) to ensure the steel beam will not yield or deflect beyond allowable limits:

These factors are used to calculate the actual load on each leg of the sling: Tension = (Load / Number of Legs) × Angle Factor .

Standard onshore lifts typically utilize a DAF between 1.10 and 1.30 depending on the crane type and speed. Wind Loading on Heavy Lifts

ratio is less than 25, you must apply a reduction factor to the sling's Rated Capacity according to industry standards (such as ASME B30.9). 3. Advanced Lift Planning Factors DAF (Dynamic Amplification Factor) ) to ensure the steel beam will not

When a load is asymmetrical, the weight is not shared equally among the lifting points. To find how much weight each point carries, use the principle of levers (moments).

To design a safe lifting plan, engineers and rigging supervisors use specific mathematical formulas to calculate sling tension, crane capacity requirements, and hardware ratings. Sling Tension Calculations

Rigging Engineering Calculations: A Practical Guide (ITI) To design a safe lifting plan, engineers and

Practical examples demonstrating how to use formulas.

A rigging engineer’s primary task is to quantify the forces involved in a lift to select appropriate hardware and crane configurations.

The most basic, yet most critical, calculation in rigging is determining the actual tension applied to individual slings. When slings are used at an angle, the tension increases dramatically due to the introduction of horizontal forces. The Sling Angle Factor (SAF) The most basic
