How Much Weight Can A House Trailer Axle Hold? [4 Types of Axle Weight Capacity And Risks If You Avoid It]




Key takeaways:

  • Axles are rated based on their diameter, and thicker axles can carry more weight.
  • Trailer house axles can typically handle anywhere from 1,000 to 10,000 pounds, depending on their bearing size.
  • Different types of axles, such as single, tandem, triple, and spread axles, have varying weight capacities.
  • Overloading a house trailer axle can lead to axle damage, tire blowouts, poor handling, brake issues,  damage to roads, and legal problems.
  • To avoid overloading, it’s important to balance the weight distribution, keep within axle and trailer weight limits, and be aware of your truck’s towing capacity.

Trailer axles are stronger than mobile home axles. But that doesn’t mean you just put heavy loads on it. Because it has weight limits too. Just like there are differences in how much weight can mobile home axles hold.  You just put heavy loads on your trailer and expect your trailer axle to be right. So, how much weight can a house trailer axle hold?

How much weight can a house trailer axle hold

Well, it depends on what type of axle you are using. But in general, up to 1,000 pounds can be carried on a 1.5-inch diameter axle. And a 1.75-inch diameter axle can carry up to 2,000 pounds. So, it actually depends on the size of the axle. Knowing the weight capacity also determines if you sleep inside an enclosed trailer or not.

How do you know which size axle you need? And weight capacity according to axle size? That’s what I’m going to disclose in this blog. So, keep reading to get the perfect idea.

How Much Weight Can A House Trailer Axle Hold?

How much weight can a house trailer axle hold? So, the mobile homes or house trailer’s weight limit is basically the axle’s load rating. They size up these axles based on how thick they are, which tells you how strong they are. The thicker the axle, the more stuff it can carry – simple as that. These axles usually handle anywhere from 1,000 to 10,000 pounds.

It’s important to know how much your trailer can handle so you don’t go overboard and break something. If you try to haul more than your trailer’s limit or load things all wonky, you’re asking for trouble. If that additional axle breaks while you’re loading up, you’re in for a world of frustration, not to mention the risk of hurting yourself and others. So, have a clear idea of the axle weight limit before jumping into loading them.

How Can You Determine The Weight Capacity Of Your House Trailer Axle?

Determine The Weight Capacity Of Your House Trailer Axle

So, knowing how much weight can trailer house axle carry is a must. But how do you determine the capacity of mobile homes or house trailers? No worries, there is a way. You can use a formula and have an idea of weight capacity. Now, don’t run away thinking it’s like a math problem. It’s kind of like that but not so complicated like that. Let’s break it down simply for you.

For example, if you’re eyeing a 20-foot trailer, you do the math – 20 feet times 500 pounds per foot gives you 10,000 pounds on the low end, and 20 times 550 gives you 11,000 pounds on the high end. So, it’s a good idea to go for a trailer with an axle capacity of 12,000 pounds or more. People often go a bit overboard and get a 14,000-pound capacity trailer for a 20-footer just to be safe.

Now, if you’re thinking of a wide 10-foot or even an oversized 11-12-foot trailer, you have to use a different formula. It’s 59 pounds per square foot of trailer deck. For example, if you’re looking at a 40-foot by 10-foot gooseneck, that’s 400 square feet. So, 400 times 59 gives you 23,900 pounds, which is more than the 21,000-pound GVWR.

In this case, it’s smart to go for a 28,000-pound GVWR with four 7,000-pound mobile home axles or trailer axles. Of course, the final weight depends on your design and materials. You need to know this even if you want to make tropical roofs for camper trailers.

But if you know the math clearly, then this formula, you know about  how to tell the weight capacity of a trailer axle. But it’s usually better to “buy more trailers than you need.” Trust us. It’ll save you a lot of headaches in the long run. We know all about counting every pound in our own tiny house.

What Factors Affect The Maximum Weight A Trailer Axle Can Hold?

Calculating can’t give an idea, but it can decide the weight capacity. But it depends on many factors, such as:

  • Axle Type: Different axles they’re not all the same. Like, single axles can’t handle as much weight as tandem or triple axles. They’re like the little siblings of the axle world. Just like you can’t use mobile home tires on a trailer, you can’t expect all axle weight capacity to be the same.
  • Axle Material and Design: What the axle is made of and how it’s put together makes a big difference in mobile homes and house trailers. Strong, heavy-duty materials and smart designs can carry more weight without breaking a sweat.
  • Axle Rating: The folks who make axles give them a rating. It’s like their weight limit, and you don’t want to mess with it. You’ve got to know that rating to figure out how much your trailer can haul safely.
  • Tire Capacity: Tire size is a big deal, too. They’ve got to match or be even better than what the axle can handle. You don’t want your tires giving up on you when you’re on the road.
  • Suspension System: The way your trailer bounces and sways is all about the suspension system. It can spread out the weight and make sure your axles handle it like a champ. A solid suspension is your buddy when it comes to carrying heavy loads.

Different Types Of Trailer Axles With Varying Weight Capacities

As you know, the different axles have different types of weight capacities. Although, the market is filled with various types of axles. Just like if you ask about how much weight can a double axle car trailer hold, then the answer will be different.  So, let’s break down some of the most common axle types:

Quad axles

Quad axles are handy when you need to take your heavy truck or semi-trailer off the beaten path, especially on soft, mushy ground like lug axles. Now, most of the time, those non-powered axles are what they call “lift axles,” but sometimes they’re not.

When they are lift axles, you’ve got two regular axles in the back and two lift axles up front. And here’s the cool part: if your semi-trailer isn’t hauling much, or nothing at all, you can hoist those front lift axles up with these pound axles. This does two good things – it saves on fuel, and it keeps your tires from dragging and wearing out unnecessarily. So, quad axles are the way to go in some situations.

Tandem Axles

Alright, so most semi-trailers roll with these tandem axles, which is just a fancy way of saying they have two sets of lug axles lined up one after the other. These axles are buddies, hanging out about 5 feet apart, and they come with some nifty advantages like pound axles.

You see, tires can take a beating now and then. But with tandem axles, you’ve got a backup plan. When one tire gets grumpy and starts acting up, the other one steps in to help out. It’s like having a buddy who’s got your back.

And these axles are no slouch when it comes to spreading the load. With more axles in the mix, your cargo gets spread out over a bigger chunk of the trailer’s frame. That means less stress on your trailer and more peace of mind for you.

Spread Axles

So, you’ve got these spread axle trailers, and they’re kind of unique like lug axles. See, the deal with them is that they have single axles, and they’re spaced out quite a bit, at least 10 feet apart. This setup gives them some flexibility, but it’s not all sunshine and rainbows because they’re pretty tough on their tires.

The thing with these spread trailer axles is that each one gets to do its own thing. It’s like they’re on a solo mission. And guess what? A single axle can handle a hefty 20,000 pounds. So, when you’ve got a spread axle, you’re looking at the potential to carry a whopping 40,000 pounds. That’s a lot of leeway when you’ve got a heavy load to haul.

Triple Axles

This third axle is pretty handy when it comes to carrying a heavy load and making sure you don’t get stuck in soft, squishy ground. You know, like when dump trucks are on their way to a construction site, they might lift up that third axle to make life easier. But when they need to cross lawns or soft soil, they drop it back down. It’s like a superhero move for trucks.

And the same goes for those beefy semi-trailers that need to carry a whole lot of stuff. They use these third rear axles to spread out the weight over more pound axles. This helps them play by the rules of the road and stay within weight limits. Plus, it’s a real lifesaver when they’ve got to navigate through tricky, soft terrain. So, these third axles are like the secret weapon that keeps the load weights moving.

What Are The Risks Of Overloading A House Trailer Axle?

Not sure about how much weight can a 6×10 single axle trailer hold? And you are messing with overloading a house trailer axle? Bad news. I’m telling you, all those weight capacities aren’t for no reason. Here’s what can go wrong if you ignore those limits:

The Risks Of Overloading A House Trailer Axle

Axle Damage: You push too much weight on it, and the axle could give up, bend, or break. It’s like asking your little cousin to carry your backpack full of bricks.

Tire Trouble: Those tires, they’re not invincible. Overloading the axle can blow out your tires, and that’s a hassle on the road. If that happens, then electric brakes won’t work either. Which will lead to accidents.

Poor Handling: Your trailer’s balance goes out the window. It’s like trying to ride a bicycle with a wobbly wheel. You can’t control it, and that’s dangerous.

Brake Problems: Overloaded axles put more strain on the electric brakes. Electric brakes might not work right when you need them to, and that’s a recipe for disaster.

Legal Issues: Forget the fines and headaches. Overloading is against the law in many places. You don’t want to be on the wrong side of the law while hauling your house down the highway.

So, be smart and keep it within the limits. Don’t mess with an overloaded house trailer axle; it’s just not worth the trouble.

How Can You Safely Load Your House Trailer To Avoid Overloading The Axle?

How Can You Safely Load Your House Trailer To Avoid Overloading The Axle

Now you know all about weight capacity. So, now you can load your house trailer, right? Yes, but wait a minute. You know the weight capacity, but you need to know how to distribute that load perfectly. Because the wrong distribution can lead to some accidents. You’ve got to spread that weight around, right? Here’s the how:

  1. GAWR: Each axle on your trailer has a limit. It’s called the GAWR (Gross Axle Weight Rating). If you’ve got two axles, you’ll have one for the front and one for the back. It’s also in mobile home tires vs trailer tires. Don’t go over this limit, or you’re asking for trouble.
  1. Front-Back Balance: Aim to keep about 60% of your load in the front half of your trailer. Don’t go crazy at the back; it could mess up your trailer and make driving a nightmare. Try to keep the total weight (that’s your trailer and the stuff in it) to about 80% of the maximum limit. It’s all there on your trailer’s VIN label.
  1. Left-Right Balance: Don’t forget about the left and right sides. Balance your load so you’re not lopsided. It’s good for your trailer and your driving skills.
  1. Truck Capacity: Your truck has a limit, too. It’s called the GVWR (Gross Vehicle Weight Rating). Don’t go past that, or your truck might not be very happy.
  1. Hitch Check: Even your hitch has a limit on how much it can handle. If you put too much weight on it without a heavy-duty hitch, you’re risking a hitch disaster and a big accident.

So, make sure you’re spreading that load smartly. Don’t mess around with the limits; it’s a recipe for trouble on the road.

So, it’s not all about axle capacity. Sometimes it’s about laws, too. Just like pulling a trailer behind a camper becomes a legal issue, it is the same with weight limitation, too. Some states get very annoyed with this weight limitation. And not maintaining those can get you in trouble. You definitely don’t want that, right? Here are some rules you need to follow. Here’s the deal:

  1. Gross Vehicle Weight Rating (GVWR): Your trailer has this number, and you can’t go over it. It’s like the ultimate limit set by the manufacturer.
  1. Gross Axle Weight Rating (GAWR): Each axle on your utility trailer has a maximum weight it can handle. Don’t push it past that limit.
  1. State and Local Laws: Different places have their own rules. Some states have specific axle weight limits you should stick to.
  1. Tire Load Ratings: Don’t forget about your tires. They’ve got a limit too. Check what’s stamped on them, and don’t exceed it.
  1. Hitch Capacity: Your hitch has a maximum weight it can handle. Don’t go overboard or risk breaking it.
  1. Truck’s Towing Capacity: Your truck has limits too. Make sure you’re not towing more than it can handle.

So, the legal stuff is there to keep everyone safe on the road. Don’t mess with it, or you might end up with fines, trouble, and a real headache. Stick to the rules, and you’ll be in the clear.
