Why the braking system is so important in public works and mining machinery?
To start with, the braking system is responsible for stopping and reducing the movement of a machine. When used in public works and mining machinery, it is a basic element to guarantee the vehicle´s security at all times. Thus, in the event of a technical fault, we need to know if error is due to the brake system and, how to carry out a quick maintenance.
The braking system works by means of friction. It triggers when the Kinetic energy is being produced using the heat caused by the movement´s friction.
The different braking systems in the public works machinery and mining industry are:
Hydraulic braking system:
This system applies pressure on the brake shoes and forces them out and against the drums.
Band braking system:
This system uses some type of band placed around a pulley to slow and eventually stop its rotation. It is very common on caterpillars.
Wet, slow rotating multi disc brakes:
This type of braking is immersed in oil to avoid overheating (which can cause brake fade). It is mounted right in the differential of the vehicle. The multiple discs in wet brakes are the key to stopping power in even the heaviest machineries.
Drum Braking:
Known for the pressure of a pair of brake shoes connected to the wheel. Nowadays, are less frequent.
Eddy current braking (Electromagnetic brakes):
Its mechanics avoid friction amongst its components. An Eddy current is an inverse response to the magnetic field that reacts between forces braking and/or reducing the speed of the machine.
An optimal brake system allows the operator a major control of the heavy machinery during the driving, enhancing ride control. Furthermore, it will bring safety to the driver and workers around, ensuring the vehicle will stop as and when necessary.
