I am confused on "my jacks has collapsed on itself". I think you are saying it released the pressure and did not support the TC during storage. I do not think hydraulic jacks are designed to support a TC during storage. You should put supports under the TC for storage. Personally, I would never use a TC supported by the jacks only. I would not consider storing my TC for even a couple of hours on hydraulic jacks only. I trust them only while I'm looking at them.
One of the photos suggest at least one jack is not properly installed. They should be perpendicular to the TC, not on an angle.
I too think they are Reico jacks.
