- Center of Gravity – effects on suspended load.
- Headroom – calculating sling length using Pythagorean Theory.
- Taglines – basic do’s and don’ts.
- Hitch Types – vertical, choker & basket.
- Load angle factors – calculating force on a sling based on the angle.
- D/d ratios – resultant decrease in a slings ultimate strength.
- Load Weight Estimation – for common construction materials.
- Sling Protectors – 3-types including cut protection for synthetic slings.
- Crane Signals.
