Is the spare hydraulic capacity normally used for the lift cylinder sufficient to power a hydraulic hoist when the tractor is not doing anything else?

What is the output specs on the lines to the control valve? The hoist uses a 3" diameter hydraulic pump (to be replaced) and has a 3:1 gear reduction. Looking to lift 2000lbs. The hoist's core is about 3" diameter.

Must say I didn't look but I am guessing the cylinder is single acting, so just what kind of valve do we have on there?? 4 way, 3 way, suitable for power up and controlled down-unfurling??

Thanks.

The charge pump is rated 1.5GPM and 500 PSI. With a 3" cylinder it can produce 3.14 * 1.5^2 * 500 = 3532lbs of force. It'll be slow moving, though -- less than 1 inch per second.

The lift cylinder is double acting.

A 3" cylinder holds a lot of fluid so you'll want to make sure that you check your fluid level in your transmission with the cylinder both extended and retracted.

thanks, that pretty much precludes using it for the smallest of Hyd motors.

An electric hoist it is then, saves me a lot of work too.
