have made many gates. Now, I want to make one for myself. It will be
large, and long, and instead of making it on a sliding apparatus, I want to
anchor one bottom corner, and then use a hydraulic ram to raise and lower
it. The bottom corner would stay in its anchorage, and the gate would tilt
up 90 degrees to straight up. I have seen many of these lately, and they
use up a lot less space than the rolling contraption.
My questions have to do with the hydraulic system. How expensive/practical
would it be to make a pump and ram system where I could operate it in two
directions to lower and raise it? I have been looking at the Northern Tools
catalog, and they have everything I need. But, they are all over the map
pricewise. I want to get good stuff, and would not be adverse to buying
used components. I am just unsure of what I would need in the system.
Obviously, a bi-directional control, a long ram, hoses, etc. Would I need
any type of reservoir? I know there would be no need for a reserve in a
system that didn't leak, but am not sure how the hydraulic systems work.
Would I need limiter switches for when the gate was all the way up, or all
the way down?
What math would I use to calculate the size of ram I need? Or should I just
go with overkill, and get one that will travel farther and lift more than I
need? (my preference) Would I be able to put in manual overrides and a
hand pump in case the electricity goes out? (not common in my area) Or
just put a manual bleeder so I could just manually lower the gate in case of
I am also going to make a similar device to raise a section of patio roof so
I can park my motorhome, then drop the awning section back down once the MH
is past. But, I think I might use a manual jacking system on that rather
than running long runs of hoses, or putting in yet another pump system.
That is, unless there is a simple economical pump system available. I want
to use two rams on that one because of the length. Is it possible to put
two rams on one electrical pump or one hand pump?
Thanks in advance.
