Abstract
A trolley magnetic braking system having a brake block assembly engagable by a trolley, a substantially stationary conductor that is pitch adjustable and a carrier having magnetic members that are driven along the conductive member for braking a trolley. Providing a pitch adjustable conductor allows for modification of how much of the conductor interfaces with the magnets and therein varying the amount of eddy current applied in the braking apparatus.
Claims14
A braking system in combination with a trolley and a zip line, the braking system utilizing eddy currents to slow down and stop the trolley advancing on the zip line, the combination comprising:
- a) a brake block assembly disposed proximal the stopping area of the zip line;
- b) a stationary elongate conductor plate;
- c) a magnet carrier assembly having opposing magnetic fields disposed therein;
- and
- d) a magnet carrier support track for guiding the travel of said magnet carrier along said conductor plate;
- e) wherein said magnet carrier support track further comprises a pair of support posts located thereon for retaining said conductor between said ma net during the movement thereof;
- and
- f) wherein said support posts further include means for adjusting the pitch of said conductor to increase and decrease the surface area interfaces with the magnetic fields in said magnet carrier thereby enabling a user to manipulate the eddy current effect and the resultant drag.
