What requirements should good metal springs meet?
You use a trampoline mainly when the weather is nice. But a trampoline is outside all year round, even if it is not so good weather. Even though you have a cover, the feathers get a lot to endure. In addition, a sprung spring stretches with each jump, after which it then springs back again. This keeps him unaffected. The average life span of a spring is about 2 to 3 years. Fortunately, they are for sale per brand and type in sets. Do not wait too long to replace rusted, missing or broken trampoline springs. Because the others are overloaded, there is a chance that several will be damaged.
When the trampoline is used with some regularity, you can not escape that the trampoline loses its ability to jump. But what determines the jumping force? Well, the springs. They determine for the most part the suspension of the trampoline. The longer the springs, the smoother the jumping result. Long feathers from 21 cm have a longer stretch and therefore jump more smoothly. Short feathers from 14 to 18 cm are somewhat stiffer which results in a somewhat harder suspension. But not only the length is decisive for the springy character of the trampoline. Does the trampoline have too few springs? Then you burden them too much. Too much is not good either. The trampoline then barely springs, which is not so comfortable for the person jumping.
Jumps are available in many shapes and sizes. Do you want to know the size of your spring? Then remove an old one from the frame and the mat. Is he stretched? Then he needs to be replaced. To know the size, measure the unstretched shape of the trampoline spring including the hooks. As long as the size matches, he always fits your trampoline, no matter what kind of feather you choose.
Kind of feathers
The durability of trampoline springs is more than the number and the length. The kind also plays a major role. We make a distinction between conical and non-conical springs. The conical variant decreases towards the ends in thickness. When stressed, he stretches first in the thicker part and then only in the thinner part at the ends. The result? Smoother jumping. With the non-conical variant, the beginning and end of the spring quickly expand. Do you want the best quality? Always go for conical springs. You do not have anything to do with a trampoline spring that rusts quickly. Therefore choose galvanized springs. These are covered with a layer of zinc to prevent rust.
Good springs are an important investment for your trampoline because they determine the jumping force for the most part. Whether you opt for expensive or cheap feathers, when using the trampoline intensively you can not escape stretching them. How fast that happens depends on its quality. The best trampoline springs are conical and galvanized. Replace the springs of the trampoline and he is alive again.
