Cranes are important machines used in various jobs, such as construction, manufacturing and shipping. They are used to lift and carry heavy loads, making them an important part of the supply chain. To ensure safe and efficient crane operation, it is important to have a proper braking system.
The main part of the crane braking system is the crane brake liner. In this article, we will examine what crane brake linings are, why they are used, the types of brake linings available, and the various benefits.
WHAT IS A CRANE BRAKE LINER
Brake Liner is a friction material used to provide stopping power to the crane’s braking system. The brake line is attached to the brake shoe and is pressed against the rotating drum or disc to slow or stop the crane. It is an important part of the crane braking system, as it ensures the safety and reliability of the machine. Without brake lining, the brake system will not be able to function properly, which can lead to safety problems and the machine’s downtime.
BRAKE LINER DESIGN
Brake lining materials are attached to metal or ceramic supports, such as brake shoe, using heat-resistant gaskets, heat-resistant rivets, or high-tech adhesives. The brake lining material has a high rate of friction as kinetic energy which is required in the braking process is converted into thermal energy. Therefore, in addition to being solid or textured (complex), the materials used in the production must be strong and resistant to high temperature and pressure.
Variety of non-metallic and semi-metallic materials can be used by manufacturers to create
create brake linings. Although they often use standardized materials, manufacturers can
combine materials of different compositions and thicknesses.
Due to the health risks of asbestos exposure, such as the development of lung cancer, other lung diseases, or mesothelioma, the friction materials are no longer made of asbestos fibers. Some linings are made with hard brake material, but this makes sense if the accompanying clutch plate or drum is also strong and of good quality. If not, wear and tear can happen very quickly. Sometimes it’s better to use a soft and light brake pad.
Regardless of the specification of the lining that produces it, friction is important for all braking systems since it is the system that allows the machine to slow down properly. Therefore, you need to pay attention to a few different things to make the brake system connected to the brake line, whether it is a lift, tractor, car, or machine or vehicle
THINGS TO BE KEPT IN MIND WHILE CHOOSING A BRAKE LINING
To be able to maintain this coefficient of friction in a wide range of thermal values, the brake lining must have values with a high coefficient of friction. The amount of friction decreases as the heat value of the brake increases. Brake linings must be resistant to high heat and abrasion. The brake lining should not get damaged and it should wear slowly and should have a long service life.
- The brake lining must be silent while rubbing (because these sounds are causing discomfort).
- The brake machine should not lose it braking qualities due to extreme heat.
- Foreign material resistance is required for brake lining.
- When it is rubbed, the brake line should not make noise.
- The brake lining must have coefficient values with a high friction
- The brake cover must be protected against foreign substances, including water, dirt and dust.
