how to lift vertically with gas assist cylynders?
we have an overhead canopy that need to be lifted 3 feet into the air, and then let down to its origianal position at the end of the day. it now goe's up and down with a smaller tube within a larger tube and pins put in position to hold it at the right height. the size of the canopy is 4' x 12' and weighs approximately 150 lbs, as the supports are made from aluminum. As we are not getting any younger it is taking its toll putting it up and down manually. If there any way that we could re
place the smaller inner tube with some type of gas assist cylynder that would take it up and down mechanically? Imagine having to lift a box .,and then down again straight up and down. Any replies would be appreciated. Thank you. JOJO
