And they are cheaper than buying a general purpose actuator. I believe they use reed switches to allow their controllers to "count" angles between satellite positions, but these can be ignored. Most satellite movers have a convenient movable clamping arrangement as well.

What about using a 36 volt satellite arm dish mover. They are quite strong (1000 lbs) and made to be used outdoor. They have up to 36 in of stroke. I got one that I want to use on a small dumping trailer for my E-20.

I use a few "linear actuators" - the electrical version of a hydraulic
cylinder. Mine are 12 volt, but I bet there are some 36 volt versions out
there. This would be quite different than the strap lift in that it would
be positive down pressure and position holding rather than the lift only
(and float) strap arrangement, so it might not be useful with all
implements. But it would make a cool dozer. I use one rated at 400 pounds
on a ski trail groomer, and it has been exposed to snow and ice as well as
punishing loads for several years with no problem. It would be ridiculously
easy to install one in place of the lift..

================================
I have a New Idea big frame tractor, and the lift motor is entirely
different than any I have seen on the GE tractors. It appears to me to be a
much
heavier motor, and has a different gear box arrangement. It is definitely
NOT a window lift motor from a GM car. I have posted several photos on my
Kodak photo site at: http://goo.gl/NIAzs
When I attached one of these lifts to a GE front bumper I had to redrill
the holes in the bumper.
I did see on this forum that some New Idea lift motors were rated for 36
volts, and these were suppposed to have an orange dot on the motor, as I
recall. I couldn't see any orange dot on the two NI motors that I have so I
stayed with 18 volts.
I have previously suggested using a motor and gear box that are made for
moving slide rooms in RV's. If you have an RV salvage store in your area I
would suggest looking there. I am in the heart of the RV industry in
northern Indiana, and we have several of these stores, with a big selection
of
slide room motors. I have several of these in my "stuff". One of them is
way
too slow, but another one appears to be about right, although I have had no
need to adapt this to my New Idea, so I don't know whether it would work.
