Product Description Andersen #72ST Self-Tailing 2 Speed Full Stainless Steel WinchFeatures: Aesthetically appealing A prerequisite for those yachtsman wanting their yacht to look i ts best. Full Stainless Steel - synthetic cap and bases are replaced with stainless steel partsPower RatioPower Ratio is the mechanical advantage of the winch and is calculated as follows:length of handle x gear ratio /radius of drumThe pull of the winch is based on the Power Ratio and not just on the physical size of the winch or the diameter of the drum. The Power Ratio is used to determine the load the winch may handle as follows: pull of handle (kg x Power Ratio = pull of winch (kg).This means that by applying a load of 10kg, using a 10" standard handle, on a Power Ratio 40:1 winch, the winch can pull 400kg, assuming that the winch is 100% efficient. This is not possible in practice as the efficiency is reduced by internal mechanical friction losses.Specifications Winch Model - #72 ST FS Drum Diameter "D" - 140 mm (5 1/2") Base Diameter "B" - 280 mm (11") Height "H" - 273 mm (10 3/4") Line entry height "L" - 120 mm (4 3/4") Line size - 10 - 18 mm (3/8" - 11/16") Weight - 24.5 kg (54 lbs) Gear Ratio 1st speed - 5.8 : 1 Gear Ratio 2nd speed - 20.3 : 1 Power Ratio 1st speed - 20.7 : 1 Power Ratio 2nd speed - 72.6 : 1 Service Kit 13 - Click Here for Service Kit Show more
