Wire Rig Safety Engineering & Design Analysis
Analyze wire rig designs, calculate safety factors, and generate compliance documentation
What You Can Do
You can submit wire rig designs, equipment specifications, and stunt parameters to receive detailed safety engineering analysis. Claude calculates actual vs. rated load capacities across multi-point rigging systems, identifies potential failure modes, flags compliance gaps, and generates formal safety reports ready for insurance and film commissions. This transforms conceptual designs into verified safety assessments before rigging setup begins.
Features
Compute safety factors across cable, shackles, motors, and attachment points with industry-standard engineering margins
Evaluate complex anchor systems, suspension angles, and force distribution across multiple support structures
Flag weak links, stress concentrations, and edge cases that could compromise system integrity
Assess cable ratings, hardware certifications, motor specifications, and control system redundancy
Generate formal safety reports, risk matrices, and mitigation plans aligned with OSHA, SAG-AFTRA, and local film commission requirements
Evaluate multiple rigging options side-by-side on safety, feasibility, and cost factors
Analyze equipment concerns and near-misses to determine root causes and preventive measures
Identify missing procedures, testing requirements, or contingency plans in existing rigging protocols
Example Output
Example 1: Cable Load Analysis
Input: 200 lb performer, 3-point aerial suspension with 3/8" aircraft cable, 45° angle rigging
Output:
- Rated cable capacity: 5,400 lbs (working load limit)
- Actual distributed load per cable: 77 lbs (at 45° angles)
- Applied safety factor: 70:1
- Assessment: ✓ EXCEEDS minimum 8:1 safety factor. Acceptable configuration.
- Hardware cross-check: Shackle rating 4,500 lbs verified adequate.
Example 2: Risk Matrix
| Risk | Probability | Impact | Mitigation |
|---|---|---|---|
| Cable abrasion at roof edge | Medium | Catastrophic | Add edge guards, inspect cable every 10 takes |
| Motor control system failure | Low | Severe | Dual-circuit backup motor, manual descent capability |
| Rigging assistant error | Medium | Severe | Checklist protocol, certification requirement |
Example 3: Compliance Gap Report
Missing items for SAG-AFTRA submission:
- ☐ Third-party structural engineer sign-off for building attachment points
- ☐ Load testing documentation for cable/hardware assembly
- ☐ Emergency descent procedure with timing specifications
- ☐ Rehearsal protocol with performer in full costume/makeup
Recommended: Complete items before talent call.
