Drawbar Springs
Drawbar springs are compression springs that are excellent for use in potential overload situations and offer a built-in safety feature that, upon fracturing, will continue to carry a static load. In a drawbar spring, the load is applied at the ends of long steel loops which pass through the spring’s center and are hooked around the opposite end, thus compressing the spring upon loading. A common application of the drawbar spring is used when supporting a porch swing.
