Realizing that maintenance and repair costs of plant floors include lost production time, inefficiencies, worker comfort and safety, our customer was concerned about protecting the expensive concrete floors in their brand new facility.

Committed to a failure-free environment, an aircraft manufacturer challenged Hamilton to a create heavy duty caster with a low contact pressure.

The company required 128 heavy duty casters each rated at 15,000 lbs. and designed to apply a maximum contact pressure of 750 psi per caster to the concrete floors. No small task.

Working with our customer and a key supplier, a four-person team at Hamilton buckled down. Using computer modelling, the team zeroed in on a polyurethane wheel design that achieved the desired results.

After hours of computer simulation, the prototype exceeded the customer requirements resulting in a wheel with two-inch thick tread of Hamilton's new DuraGlide polyurethane material that delivered 698 psi per caster, well below the customer’s psi requirement.

Once the wheel spec was finalized, Hamilton machined and fabricated the dual wheeled caster with a toe guard and a dual heavy duty brake.

The client appreciated Hamilton’s efforts. “You were the only supplier to dig in your heels and come up with a solution. Hamilton was committed to meeting our challenge. The magic worked and the casters are on the stands. Thank you again for all of the technical support! These are cool!!!

A new material handling system. An army of existing push carts. The challenge? Tow existing push carts throughout the plant using a custom designed mother cart that’s both adaptable and economical.

The solution? The Hamilton Mother Cart XT2759.

It’s open on one side so the customer’s existing carts can be pushed in easily. Spring loaded mold-on rubber locking wheels retract inside the cart’s frame when the daughter carts reach their resting spot against the dock bumpers.

A quick touch advances the control lever to the locked position and the over center toggle linkage is engaged to securely lock the cart for transport.

Locked and loaded, wheels equipped with precision tapered bearings handle the thrust loads during towing. Hamilton’s precise steering geometry ensures that the cart will follow seamlessly, minimizing wheel scrub, vibration and wear.

The end result is world-class equipment tailored for our customer’s exact application. Case closed.

You’ve circled the block three times looking for a parking place. There’s no garage so you’re forced to parallel park. Ah-ha! One space between a Lexus and BMW. Maybe, just maybe, you can squeeze in. You tug at the wheel and inch your way backwards taking care not to hit one of the luxury cars...

Goodyear looks ahead to a better way. Spherical shaped Eagle-360 tires can move backwards, forwards or sideways. The concept tires introduced at the Geneva International Motor Show earlier this month, can reshape the future for autonomous cars.

Besides outstanding maneuverability, embedded sensors in the Eagle 360 communicate road and weather conditions to the vehicle control system and even to other nearby cars. The 3D printed tread mimics the pattern of the human brain and behaves like a sponge. The tires stiffen when dry and get softer in wet conditions to deliver excellent driving performance and resistance to hydroplaning.

So buckle up and drive – well, thataway. See a demo.

On a typical day, Marcus Daily served 300 customers from his sidewalk hot dog cart in Washington, Missouri. But lines were so long that he had to do something. He set out to build a bigger hot dog cart and got carried away.

So carried away that Guinness World Records recognized the new cart as the largest hot dog cart at 9 feet, 3 inches tall by 23 feet, 2 inches long and 12 feet, 2.75 inches wide. The wheels and the sides are embossed with diamond-patterned quilted stainless steel.

The colossal push cart – and yes, it is movable – is a scaled-up stainless steel model that is three-and-a-half times the size of the original, as verified by a State of Missouri land surveyor.

The Hotdog Man’s cart is a full-time family-run business and he claims that his hot dogs are the “world’s best”. Serving only Nathan’s all beef jumbo hot dogs, his menu includes 33 different hot dog combinations, as well as a few other items, like nachos, gyros, tacos, bratwurst and Italian beef sandwiches. Prices range from $3 to $12.

It’s a hard choice between his most expensive concoction, the D-Day Dog, which features two hot dogs, six cheeses, bacon, Italian beef and a second bun on top and the best selling Wonder Wienie topped with cream cheese, red onions and jalapeños.

Pass the mustard!

The most expensive and most advanced warship ever built will hit the seas in June. With a price tag of $13 billion, the USS Gerald R. Ford can house more than 4500 sailors and weighs 90,000 tons.

In addition to its generous size, the new aircraft carrier introduces several technical innovations that improve operating efficiency and reduce operating costs and crew requirements.

The new launch system replaces the conventional steam catapult and can launch a jet every 45 seconds, 25% faster than the old technology. The new system can also launch drones and other electric vehicles.

AESA, a new search and tracking radar system enables the ship to transmit powerful signals and yet remain stealthy.

Defensively it packs a powerful punch. The Evolved SeaSparrow Missile (ESSM) counters high-speed, highly maneuverable anti-ship missiles, and the weapon system is the Rolling Airframe Missile (RAM). In addition there are Gatling and heavy machine gun mounts as well as 75-plus aircraft, ready to be launched at any given time.

The average American loses 40 minutes of shuteye each year on the night after DST begins, according to sleep researchers at the University of Michigan. While you may think you make up for that lost time when we “fall back” later in the year, researchers found that survey participants didn’t sleep significantly more when they gained an hour in October…which brings the typical American to that cumulative loss of 40 minutes of sleep per year. The researchers’ report, used data from the Bureau of Labor Statistics analyzed the sleeping patterns of 14,310 working Americans.

Excess weight? Oddly shaped products? Noise? Short turning radius? Believe us, it takes a lot more than that to break a Hamilton Engineer.

Their latest challenge was to custom design an ergonomic braking mechanism with a toe guard for a major aeronautics manufacturer.

Done! The special application contact brakes feature an integrated toe guard. It sits only 1-1/2” off the floor and prevents workers from trapping their feet beneath the cart. No more smashed toes. Or ruined pedicures!

The braking mechanism’s ergonomic design ratchets back stress on the operator’s body, too. There isn’t the traditional push-down, and pull-up motion required to engage and disengage the brake. The new mechanism engages and disengages with a much more ergonomically friendly push-down motion. In addition, red and green brake arms flag the on and off states of the brakes.

This customer required a smaller envelope than the standard contact brake so the new profile has a shorter turning radius.

Bottom line, if you have a tricky application, there’s a Hamilton engineer who’s dying to sink his teeth into it. So challenge us!

Tech Specs

  • Capacity - 1,000 pounds
  • Swivel offset - 1-1/2"
  • Overall height - 12-1/8"
  • Mounting plate - 4-1/2" x 6-1/2" with mounting holes 2-7/16" x 4-15/16" slotted to 3-3/8" x 5-1/4" for 1/2" bolt size
  • Wheel - W-1041-SPRT-1
  • Rig finish - red enamel
  • Equipped with 4-position swivel lock

There’s a lot to love about Hydroid Autonomous Underwater Vehicles (AUVs).

The REMUS 600 cruises along in ocean depths of 600 to 1500 meters. Like a Hamilton cart, REMUS specializes in missions that require extended endurance and increased payload capacity. Hydroid’s diverse defense missions include complete area searches, organic and expeditionary mine countermeasures, and to conduct surveillance and reconnaissance.

The REMUS 600 is graceful and stable at the ocean floor, but it needed an expert land-lubber assist when back on solid ground.

On land, Hamilton made a splash with a 1,200 pound custom cart.

Hydroid teamed up with Hamilton to design a custom cart to load AUV’s onto a truck or trailer for transport to a marina. Special tie down rings on the cart secure it to the truck during transport. No wiggle room here.

Once at the destination, the cart encounters more obstacles. Rough, uneven surfaces often with steep angles, bumps and hairpin turns on boat ramps and wooden piers. With the expensive vehicle on board, the cart has to perform like a superstar.

Hamilton planned for that. The aluminum cart can handle salt water and salt air. The radius is padded with a soft cradle to hold the vehicle snugly in place. Corrosion resistant zinc plated casters with heavy duty foot activated contact brakes ensure the cart and cargo remain stationary.

When in motion, it’s a cushy ride. Instead of hard wheels that won’t absorb the shocks from the docks, Hamilton engineers selected 12” x 3” semi-pneumatic Super-Flex wheels. These wheels provide super cushioning and won’t go flat avoiding costly downtime.

In addition to transport, the cart is also used for storage of the AUVs. And with the accessible design, the cart can function as a stand while workers make adjustments to the vehicle.

Tech Specs of the REMUS 600 Autonomous Underwater Vehicle Transport Cart

  • Capacity: 1,200 pounds
  • Perimeter Frame Size: 30" wide X 66" long
  • Frame Material: Aluminum
  • Steering Type: Swivel caster style
  • Running Gear: 2 swivel casters and 2 fixed wheels all with 12" diameter semi-pneumatic Super-Flex wheels with precision ball bearing
  • Superstructure: 4 "U" shaped cradles - the 2 end cradles are fixed, the 2 intermediate cradles to be moved laterally to compensate for various options on the AUV. 3 movable tie downs on each side (6 total). "U" shaped handles on both sides used to steady and guide the cart.
  • Couplers: Towing eye attached to each end frame

You may slather butter on bread and lobster, but people in Harrisburg, Pennsylvania have an artsy use for butter. A thousand pounds of it. People from far and wide flock to see butter sculptures– and those are just the cardiologists.

Every year at the Pennsylvania Farm Show, the largest indoor agricultural show in America, artists spend weeks sculpting butter into art.

It’s been a tradition since 1991. From a huge Benjamin Franklin and the 2002 commemoration of the heroes of the September 11 attack butter is a big draw at the farm show.

This year’s sculpture depicts the show’s theme “Blue Ribbon Experience” and features a young girl with a cow, a 4H member with baby chicks, and a couple showing off apples and pies behind a quilt and spinning wheelIt took 2 people 14 days to sculpt this year’s entry.

After the show, the butter is converted to methane and powers a farm for up to 3 days.
