What equation is used to calculate distance from point A to the edge sheave on a LWFB?

The equation used to calculate the distance from point A to the edge sheave on a Light Weight Fixed Boom (LWFB) is integral for ensuring accuracy in low-profile crane systems. The correct choice utilizes the pendant length, a critical measurement indicating the length of the supportive cables, combined with a fixed value that represents a standard adjustment for positioning with respect to the sheave.

In this case, the calculation adds 15 divided by 2 to the pendant length. This specific value reflects a well-established method within the industry that accounts for both the vertical and lateral dimensions necessary for proper drone or crane operation. It creates an effective distance that encompasses safety margins, mechanical allowances, and operational range, which are crucial for effective lifting operations.

The other potential options differ in their adjustments, reflecting slight variations in presumed operational requirements or theoretical applications, which might not align as closely with the established standard used in practice for this type of equipment. The choice that includes 15 as a critical component aligns with common industry metrics, enhancing operational safety and efficiency when determining the distance to the edge sheave.
