In our never-ending quest to move loads as safely as possible, Hamilton now offers custom e-Power Cart Solutions. With a payload capacity range from 2,000 to 40,000 lbs., our motorized carts can help eliminate all manual operations to get the job done safer and more efficiently.
Research from the Liberty Mutual Research Institute for Safety shows that push/pull forces in excess of as little as 35 pounds can contribute to musculoskeletal workplace injuries. Powered carts can help you move heavy payloads while achieving your ergonomic and performance goals. Here’s how you can benefit:
Keep work zones forklift free
Especially handy for when you’ve exhausted all manual transport options for heavy loads, powered carts offer easy maneuverability in tight spaces. Many carts can pivot from the center point, making rotating cargo in tight spaces a snap. Motorized carts are also ideal for moving stock that final distance from trailer trains to the assembly line. There’s no need to transfer materials from a warehouse trailer to a smaller conveyance for manual handling. No need to use a forklift for lateral transport. The powered cart does it all.
A flexible workhorse
Take the unique dual-purpose trailer featured in the photo (above?). It can tow heavy loads long distances as a conventional trailer as well as maneuver cargo into final position for production. Since anyone can position the loaded trailer without additional help, powered carts can be a safer, more versatile and more economical choice in the long run when every minute counts on production floors.
Operating the powered trailer is easy. The drive wheels automatically retract when you lower the towing tongue to enable safe and easy transport. Raise the tongue for manual maneuvering and the wheels come down, ready for powered movement.
The cart comes with running gear to expedite manual operation, such as when you need to quickly align empty trailers for towing. It features 12” Hamilton Ergo-Glide Polyurethane wheels to minimize rolling friction and maintenance-free front Spinfinity casters with 8” x 3” Swivel-EAZ® wheels. With a spacious 36” x 72” deck, the cart can tow up to two tons of precious cargo. The CP00070 wishbone and companion CP00120 pintle hitch provide safe and practical towing.
The electric drive unit is variable speed, retractable for towing, and has intuitive hand controls with a back-up safety brake, horn, and battery level indicator. On/off switches are keyed for controlled access, while rechargeable batteries offer hours of manual operation.

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:
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?
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.

The older you get, the more excited you are about giving gifts than receiving them. That’s how we feel every time we load a custom trailer onto a flatbed truck.
All the hard work and sweating the small stuff led up to this moment. Now the trailer our engineers and factory technicians worked on for weeks – sometimes months – is about to journey off. And hopefully exceed our customers’ expectations.
It’s a special feeling. And yeah, we’re getting gushy. But we hope you feel the energy through these photos. We take a lot of pride in what we do, and want to share it with you.
To remedy a Texas hospital’s flat-lining trailers, Hamilton prescribed a heavy dose of aluminum and crafty engineering.
Two custom all-aluminum trailers tote food-service carts around the institution’s campus. They replace crumbling rigs you’d expect to find at a dilapidated theme park.
Each trailer features five parking spots to lock the food carts in place during travel, two drop-down loading ramps, and a roof to protect against the elements.
Why aluminum? According to truck designer Jake Eichold, it’s all about mobility and sparing added expenses.
“These trailers travel 15 mph,” said Eichold. “Aluminum is significantly lighter than steel, so they didn’t need to purchase more powerful towing equipment.”
Meeting the customer’s demand for a 13-inch deck height presented a unique challenge.
“Anything over 13 inches, and the ramps would be too steep for workers to push the food carts up onto the trailer,” he said. “The issue here was that if we mounted the wheels in line with the deck, they would increase the trailer’s height.”
Instead, Jake and his team built two upper decks to house the 16-inch pneumatic wheels.
“This kept the deck low,” he said. “And we avoided the engineering nightmare of mounting the wheels outside the frame, and trying to link them with the steering system.”
Minus the orange flair, it looks like your typical double fifth-wheel steer trailer. But inside, it’s anything but.
An electric-powered slew drive makes the upper deck rotatable, which helps a tier-one auto supplier spin its way to huge safety and quality-control gains.
“Before our trailer, they used a fork truck to move 30,000-pound dies,” said John Yater, a Hamilton design engineer. “Trouble is, because of how the dies had to be unloaded, it forced workers to transport them sideways instead of lengthwise through extremely narrow aisles.”
This left about two inches of clearance on both sides of the truck while it journeyed from storage to the manufacturing bay.
“Two inches doesn’t leave a lot of room for error,” said Yater. “One scrape could damage the load, or cause it to fall off the truck. And the sideways orientation impedes the driver’s view, so it’s a worker safety issue, too.”
With Hamilton’s trailer, workers now load the dies in the direction of the trailer for transport, which opens up more than a foot of space on both sides of the trailer.
When the trailer reaches the production facility via a tugger – which also serves as its power supply – the die rotates 90 degrees before being unloaded.
A single rotation takes roughly 2.5 minutes, with a full 360-degree turn clocking in at 10 minutes. This may seem like forever in manufacturing, but a slow and steady turn helps keep workers safe, and protects the equipment.
For added durability, our engineers spec’d and installed ball transfer units to surround the slew drive to prevent damage if the load isn’t perfectly centered.
“The ball transfer units safeguard against shock loading and stop one side of the trailer from being overloaded, which could cause the slew drive to fail,” he said. “Accidents and mishaps can occur, and we always account for that.”
While the auto supplier only recently put our trailer to work, we’re told the crew already feels much less claustrophobic.
