Guidelines for determining overhead required:
For 3 Stage Jack
- Car Speed = Up to 150 FPM
- Top Overtravel = 12″
- Bottom Overtravel = 8″
- Pit Depth = 4′ -0″
- Cab Height = 8′ -0″
3 Stage Jack Overhead Requirement:
Minimum of 12′ -8″ overhead required for 30′ -6″ of travel and under. Add 11/32” to 12′ -8″ for every additional 1″ of travel over 30′ -6″.
