Certain types of conveyors require fail-safe brakes for stopping. These conveyors, often used in the mining and aggregate industries, include downhill conveyors (e.g., discharge and transfer conveyors), as well as overland conveyors with downhill sections. Not having fail-safe brakes on these types of conveyors can result in catastrophic damage if power is lost. For example, overspeed can result in damage to drive system components, clogging of chutes at transfer points, or general safety issues stemming from performing an e-stop. Some unique considerations related to designing a conveyor brake system include:
We recently summarized the most common industrial vibrator failure modes that we see. In our 35+ years of working with heavy duty industrial vibrators, improper mounting is consistently the single leading root cause of industrial vibrator failure. Because improper mounting has a tendency to cause a wide range of issues with vibratory equipment, our customers are often surprised to learn that an error in the vibrator installation process is the true culprit. To help you avoid this pain, let’s dive into more detail on how to properly mount your rotary electric industrial vibrator:
A holding or e-stop brake is used to keep a drive system from moving once the variable frequency drive has reached a near stop (i.e., near zero RPM shaft speed). In a holding or e-stop braking application, the brake generally isn’t used to stop the system except for emergency situations. The brake is always fail-safe, meaning that it is spring applied and will set itself in the event of a power failure.
Below is a summary of how we determine the best fail-safe holding or e-stop brake for our customers’ industrial applications:
Industrial vibrators are unique pieces of equipment. While often associated with electric motors, industrial vibrators have vastly different mechanical and electrical characteristics and can wreak havoc on your operation if misapplied and misunderstood. So that you know what to look for, below are the most common causes of failure that we see:
