When cargo goes high, Hamilton trailers go low

How low can you go?

This was the question posed to Hamilton for a recent custom order we delivered to a leading aerospace and defense company. They wanted a nimble trailer to transport a very large electrical switchboard being manufactured for the U.S. Navy.

Hamilton engineers immediately got down on the ground to “rise to the challenge,” so to speak. The customer needed a highly maneuverable trailer for two reasons: 1) Their largest forklift truck was not able to safely lift the load and move it around on the factory floor 2) They wanted a trailer that could spin around from its center—not only to safely corner extremely tight aisles but also so the switchboard could be worked on while on the trailer itself

Height and agility were key here. The trailer couldn’t be higher than eight inches off the floor so workers could safely service the switchboard without a ladder (the switchboard doesn’t sit directly on the trailer but rather on a steel base and large shipping pallet that adds approximately 16 inches to the switchboard height). In the photos, you can see that our casters are almost camouflaged like covert Ninjas working their magic under the hood.

To stay low and nimble but also handle the weight, the trailer uses swivel casters on all four sides, with directional locking steering casters placed at the center. This makes it easy for electric tuggers to push or pull the trailer any which way. Heavy-duty floor locks at each trailer corner ensure that everything stays put while the switchboard is being worked on. The customer’s ultimate goal is for future switchboards to be built from scratch directly on the trailers.

The end experience is stealthy, streamlined and safe, with minimum footprint. The trailer is just slightly larger than the footprint of the base that the switchboard sits on.

Everything you need. Nothing you don’t. And safety, always. That’s Hamilton trailers.

This trailer drops it like it’s hot

Here's the deal: What you need to understand is that Hamilton loves making custom trailers that can do anything our customers want them to. Nothing pleases us more than focusing all our powers and resources to make industrial towing power happen. In the case of this drop deck trailer, we went low, so productivity could go high.

Check it out: a beast of a cart designed to transport outrageously heavy and cumbersome plastic injection molding dies indoors for maintenance and upgrades. The trailer had to be able to attach to an e-power pusher— those practical & flexible powered trailer products designed to eliminate the strain of manually pushing and pulling heavy carts and wheeled equipment. So we did a collaboration with one of our material handling partners to produce a one-two punch of load-hauling greatness.

The drop deck in the center works double duty: it keeps the center of gravity as low as possible and reduces the overall height of the load as it’s transported through the plant. The trailer’s rigid tongue was custom engineered so it’s perfectly positioned to attach to the e-power pusher. Underneath, Hamilton’s 22-inch diameter TerraTech Press-On Polyurethane Wheels are designed with extra large precision ball bearings that reduce the force required to initiate movement - which is an important benefit when pairing with a power pusher.

And now for the drop-deck gorgeous specs:

An uncommon trailer for a common application

If you’ve ever watched stamping dies—those one-of-a-kind precision tools that cut and shape sheet metal parts—do their thing, you know they’re pretty cool. You also know they’re pretty heavy. It’s a good thing Hamilton carts are masters at transporting monstrous stamping dies for our customers everywhere. In fact, it’s one of the most common applications for which we build trailers.

Here’s a pic of a recent beauty we designed for a major American car manufacturing facility. Engineered to withstand a whopping 100,000-pound payload, the cart features a wooden deck for extra scratch protection. Four-wheel steering ensures the 180-inch-long cart is cornering tight aisles and intersections like a champ.

It all adds up to one wheely productive ride.

Die Transport Trailer

  • Capacity: 100,000 lbs.
  • Deck Size: 96" wide x 180" long
  • Deck Material: Wood
  • Steering Type: 4-wheel steer
  • Running Gear: Triple-mounted 22 x 10 press-on polyurethane wheels with tapered bearings
  • Color: Safety Yellow
  • Superstructure: Superstructure: None
  • Couplers: Front: Loop-type towing tongue; Rear: None

This crankshaft trailer has great wheel karma

They say one good thing leads to another. In the Hamilton universe, the more it’s about wheels, the greater the good, in our opinion. That’s why this custom trailer we designed for an engine components repair company has so many good wheel vibrations. Created to transport crankshafts weighing up to 10,000 pounds, it features two fabricated steel cradle wheel assemblies (one fixed, one adjustable) to rotate different-sized crankshafts. The wheels can also be mounted in three different locations, depending on the crankshaft’s main journal size. Lifting shackles attached to the cradles provide the option to secure the crankshaft in place. We also designed a custom socket to install the wheels, as well as special wheel-attaching hardware to be flush with the wheel’s width profile. And that’s just for the wheels on top.


Special sockets were designed then CNC-Machined inhouse to secure the cradle wheels.

The trailer’s dual wheel casters (mounted up inside the frame to help minimize the center of gravity) with ball bearings help reduce the force needed to move the cart, while holes punched into the cart side rails provide easy swivel lock access for a tight stop. There are also mounting holes on all four sides to accommodate a powered pusher for extra power.

It all adds up to one wheely productive ride.

Crankshaft Transport Trailer

  • Capacity: 10,000 lbs.
  • Deck Material: Smooth steel
  • Steering Type: Steering caster style
  • Running Gear: (4) S-EHD-12DB-4SL
  • Color: Safety Yellow
  • Superstructure: Includes 2 fabricated steel cradle assemblies (1 fixed and 1 moveable) to carry various length crankshafts. The moveable cradle features 82” horizontal travel with infinite latching positions within that travel. The cradles are approximately 12” tall to allow crankshafts with counterweights to be manually rotated and clear the deck. Crankshafts are supported using wheel type rollers that contact the main journals of the crankshaft.

The yin and yang of Hamilton trailers

Duality. It’s what keeps life humming in harmony. A prime example: this custom trailer we designed for a prominent wastewater general contractor. Sure, it’s easy on the eyes, with its sleek lines and bonny colors. How can something so beautiful be so brawny, you ask?

The custom trailer was ordered by a prominent wastewater general contractor to transport sludge screens in a harsh operating environment (fun fact: sludge screens are used to remove unwanted debris, such as hair and plastics, from waterways to reduce blockages). Good thing we equipped the trailer with stainless steel hardware, mold-on poly tread wheels with aluminum centers, and a tough epoxy paint finish. Because the screens can be cumbersome to handle, we added a bumper around the trailer perimeter to provide extra protection when loading and unloading, as well as to guard against incidental contact. A tongue-activated parking brake ensures the trailer stays put when stored.

Cue the Zen-flowing summary:
