Starting and threading steel from a 5000 pound coil to a slitter can be very tough. Our customer had a stand with a hydraulic motor and mechanical clutch to feed the coil strip. Unfortunately, the starting shock regularly destroyed the clutch.
We reviewed the installation and found a limited existing envelope and very high starting torque capacity from the hydraulic motor.
We decided to use a flexible coupling with a known overload limit and an over-running clutch for the automatic disconnect required once the feed process is complete.
After some custom modification and mounting, this unique assembly was installed. Not only did it work, but the automatic feature simplified the whole operation.
