Solution
Ametek installed a 2006 Rotary Cam Limit Switch off of the cable drum to monitor the hoist travel and set the lower and upper limits to avoid overtravel.

- Safety
- Prevents damage to motor and drive mechanism
Conclusion
A simple mechanical Rotary Cam Limit Switch can save hundreds or thousands of dollars and avoid hours of downtime caused by overtravel.
