it could stress the frame. What I was short sidedly relating to is a situation I have in my own driveway. The drive way is level side to side, but not front to back as it naturally slopes a bit toward the street. The left side of my fiver is heavier than the right due to a couple of slides adding weight. With the axles sitting near level, the heavier side always slightly lags the lighter side when I unhook from my truck. The heavier side always slightly leads the lighter side when I lower it down back on the truck
it is a bit annoying. The cylinder never drifts after any use. I deal in hydraulics by trade
I have tried bleeding any air in the system, but the end result is as described above. Any time two cylinders are tied together with no flow control or balancing valve
if one has a lighter load
it will move a bit faster
thats the way things happen in hydraulics. Just to enable the capability to make the fiver sit level on near level ground I proposed adding the blocking valve
maybe I need to re-bleed my system yet again
. I never had this issue with the old electric jacks on my previous fivers
if it was level coming off the truck
both electric jacks pushed it up the same side to side.
You can get by with a balancing hose between the two cylinders to adjust for the delta P without the use of a flow control valve or balancing valve. Excavators and wheel loaders use this all of the time when two cylinders are controlled from two different spool valves and lifting/lower the same load.
Question for you since you have been into the hydraulic system on your trailer; are there load checks at the cylinders or in the lines?
