What specific are you planning (e.g., tandem crane lift, basic mobile crane lift)?

Rigging engineering requires a deep understanding of physics, material science, and structural engineering. Accurate calculations ensure that every component of a lifting system operates well within its safe working limits. 1. Tension and Sling Angles

Rigging engineering is a specialized branch of mechanical and civil engineering focused on the planning and execution of lifting, moving, and securing heavy loads. Unlike general construction, it requires precise mathematical modeling to ensure that equipment—such as cranes, slings, shackles, and spreaders—can handle the dynamic forces involved without failure.

When slings are used at an angle, the tension in each leg increases. The formula is weight, is the number of legs, and

Spreader bars are highly efficient, lightweight, and ideal for wide loads, but they require significant headroom. Lifting Beams (Bending Forces)

What specific are you planning? (e.g., tandem crane lift, modular spreader bar design, off-center CG) modular spreader bar design

Every lift plan begins with calculating the actual tension applied to the slings. When slings are used at an angle, the tension increases significantly due to horizontal forces. The Sling Angle Factor (SAF)

If the hook isn't directly over the CG, the load will shift or "swing" the moment it leaves the ground. 2. Sling Tension and Angles
