Mechanical

Worm Gear 20 inch diameter able to hold post 90 tooth assists in position count. Will require a roller- thrust bearing for reduced friction loss.

Power required Total weight of 623 lbs EF of 2.5 Working weight of lbs Rgear = 21 in, RPM of dish = ½ Torque = WxR= x 21 in = lbin HP = TxRPM/63025 = x.5/63025 =.259 hp
