It’s Halloween… Tales from a Small Town Boy Will Have You Shakin’ in Your Boots

Glen Roberts

With Halloween approaching fast, it has reminded me that over the years Cleveland Vibrator has sold several vibrators to entertainment enterprises for use on their Halloween projects. One of these projects, I was told, was for a Haunted Mansion Halloween Party for a pretty well known publication here in the U.S. (*Mansion may be a pretty big clue here). They used two 1125 VMS Air Piston Vibrators mounted below the floor to surprise folks as they walk on them. We even built an “Earthquake Machine” for the Natural History Museum here in Cleveland, Ohio to give visitors the experience of what an earthquake may feel like. They even covered the drive motors so you could actually sit on them. This holiday also brought back an experience I had at a burial vault company visit just a few years past. But, before I tell this story would like to explain what led up to my reaction to this visit.

I think that our beliefs and fears about Halloween go back to what we have learned or were told as kids. This for sure applies to my background as a youngin’. I was raised in Southern Ohio on a small farm that had no phone service until I was twelve or thirteen. Read More…


110v/60hz Vibrators, 3 Options: When to Choose Electromagnetic Vibes

Mike Stratis

The Cleveland Vibrator Company first opened in 1923. During the past 92 years, the flagship product for our company has been the pneumatic piston vibrator. However, as the industry has changed, our product offerings have been required to adapt to the customers’ requests. We have three options available for the users who require a 110v/60hz vibrator, which include:

Electromagnetic Vibrators

Why Recycle Glass? The Answer Is Clear

Katy Sabo

Remember the days of “Tube TVs” and “Low Radiation” computer screens?

I remember walking into Cleveland Vibrator and seeing, what I would describe as, the land of misfit computer screens that had been stored away through the many years that Cleveland Vibrator has been in business. One day they disappeared and the land of misfits was replaced by trade show accessories. Working here has opened my eyes to the many industries that don’t get the attention they well deserve, especially recycling. Recently, I was invited to visit a customer whose specialty was Glass Recycling of old TV screens and computer monitors. Ding, ding, ding, the lightbulb went off… this is where those “misfits” disappeared to. This got me thinking, what exactly can recycled glass be used for?

The glass used for these old monitors and displays is referred to as CRT, Cathode Ray Tube Glass, and it is estimated that the typical CRT device is made up of between 15 to 90 pounds of glass (depending on device) that protects the users from the radiation produced by the electron gun and beam gun inside that device. Since the emerging high demand of LCD, LED and Plasma Screens of the 2000s, it is an estimated 57 million computers and televisions are sold annually in the U.S. according to U.S. Environmental Protection Agency. Households are now discarding old models of outdated technology at a much higher rate than we have ever seen before. Read More…


Strike & High G’s, A Vibratory Table’s Compaction Conundrum

David Strong

My mom just had her 80th birthday the other day. To celebrate the milestone, one of my sisters and her husband are taking my mom on an Alaskan cruise, I’m sure it will be a great adventure. A few years back I had the opportunity to visit Alaska as part of a Cleveland Vibrator Company project, I was there to provide start up assistance and review the installation of a piece our equipment. From start to finish it was a very interesting application of mechanical vibration to assist in the compaction of a dry material. Throw in a trip to Alaska and it became quite memorable.

Cleveland Vibrator Company was contacted by a large engineering firm that was involved in a remediation project at a military installation in Alaska. The company was removing contaminated soil from the site.  The soil was to be placed in steel containers and shipped off site. Their challenge to us was to increase the density of the soil, put more material in the box than could be accomplished with just “dumping” soil into the container. Read More…


Stroke, Frequency and Force: The Keys to Vibratory Compaction

David Strong

One of the more common applications for industrial vibration is to settle or compact a wide variety of products.  This ranges from foundry sand around a core to powdered metal, beer bottle caps, individual sugar packets, ceramic mixes to concrete blends used in ATM wall enclosures.  This compaction process can be accomplished on any one of a number of vibratory equipment products including vibratory joggers (VJ), vibratory packers (VP) either pneumatic or electric powered, flat deck tables (FA), grid tables (GT) where the vibrating table is integrated with a roller section or the vibratory belt table (BT).  Regardless of the equipment used we start by understanding the material and working with a few basic parameters to accomplish the task.

The most critical parameters in any compaction problem are Read More…


Improving Production Speed of Cast Concrete

Jack Steinbuch

In designing and manufacturing custom vibratory equipment, I see customer inquiries for a myriad of potential applications to solve production challenges or improve production rates.  Recently, a producer of decorative stones presented us with a challenge.  The stones are produced from wet cast concrete mix molds.  These molds need to be vibrated to de-aerate (remove air bubbles) and consolidate the concrete in the molds.  This was being done manually on a vibrating table, typically one mold at a time.  They wanted to automate their production to reduce their labor time.  They had invested in production equipment that would quickly fill the molds, but had yet to come up with a method to take advantage of that automation by vibrating each mold at the same rate.

We concluded that our Read More…
