line in regenerative brake. |
7. | Mechanical braking alone can be used | Electrical braking is alone not sufficient, it is to be supplement by mechanical braking. |
8. | Low cost | High initial cost |
