Our Technology

Head Rush is the only company to use magnetic eddy current braking technology in climbing, free fall, and zip line devices, and the difference shows. Our eddy current brake technology is extremely reliable, smooth, and low maintenance. The braking is friction-free with no contacting parts.

Benefits of Magnetic Eddy Current Braking

Low MaintenanceBecause the braking is magnetic there are no contacting parts in the braking system to wear out or fail. Magnetic braking is low maintenance and extremely reliable.

Self-RegulatingThe braking resistance adjusts automatically to the weight of the participant so our devices can accommodate a wide range of weights, and children and adults alike have a consistent experience.

Best User Experience Climbers love the smooth descent, jumpers love the soft catch, and zip line riders love the hands-free braking with Head Rush devices.

How Does it Work?

TechnologyThis video explains the science behind our patented magnetic eddy current braking and how we implement this technology in our devices.

Eddy Current Braking Demonstration This video will show eddy current braking in action and is helpful in understanding how our technology works.

How is eddy current braking used in Head Rush devices?

When the webbing is pulled out of a Head Rush device by a participant’s weight, centrifugal force sends aluminum rotor arms spinning into the magnetic field of stationary magnets within the device. The movement of aluminum past magnets creates the eddy currents within the aluminum arms.

Eddy currents are circular electrical currents, named because they flow like eddies in a river. The force of the eddy currents opposes the force of the magnets, therefor providing resistance and slowing the release of webbing from the device. Want to dig deeper? Take a quick physics lesson to learn more about the science behind magnetic braking.

Our braking system is self-regulating, meaning it adjusts automatically based on the participant’s weight. A heavier participant will pull the webbing out at a faster rate, causing the rotor arms to move faster and move further into the magnetic field to create increased braking force. This allows a wide range of weights to enjoy a similar and consistent experience with Head Rush devices.
