Coming soon, the quickJump Free Fall Device!

The quickJump Free Fall Device is manufactured by Headrush Technologies. The free-fall simulator is based upon the award winning eddy current magnetic braking technology to provide an exciting "free fall" experience. The quickJump can be used in a variety of applications, including platform egress and a "leap of faith."

From a height you take that leap of faith, as you free fall towards the ground the quickJump kicks in to slow your descent for a smooth landing, but not before you feel the breeze in your hair and the butterflies in your stomach.


About the technology

What are eddy currents?
Eddy currents happen when you move non-magnetic metals through a magnetic field

What is eddy current braking?
Eddy current braking uses a phenomenon called electromagnetic induction, where motion between a magnet and non-magnetic metal to causes a force opposing the motion between the two objects.  As a result, kinetic energy, which is movement, is converted to thermal energy, which is heat. This braking happens entirely without contact.  When the conductive material in the magnetic field is still, no reaction occurs.  When the conductor moves while in the magnetic field, a magnetic field and eddy currents are generated within the conductor that opposes the direction of the current of the magnetic field of the permanent magnet to create the braking effect.  This is called an “eddy current”, because the current doesn’t travel in a straight line. The induced current swirls within the conductor, like eddy currents in a river.

How is eddy current braking used in our devices?
In our devices, a retraction spring winds the webbing into the device.  When force pulls the webbing out of the device, aluminum rotor arms are sent spinning into a magnetic field.  This creates the eddy currents.  These currents control the braking force and, thus, the speed at which the spinning occurs.  In turn, controlling the speed at which the webbing comes out.  Our eddy current braking system is self-regulating.  This means that the braking resistance automatically adjusts itself to provide consistent braking across a wide range of participant weights.

What are the benefits of eddy current braking in these devices?
There are many benefits of incorporating eddy current braking into our devices.  Our devices are:

  • Low maintenance – Because the braking is magnetic, there are not any contacting parts in the braking system.  There are no components, such as brake pads, to wear out of fail.  As a result, there is less maintenance and a low ownership cost for our devices.
  • Self regulating – Because the braking system is self regulating, our devices can accommodate a wide range of weights.  Children and adults alike have a consistent experience.
  • Smooth and comfortable – Whether jumping, descending or approaching a platform, the experience is smooth and comfortable
