a lot of questions . I agree with the hydraulics sitting & not
working down the road .A couple of actuators with quick connect ball
fittings that ya can take off after use & keep in a warm place could be
a solution . Sang`s idea sounds like one that could be made to work
.. Can the lid have hinges on it so a guy/gal could slip a 3-4 `
bar into that could be used to open the hinged door ? More info could
probably get ya a home run .

something as simple as a long lifting lever that hooks the front of the lid
and lifts it just enough (a couple of inches) so it can roll back a
foot or two. Thanks for that idea! The implement could be kept in the
shed when not in use. I need to think about this approach. Actually,
just a better handle on the front of the lid might help a lot. That`d
be an easy welding project.

brake systems typically fail if the car is rarely driven, like the 1955
Ferrari kept under a tarp in the barn? (Jay Leno`s barn, not mine!)

there`s no shop air at my lake cabin. Ah, but there is water pressure
from the well pump! Perhaps I could devise an air over water device
that could be drained after each use (so no need to winterize) and use
the well pump as prime mover. I think the system pressure is about 40
PSIG, so an actuator producing 15 lbf of force (66.7 Newtons for y`all
thoroughly modern mechhies) ( one of four such) would need a piston or
bellows area of 0.375 in^2 which would be a diameter of 0.691 in, just a
bit under 3/4". So go with 1" dia and let the SOB leak air, or water
for that matter, there`s plenty of both. Now we`re getting to hydraulics
where greased pump leathers from old bicycle pumps would suffice.
I`ve seen lots of folks with those " dog houses " over their
wells. On the smaller ones like the one you have they hinged the roof so
they could tip it up & then use a rod that pivots on both sides to
lock the roof from falling when open .
