Hi folks,
I'm considering building a bucket grapple for my Kubota 7500 FEL and have been looking at various designs and means for powering the grapple.
One interesting thing I ran across is an "electric powered hydraulic cylinder". The neat benefits are the hydraulic circuit is all self contained and doesn't need to be tied into your tractor hydraulics, need to get a hydraulic valve, etc. The grapple direction switching is a mere DPDT switch easily mounted on your dash and the cylinder is powered off your tractor battery- no hydraulic hoses. The grapple (and video showing operation) may be seen at - Extreme Metal Products, LLC
Several questions though: 1) where do you find such "electric powered hydraulic cylinders" ? 2) what are the drawbacks to them over a regular hydraulic cylinder ? 2) Are they significantly weaker than a regular hydraulic cylinder ? When watching the demo video it is hard to see how much "crunching" or "gripping" power the grapple is capable of exerting when closing down on a pile of brush.
Especially I'd like to know some sources of these electric powered hydraulic cylinders to read up on them.
Thanks for any input.
