Turn up the heat: new high-temp casters and wheels won’t sweat it

Thursday, December 15, 2016 4:28 PM  RssIcon

Call ‘em hot wheels for work. Call ‘em casters that won’t cook. Whatever you call ‘em, one thing’s for sure: these babies stay cool under pressure.

Hamilton is proud to introduce our new line of high-heat casters and wheels. Built tough to withstand the rigors of extreme temps, they’re ideal for rolling anywhere you want to beat the heat—especially in autoclaves, product finish systems, food manufacturing and pharmaceutical industries, where heat treating and coating is increasingly becoming the norm.

“We’re pretty excited about this series. Not everyone realizes that most conventional casters aren’t built to withstand very high heat,” explained Hamilton Vice President of Marketing Mark Lippert. “In the past, we’ve offered high-temperature wheels and casters to our customers on demand. As high-heat becomes more and more part of everyday manufacturing, we now have an extensive line to make it even easier to get what you need.”

Urethane wheels rock and roll any application

Monday, October 03, 2016 4:02 PM  RssIcon

If polyurethane wheels had their own playlist, “Start Me Up” by the Rolling Stones would definitely top the list. Why? Because a wheel’s startup force—or rollability—can vary significantly based on the type of poly tread used.

In fact, there are actually thousands of ways you can manipulate and cure a given urethane through creative chemistry to enhance or diminish its properties. That’s why you should never judge the quality or performance of a poly based on its color or hardness.

So which poly should you pick? That depends on your application. Today we’ll focus on three performance factors that are always top of mind: rollability, load capacity and durability.


Say you want to order pushcarts for manual operations in your workplace. You need to choose wheels that work best for your environment, load performance and worker safety. By selecting a wheel with high rollability, you’ll make your material handlers’ job easier and safer while helping to reduce workman’s comp claims.

First, pick the largest diameter wheel that’s possible and practical for your application. The larger the diameter, the easier the wheel is to push. Second, choose a poly wheel with a low startup force. Hamilton offers several polyurethanes designed specifically for strong rebound. A high-energy poly with great rebound like the Hamilton Ergo-Tech™ is an ergonomic favorite. It’s designed to minimize push/pull forces and reduce work-related injuries.

Load capacity

The heavier your load, the more both polyurethane formulation and thickness factor into effective wheel performance. Certain poly formulas are designed to carry more weight. For example, the Duralast® XC wheel carries up to 30% more capacity than our standard Duralast® and rolls easier on smooth floors. Keep in mind, however, that most loads don’t maintain an even weight across the length and width of a pushcart. An off-center load will prematurely wear the overburdened casters. Hamilton offers 3 standard polyurethane wheels specifically engineered for extreme loads.


Heat buildup is polyurethane’s number one enemy. Good thing durability is our specialty. We maintain strict specifications on our poly with respect to tensile strength, tear strength and rebound. Some polys, like our DuraGlide™, are engineered for very low thermal retention to stand up to heavy or continuous loads for longer service life. And Hamilton Super Ultralast® represent our highest performing urethane. It features the ultimate 1” extra thick Ultralast poly molded to a super heavy-duty forged steel center for off the chart performance that outlasts the competition.

You know what they say: Tough wheel. Long life. Happy budget.

Ready for a live performance?

In total, Hamilton offers 12 standard polyurethane-treaded wheels for almost any application. All the wheels provide great floor protection, quiet operations and long use with minimal wear, but to really help you choose the right revolution for your needs, use our handy cheat sheet below.

(And in case you were wondering, the poly wheel that rolls on our production floors at Hamilton is…drumroll…the Ergo-Glide™. We like it for its great ergonomics, durability and value for the money.)

These start-up forces noted above are based on the acceleration of 22 in/sec2 which is equivalent to the acceleration from zero to 2.5 mph to a normal walking pace. A slower acceleration (slow pace) will produce smaller starting forces.

Imagine it. Then 3D Print It.

Monday, May 02, 2016 1:52 PM  RssIcon

The advent of 3D Printing, at first a novelty, has become a vital tool for innovative high tech companies like Hamilton Caster. While GE and Ford have touted their rapid progress with 3D printing, many other companies are achieving incredible accomplishments behind closed doors.

“At Hamilton our investment in 3D printing has had a surprisingly larger impact on our company that we first thought,” says Jevon Lambright, a design engineer at Hamilton. “We’ve used it across several divisions including sales, marketing, R&D and operations.”

For example, a customer requested a unique mounting plate with mounting holes in odd places. As a proof of concept to make sure the part would work, we used our 3D printer to make a prototype.”

Check out some other ways that Hamilton has leveraged this technology.

A prototype for the new Ergo X2 Swivel technology

Prototypes of new foot operated swivel locks.

Not limited to engineering, our Lean 5S events created a demand for 3D printed tool holders on the factory floor.

Wheel of Fortune: The Ancestor of GPS

Wednesday, February 24, 2016 8:39 AM  RssIcon

Odd and sometimes useful facts that might help you win a non-cash friendly bar bet some day.

Long before satellite-powered Garmin and Google Maps sat on the dashboard, the Iter Avto navigation system rode alongside drivers of the day.

Created in the 1930's, it worked by scrolling a map as you drove along. The device was attached to a cable similar to a speedometer cable so the scroll speed of the paper maps coincided with the speed of the vehicle.

The major problem was that as soon as the driver turned a corner they would have to put a new map in. Well, it was a start!

Hamilton’s Big Screen Debut at Detroit Auto Show

Friday, January 29, 2016 8:52 AM  RssIcon

Ford’s “Go Further” motto not only reflects its supercharged attitude, but the automaker’s bold new trade show look.

Enormous, caster-driven video walls dazzled Detroit Auto Show guests at Ford’s main exhibit. Hamilton’s Maxi-Duty wheels guided the 30 by 60-foot screens, designed by award-winning design and manufacturing firm, Mannetron in collaboration with EWI Worldwide.

“Ford wanted a showstopper,” said Peter Jungen, engineering and design manager at Mannetron. “Typically, these screens run on tracks. But that wasn’t an option because Ford wanted something clean that wouldn’t detract from the experience.”

A combination of magnetic tape, sensors, Hamilton muscle and wicked-smart engineering made it possible.

“The screens moved on a pre-determined path set by a computer,” said Jungen. “The sensors, mounted on the wheels, picked up the magnetic tape and guided the screens back and forth with the help of an autonomous vehicle.”

In synch with Maxi-Duty

The Maxi-Duty wheels provided ample capacity to tote the 16,000-pound screens, which played video, images and visual effects to synch up with the cars on display.

For example, attendees could snap their pictures in the driver’s seat of a Mustang and have their mugs featured on the big screen. The video walls would then converge on each other like a curtain, revealing more of the photo mosaic by the inch.

Because guests could move freely about the exhibit, safety was a prime concern for Mannetron.

“We built in sensors that would detect if someone were nearby,” he said. “If they got too close, the whole thing would stop moving. We even built in logic to prevent someone from jumping in between the walls right before they closed together.”

Miss the exhibit? No worries. Ford plans to use the display for at least the seven years, which gives you plenty of time to scope out some pretty cool cars, and even cooler caster wheels.

Problem Solve Like NASA. Visit the Dark Room.

Wednesday, January 27, 2016 8:25 AM  RssIcon

NASA expected the Opportunity Rover to last 90 days. Nearly 12 years later, it’s still roaming the red planet. But the mission was nearly scrubbed, had it not been for the engineers visiting the Dark Room.

Aerospace engineer and author Adam Steltzner writes:

When you are solving a problem, you might find yourself stuck with no viable solution in sight. I call this place the Dark Room. It is a terrifying mental state, especially if you are on a timeline with an unmovable product debut date.

The problem he refers to? A fatal flaw with the Rover’s air bags. Because NASA borrowed a design from the 1997 Pathfinder craft, the team didn’t test them until a year from launch.

As Murphy’s law would have it, rocks shredded the air bags. And none of the team’s solutions could patch the issue. Enter the Dark Room.

There is a virtue in staying in the Dark Room until you completely surrender—not give up but completely surrender your ego, and stop trying to force the existing solution. That’s when a breakthrough occurs… you’re so completely drained and empty that you’re wide open to it, devoid of all prior notions, completely receptive. It’s the perfect blend of the conscious and subconscious minds working together.

After almost a year in the figurative darkness, he and his found a solution.

We emerged from the Dark Room triumphant that time. But you never know when you’ll be back in it again. It never gets less terrifying. Today when I’m confronted by the confounding uncertainty and stress of a seemingly intractable problem, I tell my teams, “Just keep working, and if death comes to visit us, let us be surprised.” Where there is will and ingenuity, there has always been a way.

Next time you reach an innovation road block? Head to the Dark Room. We know we will.

World’s Largest Solar Plant Is Visible from Space

Tuesday, January 26, 2016 8:24 AM  RssIcon

The world’s largest solar plant won’t fully power Morocco until 2020, but its half-million glistening mirrors are already visible from space.

The Noor 1 CSP plant is under construction deep in the Sahara Desert – a logical destination given it’s virtually always sunny and cloud-free.

When complete, the 6,178-acre plant will generate 580 megawatts and earn the title as largest concentrated solar power plant.

By comparison, that’s nearly double the energy output of the Solana Generating Station (280 megawatts), the top solar plant in the United States.

Originally, the Noor 1 CSP was set to supply power to European countries via cables through the Strait of Gibraltar. But when key investors pulled out, the Moroccan government stepped in.

The mega plant is projected to power a million homes, or about half the country.

Hamilton Wheels Turkeys to Flavortown

Friday, November 20, 2015 8:43 AM  RssIcon

They may look run-of-the-mill, but these mold-on rubber tired wheels have one very special job: to ensure nothing comes between you and a juicy bird this Thanksgiving.

Bob’s Turkey Farm relies on Hamilton to dish out more than 10,000 turkeys during its busiest time of the year.

After being slaughtered and cleaned, the birds are loaded into a 350-gallon chill tank and kept on ice for three days to develop texture and flavor. Each four-wheeled tank, which weighs approximately 1,000 pounds fully loaded, holds roughly 65 turkeys.

From ice bath to pot pie

Following the ice bath, the turkeys head to a processing facility where they’re deboned and transformed into everything from meatballs to pot-pie fillings and classic ready-to-roast (or fry) turkeys.

Not ones to let anything go to waste, the farm uses the bones to cook homemade gravy, which hungry pilgrims guzzle down 3,000 quarts of every holiday season.

Bob’s daughter, Sue, says Hamilton’s dependable wheels provide more than enough load capacity, roll easily, and resist certain “fluids” that are pressure-washed off at the end of every day.

We’re thankful that a great family-owned company like Bob’s Turkey Farm chose Hamilton, and we wish them a wonderful Thanksgiving. Though, they’ll work straight through the holiday to prepare for the Christmas blitz.

Would You Drive a Cardboard Car?

Saturday, November 14, 2015 4:21 PM  RssIcon

The humble cardboard box can ship casters from Hamilton to Boise, and one day it may help you make the trip, too.

Meet the Origami Car. A full-size, drivable Lexus IS built with your discarded Amazon boxes.

The luxury automaker partnered with LaserCut Works and Scales and Models to create the literal box car.

In total, 1,700 cardboard sheets glued together by hand make up the sedan. Fully functional doors, rolling wheels, a gear stick – everything but the aluminum and steel frame, electric motor and LED headlights is cardboard.

We love the stylish looks. As for its durability? We’re going to guess you won’t find this ride atop Consumer Reports’ safety ratings:
