At Hamilton, we are all in on engineering challenges. So when Service Caster tapped us to solve a laundry service dilemma, we didn’t hesitate to get our hands dirty.

The ask: Spec power-driven wheels for a drive application used in the laundry service’s pre-dryers. The pre-dryers, which spun towels at high speeds to drive out excess water and reduce time in the heated dryer stage, used wheels made from Nylon 6 material and employed keyways in the wheel hubs. Over time, the nylon didn’t hold up, the keyways elongated and the wheels failed. No bueno.

Enter Hamilton Nylast Wheels to the rescue. Why Nylast? As a popular alternative to steel, they’re made from solid cast high performance nylon and provide superior impact strength and resilience compared to conventional injection-molded nylon wheels (in other words, they’re much stronger than Nylon 6). Specially formulated with finely divided particles of molybdenum disulphide (MoS2), these wheel warriors enhance load bearing capability while maintaining the impact-defiant properties of nylon. Plus they’re moisture- and chemical-resistant, making them ideal for applications that demand sanitary conditions.

To make the wheels even tougher, we carved into them and inserted a special stainless steel core with the keyway to address the elongation. Nylast plus stainless steel equals pure driving power.

Fluff and fold, baby. Fluff and fold.

Tech specs:

  • Size: Special 8" diameter x 1-3/8" face width Nylast
  • Tread face: 6” radius crown
  • Insert: Flanged stainless steel (Type 304 Stainless Steel)
  • Bore: 2-3/8" diameter bore, with a 5/8" wide Class 1 Keyway

Why walk when you can ride? Life is better on wheels. They can even make the game of golf way cooler. Here’s proof: Meet the GolfBoard, a standing golf cart designed to forever change the rate of play. Made in the good ol’ US of A, it’s basically a giant electric skateboard that can ride up to 10 mph, letting you cut, slash and glide your way across the fairways in as little as half the time it takes players to hoof it through an average game of golf.

We especially like the 4” x 11” turf tires that provide maximum traction, and the 4-wheel drive is pretty sweet for scaling hills, too. It’s also got an ergonomically designed one-touch thumb throttle for zippy stop and go. Surfers and snowboarders will definitely appreciate the GolfBoard’s ability to “surf the earth” as the tagline states. Hang ten all you want. Your golf bag rides shotgun.

Now if it only had a cooler in the back and a cup holder on the side...

Watch how much fun these guys are having

The tiny pinholes that degrade airships can be tricky to locate and repair with the human eye and the human hand. Lots of man hours and manual labor, along with reaching nearly inaccessible locations. This time on the ground for maintenance defeats the purpose of airships when you consider what they were born to do: move massive amounts of stuff from one place to another efficiently and economically.


That’s why you send in the big guns from our friends at Lockheed Martin Skunk Works to create “Self-Propelled Instruments for Damage Evaluation and Repair,” better known as SPIDERs. These autonomous robots can scan and patch rogue holes on the vessel’s “envelope” in no time, literally shedding light on one of the greatest challenges to ever face the industry.

Watch as they weave their web of airtight precision.

From our pioneering history to our passion for American-made manufacturing, this quartet of curiosities puts the “H” in Hamilton: heavy-duty, headstrong innovation, hustle and history.

Fun fact #1: Heavy Duty

We do things big. Colossus is Hamilton’s largest and strongest caster every built, with a 100,000-pound capacity that soars 52 inches above the factory floor. Witness its birth.

Fun fact #2: Headstrong Innovation

Ingenuity is in our DNA. We’re one of the original inventors of kingpinless casters, with our patent for the legendary “Economic” going back to 1925. View the patent.

Fun fact #3: Hustle

Our unmatched PRONTO® service gets the product you need out the door and on its way within 24 hours. It’s not easy, but our team makes it happen every day.

Fun fact #4: History

Our president, Dave Lippert, is a two-time published author. Not only has he penned a book honoring the first 100 years of Hamilton history, but he’s also an authority on bringing manufacturing jobs back to the USA through reshoring. Get this book.

The world of casters is officially a safer place now that Hamilton’s new Ergo-X2 Caster Series has hit the market, bringing the final tricky issue with swivel casters to a halt: lockup. We’re conquering back injuries one pivot at a time by making it easier than ever for material handling operators to push and pull carts with confidence. Here’s why:

Swivel casters on carts normally have some offset—the horizontal distance between the centerline of the swivel and the wheel’s point of contact on the ground. When two or more swivel casters become misaligned as a cart comes to rest, a bind occurs when the cart operator tries to push it. In some cases, that bind can be significant—and unacceptable under strictly enforced ergonomic safety standards.

The Ergo-X2’s unique patented technology reduces these binding forces to get carts cruising again. Typical swivel assemblies in a caster only have one pivot point. The Ergo-X2 essentially provides a second pivot point—two precision machined ball races with the centerlines offset (traditional swivel bearing raceways share a centerline). Invisible from the exterior, this unique assembly gives the wheels more freedom to rock and roll like they were born to.

The release of the Ergo-X2 is particularly welcome news to safety managers hoping to prevent more push/pull workplace injuries, which cost employers more than $15 billion each year, according to Liberty Mutual Insurance Company. Since its common for safety managers to demand that push/pull forces not exceed more than 40 pounds, the Ergo-X2 paired with one of Hamilton’s ergonomic poly treads is the safer way forward.

When a leading Wisconsin-based paper mill needed an overhaul of its outdated, 50,000-pound-lugging cradle dollies, Hamilton created a custom design to breathe new life into their paper trails. To get all the juicy details, we caught up with Matt Olson, Hamilton Director of Business Development for Carts and Trailers, who worked onsite at the mill during design and construction to make sure we carried our weight.

How did the project come about?

Wisconsin Lift Truck Corp., one of our key distributors who has a long-standing relationship with the mill, reached out to us. They wanted to make sure they used a manufacturer who could provide them with the kind of quality they were seeking.

What was the issue with the current trailers?

The mill had designed and built the trailers themselves about 30 or 40 years ago. Over the years, they required a lot of maintenance and modifications and had basically lived out their useful lives. They needed us to bring the trailers into the 21st century to transport these heavy rolls of paper.

How did you work together?

We worked with both parties at Wisconsin Lift’s request. We came onsite to get a good feel for what the mill needed. We reviewed their history and expectations together. Then we toured the plant to walk in the path of the old carts and spend some quality time together.

Were there any design challenges?

The old carts had a lot of exposed surfaces that could cause some safety issues. Clearance issues with doorways and overhead beams were also a factor, so we had to design the trailers low enough to hold the paper rolls. They also had a unique hitch mechanism that connects the trailer to its towing vehicle, so we had to design for that, as well.

What’s the most unique thing about the trailers?

The size and capacity of the 15-foot-long trailers is remarkable. They have to carry these 50,000-pound rolls of paper, each of which is 110 inches in diameter. Each roll needs to be supported by just two cradles—one on each end of the trailer.

Go big or go home. That’s our philosophy. If mastodon-sized is wrong, we don’t want to be right. So you can imagine our excitement when we came across this video mash-up of five insane monster machines (Links to: that are revolutionizing how the world gets built. Here’s a quick rundown of their colossal credits:

  • Bucket Wheel Excavator. At more than 30 stories tall, this leviathan of German engineering is the tallest land vehicle in the world and can literally move mountains—up to 240K tons of rocks a day.
  • Segmental Bridge Launcher. At 580 tons and 300 feet wide, this behemoth launches across an existing bridge, hooks onto a pillar, moves forward to span the next pillar and rolls its next pre-cast segment into place. Watch as it skillfully snakes its way through China’s countryside.
  • Tunnel Boring Machine. Aptly nicknamed ‘Big Bertha’, this little lady grinds tunnels for the Washington State Department of Transportation and is the world’s biggest drill of her kind, weighing in at 6,700 tons and rising five stories tall.
  • Tree Harvester. This Ponsse Beaver beast effortlessly tears through the forest like a mythical giant, grabbing trees by their base, shaving their limbs and hacking them into toothpicks in 20 seconds flat.
  • Road Printer. It runs entirely on electricity and uniformly prints out 500 meters of pristine road a day. Workers insert bricks vertically into a pasta machine-like press that spits out one meticulously crafted path in its wake.

The bigger they come, the harder we fall in love.

There are moments when some of us here at Hamilton Caster dream about a future where we can control all our factory floor inventory by drone. The urge usually strikes when it’s about 80 degrees and sunny out…

Until that day comes, we’re happy to leave the drone capabilities to the good guys at NATO, who have acquired five new Global Hawk surveillance drones to be their eyes in the sky. The Hawks can travel by rain, sleet, hail, or snow at high-altitudes and will provide real-time surveillance to protect our ground forces and border and maritime security.

Watch as these sleek spotters travel at speeds of up to 310 knots.

We love it when the industries we serve go the extra mile to stay competitive, and that’s exactly what Ford is doing to battle the car manufacturer’s modern-day dilemma: In a world where camera phones are king, how do you road test tomorrow’s vehicles today without revealing all your secrets in plain sight?

The answer: A little camo goes a long way.

To ensure nobody peeps their latest and greatest designs before their time, Ford plasters its prototypes with lightweight camouflage stickers before sending them out for testing on public streets. The vinyl patterns use optical illusions to trick the eye and hide body lines, thereby helping to outsmart the leering lens of spy photographers everywhere. And since they’re lightweight, they allow for more accurate aerodynamic testing. Stickers are applied by hand and attached with Velcro closures for easy access.

All this disguise talk makes us want to decal our latest caster designs.
