vibrators for safety applications

Let’s Clear the Air on Vibratory Drives for Hazardous Locations

Jack Steinbuch

Over the years I’ve received a number of requests for vibrators or vibratory equipment that need to operate in a hazardous location.  Most requests include the classifications they are either given or think they need, but often aren’t familiar enough with them to know what their application may really require.  I believe for vibrating motors especially, that most confusion stems from recognizing the difference between dust tight and explosion-proof construction.

Our challenge for these applications is to clarify the classification being requested and offer possible alternatives to meet them.  First, to my understanding, pneumatic powered drives are acceptable for any hazardous location. You only need to be concerned if you use an electric activated valve to start/stop it, to make sure it meets the classification of the hazardous area.

hazardous-environments-class-description-cleveland-vibratorThere is a considerable amount of data for classifications, but I referred to an article which I felt handled the topic in a very informative manner.  They started by defining the Class or type of material present as specified by NEC (National Electrical Code) and CEC (Canadian Electrical Code). Class I location is specified as a location containing flammable gases or vapors. Class II locations contain dust that is Read More…


Grain Bin Safety Week: How Rescue Tubes and Proper Training Will Save Lives

Glen Roberts

Did you know that the pressure of engulfing grain is so powerful, that it takes more than 1,500 pounds of force to free a body submerged under less than two feet of grain?

I must admit that although Cleveland Vibrator has supplied Industrial Vibrators and Equipment to the grain and feed industry for many decades, I was not aware until I took the Asmark Safety Course how many folks are trapped, injured or killed inside grain silos and feed mills. A lot of the grain safety training applies to just about all industries and mirrors the manufacturing industry, which I have  worked in and been associated for over 45 years. Two major things I picked up from this training were:

  1. Tag out and lock out is huge anytime you need to work on a piece of equipment, or when you are in an area that normally has running equipment.
  2. Checking your tools to make sure they are in good working order which includes inspection of the guards and making sure you have no frayed electrical cords. Generally, this is just good work ethics  in any work environment. Read More…

Top 6 Ways to Keep Your Employees Safe in the Grain Handling Industry

Katy Sabo

Valuing your worker’s safety and well-being are ideas that most can agree on being crucial for company success within dangerous industries such as Grain Handling. Part of my job is updating our Twitter Feed and keeping an eye out for industry news via shared stories and retweets by some of the most credible sources in the material handling industries. Recently, I have been seeing numerous stories about grain entrapment accidents and can’t help but wonder, why does this keep occurring when preventive measures are available?

Grain Entrapment and Engulfment: Rail Cars

Craig Macklin

Well, this sad news was released recently: “Worker Engulfed in Rail Car…” which made me revisit my prior post to dig into data some more.  Once again, I went to the data set provided by NPR Buried in Grain. This time I looked only for “rail car” in the incidents and found two in the data set.  While the two incidents in the data set both correspond to workers trying to clear clogs while unloading the rail car hoppers, this new incident does not.  Its cause was related to the worker slipping and falling while loading the car.  Either way, these incidents are terrible, tragic and preventable with proper safety precautions and training.  Rail car vibrators are one tool to help prevent bin or hopper entry during unloading.  I encourage anyone following these continued incidents to look into resources available from organizations such as the Grain Handling Safety Coalition.
