[QUOTE="Yellowyj, post: 692331, member: 3504"] Maybe a little late but was studying this gate opener today on one of my job sites, basically the chain is attached to either end of the gate and runs thru the box where the motor drives the chain in and out. I haven't opened up the box to see how the gears and motor are set up, but will try to open it up later this week to see exactly how the chain is driven by the gears/motor. I thought of this thread while I was standing there looking at it. I saw a similar chain driven assembly on an old sliding fire door in the back of an old Kmart we are tearing down several weeks ago and forgot to take a picture of it. The motor and gear box looked similar to this gate opener, but was a smaller chain like on a residential garage door opener. It was mounted on the floor and pulled the door open so the door was between the the opener and the wall when open. Our demo sub was salvaging both the sliding fire doors that were like that.
