Linear Actuators

[reddog6601]

I would like some advice. I want to put a 12 volt linear actuator on my snowblower shoot deflector. It looks like a minimum distance of 22" and a maximum distance of 30". There is a 12 volt outlet next to the back window. I would like to plug in there and have a rocker switch for the in and out (or up and down) function. Can someone stear in it the right direction? Thanks

The min / max indicates you need 8" of movement. The LA can be lengthened using a solid extension. It may be easier and less expensive to find an actuator with the range you need and then modify the mounting to make it work. I found mine on line and it has built-in limit switches to prevent it from being damaged when it reaches its limits. Simple matter of reversing polarity to reverse the travel. I built a relay box for the rotation and up/down of the chute. Two small rocker switches are on a pendant in the cab and the blower wiring connects to the cab via a trailer type connector.

http://www.progressiveautomations.com is a good quality source. I've got several no name actuators that look similar to theirs for various things & one of their 500-600lbs rated ones for my power SSQA. They all come with the required built in limit switches.

Just apply +12v & ground, they extend. Reverse the polarity & they retract. A quick Google of "DPDT wiring a linear actuator" should show you pictures of how to wire up a standard $5 double throw double pole switch to run one. I never bothered with relays for the cheap light ones that pull under 5@.

Chim, where did you get that motor running your rotation pully?

Here is how I have been doing motor reverse on my linear actuators. Allows you to use small switch with small wires and mounts switch where ever you want. Depending on your application you can mount things in different places. I have post on here with more specifics on how I did it.

Here:

CAR SEAT 3-12VDC GEAR MOTOR

I did some moification to the shaft of the motor and to the snowblower crank as well. It works fine.

Thanks. I've got the winch from the plow I've been thinking of using. But at 2,500lbs rated I'm guessing, its WAY overkill for this use & could easily break things, not to mention require lots of heavy wiring.

The speed on that motor about right? I'm guessing its not rated waterproof, but as long as its not to bad at that price you can afford to replace it every few years.

I got my water proof one here

here is post on how and why I did it the way I did.

Was asking about waterproof in relation to the rotary as opposed to linear actuator. There are a ton of clones out there for that basis 5@ 200lbs ish design. Most are pretty weather resistant & have decent IPS ratings.

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:
