SWL = Ultimate (Breaking) Strength/Design (Safety) Factor Usually the safety factor used in lifting equipment is 5:1. Example: If you are using a 0.5" Improved Plow Wire Rope the ultimate strength is 11.5 tons. SWL = 11.5/5 = 2.3 tons The safety factor should go higher if there is possibility of injury or death. Example: Elevators use a 20:1 safety factor.

What is the formula for calculating the bollard pull and HP?
Bollard pull is typically calculated using the formula: ( BP = \frac{(T \times V)}{33000} ), where ( BP ) is the bollard pull in pounds, ( T ) is the thrust in pounds, and ( V ) is the speed in knots. To convert bollard pull to horsepower (HP), you can use the formula: ( HP = \frac{BP \times V}{550} ), where ( V ) is in feet per minute. Thus, bollard pull and horsepower can be connected through their relationship with thrust and speed.
