The Chopper Compendium

Hey,
I am trying to build myself a lift table (see pic -its 9' long so I can fit my chopper on it!)) and I'm running into power issues with my cylinder. I am using a 3" bore - 14" stroke cylinder, but it doesn't seem to have the power to raise the table unless I help it up (which kind of isn't the point!). I have tried to remount it in several locations to improve the angle, but it wont work. I have a 60 gal compressor, so air power source isn't the issue. Could it be that the cylinder isn't big enough? and if so, how big of a cylinder would do it?

the cylinder on my lift is 5 inch diameter its a factory made lift it lifts heavy dressers the frameing on it looks very similar to yours not sure if it helps ya

You don't say what ram you have, except it is 3" with 14" stroke. Harbor freight has an 8 ton air over hydraulic ram and it will work your table with ease. They run less than $100.00. My tabe will lift an Ultra Glide converted to a trike with no problem using this ram.

60 gallon tank, but how much pressure? To gain more power, you either need bigger bore cylinder, or more pressure.

My lift is 5" air cylinder also. Shop air is 155 psi on low side - 175 psi on high end.

Air over hydraulics is the way to go.
