A slip ring is a rotary coupling used to transfer electric current from a stationary unit to a rotating unit. This is accomplished by either (1) holding the center core stationary while the brushes and housing rotate around it, or (2) holding the brushes and housing stationary while the center core is allowed to rotate.
Duro cord reels take advantage of both scenarios. Depending on the need, we can provide our customers with a cord reel that is right for their application. Whether it be an overhead crane that would need power while in motion or for a building contractor that needs to be able to payout and lock the reel at any length for non-tension use for electrical current. Whatever the application, Duro cord reels are right for the job.
