Combines Power Fold ladder question for SD 455

what ever you do make sure you have a RESTRICTOR or shut off valve to use as a restrictor. That little reel lift ram will launch a space shuttle or a real man into orbit if he happens to be standing on the ladder or next to it. Most of the ones I have seen use a spring to pull it down over center. Works neat - just need to figure out the linkage.

I set my linkage such that the ladder would go down by gravity. The ladder never went over center towards the cab. Just hold the lever down and the weight of the ladder would do the work. I used a fitting with a 1_8" thru hole to restrict the flow.

I fastened a 12v winch to bin to pull ladder up .Cheap and works good.

The cylinder I used was a 1 1_2" X 9" cylinder I got from the Surplus Center. It had a clevis mount on each end with 5_8" holes.
