3. Duty Cycle: Influenced by load, speed, and temperature.
4. Self-Locking Jacks: Require power to raise or lower.
5. Brake Motor Requirement: Necessary for certain jacks.
6. Travel Speed Limitations: Varies by jack type.
7. Maximum Screw Length: Limited by column load.
8. Calculated Life for Screws: No formula for machine screws.
9. Screw Stops: Offered as options.
10. Hard Stops: Not designed for operation into hard stops.
11. Operating Temperature: Standard range is 40°F – 220°F.
12. Lubrication: Specific grease and oil requirements.
13. Horizontal Mounting: Recommendations for mounting position.
14. High Screw RPM and Long Lengths: Additional support required.

Column Load and Mounting Configurations
1. Load Types: Tension and compression affect capacity.
2. Mounting Types: Includes unguided, trunnion, guided, and double-clevis.
3. Using Column Loading Charts: Steps to determine appropriate jack.

Jack Designs
1. Translating Design Jacks: Driven worm acts on wormgear.
2. Keyed Design Jacks: Prevents lifting screw rotation.
3. Keyed for Traveling Nut Jacks: Lifting screw rotates but does not translate.

Torque and Horsepower Calculations
1. Example Calculations: Provided for calculating horsepower.
2. Considerations: Account for inefficiencies in miter boxes and gear reducers.

Horsepower Requirements
