Band brakes are simple braking systems used as a backup or primary brake assembly for machinery such as hoists, power saws, and bicycles. They have fewer moving parts, are easy to maintain, but may not work efficiently in moist or high-temperature environments. They can be installed as a backup to a primary system and are commonly used in manufacturing and construction settings.
Band brakes are simplistic braking systems that are sometimes included as secondary brakes that can be used should the primary braking system fail. While designs vary slightly, a basic band brake involves the use of one type of band that is placed around a cylinder. When tightened, the table causes the cylinder to slow down and eventually stop its rotation, which in turn causes the machinery involved to stop as well. This type of band brake assembly is commonly used on some machinery as a backup to other braking systems and can also be the primary brake assembly for various types of hoists, power saws, transmissions and bicycles.
One of the main advantages of a band brake is the simplicity of the design. With fewer moving parts than other types of brake systems, a band brake assembly is easy to maintain and can function properly for a number of years without failure. As long as the drum or cylinder used in the project is kept clean and free of rust, there is little chance of jerking or snagging that would interfere with the braking action. As long as all components are properly inspected and maintained, the brake will continue to efficiently control rotational speed and, if necessary, even stop that rotation.
There are potential drawbacks to using a band brake which make it important to consider the application before actually choosing to use this particular type of braking equipment. The brake is less likely to work efficiently in situations where the drum or cylinder is exposed to moisture, such as rain or snow. In situations like this, the band or belt is likely to slip, delaying the braking action or preventing it from happening at all. High temperatures can also interfere with brake operation, making it difficult to stop an activity completely safely. For this reason, a band brake is often used with machinery such as winches or hoists rather than equipment that operates at high speeds.
Even with the potential liabilities of the band brake, this type of braking system can be installed as a backup to a primary system. Typically, the use of the secondary braking method can be activated manually in the event that the primary system is rendered inoperative for some reason. While slower than other braking solutions, band brake use in various manufacturing and construction settings is common and is likely to continue for many years to come.
