**How did you find PF?:**looking for simple formula to calculate force needed to raise steel tower. I am not on social media and have no idea how to use a forum.

at almost 80, I find having to hand crank a ham radio tower up and down to be challenging. I must lay it down to work on the antennas. (It is a self supporting, 4 section steel tower that hand cranks up and down.) To lay it down, one must un-crank until it is horizontal. It has 1/4" steel cable and if I "pluck" the cable, it has a tone somewhere above middle C. Very tight. I would like to convert to a winch but have no idea as to the strength needed to raise and lower the tower.

It is 21' long (tall), weighs between 1040 and 1200 lbs. One of your commentators said that if you pick up one end, you are lifting 1/2 the weight. The tower is hinged at the bottom and has a pulley at 7' above the ground. The cable comes from the hand crank over a pulley. to the tower pulley and back to the top of the pulley post and hooks with a hook. (if I am correct, one doubling strength)

Common sense is telling me that if lifting from the top is 1/2 the weight, the closer one gets to the bottom of the tower, the more force is needed to move the tower. (I am also guessing it is a log progression.)

Is there a formula or can someone help me out. Thanks.
