Field Factors And Hitch Capacities Flashcards
What is the field factor for a pick with two slings at 90 degrees
Svc x 2
If you were using svc x 1 what angle would your slings be at
30-44 degrees
What would the field factor for slings between 60-89 degrees be
Svc x 1.7
What is the field factor if your slings are between 45-59 degrees
Svc x 1.4
If your load is choked does it change the formula to estimate your hitch capacity using field factor ?
Yes
Choke value x field factor
If you have a bridle basket what is the formula to estimate hitch capacity using field factors
Svc x field factor x field factor
What is the formula for a single vertical hitch
Hitch capacity = SVC
What is the hitch capacity formula for a true basket or bridle with vertical legs
HC = SVC x 2
What is the formula for the hitch capacity of an inclined leg basket or a bridle with inclined legs
HC = SVC X 2 X H/L
What is he formula for a hitch capacity of a bridle basket
HC = SVC X 2 X H/L X 2 X H/L
What is the formula to determine the hitch capacity of a bridle choke more than 45 degrees
HC = SVC x .75 x 2 x H/L
What is the formula to determine the hitch capacity of a bridle choke less than 45 degrees
HC = SVC X A/B x 2 x H/L
What is the formula to determine hitch capacity of a single choke more than 45 degrees
HC = SVC X .75
What is the formula to determine the hitch capacity of a single choke less than 45 degrees
HC = SVC x A/B
