We once owned a trampoline that had ninety six springs.
It had great bounce, but the springs regularly had to be replaced.
So, why do trampoline springs wear out and need to be replaced? The things that make springs wear out include moisture, rust, too much weight, too much pressure, and changing your springs around to get more bounce.
Read on to figure out how you can protect your springs so you do not have to replace them regularly.
Why do springs give a trampoline bounce?
The springs are really the key to the trampoline.
But over time, springs wear out.
That is why some companies have tried to improve on the idea of the spring, including Springfree Trampolines.
The basic idea behind the springs is that when you bounce on the mat of the trampoline, the springs extend out as far as they can.
Once they have extended as far as they can, they then retract.
So while the extending allows the mat to bend, the retracting pulls the mat tighter, which in turn gives the motion of throwing the jumper into the air.
When you are in the air, you eventually land back on the trampoline mat.
And then the process starts all over again.
The expanding and retracting of the springs is what gives you the bounce you get on the mat.
This is why the life of the springs is so important
Without good springs, you will not get the expanding and retracting motion that gives you the bounce.
When the springs get rusty or are left in their expanded state, they do not work as well as they should, and you do not get the bounce you want from your trampoline.
What makes springs wear out?
There are a few things that make springs wear out, and if you are careful, you can do things to avoid wearing out your springs.
Moisture and rust
Springs are typically made of galvanized steel, which makes them very strong.
But just like any other metal, they can get ruined if they are exposed to the outside elements for long periods of time.
Moisture is one of the elements that can ruin your springs quickly.
When steel is exposed to rain and moisture, it can quickly rust and rusted springs will not give you a good bounce.
The rust on the springs will either not allow the springs to expand and retract or it will expand and retract more slowly until the spring is no longer any use.
Rust also makes the springs more brittle, so they are more likely to fall apart and break.
How to avoid moisture and rust
There are a few things you can do to avoid getting moisture on your springs and having them get ruined.
The first thing you can do is apply WD40 to the springs.
WD40 has been used for years to help metal from getting rusted or door joints from making noises.
Apply some WD40 onto your springs when you know harsh weather is coming to protect the springs from rain and wind.
The second thing you can do is purchase a trampoline safety pad for the springs of your trampoline.
The trampoline safety pad will give you a nice cover for the springs so they will be protected from outside conditions.
Too much weight
Springs can only take so much weight before they start wearing out.
If a trampoline is taking on too much weight, the springs will begin to deteriorate and will not last as long.
Each trampoline you choose from is going to have a weight limit assigned to it, because of both what the mat can take and also the springs.
Typically the weight limits on regular, full-sized trampolines are up to 250 lbs.
Trampolines that are rated for more weight can be purchased, but they are going to be significantly more than regular trampolines.
You can find trampolines that are rated for more weight, including Acon Air, which is rated for 800 lbs.
Springfree Trampolines are rated for a maximum capacity of 1100 lbs but suggest a per jumper weight of 220 lbs.
Each cost more, so something to consider when you are purchasing a trampoline.
How to avoid too much weight
It is recommended that one person jumps on the trampoline at a time.
This is for safety reasons, but it also because putting too much weight on the trampoline can ruin the different parts of the trampoline.
This is also the same for the moves that you make on the trampoline.
Doing things like backflips or front flips on the trampoline puts too much weight on the springs and causes them to stretch past their limit.
When you do flips, you fly higher into the air, meaning more pressure, and the weight comes back down onto the trampoline, causes the springs to extend past where their typically would.
So, if you want to avoid replacing your springs all the time due to weight, make sure to follow the rules of one person at a time and no flipping.
Too much pressure
It is fun jumping around the trampoline.
Sometimes we are tempted to jump around the outside of the trampoline for a different experience.
My kids love to jump around the outside of the trampoline while laughing about how their brother cannot catch them.
Jumping around the outside of the trampoline can feel pretty normal as well.
But it can also put too much pressure on the springs.
Trampolines are set up so that the mat takes most of the weight in the middle of the trampoline.
When you jump in the middle of the trampoline, the springs expand to adjust to the weight being put on the middle of the trampoline.
When you jump on the edge of the trampoline, though, you are putting most of that weight and pressure on just a few springs around where you are jumping.
So instead of all the springs expanding, just a few are.
And that puts a lot of strain on just a few springs.
How to avoid putting too much pressure on the springs
As discussed previously, make sure that only one person is jumping on the trampoline at a time.
Also, make sure that whoever is jumping jumps in the middle of the trampoline.
Changing your springs around
People are always looking for more ways to get more bounce out of their trampoline.
One of the simplest ways to get more bounce is to replace old springs.
But a more popular way is to take off your springs and put them back on in different configurations.
For example, some people have suggested putting your springs on in an X pattern, meaning you are crossing two springs over each other.
Another suggestion is putting your springs in a V pattern, coming out from the trampoline.
This might give you more bounce to the trampoline, but it takes more of a toll on the springs and wears them out quicker.
Avoid changing the springs configuration
If you want your springs to last longer, keep them the way they normally are, one spring for one hole.
Crossing the springs will wear them out quicker.
ImproveSummer.com summarizes it the best:
Do trampoline springs wear out? Yes, they do and after you using your trampoline for a while they can go bad. The only way to tell if your springs are bad and need replaced is to visually inspect them. Here’s what you’re looking for:
1. signs of rust
2. broken or sheared off springs
3. overstretched springs that don’t return to their coiled position
If you notice any of those things in any of your trampoline’s springs, then it means that they are bad. And yes, you need to replace them right away.Trampoline Springs: When Are They Bad & When Should You Replace Them? | Improve Summer
So check your springs regularly, cover them in WD40 when needed, replace any rusted springs or any that can no longer extend and retract, and avoid crossing your springs in an attempt to get more bounce.
