4/5/2018 8:32 AM  RssIcon

When it comes to trailer applications, there’s no one-size-fits-all. Many variables affect performance and cost—load size, wheel arrangement, deck size and steering type, to name a few.

So how do you choose the right trailer for the job? Study all your options and select the system that makes the best sense for the specific application. This handy Hamilton white paper breaks down everything you need to know, including:

  • An overview of different steering systems, complete with a matrix that compares performance, handling, capacity and cost
  • How load size, inclines, aisle width and environmental factors (e.g. rough floors, extreme temperatures, heavy debris)
  • Common everyday scenarios around maneuverability and safety concerns

The cart that rocks the cradle rules the world

1/20/2018 2:47 PM  RssIcon

Just because we love creating indestructible carts and casters doesn’t mean we don’t have a softer side. Take a recent custom trailer we completed for one of the world’s top producers of plastics.

It’s designed to haul 800-pound vertical eductors that are part of a chemical plant’s infrastructure. Macho stuff, right? Well, the cart also features four cradle assemblies with adjustable heights to not only accommodate different eductor sizes but also raise and rotate them in place as they’re being repaired. Each cradle includes protective rubber pads to ensure gentle handling, while clamps provide added control. For even more agile positioning, the modular cart uses four swivel casters with position locks on each caster for high maneuverability.

Call us crazy, but we like to coddle our cargo just right.

Here are the specs:

  • Description: Eductor Transport & Maintenance Cart
  • Capacity: 500 pounds
  • Deck Size: 32" wide X 84" long
  • Deck Material: Smooth steel
  • Steering Type: Swivel caster style
  • Running Gear: (4)Champion swivel casters with 8" diameter X 3" wide Ergo Glide wheels fitted with precision ball bearings & 4 position swivel locks
  • Superstructure: 4 individual cradles approximately 30" above the floor. Cradles will have a durable, protective surface for eductor to rest on. Eductor will be in 2 halves - each half will be supported by 2 individual cradles. Cradles will have a clamp mechanism to secure the eductor section to the cart. Bolt-on cradle assemblies to be adjustable horizontally along the deck surface to facilitate various versions of the eductor - cradle locations needed upon time of order. 4 adjustable risers to raise cradles from 30" to 42" above the floor
  • Other: Push handle on both ends
  • Finish: Safety Yellow Epoxy

“I’m all brawn and beauty” said our custom truck of the month.

9/26/2017 2:40 PM  RssIcon

Hamilton carts and trailers help customers move giant, heavy things with greater ease and efficiency. It may not be sexy. But it literally helps the world go ‘round.

Take this 30-ton capacity custom truck we recently designed for one of the world’s largest energy and industrial giants. The customer needed a beast of a trailer, tough enough to haul giant transformers for repair at their apparatus service center. Some of the transformers weigh as much as 420,000 lbs. The customer had previously been using rail carts to tote the transformers along railroad tracks. Limiting!

We designed a four-wheel reversible trailer with auto steer and a four-point lift, capable of transporting giant cargo around the service center any which way. Here she is, with her slick safety yellow finish. Isn’t she a beauty, with her towing tongues at both ends? Couldn’t you just look at her all day, while she glides across your factory floor, making heavy lifting look easy and carefree? Don’t you want to take her home to mom?

Here’s her dating profile:

  • Trailer type: Four-wheel reversible auto steer
  • Capacity: 30 tons
  • Deck size: 72” x 168”
  • Deck height: Approximately 27”
  • Tongue height: Approximately 11 ½”
  • Running gear: Dual mounted W-POY-1590-2 press-on poly wheels
  • Towing tongue at both ends, locked vertical when not in use
  • 4-point lifting provision
  • Internal fork pockets

Because you need to know about trailer steering now.

7/30/2017 2:43 PM  RssIcon

You know that trailers come in all shapes and sizes. But you should also know that there are all types of steering options, too. The way your steering system operates can make or break any application. Good thing we’ve summarized everything you need to know below.

Type 1: Caster Steer trailers

  • Design: Two swivel casters at one end, two fixed-load wheels or rigid casters at the other
  • Good choice for its simplicity, and for an economical way to both power tow and push by hand

Type 2: Fifth Wheel Steer trailers

  • Design: Single pivot point for the front axle/wheel assembly and fixed rear wheels (Think a kid’s little red wagon)
  • Great for power towing, singularly or in trains
  • Can be towed at higher speeds than Caster Steer trailers
  • More economical than Four-wheel steer trailers
  • Highly versatile
  • Work great pulling solo

Type 3: Four Wheel Steer trailers

  • Design: No fixed axles; both axles pivot for steering and are connected to each other by a tie rod
  • Best bet for pulling longer trains of trailers through tight aisles and intersections, or anywhere aisle width space is at a premium
  • Pricier than single Fifth Wheel Steer Trailers

Auto Steer trailers (general)

  • Offer maximum stability
  • Running gear stays fixed under load corners as you turn (as opposed to a Fifth-wheel steer where the entire axle assembly turns)

Two Wheel Auto Steer trailers

  • Design: mimics an automobile
  • Less expensive and easier to back up than Four-Wheel Auto
  • Smart choice for maximum stability when towing solo
  • Will track similar to a fifth wheel steer

Four Wheel Auto Steer trailers

  • Design: front and rear steering like automobile, connected by a tie rod to coordinate tighter, more accurate turns
  • Pricier than two-wheel auto steer due to more sophisticated turning engineering
  • Best for towing long trains or when you need reversible towing*
  • Will track similar to a non-auto four-wheel steer

Other good things to know

  • Never “push” or put trains with more than one trailer in reverse. This can lead to structural damage.
  • *Reversible towing means towing from either end (not backing up!)

Hamilton trailers: Lean, mean and ready to roll in more ways than one

6/27/2017 2:39 PM  RssIcon

We love it when a trailer works overtime to speed up productivity. Case in point: A custom cart we recently created to haul water distribution equipment castings (think fire hydrants) from manufacturing to storage and shipping. The deck’s free-spinning conveyer rollers make it much easier to load and unload the castings from either side. Easy rolling wheels with special ergonomic polyurethane treads help this cart function safely even when moved manually under load.

No wonder this trailer was created as part of the customer’s lean improvement processes. Hamilton puts the skinny in lean manufacturing.

Here are the specs:

  • Load Capacity: 3,000 lbs.
  • Steering Type: Caster-steer trailer
  • Deck Material: Conveyor rollers across the width of the deck, 2" lip along each side frame and a hand actuated stop 1" high and 6" long centered at each end. Stops can manually be raised and lowered.
  • Running Gear: Two each S/R-ZFFM-83EGB swivel and rigid casters with 8" x 3" "Ergo-Glide XT" wheels with precision ball bearings
  • Superstructure: Removable pipe handle located in sockets welded outside the frame at the swivel caster end with horizontal pipe extensions on the jaw end to act as stops for the lip handles.
  • Dimensions: 51" wide x 51" long x 18" height to top of the rollers
  • Couplers: CP00030/40 heavy duty safety automatic couplers
  • Color: Platinum Gray

Nuclear waste? There’s a trailer for that.

5/30/2017 2:38 PM  RssIcon

Every day, companies across the world trust Hamilton carts to tow their precious cargo. That’s a responsibility we don’t take lightly—especially when the haul involves nuclear waste, as is the case with a recent custom job of ours for a massive environmental cleanup commissioned by the Department of Energy (DOE).

These waste carts are being used to help disassemble a massive government nuclear power plant from the 1950s. The carts are carrying heavy pieces of equipment once used in the process of enriching uranium, so it’s critical that disassembly is done properly and safely. Deactivating and decommissioning a facility involves removing hazardous and radioactive materials, verifying that criticality isn’t possible, and de-energizing and disconnecting nonessential systems. In other words, tricky stuff.

The trailer deck also doubles as a work platform while equipment is being loaded atop the trailer. To make sure any towing tongues don’t get in the way while they’re working on equipment, our tongue stows neatly underneath the frame to avoid the trip hazard.

Just another day doing our part to make sure people stay safe and work smart.

Tech specs:

  • Deck Size: 120” W x 240” L
  • Steering: 2-Wheel Auto-Steer
  • Stowaway tongue for added safety
  • Capacity: 35,000 lbs.
  • Trailer Weight: 7,200 lbs.
  • 5 lifting rings on each side of the trailer deck for a total of ten (10).
  • Press on Poly Wheels utilizing tapered roller bearings
  • Color: Platinum Gray

When there’s nowhere to turn, it’s Hamilton trailers to the rescue.

4/26/2017 3:16 PM  RssIcon

In the world of heavy-duty manufacturing, space can sometimes be at a premium. And that’s okay, when you’ve got Hamilton custom carts on the case.

We recently helped a world leader in wire and coating haul heavy coils in tight spaces. The customer had previously been racking up costly bills using expensive semi-trailer trucks to move product across the street from one building to the other. They needed a more user-friendly, cost-effective way to get the job done 24/7. And because there was no room to turn the trailers, Hamilton designed a reversible train system that easily changes direction. Tongue couplers at both ends make it easy to attach and disconnect tuggers moving to and from the two buildings.

Toot, toot. All aboard that gravy train to better productivity.

Here are the tech specs:

  • Description: All Steel Reversible Four Wheel Steer Trailer
  • Capacity: 25,000 lbs.
  • Deck Size: 102" W x 168" L x 19-1/4” H
  • Deck Material: Diamond Tread Plate Steel
  • Steering Type: Four Wheel Steer
  • Running Gear: 8 dual mounted, 12" diameter x 4" wide Superlast® polyurethane wheels with tapered roller bearings
  • Couplers: Tongue at each end of train of 2 and permanently coupled, designed for reversible towing; tongue when not in use will stay in the upright position
  • Other:
    • Slots in the deck for McMaster-type hook straps
    • Reflectors around the edges and tail lights with plug in front to plug in lift truck
    • 12 McMaster-type hook down straps to fit in slots provided on the trailer

Hamilton trailers don’t have to move a muscle—until you want them to

3/27/2017 3:20 PM  RssIcon

Nothing says productivity plus like a trailer built to save money and human muscle. Case in point: This custom trailer we recently designed to haul large circulating water pump motors from warehouse to power plant.


The customer had previously been using heavy timbers to mount and house the motors. Not only were the timbers cumbersome for crews to remove manually; the motors also required expensive crane rentals for transport. The customer was also keenly aware of how towing is safer than lifting with a crane, due to less inherent risk.

We designed a special square trailer that doubles as both storage platform and hauling hero. The motors can safely rest on Hamilton trailers until moving day—all that’s needed is a forklift hookup and they’re ready to roll. With an 80,000-pound capacity, the trailers also give the 54,000-pound motors plenty of breathing room. We also provided a hole in the truck’s center for the motor’s coupling to pass through. Added chain hooks keep cargo snug and secure on the decks.


Because, you know, safety first.

  • Model No. XT2889
  • Open frame double fifth wheel steer with lockouts
  • Capacity: 80,000 lbs
  • Deck Size: 120" wide x 120" long
  • Deck Material: open-frame
  • Steering Type: double fifth wheel steer with lockouts
  • Running Gear: eight dual mounted 22" diameter x 10" wide press-on polyurethane wheels with tapered roller bearings
  • Couplers: loop-type towing tongue at each end, each 26" high above the floor
  • Other- tie down rings, four total, one at each corner
  • Stenciling & Marking: "80,000 lbs capacity" stenciled on each side frame
  • Color: yellow epoxy finish
