Rigging engineering calculations are critical to ensure the safety and effectiveness of rigging operations. By understanding the calculations involved and accessing PDF resources, individuals can perform rigging engineering calculations with confidence. The PDF resources mentioned in this article can be downloaded for free and provide valuable guidance on rigging engineering calculations.

The strength of a wire rope is compromised when it is bent over a sheave or a pin. This is measured by the (Diameter of the bend / Diameter of the rope).

F = m x g / (2 x cos(θ))
