The springs on a big trampoline are the fundamental engine of the bounce, and their quality, quantity, and design are paramount to the performance, safety, and longevity of the entire unit. JYTrampoline springs are engineered from high-carbon steel, chosen for its excellent tensile strength and ability to return to its original shape after thousands of compression cycles. The length and gauge (thickness) of the spring are carefully calculated based on the trampoline's size and intended bounce feel. Longer springs generally provide a more powerful and softer bounce, as they have a longer travel distance. The number of springs is equally critical; a higher spring count distributes the jumper's weight more evenly, resulting in a more responsive and controlled bounce across the entire mat surface. Over time, springs will naturally wear out and may lose tension or even break, leading to a degraded bounce and creating potential safety hazards if they puncture the padding. Therefore, we recommend inspecting springs periodically and replacing them with genuine JYTrampoline springs when signs of wear appear. Using OEM springs ensures perfect compatibility in terms of length, hook design, and tensile strength, maintaining the trampoline's original performance and safety characteristics. Understanding the vital role of these components highlights why they are a key area of focus in our manufacturing and a critical part of long-term trampoline maintenance.
