Thread: Canopy power lift system

  1. #11
    had a couple of hours to kill before the grand kids get here so I took off to the salvage yard to see if they had anything new I could use.

    Found another power unit that was smaller than the ones I have so I pulled it.

    This unit operates just like the other ones.

    If it proves to be better than the ones I have I'll go back to the yard and pull the rest of the system.

    Interesting I never knew how those rear door closing mechanisms worked (chain driven). By the look of the size of the gearbox attached to the electric motor it gets a lot of mechanical advantage from the gears to give it lifting / pulling force

    this is the first version I have found that operates with a chain. All others have used gears.

    Not sure about the chain though. Looks like a problem waiting to happen if it breaks. But it is the smallest I've found that operates in a linear motion. The other versions that I've found use an arm that moves in a rotation motion so they need more room for the arm to clear things.

    Bottom one is the one that uses the arm that rotates.

    Each unit has enough lifting force to lift the canopy by itself but because the two lifting hinges of the canopy are not connected to each other two units will have to be used.

    They are neat looking contraptions. Other than stretch I don't think the chains would cause too may issues as long as they were lubricated & didn't get wet constantly.
