The technology in most of our devices is our patented eddy current magnetic braking. Eddy currents are created when non-magnetic metals move through a magnetic field.
Induction braking uses a phenomenon known as electromagnetic induction, where the movement between a magnet and a nonmagnetic metal causes a magnetic force opposing the movement between the two objects. This creates kinetic energy (movement is converted into thermal energy) in the form of heat . This braking is done entirely without contact. When the conductive material in the magnetic field is stationary no reaction occurs, but when the driver moves in the magnetic field an eddy current is generated, which creates the braking effect.
It is called an 'eddy current' ( literally vortex flow ) because the current does not flow in a straight line but swirls like vortex currents in a river.
In our devices, a retraction spring rewinds the webbing in the device. When the webbing is pulled out of the device by force, aluminum rotors rotate in the magnetic field and creates the eddy current. This current controls the braking force and the speed at which the rotation takes place, which in turn controls the speed at which the webbing unfolds.
Our induction braking system is self-regulating. This means that the braking resistance is adjusted automatically to provide comfortable braking for a wide range of rider weights.
The magnetic braking technology in our devices has many advantages, including:
The system has no contacting parts, which means there are no components such as brake shoes to wear out or break. Therefore, there is less maintenance and lower operating costs for our devices.
The braking system automatically adjusts to a wide variety of rider weights, so children and adults of all sizes have a similar, enjoyable experience.
Whether for free fall jumping, slowing a descent or approaching a platform, the devices are easy to use and the experience is smooth and comfortable.
