A web-based planning tool that helps competent riggers generate rigging force calculations for a variety of configurations, particularly in the communications tower industry.

You won’t find a pirated SC&RA manual here, but these sources offer authoritative, no-cost materials:

Instructions on how to read boom length vs. radius. A web-based planning tool that helps competent riggers

Here are a few options to consider:

Fc=Vertical Load on One Side×tan(ϕ)cap F sub c equals Vertical Load on One Side cross tangent open paren phi close paren (Where is the angle between the sling and the vertical line). 3. Crane Rated Capacity and Deductions Here are a few options to consider: Fc=Vertical

Evaluating ground bearing pressure to ensure the crane mats and soil can support the combined weight of the crane and the load. Safe and Approved Rigging Engineering Resources

Gross Load=Net Load Weight+Hook Block Weight+Rigging Hardware Weight+Hoist Rope WeightGross Load equals Net Load Weight plus Hook Block Weight plus Rigging Hardware Weight plus Hoist Rope Weight Deductions Checklist When calculating net capacity, always deduct: Main hook block and headache ball. All slings, shackles, spreader bars, and equalizer beams. The weight of the wire rope hanging below the boom tip. Jib stowed or erected on the boom. 4. Ground Bearing Pressure (GBP) calculations but these sources offer authoritative

The tension on a sling increases drastically as the horizontal sling angle decreases. When lifting a load with multiple legs, engineers use the sling angle factor (SAF) to determine the actual force exerted on each sling:

Ensure your calculated GBP is strictly lower than the verified soil bearing capacity of the job site. 5. D/d Ratios and Sling Efficiency
