Thanks. The problem with hydraulics is that they need a control and perhaps
an energy source accessible from outside where they invite tampering. Even a
recessed Schraeder valve to pressurize roller-raising air cylinders with a
bicycle pump or CO2 tire inflater could become uncapped and filled with dirt
by wind or wasps. Can you accept an external opening device that could break
or be lost or forgotten?
-----------------------------
Another afterthought: The compressed air outlet beside my garage door is a
water faucet with a DIY screened cap to keep mud wasps out but not lock in
place if pressurized. It looks normal on the garage, wouldn`t seem out of
place on a well house and takes compressed air fittings with an NPT to GHT
adapter. Removing the knob should make it less tempting to tamper with. The
valve could lower the lid gently after removing the pressure source.
