Cherry Picker Engine Hoist

[Shoebox]

I bought a Laron brand engine hoist at the local Farm & Fleet June of '23. It looks like almost everybody's "cherry pickers". I used it once at time of purchase, and wheeled it in the corner. Now I'm using it for an engine swap and I am bummed by how fast it LEAKS DOWN. I may not need to use it again for a bit, but I like quality tools, does anyone have a recommendation for a quality 2 ton hyd ram? I have seen on (forgive me, U tube) that ther're may be one that uses pneumatic pressure for height adjustmant, just asking for any info.......... Thanks guys!
