You know we can’t resist anything that rolls. #wheelsrule
When a Fortune 1000 company needed custom trailers for their new four million square foot facility, Hamilton engineers were ready to roll with a solution.
After sizing many different decks to suit the customer’s needs, we designed a roller trailer to transfer palletized goods on and off the deck safely and securely along the production line, making it easier than ever for workers to load/offload product from assembly to either warehousing or shipping. Removable side rails allow manual access via forklift, if necessary.
“Moving away from forklifts has been a growing safety trend in manufacturing plants,” said Dave Lippert, President.” One way to move materials smartly and safely without forklifts is with a properly designed trailer like this one.”
It’s nice to have options, though. So this trailer includes removable side rails for manual access via forklift, if necessary.
With two rows of rollers arranged lengthwise on the trailer frame, the deck features removable rear-end stops and fixed front end stops (one set for each roller lane) to secure product in place during travel. For added stability, ZB style foot activated brakes on both front wheels ensure precious cargo doesn’t slide anywhere it isn’t intended.

Just ask our friends in the oil and gas industry. Hamilton recently partnered with an international productivity solutions provider to custom-engineer two trailers specifically designed to load and transport large, cumbersome components for assembly.
“Handling these parts can be challenging. They’re heavy and irregularly-shaped, not to mention fairly expensive,” said John Yater, Hamilton lead design engineer on the project. Yater and his team worked with the customer to create safe, cost-effective and modular trailers that could be secured and handled in multiple ways. Productivity, check. Safety, check, check.
The XT2814 trailer—designed to support wellheads—is a quick study in ergonomics. It’s got an extra thick deck armed with forged adjustable clamps that are perfect for locking down flanges of all different sizes and thicknesses. No flanges? No problem. Lashing rings can be used to secure the load. Its rear tube bumper is designed for easy power pushing, while the tubing sub-frame is lined with internal guides to mate easily with a lift table. Everything rolls on our indestructible Superlast® wheels: their steel centers and thick polyurethane treads ensure a quiet, gentle ride for giant loads, while the caster swivel locks keep maneuverability stable during transport.
Just like the XT2814, the XT2813—engineered for valve trees—is designed for easy loading and transport with the same casters, tube bumper and fork pockets. It’s also highly adjustable for both assembling and disassembling parts. A wide range of parts can be moved in four different directions: left and right, up and down. The deck is slightly tilted so that oil can properly drain out one end.
Here are all the specs:
Bring us your Cretan bulls, your nine-headed Hydras. Our new colossal-sized trailers are ready to take on your toughest towing battles, pronto.
Hamilton is proud to announce Hercules, a new line of pre-engineered super duty industrial trailers. With a load capacity range of 20,000 to 40,000 pounds per trailer, they’re ready to power blaze their way through any plant. Plus they’re engineered for quick turnaround, and available to ship with an unmatched lead time of four to five weeks (most high capacity industrial trailers have a minimum lead time of seven to eight weeks).
Just how much tout-suite muscle are we toting? The Hercules line is available in a total of 10 standard deck sizes that range from 4-feet-wide x 8-feet-long to a whopping 5-feet-wide by 24-feet-long. Ideal for hauling tooling, dies, molds, structural steel bars, rolls, cylinders and plate steel, the series is grouped in 20K, 30K, 35K and 40K load capacities designed for severe loading and power towing conditions.
Our design engineers selected heavy duty press-on polyurethane wheels that range from 14-inch to 22-inch diameters on the 20K and 40K load trailers, respectively. And with its forged steel loop designed for extreme loads and solid fifth-wheel steering construction, these trailers are destined for years of service-free wear and tear.
Want to meet Hercules in the flesh? Check out our product page for more information. And be sure to bring your best muscle tee. If trailers had biceps, ours would flex in their sleep.
In the Oil and Gas Industry, moving heavy, odd shaped components is common. Doing so in a safe and productive way can be challenging. Hamilton teamed up with a leading international provider of sustainable productivity solutions to provide the end user with a robust cart designed specifically for economically moving wellheads through an assembly process. The extra thick deck is slotted for t-nuts and forged adjustable clamps that adjust and secure a multitude of flanged components with varying flange diameters and thicknesses.
The cart has a tubing “bumper” to facilitate propulsion by a power pusher. Underneath, that same tubing sub-frame is lined with guides to align the cart over a lift table for assembly work. The lift table raises the component to a height that suits the worker. Internal rectangular fork guides provide access for fork trucks lifting the cart. Lashing rings can be used to secure the load to the cart, or the cart to something else.
Heavy duty 8” diameter X 3” wide Superlast wheels, with tapered bearings, are mounted into forged steel kingpinless rigs. These wheels feature indestructible forged steel centers and thick polyurethane treads to provide quite operation, floor protection, and ample load capacity. Caster swivel locks can be used to provide directional stability during transit, yet maximize cart maneuverability when needed.
XT2814 Technical Specifications
Of all the special finishes requested for Hamilton trailers, galvanizing may be the most unique. The concept is to make something metallic corrosion resistant by immersing it in a molten zinc bath. Anticipating the galvanizing process, engineering applied some very specific features. For example, the design required extra holes for air release and draining. No part of the trailer could have potential for an air pocket. Under the extreme zinc bath temperatures, which can reach 800 degrees Farenheit, trapped gasses can cause an explosion.
Building a galvanized trailer required some non-standard production procedures. Normally a trailer is fully welded and then assembled. For galvanizing, the trailer had to be hot-dip galvanized in separate pieces. This meant we delayed assembly to send five major components to galvanizing. Assembly occurred after returning from being galvanized.
This trailer is designed to move a large heavy duty filter to and from a maintenance shop. The travel path is 300 meters over asphalt road. Large 16” diameter solid pneumatic wheels with tapered roller bearings are ideal for varying paved terrain under relatively heavy loads. The trailer capacity is 10,000 lbs. Key features include two removable cradles, four robust handles, perimeter lashing rings for securing the load, and fifth wheel steering with a directional tongue lock. The customer wanted to be able to lock the steering wheels into a straight position to allow for pulling with a winch. The cradles are removable so the trailer has a secondary use as a typical flat deck fifth wheel steer trailer. The cradles are bolted directly to the frame to minimize fastening hardware. For safety and convenience, the towing tongue can be locked in the vertical position. The 44” trailer width assures lateral stability with the load in place, considering a 25” deck height and a large cylindrical filter secured on top of that.

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.
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.
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.
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.
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.
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.
A locomotive repair campus needed industrial trailers to assist with the distribution of parts. The large Midwestern campus featured many buildings, connected by roadways in various stages of disrepair and some gravel pathways. Repair parts arrived at one building, and then were transported to different buildings where they were needed.
Being a locomotive repair campus, there were multiple rail crossings to negotiate, along with the gravel pathways and other roadway conditions. Working closely with Hamilton engineers, the customer communicated the environmental challenges, the intended usage, and the variety of load sizes and weights. The proposed design incorporated a unique running gear system, robust wheels, a wood deck, and a substantial steel frame.
Hamilton provided special torsion type axles that afforded 3” of vertical travel. When coupled with heavy duty reinforced 19” diameter pneumatic wheels, encountering rail crossings was not a problem, even with full 5,000 lbs. loads.
A spacious 50” wide by 150” long deck provided more than ample space for the many loads. The deck surface was wood to minimize load slippage during travel.
The customer planned to tow five trailers in a train, so Hamilton engineered plenty of strength into the trailer including central longitudinal frame members. Rear axle location optimized stability and turning. Simple but stout forged steel loops on the tongues and pintle hitches on the rear made trailer towing easy and safe.
Interestingly, the department using the five trailers had to guard against others on campus confiscating them for their use. Not intending to promote campus rivalry, Hamilton calmly suggested new trailers for the others as well.

Sometimes it takes an engineer to get the marketing right. Our challenge to the engineering department was to demonstrate the cool way that Hamilton’s four-wheel-steer industrial trailers work.
“Game on!” said the engineering department.
Using our 3D printers, the engineers printed the RC Tugger and Four-wheel-steer Trailer. Taking it a step further, as engineers always do, they 3D printed scale models of the industrial trailers and built a mock-up of a distribution floor to boot.
Of Hamilton’s four steering systems, the most popular type is the four-wheel steer design that can navigate turning in tight aisles. Check out our video that demonstrates this capability here. Makes you want to dig your remote control cars out of winter storage, doesn’t it?
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.

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.
