The forklift brake cable is a flexible cable used to transmit mechanical force by movement of the inner cable (commonly a steel cable) in relation to the hollow outer cable housing. By stepping on the brake pedals, the linear movement is then transmitted into a pulling force by the brake cables. This pulling force directs the hydraulic functions of the master cylinder, which then sends out its hydraulic pressure onto the brake lines all the way to both of the wheel cylinders. The wheel cylinder uses mechanical force to press the brake shoes parallel to the brake drums to generate friction in order to stop or slow down the movement of the wheels.
Failure to control the braking of the forklift can lead to serious injuries and damage to men and material. In the worst-case scenario, one may collide with other pedestrians due to malfunction of the brakes. Hence, all forklifts are served with a reliable braking system to prevent any untoward scene. The braking system applied in the forklift is drum brake system, in which the brake cables play the pivotal role.
Conventionally, there are two types of braking systems: disc brakes and drum brakes. Disk brakes serve to put the moving machine to an almost immediate halt, the drum brakes system, in comparison, works progressively in a steady manner. Application of disk brakes might need some considerable expertise / experience, as a sudden halt of a moving automobile, especially a two-wheeler, can cause some serious accidents. Drum brake system being progressive and comparatively risk free, is more popular of the two options. Disk brake system utilizes brake pads instead of brake shoes. The brake pads actually convert the kinetic energy of the forklift truck into thermal energy by friction and the brake pedal works hydraulically to retard the moving forklift truck. The other factors that support application of drum brake system are its lower costs and ability to serve as brake and parking brake as well. Principle of working of a drum brake is much similar to that of a disk brake since both involve pressing of brake shoes against a moving surface. The difference is that in drum brake system, that surface is the drum.
Many forklifts these days have both braking systems simultaneously incorporated, with disk brakes in the front wheels and drum brakes in the rear. Provision of drum brakes in the rear wheels gives additional and assured safety measure. Drum braking system installed in the rear wheels, prevent the vehicle from slipping away as it gets stopped by the application of disk brakes to the front wheels.
Drum brake system incorporates more number of parts. As the name implies, the drum brakes are designed to look like a drum, utilizing a wide cylinder with an open back. There are two large and curved brake pads inside of the drum, the brake shoes. As the forklift operator presses on the brake pedal, the curved brake shoes are forced outwards by the piston and wheel cylinders to strike with spinning walls inside of the drum. The process henceforth is a simple principle of physics, where the force of friction creates a retardation effect. The brake shoes, hence, create frictional force inside of the drum, which translates to slowing down the rotation of the wheel and ultimately putting it to halt.
Besides working as a progressive halting mechanism, the drum brake system in a forklift has the much needed emergency halting mechanism installed as well. This is carried out by the presence of the adjustor mechanism, an emergency brake supported with a number of springs. When the emergency brake mechanism is put into action, the brake shoes that spread out to halt the spinning drum come out even more forcefully. This is called a wedging action. The adjustor mechanism and the springs actuate to perform this operation when the brake shoes strike the walls of drum and create a wedging effect. The springs keep the shoes attached to the drum to help create the wedging effect, till the time the pressure on the brake pedal is released and the vehicle ceases to move. The other set of springs then pulls back the brake shoes in place and returns the adjustor to a normal position.
It is imperative in this system that the brake shoes should remain near to the drum, keeping a marginal distance as to prevent touching the walls. The close proximity is important and is a sign of better state of functioning of the Brake system. However, if brake shoes are far away from the drum, the piston will need more fluid for traveling near the drum. This will be experienced with the brake pedal pushed closer to the walls of floor. At this moment the adjustor will be engaged. The adjustor assesses the required distance maintenance and tends to keep it uniform. It acts to keep the ‘shoes to drum’ distance uniform, making the system work efficiently until the brake shoes are much worn out to fulfill the requirement.
The braking system, whether disk or drum brake system, is essentially dependent on the brake cables. The better these cables are, the more efficient is the transferring of braking signal becomes for the forklift truck. An efficient braking system depends largely on the right specifications, make and type of the brake cables. A lot of advancements have been made in this field, and better quality brake cables are being utilized in latest models of forklift trucks. A high quality brake cable will transfer maximum force to the brake shoes, which in turn will forcefully strike against the brake disks of the brake drums to effectively stop the forklift truck, before an unwanted collision.
Over time, forklift brake cables can start to malfunction due to normal wear and tear from its repeated usage. Even relatively new cables can cease to function when contaminants (water or debris) get into the housing. Since the brake cables connect the entire braking system, it is advisable that the operator checks for faults as soon as the brake pedal pressure is lower, as this can lead to further problems if ignored.
