2 post lift direct pull vs push type cylinder

[aussieblake]

I am in the market for a 2 post lift, hobby use in my home work shop. Thinking in my head, the lift would be raised all the way up to the top locked position (empty, no vehicle) when not in use. Which may be several weeks in between raising and lowering the lift.

I am concerned about cylinder rods rusting if left exposed for long periods of time (say a month or longer). Which makes the pull type cylinder sound as if it would help mitigate this issue because the cylinder rod is retracted in the up position. Or am I over thinking the issue?

Also any experiences good or bad with pull type cylinders? I read the post on a dealers website regarding the number of seals in a push vs pull cylinder.

Would I be ok with a push type cylinder fully raised for weeks at a time?

FYI I am hoping to buy used, so looking at Craigslist, purple wave, ebay and FB market place, should I be looking anywhere else?

Thanks in advance!

In my experience, leaving the arms all the way up puts them in a prime position to cause concussions and lacerations.

I left a 10k Bendpak at my old shop that had push cylinders, and had read a few posts about bending the rods when a carriage would jam.
I now have a 10k Forward with pull cylinders that are thinner, but the upper end has a vent hose and is self-bleeding.

Well I will often have a vehicle on my lift for a month or more with no issues. No problems with the pistons or seals. Aside from the arms being head knockers I wouldn’t worry about it.
