Looking for Answers about Torin Pneumatic Long Ram Jack - 8-Ton, Model# TQ30806?

Yes. I built a motorcycle lift table using this jack and it works well.

You can run this ram on as little as 90psi, but you will need a fair amount of air volume for it to operate well. I have a 30 gallon air tank on my compressure and the motor started running when the ram was only about 1/4 stretched out. So I found another 30 gallon tank and "daisey-chained" it to my current compressor tank. Now the compressor doesn't kick in till the hydraulic ram is almost fully stretched out.

The ram will not retract automatically. It needs pressure to push it back to a closed position. I know someone who also built a log splitter from a ram similar to this. He used garage door springs to retract the ram. Worked well.

You could feasibly daisy-chain multiple jacks together on one air supply line and operate them with one air controller (a simple blow gun would work). The problem you'd have is in how to lower them all sinultaniously. The lowering valve has to be opened manually. I dont see a way to hook the lowering valves together. If you could overcome this part, then you'd have to have a hugh amount of air volume to operate them together.

No. There is a separate relief than the fill line on the ram jack.

The Torin Pneumatic Long Ram Jack cannot be used upside down.

Eye to eye in the fully closed position is 24.6". In the fully open position it is 43.9".
