Sling Length Selection Calculator – Rev 0 is a one-page interactive PDF tool designed to help users select an effective sling length range before checking sling angle and MAR/WLL requirements.
This tool is useful when planning or adjusting a lift setup and asking:
Given my vertical rise and spread, what effective sling length range should I use?
What’s Included
- Sling Length Selection Calculator – Rev 0 PDF
- ReadMe / License / Disclaimer – Rev 0
What It Calculates
The calculator provides:
- Offset used
- Target effective sling length
- Length at standard angle
- Maximum length at minimum angle
- Effective length selection range
- Simple geometry status
It supports:
- Two-leg symmetric lifts
- Single-side offset geometry
Inputs and outputs use a practical feet/inches format.
Sling Angle Geometry Calculator – Rev 0 is a one-page interactive PDF tool designed to help riggers, supervisors, and lift planners calculate the sling angle relative to the horizontal using simple field measurements.
This tool is useful when sling lengths are changed, connection points are adjusted, or the crew needs to verify the actual sling angle before checking rigging component requirements.

Calculation Methods Included
The calculator includes three common geometry methods:
Method A – Vertical Rise + Horizontal Offset
Use when the rise and offset are measurable in the field.
Method B – Sling Length + Vertical Rise
Use when the effective sling length and vertical rise are known.
Method C – Sling Length + Horizontal Offset
Use when the effective sling length and horizontal offset are known.
Each method outputs the sling angle from horizontal to two decimal places and provides a green/yellow/red status based on the standard and minimum angle settings.

Rigging MAR Field Calculator – Rev 0 is a one-page interactive PDF tool designed to help field crews and lift planners calculate required minimum allowable rating / WLL values for common below-the-hook rigging components.
The calculator uses entered lift data such as load weight, number of sling legs, sling angle, hitch type, dynamic factor, utilization factors, and selected component WLL values to produce required MAR outputs and pass/fail status messages.
This tool is intended to support field planning and verification conversations before a lift.
Rigging Field Calculator Suite – Rev 0 is a three-tool interactive PDF calculator package built for field crews, riggers, lift planners, supervisors, trainers, and industrial maintenance teams who need quick, practical rigging calculation support without opening a full spreadsheet.
This suite is designed to help users work through three common field questions:
What effective sling length should I select?
What is my actual sling angle from horizontal?
Do my selected rigging components meet the required MAR/WLL?
The tools are built as clean, one-page interactive PDFs. Enter the field measurements, click calculate, and review the output fields and green/yellow/red status messages.
