A drawbar spring is a type of extension spring with a number of uses in households, commercial settings, and even automobiles. They come in prefabricated styles, but we also specialize in made to order springs of any type for just about any imaginable use.
A drawbar spring is a type of extension spring, which means there are spaces between the spring's coils, allowing it to expand and contract as it handles a load. The main feature separating a drawbar spring from other types of extension springs is the long, steel loop at one end, which passes through the center of the spring's coils and hooks at the other end. Thus, the spring compresses when a load is applied. You can find these in numerous applications, including porch swings.
A drawbar spring is a practical choice in applications calling for backup safety. Due to the design of drawbar springs, even if the spring should fracture and break, the looped steel through the center of the spring continues to maintain a static load. Thus, if you have an application in which an overload is a concern, a drawbar spring will undoubtedly provide an extra layer of safety. They are common in manufacturing facilities in which springs carry large loads; if the spring would happen to break, the load will not fall and break or injure someone nearby. In order to increase the lifespan of these springs, it is important to lubricate them frequently.
Although hundreds if not thousands of prefabricated springs are available on the market today, engineers, developers, inventers, and even craftsmen often require made to order springs that suit their unique needs. Different types of springs offer different features and things like the chosen material and wire gauge impact the operation of the spring, the load it carries, and even its lifespan. Of course, some materials are more expensive than others are, so it is important to choose a material that suits your budget as well as your needs.
We are an industry leader when it comes to made to order springs of all types, whether you need compression, extension, or even torsion springs. We take your measurements carefully and work closely with you to create one or even thousands of springs that suit your unique needs. Made to order springs can certainly become expensive, and although you may be able to fabricate a single spring that suits your needs on your own, it is difficult without the right tools and expertise. We are always available for consultation, and we will help you determine the right materials, spring types, and even wire gauges for your unique application.
Whether you need one or more drawbar springs or you are in the market for other types of made to order springs, we are always happy to assist you. With the right equipment, knowledge, and expertise, we can help you with any design or application imaginable.
