See attached photo, very interesting set up for an elevator that is operated by a hydraulic cylinder.
The hydraulic system, pump, motor and valves are on the second floor due to the building being in a flood zone. Flood happened once back in 1972 so they moved the system upstairs.
Elevator was installed when building was built back in mid-1950's or earlier.
Cylinder ram is at least three stories high, that is how many floors the building has. Ram is one piece, see photo's.
The cylinder is leaking which causes the elevator to creep down when on the first floor in its normal position. The fluid drains into a catch pan with a hose to a bucket.
The cylinder looks to be ok except for the end as you can see in the photo there is fluid at the top and running down. That was from one use while I was there for the demonstration.
While repairing it is beyond my capabilities, I would like to obtain information to pass on to the owner.
** The elevator is only used for moving furniture, no personnel at any time. **
- When does this become a truly unsafe system. The only time it leaks is at the bottom when the elevator is at the first floor.
- Is this a replacement of the top seal only or is it also a symptom of internal leaking at the piston seals.
- Is there an "alternative" fix for the leaking at the top of the ram. See pics, you can see where there are wear marks.
- Any idea of what the cost for that cylinder at three stories high. Not worried about the removal and installation, owner can set that part up. Just worried about the cylinder repair.
