Re: Confusing Video
Our 2005 arm was aided back down by gravity and because of that it proved painfully slow. It was 9ft. high and took about 4-5 seconds either way. This one is 8.5 feet high and it goes up or down in less than two second regardless of its aid by gravity. We didn't want gravity to be the driving force for lowering the tower and we came up with the mechanism you see to power the tower both up and down efficiently and quickly.
