PLANNING RESOURCES
Tools for the planning conversation.
Use the existing calculators to explore inputs, then bring your application and results to engineering for review.
JOBSITE CALCULATORS
Choose your planning tool.
Planning reference only. Validate inputs, results and the complete equipment configuration with engineering before use. Review the calculator’s existing notices and instructions.
Job Site Calculators
Choose a calculator below. You can print results from inside each tool.
Platform Capacity Calculator
Values use Sky Climber tables (UL1322) and Work Cage catalog data. Print-ready summary included.

Important: Distribute loads. Use only listed configurations. Final setup must be reviewed by a qualified person per OSHA/ANSI and Sky Climber manuals.
Counterweight Calculator
For topside outrigger beams. OSHA safety factors. Calculates required CW per beam (stirrup) and shows fulcrum working load for mounting on dollies or scaffold frames.

Important: Keep the outreach-to-backspan ratio ≥ 1.5 : 1. When using 1500 lb hoists, outreach must not exceed 3.5 ft on a standard beam and 5 ft with a cable truss. Follow the manufacturer’s manual or approved drawings and use under the supervision of a competent person.
Voltage Drop Calculator
Estimate running voltage at the platform. Assumes SOOW (stranded copper) cords. For planning only—verify on site.
Results
*1-phase uses 2 × I × R × L. 3-phase uses √3 × I × R × L. R is SOOW stranded copper resistance per foot for the selected AWG (≈20 °C). Actual drop may be higher due to warm cords, connections, or older cables.
