The Evolution of Industrial Vibrators: From Pneumatics to Electric Powered Vibrators in the 20th Century

The Cleveland Vibrator Company started manufacturing air operated vibrators in 1923 and for several years air vibrators is all we pretty much offered. This worked well in our primary foundry customer base through the first half of the 20th century. As we expanded our customer base, we found more and more customers wanting to use electrical power to operate the industrial vibrators. It became obvious that we needed to give our sales staff an alternate source besides air to offer our valued customers.

88-mc-2-electromagnetic-continuous-duty-vibrator-aid-large-chain-of-bakery-plantsWe started with fairly basic electromagnetic vibrators with the MC-1, MC-2 etc. and started to introduce these units into the market place. The MC series is considered the “grandfather” to our current CM-5, CM-10 and CM-30 and more recent Super 30 vibrators. You can see a success story of this product in the field in the case study on the right hand side of this paragraph. In the early 60’s, we contracted with a company from Sweden called Dynapac to market and sell their rotary electric vibrators mostly here in North America. They were supplied in 1800 RPM and 3600 RPM (revolutions per minute) which opened the door to customers having hoppers, bins, chutes, bunkers as well as other applications which include vibratory tables, feeder and screeners.

Ah! The Good “Old” Days at the Cleveland Vibrator Company

When you have been around a company as long as I have, you look back at times and reflect on how the products you offer and a even how your workforce interacted with each other has changed compared to the same workplace of the 21st century. After thinking back, I wanted to mention a few of the lighter moments from the 1970’s and some of the pranks we used to pull on each other. Let’s start with a few humorous moments on testing new products and repairs of larger Foundry Flask Vibrators.

In the early 1970’s, Cleveland Vibrator picked up another product line called “Air Blasters” or “Air Cannons”. They were basically welded tanks with an inside rubber bladder which was inflated with air from 80 to 100 PSI and you would release the pressurized air using a pressure relief valve thru a 4 to 6” diameter discharge pipe. This would send a blast of air into a large bin or silo to break up large collections of grain that had adhered itself to the inside walls. We ordered and received our first unit and of course had to test it before shipping to our valued customer. Read More…

It’s High Noon Partner With Our Pistol Grip Vibrator

Over the course of 90 plus years, the Cleveland Vibrators developed several types of portable air piston vibrators. Some have long since ridden off into the sunset and some are still used today but with far less sales than the 50’s, 60’s, 70’s and 80’s. The Pistol Grip vibrator was one of those hand held units from late 60’s to early 70’s that was successfully developed mainly because a customer said, “I need this and if you build it we will buy it.” Cleveland Vibrator did build it and they did buy it but it turned out to be one of those limited edition models with a higher price tag so folks used other more standard units for basically the same application. This was a precast concrete form application and the customers would walk around and place the vibrator against the form at  selected spots to mainly settle the concrete and remove air bubbles which would generate a better finished product. The main feature of this unit was the ability to carry it in your hand and not have it vibrate until you squeezed the trigger. Plus the handle had a rubber grip helping to isolate the vibration force from the operator. Read More…

Cleveland Vibrator has a lot of things to be thankful for…

In light of this week’s Thanksgiving Holiday, I thought I would take a minute to share a few thoughts with our loyal movers and shakers.

Personally, this past year has given me many blessings to be thankful for (i.e. graduating from Akron, getting engaged and moving into the next chapter of life) but I truly believe that being given the opportunity to work for Cleveland Vibrator was the beginning of the “good vibe train” life has thrown my way. Over the span of one short year, I have gained so much from coming to work day in and day out here at Cleveland Vibrator. One can only appreciate the great perks of working for a smaller company simply by experiencing it for themselves. So here’s a few things we are thankful for… Read More…

Industrial Vibration Now & Then: Portable Pneumatics

Katy Sabo
test

One of the perks about working for The Cleveland Vibrator Company when you’re a history geek like me, is digging through the archives and learning the rich history of your product development over the past century. Recently, I was able to get my hands on case histories dating back to the 1960s and came across one that highlighted our first-ever “Portable Air Piston Vibrator.” Nearly 50 years ago, Cleveland Vibrator assisted a precast concrete manufacturer when they wished to improve the consolidation and finish of their product using vibration. We specially designed a 1-1/4″ Piston Vibrator and attached it to a pistol-grip handle. The handle had been equipped with a special thumb grip trigger that activated the vibration and this piece of vibratory equipment weighed only 10 lbs. This light-weight and portable option gave the manufacturer the power to apply vibration to problem-child areas within their production, leaving the application locations completely limitless. How much did this unit cost? For the vibrator, 5′ hose and lubricator, this manufacturer paid $80. Read More…

Tough Mining Application Calls on Cleveland Vibrator Co. for a Tougher Solution

Glen Roberts
test

One of our strong suits has always been the ability to manufacture special vibrators for tough applications. The mining industry can be a major challenge for any air piston vibrator do to heat, extremely dusty environment and just the harshness of the application to include operating the vibrators in a 24/7 operation. The Erie Mining Company in Northern, Minnesota had such a process. They were established in 1957 for the mining of taconite ore. The process involved taking taconite, which is a hard low-grade iron ore mixed in with nonferrous rock and grinding it to separate the low grade iron ore. One of the intermediate processes is screening for further separation. This is where Cleveland Vibrator came into play. Read More…
