T8 33" Grapple

PT does make a rock hammer. It is an add on to the post driver.

I have the post drive and it works like a charm for me. I have thought about the rock breaker, but more for engineering a ground level post driver for retaining walls.

All the best,

No doubt it is dedicated piece of EQ.

I'd like to see a hydraulic hammer for steel fence posts....and a rock hammer attachement (like a jack hammer).

Keep it coming PT!

Peter,
How about some pics of the post driver in action ;~)

I'd second KentT's comments about hydraulic breakers.

Hydraulic hammers come in several flavors;

1. Some are like hydraulic jack hammers: high power, heavy hammers
2. Some are lightweight, high frequency drivers: lightweight hammers
3. Some are low speed pile drivers: basically gravity powered, some with spring assist

The first are very hard on everyone.
The second are used in the hand held drivers, and they work well; they basically vibrate the post into the ground. They can be attached to FEL, or handheld.
The third is the PT post driver, which has a foot that takes a great deal of the shock. They can be cumbersome, since you raise a 500lb weight 8-10' in the air.

If you want to drive a lot of T posts or metal posts, I'd think about #2, which are widely used by utilities and professional fence companies.

I'll try to get photos of the PT driver next time we are out driving posts.

All the best,

Peter

Look for those types of attachments for the mini-skidsteers like Toro Dingos -- they'd be easy to adapt and their GPH requirements are similar to the PT 422 and 425.

I'd caution that everyone that I've talked to who's used a hydraulic breaker/hammer say that they beat the machine to death if you use them very much... regardless of what type machine it is.
