How does the SPINE hinge work?

There are 5 working SPINE vertebrae constantly interacting seamlessly with each other to create a 90 degree hinge opening. As every element helps the other to take the strain, they rotate only 18 degrees meaning they share the load, making wear from friction virtually non-existent.

A spun wire cable is the heart of the SPINE hinge and is produced by the leading manufacturer in the world. It’s diameter is a mere 0.60mm and at full tensile strength can hold over 300kg.

The dual springs not only provide the pulling power of SPINE, but they allow the articulation of the vertebrae and enable our unique auto-shut mechanism.
