Linear Actuators

[PILOON]

FYI, they used linear actuators on the early satellite dishes (those big 8ft dishes) to align with the different satellites.
Most had about 20" travel but worked on 24 VDC. They'll also do fine on 12VDC, just slower.

I had a 12v actuator opening and closing my chicken house door at dawn and dusk. I used an old car power antenna relay to reverse its direction. The actuator had built in limit switches. Give the antenna relay 12 volts and it would reverse the direction of the actuator. I think I paid $5 for the relay at a junkyard.

From what I have seen most all the linear actuator attact with a 6mm or 1/4" bolt. Does that hold up to the force of the snow pounding on it? That seems small.

I got mine from here:https://www.firgelliauto.com/
They have switches and brackets also.

The JD remote spout control also attaches with a 6mm bolt (19M6755) and there have been no reports of it being a problem.

Lol, have the same thing. 12" actuator on a DPDT switch hooked to an old 12v laptop power supply. It runs a small side door. The wife got a [http://coopboss.com[URL] for her b...lock as you drive off with the new implement.

I wrote a thread and enclosed a few pictures regarding installing a linear actuator to do exactly what you have in mind. You might want to check it out:
