Guided Learning: Instructor will guide trainees through various rigging and hoisting calculations and reductions of hitches as well as demonstrate how force (weight) changes (is dynamic) Course Content Outline 1. Spring is a good time to review the standing rigging and make certain that it's prepared for a summer of sailing. Show changing forces as resultant moves. W Share of Load Weight Load Weight SLW Share of Load Weight R SRun RS Total Run (Span) L Sling Length H Height TS Tension in Sling CG Center of Gravity F Force CF Coefficient of friction – known runs: LW A = R2 x W RS : SLW B = R1 x W RS. You enter the lift weight and x,y,z co-ordinates for each connection relative to its CofG and Rigging will calculate the length and slope (vertical angle) of each leg in the assembly along with its expected. Know the load’s weight and the rolling equipment’s CoF (coefficient of friction). In the lifting and rigging industry, you want to make sure the angle is at least 30° or more. Then by considering the COG offset and based on the calculations at the second and third level, the number, size, and capacity of the rigging components selected for the preliminary design are optimized to ensure that the. 2) Select it from the search results.
