Sling Inspection, Load Factors & Rigging Formulas Made Easy
Professional Pocket Reference for Riggers, Crane Operators & Safety Personnel
Boost job site safety, accuracy, and efficiency with the Rigger Reference Card, your all‑in‑one laminated field guide for rigging and lifting operations. Designed to meet OSHA and ASME B30.9 standards, this card provides vital information on sling inspection criteria, load control hitches, hand signals, and critical rigging formulas — all in one durable, pocket‑size reference.
Key Features & Technical Factors
- ASME B30.9 Sling Inspection Criteria
Covers removal and inspection standards for wire rope slings, web slings, polyester round slings, and alloy steel chain slings. Helps ensure compliance with OSHA and ASME safety requirements by making it easy to spot wear, corrosion, or damage before lifting. - Load Control Hitch Reference (LC Ratings)
Features detailed illustrations for vertical, choker, basket, and multi leg bridle hitches. Each diagram includes a load control rating (LC = Poor, Average, Good, or Excellent) for quick, visual guidance on the safest lifting configuration. - Crane Hand Signals (OSHA Standard)
Includes all hand signals for safe crane operation — from hoisting, lowering, and traveling to emergency stops and boom extension. Clear illustrations make communication between riggers and operators fast and accurate. - Factors and Formulas for Rigging & Sling Angles
Provides a handy Sling Tension Formula to help riggers estimate how much force is carried by each sling leg during an angled lift.
The sling tension formula is used in construction rigging to estimate how much force (tension) is carried by each sling leg when a load is lifted at an angle. As the sling angle gets smaller (the slings get more horizontal), the tension in the slings increases.This section makes it easy to perform quick calculations or verify load safety factors right in the field. - Durable, Weather Resistant Construction
Made from laminated, heavy duty material that resists moisture, grease, and tearing. Perfect for harsh job sites and long term use. - Portable & Field Ready
Compact pocket size fits into your gear bag, safety vest, or toolbox — an essential daily reference for riggers and crane operators.
Perfect For:
- Riggers and signal persons
- Crane and hoist operators
- Construction foremen and lift planners
- Safety inspectors and supervisors
- Anyone who needs quick access to rigging reference data
Why Choose This Card
Ensure compliance, prevent overloading, and improve lifting accuracy with the Rigger Reference Card. By putting critical rigging formulas, safety standards, and OSHA hand signals in one convenient tool, you’ll save time, avoid mistakes, and make every lift a safer one.
