To Maximize Springs’ Function

Springs for mining and heavy equipment are exposed to extremely harsh conditions such as repeated heavy load and long-term vibration. Based on the applications of the springs, Tokai Spring has the practical know-how of design standards, manufacturing control, and product inspection.

3. Flexibility In Designs

When considering springs for mining and heavy equipment that require various design conditions and specification requirements, it is not always possible to achieve the optimum proposal by considering only coil spring. However, At Tokai Spring, we are capable of handling all types of springs such as disc springs, volute springs, and torsion bars and therefore, have a great deal of flexibility in designing the perfect spring.

Why ONLY Tokai Spring?

We can manufacture coil springs with a maximum wire diameter of φ90 mm, disc springs with a maximum material thickness of 40 mm, and volute springs with a maximum material thickness of 35 mm. All of these are the largest in the world. In addition, we always keep a stock of large-sized materials, so even such enormous springs can be delivered in a very short lead time.
We have the design know-how and a manufacturing system that can provide springs with a large load for these industries. This is why only Tokai Spring can provide the best springs and services to clients in the mining and heavy equipment industries.
