Gross Load Breakdown
Preset Lift Logic by Lift Type
ANSI 10.48 Class Rigging Guidance
Class II
- Prepared by a Competent Rigger or a Qualified Person with onsite competent person involvement.
- Handline hoisting under 35 lbs does not need documentation.
- Qualifying lifts with gross loads not exceeding 500 lbs when no Class IV trigger is present.
Class III
- Prepared by a Qualified Person with onsite involvement of the Competent Person(s).
- Normal construction methods not affecting structural integrity.
- Qualifying gross loads above 500 lbs and not exceeding 2000 lbs.
Class IV
- Prepared by a Qualified Person with onsite competent person involvement and a Qualified Engineer.
- Gross loads exceed 2000 lbs, special methods, demolition, instability, or high-concern anchors.
- Straight tag lifts with load-position angles over 10° from vertical and/or tag angles over 70° from horizontal require additional review regardless of load.
Select a Supported Lift Calculation
Dedicated dual-trolley module: The Teasley arrangement uses TWO separate travelling pulleys — a TAG-LINE TROLLEY on the control/tag line and a LOAD-LINE TROLLEY on the lifting line. Replay keeps these rope paths separate so students can see how both trolley systems interact without falsely combining them.
Validation status: Unit-Aware Physics Loaded — US/Metric equivalency check active; benchmark verification still required before final Math/Physics Verified status. US input treats Gross Load as lb-force; Metric input treats Gross Load as kg mass and converts it to weight before the same Teasley vector equations run.
Dedicated TSRE geometry model: Only the Lift #7 inputs shown in this panel are used for the 2:1 geometry and force solution. Generic lift-geometry fields are hidden to prevent duplicate or conflicting inputs.
This module uses the same physics model as the Tower Safety 2:1 simulator. Keep the top and heel pulleys close together on the approved attachment location. Tower-leg distance changes the analysis triangle; it does not spread the top and heel pulleys apart.
Dedicated TSRE geometry model: Only the Lift #9 inputs shown in this panel are used for the 3:1 geometry and force solution. Generic lift-geometry fields are hidden to prevent duplicate or conflicting inputs.
Rope path: knot at load → Top Pulley #1 → travelling pulley → Top Pulley #2 → heel pulley → capstan. Three directed rope parts support the load. The engine resolves their actual X/Y directions rather than assuming the load is simply divided by three.
Optional Tag-Line Geometry
Angle alone does not determine tag-line force. Enter the expected or measured tension. The tag line is treated as an external load-control force, not mechanical advantage.
Gross Load is entered on Overview. Dynamic Load Factor and Wind Speed remain visible above.

Engineering Validation & Assumptions
Engineering basis. The Tower Safety Rigging Platform assists with planning, review, education, and documentation using classical mechanics, vector resolution, static equilibrium, pulley reactions, mechanical advantage, geometry, dynamic load factors, selected efficiency or loss assumptions, and equipment-utilization comparisons.
Calculation assumptions
- Flexible rope and quasi-static equilibrium unless a dynamic load factor is applied.
- Selected system-loss values represent the lift module's stated efficiency model.
- User-entered geometry represents the planned field configuration.
- User-entered equipment ratings and hitch-specific WLL values are accurate, current, and applicable.
- Rigging equipment has been inspected and is suitable for service.
- Wind, weather, and site conditions are independently evaluated.
Platform evaluates
- Rope tensions and mechanical advantage
- Pulley reactions, vectors, and resultants
- Geometry effects and selected dynamic factors
- Equipment and attachment utilization from entered ratings
- Teaching and review thresholds
- Plan documentation and lift-class review prompts
Outside calculation scope
- Tower and foundation structural capacity
- Soil capacity and temporary-guy engineering
- Gin-pole structural engineering
- Crane manufacturer load-chart verification
- Anchor structural adequacy not established by entered verified capacity
- Manufacturer-specific instructions and hazards not entered into the platform
Validation status
Lift #7 and Lift #9 use dedicated TSRE adapters. Other lift modules retain their current calculation logic or require Qualified Person values where a dedicated adapter is not available.
Platform: Production Edition v2.2.16
TSRE: Core v1.0
Attorney review: Pending
Professional Use & Limitations
Planning and educational aid. This platform is intended to assist trained personnel with planning, review, visualization, education, and documentation of rigging operations. It does not replace the judgment, duties, site-specific evaluation, or required involvement of a Qualified Person, Competent Person, Qualified Engineer, crane professional, employer, or other responsible party.
User-entered information. Results depend on the accuracy, completeness, units, and applicability of the information entered. Users must independently verify geometry, loads, dynamic factors, equipment condition, manufacturer ratings, hitch configurations, anchors, attachment locations, hoists, capstans, environmental conditions, and all output values before work begins.
ANSI/TIA-10.48 support. The platform is designed to support planning concepts associated with ANSI/TIA-10.48 where applicable. Use of the platform alone does not establish compliance with a standard, regulation, contract requirement, manufacturer instruction, engineered design, or site-specific lift plan.
Structural and site evaluation. Unless separately documented by qualified professionals, the platform does not determine the structural adequacy of towers, foundations, anchors, gin poles, temporary guys, soils, cranes, or other supporting systems. Conditions may change after a plan is generated and must be reassessed before and during the lift.
Required verification. The person or organization planning and conducting the lift remains responsible for reviewing calculations, resolving warnings, confirming equipment capacities, completing required inspections, following manufacturer instructions, applying applicable standards and regulations, and stopping work when conditions are not as planned.
Interim language pending attorney review. This section is a professional-use statement and limitation of scope, not legal advice and not a guarantee that risk or liability is eliminated. Tower Safety intends to have the final language reviewed by qualified counsel.
Professional Use, Verification & Limitation of Liability
The Tower Safety Rigging Lab users are solely responsible for independently verifying every aspect of the construction plan, calculation, equipment selection, structural capacity, site conditions, manufacturer instructions, and all applicable codes, standards, and regulations before performing any lift or related work.
This platform does not constitute engineering advice or a structural analysis. Hazards, conditions, and forces not expressly evaluated by the user remain outside the scope of this tool.
Tower Safety, its owners, and affiliates make no warranties, express or implied, regarding the accuracy, completeness, or suitability of any information or results generated. In no event shall Tower Safety be liable for any direct, indirect, incidental, or consequential damages arising from the use of, or reliance upon, this platform.
Use of this tool is restricted to trained and Competent/Qualified Riggers according to the ANSI 10.48-2023 who accept full responsibility for all decisions and actions.
