Proudly displayed in our offices, Hamilton’s original 1925 kingpinless caster could just as easily roll on the factory floor today.
While kingpinless casters existed on the market back then, Hamilton’s founder, John Weigel, saw the need for a stronger, more durable version.
He patented “The Economic” 90 years ago, which featured an unconventional upper raceway for added vertical load handling. View the 1925 patent here.
Although it may have been the toughest kingpinless caster during the Roaring Twenties, that’s where the similarities end when compared to Hamilton’s current models.
A second raceway wasn’t The Economic’s only unique feature. One casting made up its upper portion (cup element) with the lower segment (wheel frame) comprised of another.
In comparison, our current models feature a much stronger forged-steel mounting plate and ring with heat-treated raceways for much longer wear.
We hope you enjoyed this Hamilton history lesson. Now, we’re onto the future – a new spin on kingpinless and our next generation. Watch your inbox, see it up close and in person March 23-26 @ PROMAT Booth 1934 & 1936, or snag a copy of your favorite industry magazine next month for our big reveal.
With Hamilton’s custom hydraulic running gear assembly in command, the U.S. military can safely load [REDACTED] onto cargo aircraft.
We designed and engineered three assemblies that connect to the government’s existing ground support equipment.With our rig in tow, the crew backs the tall machinery up the ramp without scraping the roof or belly of the plane.
Here’s how it works. When the load reaches the top of the ramp, our assembly’s hydraulic cylinders lift it 7.5 inches to keep the haul completely level with the plane’s fuselage. A pivot axle rotates the assembly roughly 15 degrees while it’s pushed up the ramp by a massive tugger.
Heavy duty, 25-inch pneumatic tires keep the load from getting stuck on the Tarmac. And an auto-steer construction stabilizes the 6,000-pound equipment while it moves over rugged terrain.
As for the [REDACTED]? That’s confidential.
Calling all fabricators: You supply the frame. We’ll build the running gear assembly. Email Jim Lippert, or call us at 888-699-7164 to learn more.
Hamilton’s 100% made-in-America casters helped make Ford’s F-150 the most American vehicle. The pickup topped a Cars.com list of “Most American” cars, which means it’s built with 75 percent or more USA parts.
Rounding out the top five included the Toyota Camry, Honda Odyssey, Toyota Sienna and Toyota Tundra. Despite being owned by Japanese companies, they’re mostly made with in United States factories with American parts.
For F-150 owners, the truck’s star-spangled flair isn’t the only reason to cheer. The 2015 model was recently named U.S. News & World Report’s top full-size pickup truck.
As for the casters? Hamilton’s 100% made-in-America casters help automakers, like Ford, crank out more trucks and cars than ever with less downtime caused by junkyard casters.
San Francisco’s new Movable Median Barrier System keeps the Golden Gate Bridge from turning into a six-lane, 1.7-mile-long parking lot.
The 30-ton, 60-foot-long “zipper” trucks crawl down the center median at 10 mph, shifting the one-foot-wide barrier from one lane to another.
It’s no small feat, either. At 1.7 miles long, the bridge is made up of 3,500 individual steel and concrete-filled barrier segments that weigh 1,500 pounds each.
Prior to the barrier’s installation last January, a row of plastic cones was the only thing separating oncoming traffic. Since 1971, lane crossovers have caused 16 deaths on the bridge.
Next time you zip through the Golden Gate safely and without delay, make sure to wave at the Moveable Median Barrier System.
See the truck in action below. It’s oddly satisfying.
You worked tirelessly. Pounded the phone. And fired off emails day and night. All to crush your first quarter sales goal. And now that you’ve succeeded, you may struggle moving onto the next.
Harvard Business Review author Ron Friedman writes, “When the constant sense of urgency we’ve adapted to comes to an abrupt halt, we experience withdrawal.” Symptoms of burnout may include procrastination, cynicism and lack of motivation. How do you avoid burnout? The HBR Blog suggests:

While wooden decks protect loads from scratches and dents, even the toughest oak or Trex® can’t withstand mold, mildew and Mother Nature’s wrath.
To build this custom trailer for an aerospace manufacturer, Hamilton spec’d a mineral-added plastic lumber made from recycled high-density polyethylene (HDPE), or milk jugs.
Because it contains no wood fiber, the ultra-durable composite deck resists rain and humidity, which warped the wooden decks on the company’s old trailers.
Here are the tech specs of Hamilton’s eco-friendly trailer:
Hamilton’s new addition to its caster lineup handles up to 20 tons and keeps a low profile.
The Enhanced Maxi-Duty (EMD2) Series features forged steel wheels for heavy manufacturers who need to boost load capacities without increasing overall height.
A hybrid of our Maxi-Duty and Ultra Maxi-Duty lines, EMD2 packs a small mounting plate and massive swivel construction. And dual-forged steel wheels machined with a slight crown for improved rollability and swiveling.
Best of all, a common mounting plate size (8 ½ by” 8 ½”) makes it easy to swap out existing casters with EMD2.
Our customers didn’t waste any time enhancing their heavy operations with EMD2. Some of the first ever built have already been deployed by the Department of Energy.

Astronaut ice cream might perplex us, but it’s hardly the weirdest thing NASA has hurled into space – besides humans, that is. Here are a few peculiar items that have literally gone farther than most of us ever will.
In 2007 the force was strong with astronauts on board the International Space Station. While some crewmembers packed flags and photos (they’re allowed up to two pounds of personal goods), one sci-fi junkie brought a lightsaber prop used by Luke Skywalker. Why? Star Wars director George Lucas asked him.
Dubbed the “Cola Wars in Space,” Coke and Pepsi hoped astronauts could settle the soda debate once and for all. In 1985 the Shuttle Challenger was equipped with specially designed soda dispensers for crewmembers to taste both zero G colas. Unfortunately, because of the lack of gravity and refrigeration, astronauts deemed the experiment/advertising stunt a failure.
This delicious, incredibly American combination could even be sent into space by you. Wait, what? For $60, you can buy a 600-gram air balloon to tote up to 1.8 pounds into near space, or an altitude of 105,000 feet. A two-day-old bacon hamburger and Natural Light beer are two of the most notable items people have sent up. In case you’re wondering, yes, Hamilton makes wheels that weigh less than two pounds. We’re on it…

Japan’s blindingly fast Maglev train could take you from Washington D.C. to New York – 226 miles – in less than an hour
Powered by electromagnets, the sci-fi-like train zips over tracks at speeds up to 311 mph. Unlike standard trains that run over tracks, the Maglev floats using magnetic levitation. Take that, gravity!
Recently, 100 passengers experienced its super-fast speeds for the first time, traveling 27 miles in less than 15 minutes.
For comparison purposes, America’s fastest train – Amtrak’s Acela Express – tops out at a “sluggish” 100 mph.
By the end of January, 35 percent of us will have failed our New Year’s resolutions. Why? Because we made our goals too complicated, i.e. bucket lists. Or, they’re just too vague, i.e. selling more casters.
Here are some realistic goals to strive for:
What are your goals in 2015? Ours include making the toughest casters on the planet even tougher. Tell us in the comments.
