What is the mechanical brake of the 8-ton underground mining locomotive?

Strictly speaking, there are only two types of braking methods for 8-ton underground mining locomotives, mechanical braking and electrical braking, and the latter is generally used as an auxiliary braking method. The main difference between the two lies in the braking principle. Mechanical braking ultimately uses friction braking, such as the friction between the brake shoe and the wheel, while electrical braking is braking by controlling the direct motor.

Then mechanical brakes are mainly divided into pure mechanical brakes, hydraulic brakes and compressed air brakes. The difference between the three is the source of the braking force. The braking force of pure mechanical braking comes from human power, which is amplified by worm gear and worm, so that the brake shoe tightly fits the wheel to generate braking. The braking force of hydraulic braking and air braking obviously comes from hydraulic pressure and compressed air, respectively, and then makes the brake shoe fit with the wheel or flywheel.

Because the sources of braking force are different, many times in order to be "lazy", we directly replace pure mechanical braking with mechanical braking, and regard the three mechanical braking methods as "three types" braking methods.
