Heavy Duty Extension Springs
Premier provider of custom heavy-duty extension springs for various industries.
We specialize in the manufacturing of heavy-duty extension springs, designing, engineering, and producing millions annually to meet customized requirements.
With our expertise as expert heavy-duty extension spring manufacturers, our springs are utilized in a wide range of applications across industries such as construction, robotics, lifting equipment, agriculture, elevators, heavy machinery, and specialized equipment.
Understanding Heavy-Duty Extension Springs
They consist of tightly wound coils that enable external forces to create tension through end fittings or loops. This tension is utilized to bring components back together as the spring returns to its original extended shape.Within our division, we focus on heavy extension springs, which represent the largest category within the extension spring family.
As suppliers of heavy-duty extension springs, we specialize in designing and manufacturing these springs not only in the China but also globally, catering to a diverse array of industries and applications.
How do extension springs function?
Extension springs, also known as tension springs, bear similarity to compression springs but differ in the direction of load – they operate using a tension (pulling) force instead of a compression (pushing) force, leading to deflection through an end fitting.
These extension springs serve as connectors or attachments linking two components, pulling them together when external forces try to separate them. For instance, an extension spring could be utilized on a trampoline to fasten the mat to the frame while imparting the necessary tension for the trampoline to achieve its characteristic bounce. A higher-rated extension spring can provide more energy and bounce compared to a lower-rated one.
Varieties of extension springs and attachments
The most common and cost-effective design for extension coil springs features hook ends or loops integrated with the spring body, matching the body’s diameter. Customers can choose from various end loops, hooks, and other mechanical attachment options to suit their specific needs.
- EXTENSION SPRING WITH GERMAN LOOPS
- EXTENSION SPRING WITH HALF HOOKS
- EXTENSION SPRING WITH ENGLISH LOOP
- EXTENSION SPRING WITH EXTENDED HOOKS
- EXTENSION SPRING WITH SIDE HOOKS
- EXTENSION SPRING WITH SIDE LOOPS
- EXTENSION SPRING WITH SCREW PLUGS
- EXTENSION SPRING WITH CREW SHACKLES
Extension springs featuring round-end hooks and V-hooks are among our most sought-after products, but we also offer a range of other options such as extension springs with extended eyes, loops, and swivel hooks to cater to diverse applications.
Top-quality materials for heavy-duty extension springs
We maintain the world’s largest inventory of chrome silicon and collaborate with carbon steels, low and high alloyed steels to ensure our engineers can select the most suitable material for your extension springs based on the specific application and working conditions.
In the realm of industrial extension springs, critical factors to consider for the material include chemical composition, surface characteristics, tensile strength, and wire diameter. Our team of material scientists are experts in their field and work closely with our engineers to assess the properties of all the metals we use:
