Trampoline frames are the easiest quality to overlook as they are covered and difficult to see in the finished product. They are also one of the most crucial elements in the end performance of the product. As a user lands on the jump surface, the energy is dispersed into the springs and the force attempts to draw the frame inward. Under-built frames or frames broken into too many sections provide flex and sag under these demanding situations. Any movement in the frame results in a loss of energy and a decrease in performance.
Every spring on a trampoline adds to the amount of preloaded force that a trampoline frame must withstand. With 228 springs, the worlds largest trampoline uses 6 oversized and reinforced frame sections to withstand the spring tension. Six 1-piece legs hold the 650 pound behemoth off the ground.
Unlike other manufacturers, we don’t put holes in our trampoline frames for spring hook up.
Why not?
- So that we don’t remove steel from frame, creating a structurally weaker frame
- So that we don’t create an entry point for moisture, which leads to rust
- So that we don’t cause frame stress. With holes, all tension is directed to the top of the frame. This puts stress on the steel to roll inward, off the collar joints where the legs attach, which can cause a high tendency for weld fractures in leg collars
- So that we don’t cause unnecessary wear. With holes, springs sit between your frame & pad that increases wear on both springs & padding, which in turn decreases performance.
