Anyone have any experience with in-ground telescopic cylinders? How is their performance? Hopefully getting ride of a pair of schindler inverted jacks, but the elevator is right on the river, I'd much rather dig down 12' then 35' with such a high water table. But don't want to recommend to the office/customer a idea thats a great concept but not practical. I suppose they have had a crappy ride all this time from the current set up can't be much worse.

I mean repacking the internals on twin post telescopic is fun enough off the cartop with a 30 foot fall. No way I'd wanna do that hanging the car at the top off the I beam then either rigging off the bottom of the car or putting rail blocks with another beam in-between them.

EElevator - Good thinking

We have a couple of them we put in from EECO. 4500lb cars with 30' travel. No issues yet, they are about 8 years old.

What if they drilled the hole and yall got the jack in in the summer when the rivers down? This summer woulda been the time to do it. We had a drought
