How Much Does A Lowboy Trailer Weigh

Semi-Trailers

“Ever found yourself staring down a heavy haul job, scratching your head and wondering, ‘How much does a lowboy trailer weigh, really?’ I’ve been there too, and let me tell you, it’s not just idle curiosity. As an owner-operator who’s hauled more than my fair share of excavators and bulldozers, knowing the actual weight of my lowboy trailer itself is absolutely crucial. It’s the foundation for calculating everything else – payload capacity, axle weights, tire pressure, you name it. Underestimating this number isn’t just inconvenient; it’s a fast track to fines or, worse, a dangerous situation on the road.”

“So, what’s the answer? Well, pinning down one exact number for lowboy trailer weight is like asking how long a piece of string is – it depends! From my experience buying and running these trailers, the tare weight varies wildly. A basic single-drop 35-footer built mostly from steel might tip the scales around 15,000 lbs, but step up to a heavy-duty triple-axle extendable with aluminum decking and ramps, and you could easily be looking at 25,000 lbs or even significantly more before you add a single pound of cargo. The construction materials (steel vs. aluminum), deck length, number of axles, detachable neck design, and features like hydraulic ramps all play a massive role.”

“Why does this variance matter so much to me practically? Because that empty trailer weight isn’t just a number on a spec sheet; it’s weight eating directly into my precious legal Gross Vehicle Weight Rating (GVWR). If my lowboy weighs 20,000 lbs empty, that means I’ve only got the remaining capacity under my permits and truck’s capability to load my actual freight. Miscalculating this – either by not knowing my specific trailer’s true tare weight or underestimating it – is a surefire way to end up overloaded before I even realize it. Trust me, I’ve seen it happen, and the consequences at the scales or on a steep grade aren’t worth the gamble.”

Average Weight of a Standard Lowboy

From my experience, a standard two-axle lowboy trailer weighs between 15,000 and 18,000 pounds. We often call these 35-ton lowboys. I’ve found they are built to haul heavy equipment while keeping the trailer’s own weight down.

How Much Do Different Lowboys Weigh?

  1. Standard two-axle lowboy: 15,000–18,000 pounds. I recommend this lightweight option for most equipment.
  2. Heavy-duty or oversized lowboy: These can weigh up to 40,000 pounds. They are reinforced and best for very large or heavy loads.
  3. Triple-axle, 55-ton hydraulic gooseneck: This model is about 22,645 pounds. It has a 26-foot deck and a total length of 53 feet.

Common Specifications and Dimensions

  1. Deck length: 24–29.6 feet is typical.
  2. Maximum trailer length: Up to 53 feet.
  3. Standard trailer width: 8.5 feet.
  4. Deck height from ground: You’ll find it’s usually 18–24 inches.
  1. Two-axle lowboy: I advise keeping the total weight (trailer + cargo) at or below 40,000 pounds to stay legal.
  2. With extra axles: You can legally haul a combined weight up to 80,000 pounds.

What Changes a Lowboy’s Weight?

  1. I want to point out these weights are for empty trailers.
  2. If you choose a heavy-duty design with reinforced parts or extra axles, the trailer will weigh more.
  3. Based on my experience, the final weight is set by the maker, the setup you choose, and any special features.

2-Axle Lowboy Weight

2 Axle Lowboy Semi Trailer

From my experience, a 2-axle lowboy trailer is a great choice for moving large, heavy equipment. It gives you plenty of clearance and stability. I think these trailers find a good middle ground. They have a low empty weight but can handle a high legal load capacity.

Parameter Specification / Data

  2. Max legal load (no permits): 40,000 pounds
  3. Max gross weight (with permits/extra axles): up to 80,000 pounds
  4. Deck dimensions: 24–30′ long, 8.5′ wide, 18–24″ height

Based on these numbers, I believe a 2-axle lowboy trailer is a practical and legal choice for many heavy-hauling jobs. You can also get permits or make upgrades. This allows you to increase the payload when you need to.

3-Axle Lowboy Weight

3 Axle 15 Ton Lowboy Semi Trailer

I use a 3-axle lowboy trailer to move very heavy and oversized loads. When you are choosing one, I suggest you check two main things: the empty (tare) weight and the maximum payload it can haul to stay within the law.

3-Axle Lowboy Trailer Weights and Capacities

Empty Weight: From my experience, most 3-axle lowboy trailers weigh between 18,900 and 23,000 pounds when empty. A standard 55-ton, 53-foot model weighs about 22,645 pounds. A heavy-duty 65-ton, 53-foot, non-ground bearing model has a tare weight of about 23,000 pounds, with a small margin of ±3%. I’ve seen some lighter 40-ton, 3-axle options that start from 18,900 pounds.Payload Capacity: The payload changes depending on the trailer model:55-ton model: This one can handle up to 110,000 pounds.50-ton, 3-axle: It offers a 100,000 pounds payload.65-ton, 3-axle: This model supports a huge 130,000 pounds payload. This weight must be focused within a 12-foot section.Gross Vehicle Weight Rating (GVWR):The 50-ton, 3-axle lowboy has a GVWR of 120,500 pounds.I have seen some 40-ton versions rated up to 100,000 pounds GVWR.

Common Specifications and Features

Length: I find that trailers range from 46 to 53 feet. The length of the deck changes with each model, which impacts your cargo options.Width: Most trailers are 8.5 feet (102 inches) wide. This is a standard size for road travel without special permits.Axle Ratings: Each axle supports up to 25,000 pounds. This gives you a combined total of 75,000 pounds. Your trailer’s total capacity might be higher based on how the load is spread out.Suspension and Tires: Heavy-duty spring or air ride suspensions are what I recommend. Most use 255/70R 22.5 or 275/70R 22.5 radial tires. A 3-axle setup has 12 tires.Frame: I look for strong mainframes. They use 12″ to 16″ deep I-beams or structural channels. This design handles the strain of hauling heavy equipment.Brakes: They should have full air brake systems with spring parking brakes. I suggest getting a model with ABS for added safety.

Quick Reference Table: 3-Axle Lowboy Examples

Model/Capacity Empty Weight Payload Capacity GVWR Length
55-ton, 3-Axle 22,645 lbs 110,000 lbs ~132,645 lbs 53′

40-ton, 3-Axle 18,900 lbs Not listed 100,000 lbs 46′

What Affects 3-Axle Lowboy Weight?

  1. Trailer length and frame design
  2. The materials used for building it
  3. The suspension type and tire setup
  4. Any optional gear I add, like toolboxes or winches, increases the weight.

Based on my experience, if you haul very heavy machinery or large industrial parts, a 3-axle lowboy is a great choice. It provides the extra strength and payload you need. I always recommend you specify it correctly to meet all legal road limits.

4+ Axle Lowboy Weight

4 Axle Detachable Gooseneck Lowboy Trailer

From my experience, if you need to move the heaviest machinery, 4+ axle lowboy trailers are the best choice. These trailers are made to haul very heavy equipment. Their total weight can change quite a bit. It depends on the deck length, how many flip axles you have, and other features.

Category Details
Average Empty Weight of 4+ Axle Lowboys
  1. Base empty weight: 22,590 to over 26,850 lbs
  2. 53-foot, 55-ton triple axle lowboy: 22,645 lbs (26 ft deck, 53 ft total length)
  3. With a flip axle: Trailer about 24,000 lbs; with flip axle (2,850 lbs) total is 26,850 lbs
  4. Talbert 55SA-LD: 23,850 lbs (52 ft 6 in long, 26 ft deck)
Example 4+ Axle Heavy Haul Models

  2. Deck height (loaded): 18–24 inches
  3. Deck width: 8 ft 6 in (standard, suitable for extra-wide loads)
What Adds Weight to a 4+ Axle Lowboy
  1. Flip axles: Each adds about 2,850 lbs
  2. Deck length: Longer decks increase weight
  3. Detachable goosenecks: Stronger truck connection, increases total trailer weight
  4. Reinforced steel frame: Needed for higher GVWR and heavy hauling
Recommended Specs for 4+ Axle Lowboy Trailers
  1. Rated capacity: 55–60 tons
  2. Overall trailer length: 50–53 feet
  3. Weight (with flip axle): 24,000–26,850 lbs (empty)
  4. Deck width: 8’6”
  5. Deck height (loaded): 18–24 inches

A quick tip from me: These weights don’t include the load, taxes, or any optional accessories. The final numbers can change based on the maker and any custom features you add.Picking a 4+ axle lowboy shows you’re prepared for the biggest jobs and heaviest legal loads. I suggest you check the empty weight, flip axles, and frame details. This is important when you compare different models or get your permits ready.

Weight by Deck Length and Size

I’ve found that a lowboy trailer’s weight changes a lot with its deck length and overall size. Based on my experience, here are the key details to focus on if deck size is your main priority.

Common Deck Lengths and Their Impact on Weight

  1. Standard deck lengths are often in the range of 24 to 29.6 feet.
  2. The bottom well is the area between the gooseneck and the axles. I see it measure 24, 26, or up to 29 feet long. The standard width is 8 feet 6 inches.
  3. The largest models can have an overall trailer length of up to 53 feet.

How Deck Size Affects Empty Weight

  1. In my experience, a 35-ton lightweight lowboy trailer with a 24-foot deck weighs between 15,000 and 18,000 pounds.
  2. A triple-axle, 55-ton hydraulic gooseneck model is heavier. With a 26-foot deck and a 53-foot length, it weighs around 22,645 pounds.
  3. I’ve seen heavy-duty models for oversized loads with a 29-foot deck. These can weigh close to 40,000 pounds when empty.

Quick Reference: Lowboy Empty Weight by Deck Length

Deck Length (feet) Typical Empty Weight (pounds) Example Features
24 15,000–18,000 35-ton, lightweight, standard models
26 ~22,645 Triple axle, 55-ton, hydraulic gooseneck option
29 Up to 40,000 Oversize loads, multi-axle, heavy duty builds

Deck height remains consistent at 18 to 24 inches above the ground, even when the deck gets longer.Deck width is almost always 8.5 feet, which is the legal maximum for roads.A 29-foot bottom well at a standard width and height usually has a maximum payload capacity of 40,000 pounds.I suggest you watch for special features. Items like hydraulic goosenecks, extra axles, or reinforced frames will add to the deck length and the trailer’s total empty weight.Longer decks and higher tonnage ratings will always mean a heavier trailer. I recommend you compare lowboys by looking at the deck size, axle count, and special equipment. These features add considerable weight. Most standard lowboys with decks from 24 to 29.6 feet weigh between 15,000 and 40,000 pounds, based on their specific build.

How Material (Steel vs. Aluminum) Affects Weight

The material you pick for your lowboy trailer, either steel or aluminum, greatly changes the total trailer weight and how much you can haul.https://www.youtube.com/watch?v=NhRcjOC-Q80

Steel Lowboy Trailer Weight and Features

  1. Heavier build: In my experience, steel lowboys are much heavier than aluminum models. A steel trailer of a similar size will weigh 1,000 pounds or more than the aluminum version.
  2. Strong Frame: Steel trailers give you extra strength and resist bending. I recommend them if you need to haul on rough terrain or want a tough, super-rigid frame.
  3. Cost savings: Steel is cheaper to buy at first, which helps lower the initial price. You might spend more on maintenance later because of rust.
  4. Rust Issues: If you don’t choose stainless steel, these trailers can rust. This is a big problem in wet or snowy climates and means you’ll do more upkeep.
  5. Example: A standard tandem axle steel trailer can weigh 3,000 pounds. A similar aluminum trailer could be 1,000 pounds lighter.

Aluminum Lowboy Trailer Weight and Features

  1. Lightweight construction: Aluminum trailers weigh 30–50% less than steel ones. A standard tandem axle aluminum trailer might be around 2,000 pounds.
  2. Bigger Payload and Better Efficiency: Because they are lighter, aluminum trailers let you haul more cargo before you hit legal weight limits. They also improve fuel efficiency by putting less strain on your truck.
  3. Rust Resistance: Aluminum forms its own protective layer instead of rusting. I find this makes it perfect for humid, wet, or snowy areas. It requires less maintenance.
  4. More Payload Room: Saving 1,000 pounds or more on the trailer gives you that much extra capacity for your gear or equipment.
  5. Example: I’ve seen tandem-axle aluminum lowboys that are about 1,000 pounds lighter than a steel model with the same hauling capacity.

Steel vs Aluminum Lowboy Trailers: Quick Comparison

Feature Steel Aluminum
Weight Heavier (up to 2x more than aluminum) Lighter (by 1,000 lbs or more)
Payload capacity Lower (for same GVWR) Higher (more cargo before limit)
Durability Rigid, tough Pliable, easy to repair
Corrosion resistance Needs rust prevention No rust, needs minimal upkeep
Maintenance More maintenance required Less frequent maintenance
Fuel efficiency Lower Higher (tows easier)

My Take: Which Material to Choose?

I think aluminum is the way to go if you want to maximize your payload and save on long-term costs. This is true if you do frequent hauls or work in harsh weather. I’d suggest steel if your main goal is a lower upfront cost and the strongest frame possible. It’s also a good pick for rugged construction sites. Based on my experience, if you focus on efficiency and carrying the most cargo, aluminum lowboy trailers are the smart pick.

summary

Based on my experience hauling everything from small excavators to huge dozers, knowing your lowboy’s exact weight is critical. It’s not just about following the law. It’s also about keeping yourself safe and making a profit.This applies no matter what you drive. You could have a 15,000-pound steel trailer or a 40,000-pound aluminum one. That empty weight is the starting point for figuring out every single load. I suggest you weigh your specific trailer. Also, consider your materials and how your axles are set up. This way, you can stop guessing. I’ve found this knowledge pays for itself. It happens the first time you can carry the largest possible load without going over the limit.

FAQS

  1. Q: So, what’s the actual average weight of an empty lowboy trailer?
    A: Honestly, pinning down one “average” is tricky in my experience. Basic single-drop steel lowboys I’ve hauled start around 12,000-15,000 lbs (5,400-6,800 kg). But step up to a heavy-duty triple-axle with extendable decks and hydraulic ramps, and you’re easily looking at 18,000-25,000 lbs (8,200-11,300 kg) or even more. The materials, length, axle count, and features massively swing the scale. Always check your specific trailer’s VIN plate or documentation for its exact tare weight.

  2. Q: Does an aluminum lowboy trailer weigh a lot less than steel?
    A: Aluminum can save significant weight – sometimes 2,000-5,000 lbs (900-2,270 kg) less than a comparable steel trailer, based on models I’ve compared. This means more payload capacity under your GVWR. But here’s the catch: Aluminum lowboys often need beefier construction in key stress areas, potentially offsetting some savings. Plus, aluminum ramps or decks might not handle the same brutal abuse as steel. Don’t assume it’s always lighter; get the actual specs for the model you’re eyeing.

  3. Q: Why does knowing my lowboy’s empty weight matter so much?
    A: Because that tare weight eats directly into your legal payload limit! Let me break it down simply: If your truck + lowboy combo has a Gross Vehicle Weight Rating (GVWR) of 80,000 lbs, and your lowboy alone weighs 20,000 lbs, you’ve only got 60,000 lbs left for your cargo before factoring in the truck and fuel. Miscalculating this is how you end up dangerously overloaded and facing hefty fines at the scales. Your lowboy’s weight is the foundation of every load plan I make.

  4. Q: How do I find out the exact weight of my specific lowboy trailer?
    A: Never guess – get it certified! The gold standard is taking your empty trailer to a CAT Scale or certified truck scale. Weigh it hooked to your truck, then weigh just the truck, and subtract. Second best: find the manufacturer’s VIN plate or specification sheet – it lists the official tare weight. Remember, added features like toolboxes, generator sets, or extra hydraulic systems you installed after purchase add weight not on the original spec! I make it a habit to re-weigh mine every few years.

  5. Q: Can I estimate my lowboy’s weight based on size or axles alone?
    A: You can get roughly in the ballpark, but trust me, it’s a gamble. While a 2-axle lowboy is generally lighter than a 3-axle, construction materials (steel vs. aluminum vs. hybrid), deck thickness, detachable neck design, ramp type (steel vs. aluminum, hydraulic vs. manual), and even the subframe design cause huge variations. I’ve seen two nominally identical 40-foot trailers differ by over 3,000 lbs due to build specs. Relying solely on axle count or length for critical weight calculations is asking for trouble at the weigh station. Get the real number.
