Vertical Lift Gate Folds Out Of Way
Jack Kaspari wanted a gate that wouldn't get hung up in the snow, so instead of a swinging or sliding gate, he built one that raises up vertically. The 12-ft. long gate can be raised and lowered with a switch at the gate or from a transmitter in his car or even from his house 250 ft. away. The gate works smoothly, but it took some effort to work out the details.
"I had to make a model of it to get the cross bars and the channel iron uprights just right," recalls Kaspari. "Each of the four cross bars had to be offset a little before I pinned them in place so they would fold up on themselves."
The gate itself was the easy part once he got the design right. It consists of two 4-ft. upright 1 1/2-in. channel irons with one secured to the gate post. The second upright swings free as it rises into the air and folds. The 12-ft. cross bars are 1-in.square tube stock.
"If I was doing it over, I would use 1 1/2-in. tubing and add a couple more feet to the length," he says. "That would make it more solid. As it is, it vibrates a bit when I drop it down."
The lift mechanism is an electric winch mounted at the base of the post to which the gate folds. Kaspari used an old power pole for a gate post, giving him the height he needed. The cable runs from the winch to a pulley mounted at the top of the post. From there it runs out to the top corner at the far end of the gate.
The winch is controlled by a 12-volt, three channel receiver powered with a 120 to 12-volt converter that Kaspari picked up at Radio Shack. Since the receiver had a one amp maximum, he installed three relays, one for up, one for down and one for a yard light installed at the top of the pole.
If someone comes to the gate after dark, Kaspari can turn on the light before deciding to open up. Best of all, he doesn't have to worry about snow drifting against the gate.
"It beats trying to swing a gate or even lifting it," he says.
