Why Do Modern Loaders Have Their Lift Cylinders Upside Down?

Renze, is right on!

I thought I made it clear when I said "I see"..

I thought someone else was arguing that cylinder speed is constant no matter which end the oil is pumped into.

Herringchoker, the volume of fluid is not the same on both sides of the cylinder so the speed has to increase and the lift is usually more than the tractor needs before the point of refusal all that other stuff is just wrong,from a bluenoser!!

Yes, retracting the cyl is faster due to what youve said, but, no matter how theyre mounted the cyls extend when lifting the boom.

Larry that was the first Question Why the cylinders were mounted the way they were,SPEED,

The speed is gonna be the same.Like Spyderlk said...the cylinder extends from the base.Don't matter which way it points.

Oil must enter the base end of the lift cylinder in order for the cylinder to be extended hydraulically.
The boom cylinders must be extended in order for the boom to be raised.
This is true regardless of the orientation of the cylinder.
Lifting capacity and speed is identical whether the rod end of the cylinder is pinned to the boom, or the base end is because in either case, oil is pumped into the base end of the cylinder to raise the boom.
There really isn't any question about it.

Paul...I hate to disagree with a neighbour bluenoser and I do realize that the volume of fluid is not the same on both sides of the cylinder (that's why I said there is more force/ less speed when extending than when retracting). The speed is no different when it is extended upward than it would be if it were turned end-for-end and extended downward.

I think Renze has the answer to the OP's question.

Here is what I was trying to say why they reverse the cylinder or Have Their Lift Cylinders Upside Down. Follow this link and check the speed times. Hydraulic Cylinder Speed - Learning Activity

That doesn't change anything. The cylinder still LIFTS by EXTENDING no matter which END is up.
You would have to design a loader that lifted by RETRACTING the cylinder to make it raise faster.
